Search Engine Marketing (SEM) Guide: Strategies, Ad Types, and Optimisation Tips

Search Engine Marketing (SEM) enables businesses to reach users actively seeking solutions, products, or services online. By securing paid placements on search engine results pages, SEM effectively boosts brand visibility, drives qualified traffic, and delivers measurable outcomes.

Whether you are new to paid search or refining an existing strategy, this guide provides actionable steps and best practices tailored for success in the Singapore market. You’ll gain clarity on SEM ad types, keyword targeting, bidding strategies, campaign setup, and ongoing optimisation techniques that help drive measurable results.

What is Search Engine Marketing (SEM)?

Search Engine Marketing (SEM) is a digital advertising approach in which businesses pay to have their ads appear on search engine results pages (SERPs). The goal is to appear when someone searches for a product or service you offer.

SEM typically employs a Pay-Per-Click (PPC) model through platforms such as Google Ads or Microsoft Ads. You only pay when someone clicks on your ad. This makes the SEM budget-efficient and results-driven.

Why SEM Works

SEM is effective because it engages users at the critical point of intent, when they are actively searching for products or services. This makes it a powerful tool for driving qualified traffic, leads, and sales quickly and efficiently.

SEM vs SEO

SEM vs SEO

Recognising the differences between Search Engine Marketing (SEM) and Search Engine Optimisation (SEO) is crucial for shaping an effective digital strategy. Both are focused on search engine visibility, but they operate under different mechanisms and serve distinct business needs.  

Metric	SEM	SEO
Traffic Source	Paid	Organic
Speed	Immediate visibility	Requires long-term effort
Cost	Cost per click	No direct cost per visit
Lifespan	Runs while the budget is active	Builds equity over time
Control	Full targeting control	Influenced by search engines

Why Use SEM?

Search Engine Marketing provides a direct and cost-effective way to reach users actively seeking your products or services. It is particularly valuable in environments like Singapore, where search behaviours are fast-moving and intent-driven. Below are key reasons businesses across industries invest in SEM:

1. Immediate Visibility

Unlike SEO, which often takes months to show results, SEM offers immediate visibility, putting your ads live within hours of launching a campaign. This makes it particularly effective for quick-turnaround initiatives like product launches, seasonal promotions, or time-sensitive events.

2. Precise Targeting

SEM gives full control over who sees your ads. You can target by keyword intent, location, time of day, device, language, demographics, and even audience behaviour. This ensures your budget goes to high-relevance segments.

3. Transparent, Measurable Results

Every aspect of your campaign, from impressions and clicks to conversions and cost per acquisition, is trackable and measurable. Google Ads provides detailed analytics to optimise performance in real-time.

4. Budget Flexibility and Scale

SEM campaigns work across all budget levels. Start with a small test, gather data, and then scale based on performance. You can also pause or adjust spending as market conditions change.

5. Strong Fit for Competitive Markets

In competitive verticals such as insurance, real estate, or e-commerce, organic ranking alone is often insufficient to achieve success. SEM helps you maintain visibility on search engine results pages, especially for transactional keywords where purchase intent is high.

Types of SEM Ads

1. Search Ads

These are text-based advertisements displayed on search engine results pages (SERPs) in response to specific user keyword searches. They are highly targeted, appearing to users actively looking for related products or services. Search ads are the most common SEM format, offering high visibility and flexible budgeting options.

Best for:

• Capturing high-intent users who are ready to take action
• Generating direct leads, inquiries, or conversions
• Promoting services, offers, or content to users actively searching

Features:

• Appear with a clear “Ad” label at the top or bottom of SERPs
• Include headlines (up to 30-35 characters), descriptions (up to 90 characters), and ad extensions (site links, callouts, structured snippets) to enhance visibility and engagement
• Can be optimised over time with Responsive Search Ads (multiple headlines/descriptions tested automatically) and Dynamic Search Ads (automatically generated from website content)
• Allow precise keyword targeting and bidding strategies

Limitations:

• Highly competitive, especially for broad or short-tail keywords, driving up costs
• Ad placement depends on Quality Score (relevance, landing page experience, CTR) and bid amount, requiring ongoing optimisation
• Text-only format limits creative expression compared to visual ads

Example:
A user searches “corporate tax consultant Singapore,” and your ad appears above all organic listings, directing them to your consultation booking page.

2. Display Ads

Visual ads such as banners, images, or rich media appear on websites, apps, or social media platforms within a display network. Unlike search ads, they target audiences based on demographics, interests, or behaviour rather than search queries.

Best for:

• Building brand awareness and recognition among broad or niche audiences
• Retargeting users who previously visited your site but did not convert
• Promoting special offers or new product launches to a wider audience

Features:

• Support multiple formats: static images, animated GIFs, and video
• Targeting options include demographics, interests, topics, placements, and remarketing lists
• Can be integrated with Google Display Network or similar platforms for wide reach
• Often used alongside search ads for a full-funnel marketing approach
  

Limitations:

• Generally lower click-through rates (CTR) compared to search ads due to less immediate user intent
• Less effective for direct conversions; better suited for awareness and engagement
• Ad blindness, also known as banner fatigue, can reduce effectiveness over time.
  

Example:

After visiting a software pricing page, a user may see your banner ad on news sites like The Straits Times or CNA, reminding them of your product and encouraging return visits.

3. Shopping Ads (Product Listing Ads)

These ads feature product images, prices, and descriptions directly in search results, making them ideal for e-commerce businesses to drive sales by visually promoting their products.

Best for:

• E-commerce businesses with multiple products or SKUs
• Retailers aiming to drive online sales through direct product promotion
• Businesses want to showcase competitive pricing and product details up front

Features:

• Ads are generated from a Google Merchant Centre product feed, which must be regularly updated with accurate product data.
• Include product image, price, store name, and sometimes promotions or ratings.
• Highly visual and appear prominently in search results, often above text ads
  

Limitations:

• This is only applicable to physical products, not services or digital goods.
• Requires detailed and frequently updated product data feeds
• It can be competitive and costly in popular product categories
• Requires detailed product data and frequent updates
• Only applicable to physical goods
  

Example:

A user searches “buy standing desk Singapore,” and your product ad appears with an image, price, and link to purchase directly from your online store.

4. Video Ads

Ads that run on YouTube or Google video partners. These may play before, during, or after content.

Best for:

• Telling a compelling visual story about your brand or product
• Demonstrating product features or tutorials
• Building brand recall and awareness through engaging content
  

Features:

• Multiple formats: skippable ads, non-skippable ads, bumper ads (short 6-second videos), in-feed video ads, and masthead ads (reserved for large campaigns)
• Targeting by user behaviour, interests, demographics, and placements
• Charged on a cost-per-view or cost-per-thousand-impressions basis, depending on the format
  

Limitations:

• Requires investment in video production and creative resources
• It is less effective for immediate conversions since users may not be in a buying mindset
• Some formats are non-skippable, which can annoy users if not well-targeted

Example:

Before a user watches a YouTube review of “best wireless earbuds,” your 15-second promotional video plays, highlighting your product’s unique features.

5. Local Ads

Specialised paid advertisements are designed to help businesses with physical locations or service areas reach nearby customers effectively. These ads appear prominently on platforms such as Google Search and Google Maps when users search for products or services within a specific geographic area.

Best for:

• Businesses with physical storefronts or service areas
• Retail stores, restaurants, clinics, local service providers (plumbers, electricians)
• Businesses aiming to increase foot traffic, local leads, or phone inquiries

Features:

• Show business location, hours, photos, reviews, and directions
• Enable direct calls from ads with call tracking
• Use assets from Google Business Profile for rich ad content
  

Limitations:

• Limited reach outside the targeted geographic area
• Requires a verified and optimised Google Business Profile
• It is less effective for online-only businesses or those without a physical presence
• It can be competitive and costly in densely populated or high-demand areas

Example

A local bakery uses Local Ads to appear on Google Maps and Search when users nearby search for “fresh bread near me.” The ad shows the bakery’s address, hours, photos, and a “Call Now” button, helping drive in-store visits and phone orders.

6. Remarketing/Retargeting Ads

Remarketing Ads target users who have previously visited your website but did not convert, encouraging them to return and complete a purchase or take a desired action.

Best for:

• Recovering abandoned carts in e-commerce.
• Retargeting visitors of key landing pages or product pages
• Increasing ROI by focusing on warm, familiar audiences

Features:

• It can be shown across Search, Display, and YouTube networks
• Custom audiences are created based on user behaviour (page visits, time spent, actions taken)
• Flexible, creative options tailored to user interests and past interactions

Limitations:

• Requires sufficient website traffic and proper tagging to build effective audiences
• Privacy regulations and cookie policies can limit the tracking and targeting capabilities of websites.
• Overexposure can lead to ad fatigue if frequency is not managed

Example:

A user visits your pricing page but leaves without making a purchase. Days later, they see a display ad offering a 10% discount, prompting them to return and make a purchase.

How SEM Works

SEM works by bidding on keywords relevant to your business, creating targeted ads that appear on search engine results pages, and paying only when users click on them. It also continuously optimises campaigns based on performance data. This strategic approach helps businesses reach potential customers precisely when they are searching, maximising visibility and conversions.

Here is a detailed explanation of how SEM works:

1. Keyword Research

The process begins with identifying the right keywords, the words or phrases potential customers use when searching for products or services. Marketers use tools like Google Keyword Planner or SEMrush to find keywords that strike a good balance of search volume, relevance, and competition. Selecting effective keywords ensures ads are shown to users actively looking for what the business offers.

2. Ad Creation

Advertisers create text-based ads that typically include:

• Headlines or title tags
• Descriptive text summarising the offer or value proposition
• Calls to action (e.g., “Buy Now,” “Get a Quote”)
• Display URLs linking to relevant landing pages.

These ads are designed to be compelling and relevant to the search query, encouraging users to click.

3. Bidding and Auction System

SEM operates as an auction where advertisers bid on keywords to compete for ad placement. However, the highest bid doesn’t always win. Search engines like Google use a combination of bid amount and Quality Score to determine ad rank. Quality Score measures the relevance and quality of the ad, keywords, and landing page, as well as the expected click-through rate (CTR). A high-quality ad can achieve better placement at a lower cost.

4. Ad Placement

Winning ads appear in prominent positions on the SERP, often at the top or bottom, clearly labelled as “Ad” or “Sponsored.” This prime placement increases visibility and the likelihood of clicks from users actively searching for related products or services.

5. Pay-Per-Click Model

Advertisers only pay when a user clicks on their ad, making SEM cost-efficient. This model ensures marketing budgets are spent on actual engagement rather than mere impressions.

6. Tracking and Optimisation

Once the campaign is live, marketers continuously monitor key metrics such as:

• Clicks and impressions
• Cost per click (CPC)
• Conversion rates (e.g., purchases, sign-ups)
• Return on ad spend (ROAS)

This data-driven approach allows for ongoing optimisation, adjusting bids, refining keyword lists, tweaking ad copy, and improving landing pages to maximise effectiveness and ROI.

Additional Insights

• SEM ads often include ad extensions (site links, call buttons, location info) to enhance visibility and user engagement.
• Geographic and device targeting allow ads to be shown to the most relevant audiences.
• SEM complements SEO by providing immediate visibility, whereas SEO builds organic presence over time.
• Platforms like Google Ads and Microsoft Ads dominate SEM, offering self-serve tools for campaign setup and management.

Keyword Match Types

Keyword match types determine how closely a user’s search query must align with your chosen keywords for your ads to appear. Choosing the right match type helps balance reach and precision, ensuring your ads show to the right people while minimising wasted spend.

Broad Match

Broad match casts the widest net, allowing your ads to appear for a wide variety of related search queries. It uses Google’s understanding of synonyms, related searches, and user intent to match your ads beyond exact keywords. This is useful for generating large traffic volumes and discovering new keyword opportunities, but can lead to irrelevant clicks and wasted budget if not monitored closely.

Phrase Match

Phrase match offers more control than broad match by requiring the exact keyword phrase to appear in the search query, preserving word order. This helps balance reach and relevance, making it useful when you want to target specific search intents but still capture variations with additional words. It reduces irrelevant traffic compared to broad matches, but can still show ads on longer or slightly varied searches.

Exact Match

Exact match provides the highest precision by showing ads only when the search query exactly or very closely matches your keyword. It’s ideal for campaigns focused on high-intent users and optimising ROI, as it limits impressions to highly relevant searches. However, it restricts reach and may miss some relevant queries that a phrase or broad match would capture.

Negative Match

Negative keywords are essential for excluding irrelevant or unwanted search terms that might trigger your ads. This helps improve campaign efficiency by preventing wasted spend on unrelated traffic. For example, if you sell premium products, you might exclude terms like “cheap” or “free.” Proper management is crucial to avoid accidentally blocking valuable queries.

Choosing the right keyword match types is critical for optimising your SEM campaigns. Broad match maximises reach but risks irrelevance, phrase match balances reach and precision, exact match maximises relevance but limits traffic, and negative match helps refine targeting by excluding unwanted searches.

Effective SEM management involves combining these match types strategically:

• Use broad matches to initially explore and expand your reach.
• Add phrase and exact match keywords to target high-value queries precisely.
• Continuously add negative keywords to filter out irrelevant traffic and improve ROI.

This layered approach helps maximise conversions while controlling costs and maintaining relevance.

Here is a detailed explanation of Keyword Match Types in SEM, including their advantages, limitations, and examples:

Match Type	Best For	Limitations	Example
Broad Match	Reaching the widest audience, discovering new keyword variations, and running early-stage campaigns.	Less precise. Can trigger irrelevant traffic. Higher risk of wasted spend.	Keyword: student loans → triggers education loan, student credit, interest rate on student loans.
Phrase Match	Balancing reach and relevance, targeting more specific queries while still allowing some variation.	May still show ads on less relevant queries if the phrase is part of a longer search, but is less broad than a broad match.	Keyword: “McDonald’s burger” → triggers McDonald’s burger near me, best McDonald’s burger.
Exact Match	Highly targeted campaigns, maximising relevance and ROI, controlling spend on specific queries.	Narrow reach; fewer impressions; may miss some relevant searches if phrasing differs.	Keyword: [Headphones] → triggers headphones, headphone, but not best headphones for running.
Negative Match	Avoiding irrelevant clicks, saving budget, and refining targeting.	It must be carefully managed to avoid inadvertently excluding valuable traffic.	Negative keyword: -blackboard excludes searches for blackboard when selling whiteboards.

Creating Your First SEM Campaign

While a new SEM campaign from scratch may appear complicated, a systematic approach makes it highly manageable and rewarding. The foundation of every successful campaign lies in its setup. Each decision you make at this stage affects targeting, visibility, budget control, and conversion potential. This section breaks down everything you need to start, the choices you’ll have to make at each step, and the best tips to make sure you don’t waste money or attract the wrong kind of traffic.

Step 1: Open a Google Ads Account

Before launching ads, you need to set up a Google Ads account. During setup, select your business goal (e.g., website traffic, lead generation, online sales), define your business location, set your billing method, and configure currency. This forms the foundation of your ad infrastructure and reporting.

Account Structure

It’s essential to understand the structure of a Google Ads account. Google Ads and most paid search platforms use a layered structure to manage campaigns efficiently. Each layer has a specific role: the campaign defines your objective, the ad group organises themes, and the ads target user queries with specific messages.

Campaign > Ad Group > Keywords & Ads

Step 2: Do Keyword Research

Effective campaigns begin with keyword intent. Utilise tools like Google Keyword Planner, SEMrush, or Ahrefs to identify search terms that align with your offer. Prioritise:

• High commercial intent terms (e.g., “book dentist appointment”)
• Local keywords (e.g., “electrician Toa Payoh”)
• Long-tail keywords for lower competition and better quality traffic. Group keywords by theme or intent to later organise them into ad groups.

Step 3: Write Compelling and Relevant Ad Copy

Your ads should clearly address the searcher’s intent and highlight your unique selling points. A good ad includes:

• A clear, relevant headline: It should be concise, include important keywords, and immediately convey the benefit or solution you offer. For example, instead of a generic headline like “Accounting Software,” use “End Paperwork Hassles with Our Accounting Software.”
• Descriptive text highlighting your unique selling points: Use the description to expand on your headline by emphasising the benefits and features that differentiate your product or service. Focus on what’s in it for the customer rather than just listing features.
• A strong call to action (CTA): Encourage users to take the next step with clear directives such as “Shop Now,” “Get a Free Quote,” or “Book a Demo Today.” 
• Ad extensions: Utilise sitelinks, callouts, location info, and structured snippets to provide additional information and increase your ad’s prominence on the search results page. Extensions enhance visibility and provide users with additional reasons to engage.

Step 4: Set Up Targeting and Bidding

Proper targeting and bidding strategies ensure that your ads reach the right audience at the right time, while maximising your budget efficiency.

• Define geographic locations: Specify the cities, regions, or countries where your ads should appear. Geo-targeting helps you focus on areas where your potential customers are located, reducing wasted spend on irrelevant locations.
• Choose device targeting: Analyse your audience’s behaviour to decide if your ads should appear on desktop, mobile, or tablet devices.
• Select a bidding strategy: Choose between manual bidding (where you control bids per keyword) or automated bidding strategies such as Target CPA (cost per acquisition) or Maximise Conversions. Automated bidding uses machine learning to optimise bids in real time for better results.
• Adjust bids by factors: Modify bids based on high-value locations, peak times of day, or device types to maximise your campaign’s effectiveness and return on investment.

Step 5: Build Landing Pages

Your landing pages are where clicks turn into conversions. They must provide a seamless and relevant experience aligned with your ads.

• Match ad message and keywords: Ensure the landing page content closely reflects the ad copy and targeted keywords. This relevance improves Quality Score and increases the likelihood of conversion.
• Fast-loading and mobile-friendly: Optimise page speed and ensure the design is responsive so users on any device have a smooth experience. Slow or poorly designed pages increase bounce rates and reduce conversions.
• Clear call to action: Make it obvious what action you want visitors to take. Use prominent buttons and simple forms to reduce friction.

A well-optimised landing page not only improves user experience but also positively impacts your ad ranking and cost efficiency.

6. Launch and Monitor Your Campaign

Once your campaign is live, active monitoring is crucial to maintaining performance and controlling costs.

• Track key metrics: Monitor impressions, clicks, click-through rate (CTR), conversions, and overall spend. These indicators help you understand how well your ads are performing.
• Use negative keywords: Regularly review search terms triggering your ads and add irrelevant or low-performing keywords as negatives. This prevents your ads from showing on unrelated queries, saving budget and improving targeting.
• Conversion tracking: Implement tools like Google Ads conversion tracking or Google Analytics to measure actions users take after clicking your ads. Tracking conversions is crucial for assessing ROI and optimising campaigns effectively.

8. Analyse and Optimise

Optimisation is an ongoing process that requires data-driven decision-making to continually improve campaign performance.

• Pause or adjust underperforming keywords and ads: Identify keywords or ads with low CTR or poor conversion rates and either pause them or refine their targeting and messaging.
• Refine ad copy and landing pages: Use insights from user behaviour and A/B testing to improve your ads and landing pages. Small changes in wording, layout, or CTA can significantly boost results.
• Adjust bids and targeting: Reallocate budget toward high-performing keywords, locations, or devices. Lower bids or exclude segments that do not convert well.
• Continuously update negative keywords: Keep filtering out irrelevant traffic to maintain campaign efficiency.

Regularly reviewing your campaign, ideally on a weekly or biweekly basis, allows you to catch issues early and capitalise on opportunities, ensuring your SEM efforts deliver maximum impact.

SEM Performance Metrics

Tracking performance is essential for understanding whether your SEM campaigns are actually delivering business value. Every click, impression, and conversion generates data that can inform smarter decisions and better budget allocation. 

1. Impressions

Impressions refer to the number of times your ad is displayed on search engine results pages (SERPs) or partner websites. This metric indicates your ad’s visibility and reach. A high impression share, ideally between 60% and 80%, indicates that your ads are appearing frequently for your target keywords.

Optimisation Tips:

• Utilise precise targeting (demographics, interests, and locations) to ensure that impressions reach relevant audiences.
• Improve ad quality and relevance to increase impression share.
• Increase bids cautiously to improve ad position and visibility.

2. Clicks

Clicks represent the number of times users click on your ad to visit your website or landing page. This metric shows user engagement and interest in your offer. Generally, the more clicks, the more opportunities for conversions.

Optimisation Tips:

• Write compelling, relevant ad copy with clear calls to action.
• Use ad extensions to make ads more appealing.
• Target the right audience to attract qualified clicks.

3. Click-Through Rate (CTR)

Click-through rate (CTR) is the percentage of impressions that result in clicks, calculated by dividing the number of clicks by the number of impressions and then multiplying by 100. CTR reflects how well your ad resonates with users. A high CTR improves your Quality Score, which can lower your cost per click (CPC) and improve your ad rank.

Optimisation Tips:

• Continuously test and refine ad copy and headlines.
• Use targeted keywords and relevant ad extensions.
• Align ads closely with user intent.

4. Cost Per Click (CPC)

Cost Per Click (CPC) is the average amount you pay for each click on your ad. This metric affects your budget and return on investment. Lower CPC allows you to get more clicks within your budget.

Optimisation Tips:

• Improve Quality Score by enhancing ad relevance and landing page experience.
• Use smart bidding strategies to optimise costs.
• Focus bids on high-performing keywords and audiences.

5. Conversion Rate (CVR)

Conversion Rate is the percentage of clicks that result in a desired action, such as a purchase, sign-up, or inquiry. It is calculated by dividing conversions by clicks and then multiplying the result by 100. Conversion rate measures the effectiveness of your ads and landing pages in driving business outcomes.

Optimisation Tips:

• Ensure landing pages are relevant, fast, and user-friendly.
• Use strong calls to action and minimise friction in the conversion process.
• Test different landing page elements to improve performance.

6. Cost Per Conversion (CPA)

Cost Per Conversion (CPA) is the average cost to acquire a conversion, calculated by dividing total spend by the number of conversions. This metric helps you understand the profitability of your campaigns. A lower CPA means better efficiency.

Optimisation Tips:

• Optimise targeting to reach high-intent users.
• Pause or adjust underperforming keywords and ads.
• Utilise automated bidding strategies that focus on CPA goals.

7. Quality Score (Google Ads Specific)

Quality Score is Google’s rating of your ad’s relevance, expected CTR, and landing page experience, scored from 1 to 10. A higher Quality Score leads to better ad placements and lower CPCs.

Optimisation Tips:

• Align keywords, ad copy, and landing page content closely to ensure a seamless user experience.
• Improve landing page speed and mobile usability.
• Continuously optimise ad relevance and user experience for enhanced performance.

8. Impression Share

Impression Share is the percentage of total eligible impressions your ads receive compared to the total available impressions. A low impression share indicates missed opportunities due to budget or rank limitations.

Optimisation Tips:

• Increase bids or budget to capture more impressions.
• Improve Quality Score to increase ad rank.
• Focus on high-priority keywords and audiences.

9. Return on Ad Spend (ROAS)

Return on Ad Spend (ROAS) measures the revenue generated per dollar spent on ads. This metric indicates the overall profitability of your SEM campaigns.

Optimisation Tips:

• Track and attribute conversions accurately.
• Allocate budget to campaigns or keywords with the highest ROAS.
• Optimise landing pages and conversion funnels to maximise revenue.
