Anchor Text - Definition, Types, and Best Practices

Why Anchor Text Matters

Anchor text is one of Google's oldest and most direct relevance signals. The original PageRank patent treated anchor text as a label describing the destination URL. Today, over-optimised anchor text (too many exact-match keywords pointing to the same page) is a primary trigger for the Penguin algorithmic filter, which is why a natural mix of anchor types is critical to a healthy off-page SEO profile.

How Anchor Text Works

When Googlebot crawls a page, it records every outbound link along with its anchor text and stores both in the link graph. The anchor text becomes a signal of what the destination page is about, weighted by the linking page's authority and topical relevance. A page with the anchor text 'best running shoes' pointing at it from many different domains will be more strongly associated with that query.

Internal anchor text works the same way and is fully under your control. Choosing descriptive internal anchors (not just 'click here') is one of the cheapest on-page wins in SEO.

Types of Anchor Text

✓Exact match: the linked page's primary keyword verbatim

✓Partial match: includes the keyword plus other words

✓Branded: your brand or domain name

✓Naked URL: the raw URL displayed as the anchor

✓Generic: 'click here', 'read more', 'this article'

✓Image: alt text on a linked image becomes the anchor

✓Long-tail: a full descriptive phrase or question

Anchor Text Best Practices

Keep exact-match anchors below ~5-10% of your inbound anchor profile

Mix branded, partial-match, and descriptive anchors for natural diversity

Use descriptive internal anchor text instead of 'click here' or 'read more'

Avoid stuffing the same keyword across every internal link to one page

Audit inbound anchor profiles quarterly using Ahrefs or Semrush

Disavow links with toxic or unrelated anchor text via Google Search Console

On image links, write descriptive alt text since alt becomes the anchor

Frequently Asked Questions

What is the best anchor text for SEO?

There is no single best anchor. Google rewards a natural mix: branded anchors, partial-match phrases, descriptive long anchors, and the occasional exact match. Over-using any one type, especially exact-match keywords, is the fastest way to trigger an algorithmic penalty.

Does internal anchor text matter?

Yes, significantly. Internal anchors are entirely under your control and tell Google what each linked page is about. Descriptive internal anchor text often produces more relevance lift per hour of work than external link building.

What is over-optimised anchor text?

Over-optimisation happens when an unnatural share of inbound or internal anchors uses the exact target keyword. Google's Penguin algorithm flags this pattern and can suppress rankings for the affected page. Aim for a varied, intent-led anchor profile instead.
