Links are one of the most important ranking factors in SEO. Most discussions focus on text links, where a clickable word or phrase points to another page. But many links on the web are images: logos, banners, product thumbnails, infographics, and buttons. This raises an important question for marketers and website owners: do image links count for SEO? The answer is yes. Image links can pass authority and relevance signals just like text links. However, the way search engines interpret them is slightly different, and understanding these differences helps you get the most value from every link, whether you earn it or create it.

How Search Engines Treat Image Links
When a crawler encounters an image wrapped in a link, it follows the link to the destination page just as it would with a text link. Google has confirmed that image links can pass PageRank. The key difference lies in anchor text. With a text link, the clickable words serve as anchor text, giving search engines a clear signal about the destination page's topic. With an image link, there is no visible text, so Google uses the image's alt attribute as the equivalent of anchor text.
Why Alt Text Is Critical for Image Links
The alt attribute describes the image for users who cannot see it, including people using screen readers, and for search engines. When an image functions as a link, its alt text should describe the destination or purpose of the link, not just the visual content. For example, a logo that links to the home page might use alt text containing the company name. A product thumbnail linking to a product page should describe that product. Without alt text, an image link provides little contextual information, which weakens its relevance value.
Image Links as Backlinks
Image backlinks from other websites can be valuable. Common sources include:
- Infographics: When other sites embed your infographic and link back to you.
- Logos and badges: Partner pages, award listings, and sponsorships often display linked logos.
- Product images: Reviews and roundups may link product photos to your store.
- Banner placements: Some partnerships include linked banners, though paid ones should be marked appropriately.
These links count, especially when they come from relevant, authoritative websites. However, a healthy backlink profile should include a natural mix of text and image links. If you have the opportunity, a contextual text link within editorial content is often more powerful because of the surrounding relevant text.
Image Links in Internal Linking
Image links are common within websites, particularly in navigation, product grids, and featured content blocks. They help users move through your site and distribute authority between pages. To maximize their SEO value, ensure that each linked image has descriptive alt text, that important pages also receive text links, and that image links are built with standard HTML anchors rather than JavaScript events that crawlers may not follow.
What Happens When a Page Has Both Image and Text Links?
Many pages link to the same destination more than once, for example with a product image and a product title. Historically, SEO testing suggested that search engines might only count the anchor text of the first link on a page to a given URL. While search engines have evolved and do not publish exact rules, it is a sensible practice to make sure all links to the same page carry relevant, descriptive context. If the image link appears first, make sure its alt text is meaningful.
Nofollow and Sponsored Attributes Still Apply
Just like text links, image links can carry rel attributes such as nofollow, sponsored, or ugc. Paid banner placements should use the sponsored attribute to comply with search engine guidelines. Links marked as nofollow are treated as hints and may not pass authority, though they can still deliver referral traffic and brand visibility.
Best Practices for SEO-Friendly Image Links
- Always add concise, descriptive alt text to linked images.
- Describe the link destination or purpose when the image functions as a link.
- Avoid keyword stuffing in alt attributes.
- Use crawlable HTML anchor elements.
- Optimize image file size so linked images load quickly.
- Combine image links with contextual text links for important pages.
- Mark paid image links with the appropriate rel attribute.
Accessibility and SEO Go Hand in Hand
Optimizing image links for SEO also improves accessibility. Screen reader users rely on alt text to understand where a linked image will take them. An image link with empty or missing alt text can be confusing or completely unusable. By writing helpful alt text, you serve both users and search engines, which aligns with the broader goal of creating a high-quality website.
Conclusion
Image links do count for SEO. They pass authority, help search engines discover pages, and contribute to relevance signals, primarily through alt text. Whether you are earning image backlinks from infographics and partner logos or using linked images throughout your own website, the key is to provide clear, descriptive context. By combining well-optimized image links with strong text links and solid accessibility practices, you build a link profile that search engines understand and users can navigate with confidence.
