Ahrefs alternatives
The highest-scoring alternative to Ahrefs is Hasdata at 58/100 on the AgentReady, against 83/100 for Ahrefs.
All scored in SEO & Search Intelligence.
What Hasdata does that Ahrefs does not
Hasdata passes llms-full.txt / full agent docs, cli available, and Ahrefs fails them. That is the whole of the gap between the two scores, so if none of those matter to your agent the ranking above overstates the difference.
Why people look for an alternative
Ahrefs fails llms-full.txt / full agent docs, authentication documented, fast time to first request, copyable quickstart, cli available, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.
Where Ahrefs loses the points
| Pillar | Ahrefs | What it measures |
|---|---|---|
| Discover | 93 | Can an agent find it at all: sitemap, robots, structured data. |
| Understand | 92 | Is there a spec, an llms.txt, a machine-readable description. |
| Adopt | 85 | Signup, keys, SDKs, and whether a human has to be involved. |
| Operate | 61 | Rate-limit headers, errors, status, and behaviour under load. |
Ahrefs is weakest on operate at 61/100. Missing rate-limit headers mean an agent finds the limit by hitting it. If that is the part your agent depends on, take the ranking above seriously; if it is not, Ahrefs may still be the right pick.
What an agent runs into with Ahrefs
These are the findings from the last audit on 2026-08-22. Each one is a place unattended software stops, which is the practical reason to look at the list above.
- Return X-RateLimit / Retry-After headers so agents pace themselves.
- Publish an AGENTS.md or llms-full.txt with full agent context.
- Add a copyable quickstart so first success is fast.
- Ship a CLI; it is an easy agent adoption path.
- Support an Idempotency-Key so retries are safe.
