SEO Tools Comparisons 2026
SEO tools look alike on the surface - track keywords, audit your site, find backlinks - but they differ sharply on the numbers that move the decision: how deep the backlink or keyword index really is, what the free or trial option actually gives you, how the bill scales (by credit pool, tracked keywords, site count or user seat), and what the AI-visibility add-on tracks in 2026. This page collects every head-to-head we have run across Ahrefs, Semrush, Moz, Screpy and SpyFu so you can jump straight to the matchup you care about. Prices come from each vendor's live pricing page and were re-checked on the date shown, because Ahrefs' 2026 price increase and the AI-search add-on push at Semrush and Moz change the comparison fast enough that we verify rather than guess.
