Anchor text is the clickable, visible text within a hyperlink. When you see a blue underlined word or phrase on a webpage, that's the anchor text. It acts as the label for a link, telling both users and search engines what to expect on the other side.

Quick definition: Anchor text is the human-readable part of a hyperlink — the words you can click. In HTML it looks like this: <a href="url">This is the anchor text</a>

Why Does Anchor Text Matter for SEO?

Google's algorithm uses anchor text as a contextual relevance signal. When many websites link to a page using the anchor text "best running shoes," Google interprets that as a strong indicator that the linked page is about running shoes. This is why anchor text has historically been a powerful ranking factor.

However, over-optimising anchor text — particularly with exact-match keywords — can trigger Google's spam filters and result in manual or algorithmic penalties. A natural, varied anchor text profile is what you should aim for.

Types of Anchor Text

Not all anchor text is created equal. Here are the main types SEOs work with:

  • Exact Match — The anchor text exactly matches the target keyword (e.g., "link building strategies"). Powerful, but risky in large quantities.
  • Partial Match — Contains the keyword alongside other words (e.g., "these link building strategies work well"). More natural-looking.
  • Branded — Uses a brand name (e.g., "Ahrefs" or "SEO is Alive"). Considered the most natural type.
  • Generic — Non-descriptive phrases like "click here," "read more," or "this article." Minimal SEO value but fine in moderation.
  • Naked URL — The raw URL is used as the anchor (e.g., seoisalive.com). Common in citations and directories.
  • Image Alt Text — When an image is linked, Google uses its alt attribute as the anchor text.

What Makes a Healthy Anchor Text Profile?

A natural backlink profile has a mix of all anchor text types. Most links from real websites use branded or generic anchors simply because that's how people write naturally. A profile dominated by exact-match anchors looks manipulated and can attract algorithmic scrutiny.

Good rule of thumb: If you're building links, aim for 60–70% branded/generic anchors, 20–25% partial match, and no more than 5–10% exact match.

Internal vs. External Anchor Text

Anchor text applies to both internal links (links within your own site) and external links (links from other sites). For internal linking, you have full control and should use descriptive, keyword-relevant anchor text to help Google understand your site's structure. For external links, you can suggest anchor text to link partners, but cannot force it.

Key Takeaways

  • Anchor text tells search engines what the linked page is about.
  • A diverse, natural anchor text profile is safest for long-term SEO.
  • Exact-match anchors have SEO power but should be used sparingly.
  • Internal links give you full control — use descriptive anchors.
