Part of How should a buyer score the evidence behind SEO tool claims?
9 checks before buying SEO tools licences and data
A nine-point checklist for SEO tool buyers: verify licences, seat maths, data sources, compliance, contracts and renewal dates before you sign.
What to take away
- The nine checks below cover licences, data sources, compliance and renewal terms. Run them before you sign.
- Give each check an owner and a test you can run during a trial.
- Model the licence unit, seat maths and exit terms. They drive cost more than the headline price.
- Record which data sources you verified and which the vendor would not confirm.
- Set a mid-term review and a renewal decision at purchase.
The 9 checks
- Define the job before any demo. Write down the decisions the tool supports, who acts on the output and how often. A tool that produces unused reports fails, whatever its feature grid says. Agree pass or fail criteria with daily users first.
Example for check 1: pass if the weekly content team changes at least two briefs a month from the report, and fail if no one opens it after week four.
9 Checks Before You Buy
- Define the job before any demo
- Fix scoring weights before demo
- Verify data sources and coverage
- Confirm licence unit and seat maths
- Check compliance and data rights
- Review contract terms and exit clauses
- Note renewal dates and price rises
- Agree pass or fail criteria first
- Fix scoring weights before you see a demo. Grade evidence, not presentation. A documented data source outranks a confident walkthrough. Our review methodology for data and sources explains how to grade vendor evidence and record an undisclosed source.
- Verify data sources and coverage. Ask where keyword, ranking and traffic figures come from. Semrush's keyword research features is one example of how a vendor describes coverage, and each claim is testable.
Compare Ahrefs, Moz and Similarweb on inputs. Ahrefs runs its own crawler for backlinks and organic data, while Moz Pro uses Link Explorer and Domain Authority.
Similarweb blends panel and clickstream estimates and often charges custom pricing, while Google Search Console is free but limited to verified sites and keeps 16 months of query data. Run ten queries you already rank for, in your target languages, and note gaps.
Record each source in a two-column register: source name and status (verified or unverified), with the date checked.
- Confirm the licence unit and seat maths. Establish whether one licence means a user, a domain, a project or a monthly keyword quota. Semrush tiers plans by projects and tracked keywords, with extra user seats charged. Ahrefs tiers by credits and users, and extra seats cost more. Moz Pro tiers by campaigns and tracked keywords. Model a three-person team and a contractor. Write the unit next to the price.
- Map contract length, notice and exit. Check notice periods, auto-renewal and what happens to historical data on exit. Ask how rankings and reports export, and in what format. A twelve-month term with a thirty-day notice window commits you differently from a rolling monthly plan. Ahrefs and Semrush both list monthly and annual billing, so compare the commitment. Confirm export formats before you rely on portability.
- Check compliance and ad claims. If your marketing includes paid search alongside organic work, the CAP advertising codes set the rules for UK ad copy and landing pages. Check whether the tool helps or hinders that, for example by generating claim-heavy page templates. Confirm data protection terms before loading client data. The Information Commissioner's Office enforces UK GDPR and can fine firms for poor handling.
- Check public sector routes. If you sell to public bodies, procurement often runs through frameworks. The G-Cloud supplier guidance on GOV.UK, now marked withdrawn, set out how vendors applied. One current route is Crown Commercial Service's G-Cloud 14 (RM1557.14), which lists cloud software and related services. Listing rules can shape which tools you buy and resell.
- Run a worked cost example. A three-person team paying £95 per seat each month spends £285 a month, or £3,420 a year. A keyword module at £40 per seat takes the annual figure to £4,860. A second tracking tool at £60 a month takes the running total to £5,580. These are illustrative; use your own quotes.
All figures are in pounds sterling and exclude VAT.
- Set review and renewal dates. Add a mid-term review and a renewal decision. Re-run the tests at each point, because pricing and coverage both move. The pillar guide on reviews and comparison methods for 2027 explains how to keep comparisons consistent between rounds.

Common questions
How do we test the job during a trial?
Pick one recurring decision the tool should support, name the owner, and check during the trial whether that decision changed. If the decision did not change, the job is not proven.
What if a vendor will not disclose a data source?
Record the gap and score the line as unverified rather than failing it outright. If two suppliers are otherwise level, the one that discloses more usually wins.
When should the checklist be re-run?
At the mid-term review and again before renewal, and any time the licence unit or your headcount changes.
