Independent SEO practitioners, mostly in r/bigseo, broadly treat Ahrefs as the benchmark for backlink data and link auditing, and several say it is the one paid suite they kept when consolidating tools. The main trade-offs are cost, traffic and keyword estimates that users call directional at best, and newer pieces that lag: rank tracking and Site Explorer suffered after Google's num=100 change, and some who tried Brand Radar preferred rivals. About one in seven comments were promotional, including five replies from Ahrefs staff in a feedback thread the company hosted and several plugs for other products; these were excluded.
Users like
- Backlink data is widely seen as the strongest of the major suites; users who keep Semrush or SE Ranking for other work still turn to Ahrefs for link analysis[1][2][3][4][5][6][7]
- Useful for catching spam and toxic links: users report spotting a link farm pointed at their site and disavowing it, and filtering out junk domains[1][2][3][4]
- Broad enough to be the one paid suite: users who cut their tool spend kept Ahrefs plus a crawler such as Screaming Frog, and long-time users prefer it for medium to large SEO projects[1][2][3][4]
- Site Audit is rated well, including by a user running Ahrefs and Semrush side by side, though users say it does not replace Screaming Frog[1][2][3]
Users complain about
- Expensive: users call the price high, have switched to SE Ranking to save money without missing much, or stay on cheaper tools until they have the budget[1][2][3]
- Traffic and organic keyword estimates can be far off, especially for small or low-authority sites, and one user says they have become less reliable after recent core updates[1][2][3][4]
- Slow to recover from Google's num=100 change: with keyword tracking still unfixed after weeks, one user was cancelling and another saw it as a sign of low priority, and a team says Site Explorer never fully recovered[1][2][3]
- Brand Radar, its AI visibility tracker, gets a weak reception: one enterprise user found its data looked like rehashed keyword data and chose Peec.ai, another rates Semrush's equivalent higher, and a third found it too expensive to test[1][2][3]
Independent users, mostly in r/bigseo and r/SEO, treat Semrush as a capable all-in-one SEO suite whose strongest area is keyword research, and several run keyword work, audits and competitor research from it. The main trade-off is backlinks and cost: most comparisons say Ahrefs (or Majestic) has the better link index, a recurring view is that it costs more than the share of features people actually use, and users warn its search-volume and traffic numbers are directional estimates, with keywords it shows at zero volume still driving clicks. About a quarter of the comments were promotional, including cheap shared-account group-buy offers, agency pitches and a cluster of near-identical comparison replies.
Users like
- Keyword research is the most-praised area: users call it the best keyword tool after Google and say it is strong for keyword work and keyword clustering, even when they use Ahrefs for links[1][2][3][4]
- Covers several jobs in one place: users run keyword research, site audits, competitor analysis, SEO content briefs and toxic-backlink monitoring with alerts and disavow from it[1][2][3]
- One user who runs every project on it finds its organic keyword data closely matches Google Search Console, and prefers how it weights nofollow comment links over Ahrefs[1]
Users complain about
- Backlink data trails Ahrefs and Majestic: users describe the link index as noisy, especially for lost links, say its crawler still needs work, and switch to Ahrefs for link-related tasks[1][2][3][4][5]
- Seen as expensive for what many users actually use: comments call it a great tool but not worth the cost, no longer valuable, or bloated, and some consolidated onto other tools to cut spend[1][2][3][4][5]
- Search-volume and traffic figures are estimates: keywords it reports at zero volume show 10 to 100 searches in Search Console or bring 150 to 250 clicks a month, and users say traffic estimates across these tools can be far off[1][2][3][4][5]
- Some buyers hesitate over its future because of the Adobe acquisition[1][2]
