15 Free SEO Tools Every Small Business Should Use

The dirty secret of SEO software: a small business can run a genuinely professional SEO operation on free SEO tools — $0, total — because Google gives away the most important data itself. Paid suites earn their keep at agency scale; for one site, the free stack below covers seeing what Google sees, finding keywords, fixing speed, and tracking results. Fifteen tools, grouped by the job they do, with the honest limits of each.

The two you set up before everything else

Search Console is the only place Google tells you directly which queries show your site, where you rank, and what’s broken — five minutes to verify, and every other SEO decision improves the moment it’s collecting. GA4 answers the other half: what visitors did after arriving. Together they replace the reporting module of any paid suite for a single site. If you set up nothing else this month, set up these two — they’re also the first thing we set up on every client site we touch, and the reason the SEO timeline can be judged with evidence instead of vibes.

Keywords without the $99/month subscription

Keyword Planner gives volume ranges (create the Ads account, skip the campaign). Trends shows direction and seasonality — invaluable for content calendars. And the results page itself is the most honest keyword tool ever shipped: autocomplete completes with what people actually type, People-Also-Ask lists the questions worth a FAQ block each. That trio, plus an hour, produces the keyword map most small sites need — the method behind every FAQ section on this blog.

Technical checks that used to cost audits

PageSpeed Insights scores your Core Web Vitals from real-user data; Lighthouse (right-click → Inspect → Lighthouse, in Chrome already) audits any page in a minute; Screaming Frog’s free 500-URL crawl finds the broken links, redirect chains, and missing titles on any small-business site; and the two schema testers confirm your structured data is eligible for rich results. Together they cover most of a paid technical audit — the concepts behind what they’re checking are in our technical SEO guide.

Where free honestly ends

Three jobs the free stack can’t do: competitor keyword research at depth (you can see your own data; theirs needs paid crawlers), rank tracking at scale (GSC averages positions; daily tracking of 200 terms needs a tool), and backlink prospecting beyond your own profile. When those start mattering — usually when SEO becomes a channel worth $1,000+/month to you — a paid tool or an agency running one earns its fee (what that engagement costs is in our SEO pricing guide).

Free tools surface the problems; someone still has to fix them and write the content. When that someone shouldn’t be you, our SEO team works from this exact stack plus the paid heavyweights — tell us where you’re stuck and you’ll get an honest read on whether you need help or just the starter sequence above, within one working day.
