SEO tools
An SEO tool is software that estimates search demand, maps backlinks, tracks rankings and audits sites for technical faults. Our SEO tools reviews compare eight of them on the plan you would actually need, the limit you will hit first (keywords, seats or AI prompts) and what you pay at renewal, using prices listed in October 2026.

What does an SEO tool do that Google won’t?
An SEO tool shows you other people’s data. Google Search Console covers your own site for free, but only a paid suite reveals competitors’ keywords, the backlinks pointing at their pages and the searches you don’t rank for yet, which is the half of SEO research Google keeps to itself.
The big suites bundle five jobs into one login: keyword research, backlink analysis, daily rank tracking, site audits and, newest of all, tracking how ChatGPT, Gemini and Google’s AI answers mention your brand. Specialists go deeper. Screaming Frog crawls. Surfer grades drafts against pages that already rank, and if you’ve already paid for a full suite, you rarely need either.
Which SEO tool fits you?
Pick by the limit you will hit first. In practice that limit is tracked keywords or seats, and those two numbers decide whether Semrush, SE Ranking or a budget tool such as Mangools costs less once you add up a full year of billing.
- If one marketing team needs one login: Semrush. Its Starter plan ($199) tracks 50 AI prompts a day across ChatGPT, Gemini and Google AI Mode. Extra seats start at $45.
- If you track rankings for clients: SE Ranking, because Core tracks 2,000 keywords daily across 10 projects for $129, four times Semrush’s entry limit, and white-label reporting adds $69 a month on top.
- If links are the job: Ahrefs. Budget for Standard at $249, the plan our research treats as realistic for regular link work.
- If you run one blog: Mangools. It starts at $29. Refunds are full within 48 hours.
- If you fix crawl problems: Screaming Frog, free up to 500 URLs, then $279 per user per year.
- If you only write content: Surfer, from $49 billed yearly. Don’t use it as a suite; it has no backlink index.
| Tool | Headline price | Plan most buyers end up on |
|---|---|---|
| Semrush | $139/mo SEO plan ($117.33 yearly) | Starter at $199/mo for AI prompt tracking |
| SE Ranking | $129/mo Core ($103.20 yearly) | Core, plus $69/mo white label for agencies |
| Ahrefs | $29/mo Starter | Standard at $249/mo |
When should you not pay for an SEO tool at all?
Skip the subscription when you run one small site and don’t study competitors. Google Search Console shows the real queries, clicks, impressions and indexing errors for your pages. No paid tool sees that first-party data.
Add Screaming Frog’s free tier and a free Moz account (10 keyword and 10 link lookups a month). Google’s SEO Starter Guide costs nothing either, and it says plainly that no secret will rank a site first. Don’t bother with a suite until you manage several sites, report to clients or fight for a crowded market, because before that point $1,408 a year for Semrush’s SEO plan is hard to justify.
What catches SEO tool buyers out?
Seats, add-ons and refunds. All three sat below the headline price on the pricing pages we checked in October 2026.
- Seats. Most plans include one user. Semrush charges up to $100 monthly per extra user, while SE Ranking starts at $16 and Serpstat’s Team plan bundles three users for $100.
- Add-ons. AI-search tracking costs $199 extra at Ahrefs (Brand Radar AI). At Moz it starts on the $179 Medium plan.
- Refunds. SE Ranking payments are non-refundable and Ahrefs refunds only unused monthly plans, so run SE Ranking’s 14-day no-card trial before you hand over a card.
Most people miss the plan migrations. Semrush replaced Pro, Guru and Business in July 2026, and the old Guru tier rose from $208.33 to $248.17 a month on annual billing. Check your limits when you renew. And don’t trust database totals such as Ahrefs’ 35 trillion backlink records; nobody audits them.
How we build our SEO tools reviews
Our SEO tools reviews are research scores, not lab results. We read official pricing pages, plan limits, documentation, refund terms and independent roundups, then score every tool on the five weighted criteria below. We don’t run crawl or rank-tracking tests.
Read a score as a fit signal. When you see two tools on the same number, as with Semrush and SE Ranking at 8.7, the order comes from the unrounded score (8.74 against 8.735), so treat them as equals and decide on seats and limits. A 7.5 for Screaming Frog means it does one job, not that it does it badly. Commissions never move a score; Ahrefs and Screaming Frog pay none. Related tools sit under marketing and SEO.

Questions people ask
Are free SEO tools good enough?
For one small site, often yes. Google Search Console shows your real clicks, impressions and indexing problems at no cost. Screaming Frog crawls up to 500 URLs free, and a free Moz account gives 10 keyword and 10 link queries a month. When you start comparing yourself with competitors, paid suites add what free tools lack: their keywords, your keyword gaps and backlink data for any domain.
How much does an SEO tool cost per month?
Budget tools start at $29 a month (Mangools Entry, Ahrefs Starter). Full suites cost more: $139 month to month for Semrush's SEO plan, $129 for SE Ranking Core and $249 for Ahrefs Standard. Annual billing saves 17% to 40%. None of the eight advertises an intro discount, so the price you see is the price you renew at. Skip the monthly plan once you know you will stay a year.
Which SEO tool is best for beginners?
Moz Pro is the cheapest full suite from an established brand at $49 a month, with audits, link research and the Domain Authority metric clients already quote. Its Starter plan tracks only 50 keywords. Mangools suits bloggers at $29, its keyword difficulty score is easy to read, and if you change your mind within 48 hours you get a full refund. Set up Search Console first. Always.
Are the backlink and keyword counts SEO tools advertise accurate?
Treat them as claims. Ahrefs advertises 35 trillion backlink records refreshed every 15 to 30 minutes, Semrush 43 trillion backlinks plus 28 billion keywords in 142 country databases, and Mangools 9.5 trillion, but no independent body audits these totals and each vendor counts something different. Don't trust totals as a ranking of tools. Compare them on the data they return for your own market and competitors.
Can SEO tools track rankings in ChatGPT and AI Overviews?
Yes, at a price. Semrush tracks 50 AI prompts a day on Starter ($199), SE Ranking Core includes 100, Ahrefs sells Brand Radar AI from $199 a month and Surfer Pro covers five AI engines. Treat the output as a sample of how assistants mention you when someone asks a tracked question, not as traffic data: the reports count mentions, not the visits that follow.
