Alt text leads: Google calls it the most important attribute for image metadata and tells site owners not to stuff it with keywords ([Google Search Central, image SEO best practices](https://developers.google.com/search/docs/appearance/google-images)). This guide sets out Aemorph's ten-practice image SEO checklist for Singapore sites.

Crisp images draw the click, while heavy files drag the page down. According to Google, images are often the largest contributor to overall page size; it recommends [PageSpeed Insights](https://pagespeed.web.dev/) for checking speed. ## Which Search Engine Sets the Rules for Singapore Image SEO? **Google held 92.16% of search engine market share in Singapore in September 2026, against 4.53% for Bing ([StatCounter](https://gs.statcounter.com/search-engine-market-share/all/singapore)), so Google's own image guidance is the standard Singapore image work follows.** Aemorph tracks Singapore clients' image and page issues in Google Search Console. | Measure | Figure | Market and date | Source | | --- | --- | --- | --- | | Google search engine market share | 92.16% | Singapore, September 2026 | StatCounter | | Bing search engine market share | 4.53% | Singapore, September 2026 | StatCounter | | Internet users | 5.78 million, 98.4% of the population | Singapore, as of October 2025 | DataReportal | | Monthly searches for "image alt text seo" | About 10 | Singapore, 24 October 2026 | Ahrefs Keywords Explorer | *Sources: StatCounter, Singapore, September 2026; [DataReportal](https://datareportal.com/reports/digital-2026-singapore), as of October 2025; Ahrefs, 24 October 2026.* ## Which Ten Image SEO Practices Matter for Singapore Sites? **Ten practices decide what each image is, how it is described and how fast it loads.** | # | Practice | What you do | Primary effect | Where it applies | | --- | --- | --- | --- | --- | | 1 | Use original images | Show your real products, people, outlets and data | Differentiation, brand recognition | Every page with a photo | | 2 | Choose the right format | Fit the format to what the image is | File size, quality | Every image | | 3 | Compress every file | Resize to display width, then compress | Load speed | Every image | | 4 | Name files descriptively | Rename camera defaults in plain words | Context for search engines | Every image | | 5 | Write unique alt text | Describe this particular image in a sentence | Image search, accessibility | Every meaningful image | | 6 | Serve responsive sizes | Use srcset or picture with a src fallback | Load speed on mobile | Large and hero images | | 7 | Add images to a sitemap | List images Google fails to find | Discovery | Script-loaded or CDN-hosted images | | 8 | Add structured data | Mark up the image property | Rich results eligibility | Product, recipe and video pages | | 9 | Lazy load below the fold | Defer images outside the first screen | Initial load speed | Long pages and galleries | | 10 | Test speed after changes | Measure before and after | Verification | Each batch of changes | *Ten image SEO practices for Singapore websites. Source: Google Search Central, image SEO best practices, October 2026.* ### 1\. Use original images, and keep AI-generated ones honest **Original photos and graphics distinguish your pages from every site using the same stock library, and an AI-generated product image meets the same advertising standard as a photograph.** Show your real products, people, outlets and figures; original visuals also give other sites a reason to credit you with a link. The Advertising Standards Authority of Singapore's [Singapore Code of Advertising Practice](https://asas.org.sg/About/Code) rests on the premise that all advertisements are legal, decent, honest and truthful. ASAS [received 379 pieces of advertisement feedback in 2025](https://asas.org.sg/News/Post/407/Media-Release-ASAS-Sees-Rise-in-Feedback-on-Use-of-AI-in-Advertising), seven of them about advertisements that used generative AI, more than double the three received across 2023 and 2024. More on the Code is in the [ASAS advertising code guide](https://aemorph.com/en-sg/guides/asas-advertising-code/). *General guidance, not legal advice.* ### 2\. Choose the right format **Google Search supports BMP, GIF, JPEG, PNG, WebP, SVG and AVIF, and asks that the file extension match the actual file type ([Google Search Central](https://developers.google.com/search/docs/appearance/google-images)).** Choose JPEG or WebP for photographs, PNG for graphics with transparency and SVG for logos and icons; move to AVIF when your tooling handles it and the saving repays the effort. ### 3\. Compress every file **Compress images before upload so that every page reaches Singapore visitors faster.** Resize to the widest size your layout displays, increase compression until the quality drop shows, then ease back one notch. Make compression automatic in your build or media library so nobody forgets it. ### 4\. Name files descriptively **Name each file in a few plain words that describe it, such as the product or subject, joined by hyphens.** Google treats the file name as a light hint about the subject: a clear name helps, though it carries little ranking weight. Rename camera defaults such as IMG\_2041. ### 5\. Write unique alt text **Alt text describes what an image shows, in an ordinary sentence, for people who are unable to see it.** Screen readers speak it aloud, and search engines read it to work out what the image is. Describe the particular image, leave decorative images with empty alt text, and avoid repeating the same keyword phrase across a page. ### 6\. Serve responsive sizes **Use the picture element or the srcset attribute so each device fetches a fitting size, and keep a fallback in the src attribute, as Google recommends.** A mobile visitor then avoids downloading a desktop-sized hero image. ### 7\. Add images to a sitemap **An image sitemap points Google to images it otherwise overlooks, including images on a CDN under another domain.** Create one when your images load through scripts or sit inside galleries the crawler skips. ### 8\. Add structured data **Image structured data makes an image eligible for badges and rich results in Google Images, and Google lists the image property as required for that eligibility.** Choose the markup for your content type, such as product, recipe or video, and make every value match the visible page exactly. ### 9\. Lazy load below the fold **Lazy loading postpones images until the visitor scrolls close to them, which speeds up the first load.** Keep the main hero image out of lazy loading, because deferring it delays the largest element on screen. Check the rendered page to make sure lazy-loaded images remain in the HTML Google processes. ### 10\. Test speed after changes **Measure each batch of image changes in PageSpeed Insights before and after, comparing largest contentful paint and total page weight.** When neither number moves, look again at the cause. ## How Do Images Relate to Your Wider On-Page Work in Singapore? **Image checks are one stage of a full on-page review, next to titles, headings, content and speed, and the stages together decide how many Singapore buyers find your pages and stay.** Put image checks into your crawl export so missing alt text and oversized files show in the same report as everything else. Work through the [on-page SEO audit guide](https://aemorph.com/en-sg/guides/on-page-seo-audit/), apply the [anchor text guide](https://aemorph.com/en-sg/guides/anchor-text/) to alt text on linked images, and compare tools in the [image optimisation tools guide](https://aemorph.com/saas-tools/image-optimisation/). > **Case study · Ecommerce, Singapore** > > **HiBye grew organic traffic 223% in 4 months.** > > Monthly organic visits rose from 325 to 1,049, a short engagement that is not annualised.
