FAQ
How much do SEO tools cost in 2026?
Verified on official pricing pages (2026-11-01), cheapest paid plan billed monthly: KeySearch Starter $24, Ahrefs Starter $29, Ubersuggest Individual $29, SpyFu Basic $39, Ranktracker Launch $39, Moz Pro Starter $49, Mangools Basic $61, Serpstat Team $129, SE Ranking Core $129 and Semrush SEO $139.95. Raven Tools (from $39/mo) and SEO PowerSuite (from $349/yr) only publish yearly prices; Serpstat Individual ($50/mo) is annual-only.
Why does the calculator rank tools differently from their sticker price?
Plans cap different things: Semrush and Ahrefs charge per extra user ($45+ and $40–$100/mo), Ahrefs Starter has no rank tracking, Ubersuggest and SpyFu limit tracked keywords per project or update weekly, Serpstat and Raven meter position checks per month, Mangools Basic allows one user. We test your sites, keywords, users and update frequency against every published limit and keep the cheapest plan that covers you.
What is the cheapest SEO tool for an agency?
For 10 sites, 1,500 keywords tracked daily and 3 users, billed annually: Ubersuggest $54.75/mo (Enterprise), Serpstat $100/mo (Team), Ranktracker $119.20/mo (Scale), SE Ranking $223.20/mo (Growth). Check white-label reports and client seats on each tool page.
Which SEO tools have a free plan?
Semrush Free (1 demo project, 10 reports a day), Ahrefs Free (limited Site Explorer and Site Audit for your own sites), a Mangools free account (limited lookups) and the SEO PowerSuite free desktop license (with limits). Trials: Semrush and Ubersuggest 7 days, Serpstat 7 days, SE Ranking 14 days. Ahrefs offers no trial.
What does “Not listed” mean?
The official pricing page does not publish that number — for example SE Ranking’s extra seat price, KeySearch annual prices, Raven Tools monthly prices or Ahrefs’ rank update frequency. We never estimate it: the calculator shows the tool as not computable for that shape and says why.
Are these affiliate links?
Visit buttons route through /go/ links marked nofollow sponsored. Rankings come from the cost engine and published limits only; commissions never change a price cell.
