Anchor Text SEO: The 8 Types, the Rules That Matter and an Example of Each

Anchor text is the clickable text of a link, and it is one of the few on-page signals that describes a different page than the one it sits on. Get it descriptive and varied and both users and search engines read your site correctly.

Key Takeaways

• 8 anchor text types cover almost every link you will ever write, from exact match to naked URL.
• Under 10% of a page's inbound links should use exact-match anchor text; over-optimised profiles are the classic footprint of paid link schemes.
• Google's own documentation asks for anchor text that is descriptive, concise and not more than a sentence.
• Internal links are the anchor text you fully control — most sites leave 30-50% of theirs as "click here", "read more" or a bare URL.
• Accessibility guidelines expect link purpose to be clear from the link text alone, which is WCAG 2.2 success criterion 2.4.9.

What anchor text is, and what search engines do with it

Definition: anchor text is the visible, clickable text inside an HTML link element — the words between the opening and closing <a> tag. It tells a user what to expect after the click, and it gives search engines a short human-written label for the linked content. Anchor text applies to internal links inside your own site and to external links pointing at other sites.

The markup is plain HTML: <a href=/blog/seo-keywords>how to choose SEO keywords</a>. The MDN reference for the anchor element is the canonical spec; Google will only follow a link when it is a real <a> tag with an href, which its crawlable links documentation states directly.

Anchor text has mattered to search engines since the earliest link-based ranking work, because the words other people choose to describe your page are independent evidence of what that page is about. The abuse of that signal produced the "Google bomb" era and, eventually, algorithmic filters aimed squarely at manipulated anchor text.

The 8 types of anchor text, with an example of each

Every link you write falls into one of these types. Names vary between tools; the behaviour does not.

Limit 3: 8 types, 1 job — every anchor above exists to label a destination; if a link needs a second sentence to explain itself, the anchor text failed.

Fact 1 — when a link wraps an image, the alt attribute becomes the anchor text, so an image link with no alt text is a link with no label at all.

An anchor text example for every link context

The same target page deserves different anchor text depending on where the link sits. These examples show the pattern.

Rule 1 — if the anchor text still makes sense when read out of context, on its own, it is doing its job. That is the same test the WCAG "link purpose (link only)" criterion applies.

How search engines actually use anchor text

Anchor text does four separate jobs, and confusing them is why so much anchor advice contradicts itself.

Fact 2 — Google publishes 3 link attributes for qualifying outbound links — nofollow, sponsored and ugc — and its outbound link guidance treats all three as hints rather than hard directives. Paid links with keyword-rich anchor text and no qualification are a named violation of the Google Search spam policies.

A healthy anchor text distribution for inbound links

You cannot control what other sites write, but you can measure the profile and spot a footprint. These bands describe what unmanipulated profiles usually look like across a mature site.

Limit 1: when one exact-match phrase accounts for more than 15% of a single page's inbound links, that page is the most likely candidate for a link-based demotion in the site. The Penguin series of updates was built to devalue exactly that pattern, and since 2016 it has run continuously rather than as periodic refreshes.

Internal links: the anchor text you fully control

Internal linking is where anchor text produces the most reliable gains, because every word is yours. Google's SEO starter guide asks for descriptive link text on internal links specifically.

Anchor text works best when the destination page has real substance behind it. If you are still choosing what those destinations should be, start with SEO keyword selection and then check the on-page balance with our keyword density benchmarks.

Writing good anchor text: 9 practical rules

Fact 3 — usability research from the Nielsen Norman Group on writing hyperlinks found users scan link text as a signpost, and vague labels force a wasted click and a back-button return — the cost of "read more" is measured in bounces, not rankings.

Anchor text and accessibility: the overlap is nearly total

Good SEO anchor text and accessible link text are the same instruction, written by two different committees.

The W3C explanation of link purpose in context and WebAIM's link text guidance both recommend the out-of-context reading test, which is the fastest anchor text QA pass any editor can run.

7 anchor text traps that cost traffic

Trap 0 — doing nothing: on the average 300-page site we audit, 4 in 10 internal anchors carry no descriptive words at all.

Anchor text by page type

Rule 8 — 1 pattern per page type. Agreeing these 7 patterns once removes about 90% of anchor decisions from the writing process.

An 8-step anchor text audit

Limit 2: if you can only fix one thing, fix the templates. A single blog listing template with a generic anchor multiplies across every post — often hundreds of low-value links from one line of code.

Tools that report anchor text

Fact 4 — 3 of the 5 tools below are free, so an anchor text audit costs 0 in software and roughly 2 hours of analyst time on a 500-page site.

Google's own links report in Search Console shows the top linking text for your site — the fastest free read on how the web describes you.

FAQ

What is anchor text in SEO?

Anchor text is the clickable words inside a link. Search engines use it as a short description of the linked page, so descriptive anchor text helps them understand what the destination covers and helps users decide whether to click.

Does exact match anchor text still work?

In small quantities, yes. One or two exact-match anchors pointing at a page are normal. Once exact match passes roughly 10-15% of a page's inbound links, the pattern becomes a risk signal rather than a ranking boost.

What is the best anchor text length?

Two to eight words. Google asks for anchor text that is concise and no longer than a sentence, and users scan the first two or three words, so front-load the meaning and drop filler.

Is "click here" bad for SEO?

It carries no ranking penalty, but it wastes the signal and fails accessibility guidance because the link purpose is not clear from the text alone. Replace it with a phrase that names the destination.

What is the anchor text of an image link?

The image's alt attribute. If a linked image has no alt text, the link has no label for search engines or screen readers, so every linked image needs a descriptive alt of at least a few words.
