  • They diverge on capability: Ahrefs covers Site Explorer, SimilarWeb covers Traffic analytics.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Ahrefs

  • The April 2024 move from unlimited usage to credits was a real downgrade for existing customers: Lite meters 1,000 credits per user per month and the data tools lock when they are gone, so heavy research on the entry plan now forces an upgrade to Standard at 249 USD.
  • Pay-as-you-go credits are charged automatically once enabled, so a busy research month can produce an unbudgeted overage bill rather than a hard stop.
  • Every paid tier includes exactly one user, and additional seats cost 40, 60 or 80 USD a month by tier, so a three-person team on Standard pays 369 USD a month rather than 249.
  • Row caps bind before credit caps for many jobs: Lite returns at most 2,500 rows per report, which is not enough to export a mid-sized site backlink profile in one pass.
  • Ahrefs states plainly that it never runs discounts and offers no free trial of the paid plans, so evaluation means paying a full month or working from the ownership-verified free tier.
  • Rank Tracker updates weekly on every tier including Enterprise, so teams needing daily positions have to buy a separate tracker such as SE Ranking or Semrush.
  • A growing share of capability is sold as add-ons rather than included: Report Builder at 99 USD a month, Content Kit from 99 USD, Project Boost at 20 or 200 USD per project, and Brand Radar from 199 USD.
