About Ahrefs

Ahrefs runs one of the largest web crawlers in existence, and its backlink index is the reason most SEOs keep a subscription: Site Explorer shows who links to any site, with keyword research, rank tracking, and site audits built on the same data. Brand Radar extends that to AI search, tracking brand mentions in ChatGPT, Perplexity, Gemini, and Google AI Overviews. Free Webmaster Tools cover your own verified sites; paid plans run from the $29/month Starter to Lite at $129/month ($108/month billed annually). There is no free trial, and famously no affiliate program.

Pros

Backlink data quality that competitors are measured against
Free Webmaster Tools give real audit and backlink data for your own sites
$29/mo Starter is the cheapest entry into serious SEO data
Fast, no-nonsense UI that experienced SEOs prefer to Semrush's sprawl

Cons

Credit system on lower tiers is widely hated — 1.8 on Trustpilot, with users reporting burned allowances and account flags
No free trial, and key AI features (Brand Radar, AI Content Helper) are paid add-ons on top of plans
Extra seats cost $40-$80/mo each depending on plan
Narrower than Semrush — no PPC, social, or content-marketing toolkit

Our verdict

Best for: SEOs and link builders who want the most trusted backlink data and are comfortable with a usage-metered toolset.

Skip if: You want an all-in-one marketing suite or predictable unlimited usage at the entry tiers.

Our review

Ahrefs is the tool SEOs describe with a possessive — 'my Ahrefs data' — because for link intelligence it remains the reference point. The crawler's freshness and index size make Site Explorer the first tab opened in most link audits, and the surrounding toolkit (Keyword Explorer, Rank Tracker, Site Audit) inherits that data quality. The free Webmaster Tools tier is genuinely useful, and the $29 Starter is the cheapest legitimate entry into professional-grade SEO data anywhere.

The resentment in its reviews is equally earned. The credit system on lower tiers turned a beloved flat-rate tool into a metered one — Trustpilot's 1.8 is full of users who burned a month of Starter credits in an hour — and the AI-era features that Semrush bundles into mainline plans are add-ons here: Brand Radar and the AI Content Helper both cost extra on top of your subscription. Value for money is now the weakest part of the offer.

One more thing buyers should know: Ahrefs famously runs no affiliate program, which means the wall of glowing Ahrefs reviews online is largely unpaid — rare in this category, and quietly a point in its favor.

Verdict: still the best backlink tool money can buy, and the default second subscription for anyone serious about links. Just read the credit terms before picking a tier, and budget for the add-ons if AI-search tracking matters to you.

What reviewers elsewhere say

72% positive — Backlink and keyword data quality is near-universally praised; the credit system, account restrictions, and add-on pricing draw intense criticism.

Can Ahrefs track my brand in ChatGPT and AI Overviews?

Yes, through Brand Radar — a paid add-on that tracks brand mentions and share of voice across ChatGPT, Perplexity, Gemini, and Google AI Overviews using Ahrefs' prompt dataset.

Why is Ahrefs rated 1.8 on Trustpilot but 4.5 on G2?

G2 reviewers rate the product's data quality; Trustpilot complaints cluster around the credit system introduced on lower tiers, surprise allowance burn, and account restrictions. The data is excellent — the metering is what people resent.

Ahrefs or Semrush?

Ahrefs for backlink depth, crawler freshness, and a leaner UI; Semrush for breadth — PPC, content tools, and AI visibility tracking included in mainline plans. Many agencies justify paying for both.
