1. Keywords Everywhere – Instant Keyword Research in Your Browser

It works with Google, YouTube, Amazon, and other sites, so you don’t need to open extra tools. This helps marketers and SEO experts find the best keywords fast.

2. MozBar – Domain and Page Authority at a Glance
MozBar makes SEO analysis quick. No need to dig through reports—just visit a webpage, and key metrics appear right in the browser.
- Shows domain authority (DA) and page authority (PA).
- Highlights follow and nofollow links.
- Provides on-page SEO insights, including keyword usage.
DA and PA predict a website’s ranking potential. Higher scores mean stronger authority, which can help pages rank better. SEOs use MozBar to size up competitors, track link-building progress, and assess backlink quality.
It’s also useful for checking link attributes. Follow links pass SEO value; nofollow links don’t. Identifying these at a glance makes evaluating a site’s link profile much easier. MozBar is best for SEO professionals who want instant data without interrupting their workflow.
3. SEOquake – Comprehensive SEO Metrics in One Click
SEOquake puts essential SEO data right inside the browser. No need to open extra tabs or switch between tools—it’s all there in one place.
- Runs on-page SEO audits (meta tags, headers, word count).
- Checks keyword density on any webpage.
- Provides backlink and SERP analysis.
This tool is a must for SEOs who need quick insights. It highlights keyword usage (too much? too little?), reveals competition rankings, and evaluates backlinks.
This tool also helps with writing. It shows keyword density in real time, so writers don’t use too many keywords but still keep pages good for SEO.
SEOquake is great for marketers, consultants, and bloggers who need quick and easy SEO data without reading long reports.
4. Ahrefs SEO Toolbar – Backlink and Traffic Insights on Any Page
Ahrefs SEO Toolbar brings powerful link analysis straight into the browser, making it easier to assess competitors and find ranking opportunities.
- Shows backlink profiles (how many? from where?).
- Estimates organic traffic to any webpage.
- Highlights keyword rankings and difficulty scores.
Backlinks help websites rank higher on Google. This tool shows which sites link to a page and whether those links are strong or weak. It also reveals where competitors get their links.
It’s useful for tracking keywords, too. Instead of opening Ahrefs’ main site, users can check traffic and rankings right on the page. SEO experts use it to find good link opportunities and improve search rankings.
5. Meta SEO Inspector – Instant Metadata Analysis
Meta SEO Inspector pulls metadata straight from a webpage, showing details like title tags, descriptions, and header structure. These elements shape how a page appears in search results—and missing or duplicate tags can hurt rankings.
- Extracts metadata in real-time.
- Flags SEO issues (missing tags, duplicate content).
- Checks Open Graph and Twitter Card data.
Search engines rely on metadata to understand page content. If title tags are too long, they get cut off. If descriptions are missing, search engines pull random snippets. Meta SEO Inspector highlights these problems instantly, making optimization easier.
The tool also checks how links look when shared on social media (like Facebook and X). It makes sure the right images and text show up. SEO experts, developers, and content creators use it to fix these settings. This helps more people see and click their links.
6. Check My Links – Find and Fix Broken Links Fast
Broken links frustrate users and weaken SEO. Check My Links scans a webpage, instantly highlighting dead links that need fixing.
- Detects broken links (404 errors, redirects).
- Color-codes valid and invalid links.
- Speeds up site audits and maintenance.
Search engines view broken links as a sign of poor upkeep, which can impact rankings. This tool helps webmasters maintain a clean, user-friendly experience. It highlights valid links in green and broken ones in red, making fixes quick and painless.
This tool is great for big websites and pages with lots of content (like blogs with many links). SEO experts and content managers use it to find and fix old or broken links. This helps visitors move around the site without running into errors. It also makes search engines happy, which can improve rankings.
7. PageSpeed Insights – Optimize Site Performance
PageSpeed Insights evaluates how fast a webpage loads and pinpoints areas for improvement. Slow sites frustrate users and hurt SEO rankings, making this tool essential for performance optimization.
- Measures load times for mobile and desktop.
- Identifies factors slowing down a page.
- Suggests fixes like image compression and caching.
Google cares a lot about speed. If a page takes more than three seconds to load, people leave. PageSpeed Insights checks how fast a website loads and gives it a score from 0 to 100. A score under 50 means big problems.
The tool measures two key things:
- First Contentful Paint (FCP): How fast the page shows anything.
- Largest Contentful Paint (LCP): How long it takes to load the main content.
Fixing slow pages often means making servers respond faster, improving JavaScript, and using browser caching. SEO experts and developers use this tool to speed up websites, keeping visitors happy and rankings high.
8. SimilarWeb – Traffic and Competitor Analysis Made Easy
SimilarWeb estimates website traffic, audience behavior, and engagement trends. It’s a powerful tool for analyzing competitors and refining SEO strategies.
- Breaks down traffic sources (organic, paid, social, direct).
- Reveals top-performing keywords and referral sites.
- Compares multiple domains side by side.
Knowing where a competitor’s visitors come from is half the battle. SimilarWeb categorizes traffic sources, showing whether a site relies more on search, social media, or direct visitors. That helps businesses adjust their marketing focus.
The tool also tracks bounce rates and average visit duration, two metrics that indicate whether a website keeps users engaged. Higher engagement signals quality content—something search engines reward with better rankings.
SEO teams use SimilarWeb to benchmark their own traffic against industry leaders. If a competitor gains traction through a specific traffic source, adjusting strategy to match can help level the playing field. Business owners, digital marketers, and analysts all benefit from these insights.
9. SEO Minion – A Versatile SEO Assistant
SEO Minion simplifies on-page SEO tasks by checking for errors, previewing search engine results, and identifying broken links. It’s a practical tool for quick audits without switching between platforms.
- Highlights missing or duplicate meta tags.
- Analyzes SERP snippets for better click-through rates.
- Detects broken links within seconds.
On-page SEO is always changing—meta descriptions update, links break, and rankings go up or down. SEO Minion helps spot these problems fast.
Its SERP preview tool shows how a page will look in search results before it goes live. This helps improve clicks.
It also has a broken link checker. Instead of checking links one by one, it highlights bad ones right away. This keeps websites easy to navigate. Webmasters and marketers use it to fix SEO issues quickly.
10. Ghostery – Privacy and Marketing Insights in One Tool
Ghostery blocks ad trackers while revealing which marketing technologies run on a website. That makes it useful for both privacy-conscious users and digital marketers looking to analyze competitor tracking strategies.
- Blocks third-party trackers and cookies.
- Speeds up page loading times by reducing scripts.
- Shows detailed insights into advertising networks.
Websites collect an overwhelming amount of user data—often without visitors realizing it. Ghostery exposes these trackers, allowing users to block them for a faster, more private browsing experience. Less tracking also means fewer ads following users across the web.
For marketers, Ghostery provides a different benefit. It uncovers the tools competitors use for analytics, ad targeting, and conversion tracking. Seeing which ad networks and retargeting platforms run behind the scenes can help businesses refine their own digital strategies. Whether it’s for privacy or competitive research, Ghostery is a powerful tool for those who want more control over online tracking.
