A partial match anchor is a link whose clickable text contains the target page’s main keyword alongside other words, or a close variation of that keyword, rather than the keyword on its own. If a page targets “boiler repair”, a link reading “same-day boiler repair across south London” is a partial match; a link reading only “boiler repair” is an exact match anchor.
How partial match anchors work
Search engines read the words in a link as a clue to what the destination page is about. That is the whole point of anchor text: it describes the page before anyone lands on it. A partial match anchor gives that clue while still reading like ordinary English, because the keyword sits inside a longer phrase that a writer would naturally use.
Partial match anchors take a few common shapes:
- Keyword plus modifier: “accountants for contractors in Leeds” pointing to a page about contractor accounting.
- Reordered or inflected keyword: “repairing a leaking flat roof” pointing to a flat roof repair page.
- Keyword inside a sentence fragment: “this guide to VAT registration thresholds” pointing to a VAT registration page.
- Synonym or close variant: “conveyancing solicitor” pointing to a page optimised for “property solicitor”.
Google does not publish a definition of these categories. They are labels the SEO industry uses to describe and audit link profiles, and tools such as Ahrefs or Semrush classify anchors in slightly different ways, so treat any percentage you see in a report as an approximation.
Why it matters for a UK business
Anchor text is one of the more visible signs of whether links were earned or arranged. When a journalist at a regional paper, a trade association or a supplier links to you, they tend to use your business name, your web address or a loose description. When links are bought or swapped, the anchors are often suspiciously keyword-heavy. Google’s 2012 Penguin update was aimed squarely at that pattern, and Google’s spam policies still list links with optimised anchor text in schemes as a violation.
Partial match anchors sit in the middle ground. A healthy profile usually has some, because people describing your work will mention what you do. They become a problem when the same commercial phrase with a town name bolted on appears again and again across unrelated sites. A Manchester plumber whose backlinks mostly read “emergency plumber Manchester 24/7” in slightly different orders has a profile that looks engineered, even if no single link is an exact match.
They matter on your own site too. Internal links are fully under your control, and Google’s own documentation encourages descriptive anchor text for them. A link from a blog post reading “how I price a commercial EPC survey” tells both readers and search engines far more than “see our services”.
Common mistakes
- Swapping exact match anchors for partial match ones and assuming that solves an over-optimised profile. The pattern of repetition is what stands out, not the exact wording.
- Asking guest post hosts or directories for a specific keyword-rich anchor every time.
- Writing internal links that cram three keywords into one phrase, which reads badly and helps nobody.
- Ignoring anchors altogether and using “here” or the bare URL for every internal link, which wastes the clearest signal you control.
- Panicking over a handful of keyword-rich links that arrived naturally. Context and proportion matter more than any single anchor.
How to act on it
Export your backlinks from Google Search Console or a third-party tool and group the anchors into branded, URL, generic, exact and partial match. Look at the anchor text distribution as a whole, then read the links behind any phrase that repeats unusually often. If the repeats come from low-quality sites you or a previous agency paid for, the priority is stopping that activity; a disavow file is only worth considering where a pattern of manipulative links is large and deliberate.
For new links, focus on being worth citing and let the linking site choose its own words. Where you do have influence, such as a partner’s case study or a local business association listing, a natural description that includes what you do is fine. On your own pages, write internal links whose anchors describe the destination in plain language, and vary them the way a person would.
