Example prompt: Can you pull the top 50 anchor text phrases used in backlinks pointing to ahrefs.com? I want to see what keywords people are using when they link to them.

## When to prefer this

Use this endpoint when you need to audit or analyze the anchor text distribution of a domain's backlink profile — particularly for SEO audits, penalty investigations, competitor link strategy research, or verifying anchor text diversity. Prefer this over general backlink profile endpoints when the specific text used in links (not just link counts or sources) is what matters.

## Known failure modes

- Invalid or non-existent domain returns an error or empty result
- Limit parameter outside 1–100 range is rejected with a validation error
- Domain with very few backlinks may return fewer anchors than requested
- Scheme or path included in target may be stripped silently or cause a parse error
- Network timeout or upstream data provider unavailability returns 5xx

## How this service works

Backlink anchor text API - list the anchor texts pointing at a domain, each with how many backlinks, referring domains and referring pages use it, the dofollow/nofollow split, DataForSEO rank, spam score and broken-link count. For anchor-text distribution analysis, over-optimization/penalty audits and link-building research. Unknown domain returns empty results.

## Output

A ranked list of anchor text strings used in inbound links to the target domain, up to the specified limit (default 20, max 100), likely including each anchor phrase and its frequency or share of total backlinks.
