Images can do more than add color to a webpage. When an image links to another page, its linked image anchor text helps people and search engines understand where that link leads. A thoughtful choice can make a site easier to navigate and support its search visibility; a careless one can leave visitors guessing.
Unlike a text link, an image link has no visible words to describe its destination. The image’s alternative text, or alt text, usually serves that role for screen readers and can also provide search engines with context. That makes the wording worth considering as part of both content design and technical SEO.
What anchor text does for an image link
Anchor text is the wording associated with a clickable link. In a standard text link, readers see the words directly. With an image link, the description is generally supplied through the image’s alt attribute. For example, a button image linking to a pricing page could use alt text such as “View service pricing.” The phrase communicates the action and destination more clearly than a generic label like “button.”
Good descriptions can help visitors using assistive technology understand what will happen when they select an image. They can also give search engines useful information about the linked page. For a deeper explanation of how anchor text influences SEO, it helps to consider the same principles that apply to ordinary text links: relevance, clarity, and restraint.
Write for the person using the page
The first test is simple: if someone could not see the image, would the description still tell them what the link does? Focus on the function of the image, not just its appearance. “Open the course catalog” is more helpful for a linked graphic than “blue book icon,” if selecting it opens a catalog.
Keep descriptions concise, but include enough information to distinguish the link from nearby options. If a page has several linked product images, describing each only as “product photo” offers little help. A short, specific phrase such as “See the oak desk details” gives the user a better idea of the next step.
Context matters, too. If visible text beside an image already explains the link, repeating that exact wording in the alt text may create a tedious experience for screen-reader users. Depending on the page structure, the image may be decorative and need empty alt text, or it may add important information that should be described. The goal is not to add keywords everywhere; it is to make the link understandable.
SEO value without over-optimisation
Relevant anchor wording can help search engines interpret the relationship between the source page and the destination. But an image description is not a shortcut to rankings. Search engines consider many signals, and repetitive keyword phrases can make a site look manipulative rather than useful.
Use words that accurately describe the destination or action. If a graphic links to a guide about budgeting, wording such as “Read the monthly budgeting guide” is clearer than forcing in a string of unrelated search terms. Avoid using the same exact-match phrase for every image link, especially when the links point to different pages. Natural variation is appropriate when it reflects real differences in the content.
Also separate image alt text from captions and nearby page copy. Alt text is intended to describe an image’s meaning or function when the image cannot be perceived. It should not become a hidden place to pack extra keywords or repeat every detail already written on the page.
A practical review before publishing
- Check the destination: Confirm that the linked page matches what the image description promises.
- Describe the action: Use wording that explains what selecting the image will do.
- Keep it specific: Distinguish similar links with relevant names, products, or page types.
- Remove clutter: Skip phrases such as “image of” when they add no useful meaning.
- Test the experience: Review the page with images turned off or use a screen reader to check whether links remain understandable.
A content audit can catch issues that are easy to overlook during routine publishing, particularly on sites with many product cards, banners, or image-based calls to action. A small sample review can reveal patterns: repeated generic alt text, links with unclear destinations, or images that are decorative but announced unnecessarily.
When to bring in outside help
Small teams may be able to manage image descriptions as part of their normal editorial workflow. A larger redesign or a site with hundreds of pages may call for a developer, accessibility specialist, or SEO professional. The right choice depends on the task: a one-time audit, ongoing technical work, or broader marketing support require different skills and budgets.
For a project like this, it can be useful to compare a solo specialist with a larger provider. Osdire’s guide to freelancers, agencies, and agency account management outlines factors such as scope, cost, and communication that can help a business decide what level of support fits. Before hiring, define the deliverables—for example, an audit of image links, revised descriptions, and a handoff process for future content.
Conclusion
Linked image anchor text works best when it is clear, accurate, and written for the person navigating the page. Describe what the link does, avoid repetitive keyword targeting, and make sure each image’s role is clear in context. Those habits improve accessibility while giving search engines a more useful signal about your site’s content. A few careful checks can turn image links from vague visual shortcuts into reliable parts of the user experience.
