What a good SEO tool actually has to do
Most free SEO tools return a score and leave you to work out what it means. That is the easy half. The useful half is telling you which specific thing to change first, and what it is worth changing it for — a number without a next step is trivia.
The tools here are built the other way round. Each one answers a single question with a concrete output: which keywords you could realistically win, what a competitor covers that you do not, how a page would look in the search results, whether a draft is likely to rank.
Choosing between the best SEO software for small businesses
The buying question for a small business is rarely which tool has the most features. It is which one you will still be using in three months. Enterprise SEO platforms are priced and shaped for a team with someone whose job is SEO; if nobody at your company has that job, the features go unused and the subscription gets cancelled.
Two things worth weighing: whether the tool produces work or only produces reports, and whether it fits the language and market you actually sell in. Most of the best-known platforms are built US-first, which shows up in thin keyword data for Dutch, German and French markets.
Free tools, and what sits behind them
Everything on this page runs without an account. They are genuinely useful on their own, and they are also the visible edge of what BoltSEO does automatically — the same keyword research, competitor gap analysis and on-page checks, run on a schedule and turned into published articles rather than a report you act on later.
If the free tools tell you what to fix, the platform is what fixes it while you run the business.
