Best Free SEO Tools
A florist paying £240 a month to an SEO agency asked me to sanity-check what she was getting. The monthly report was beautiful: rank-tracker graphs, "domain authority" trend lines, a keyword table. What the report didn't mention: her site had no meta descriptions, her Google Business Profile listed old Sunday hours, and her sitemap had never been submitted. Every one of those fixes was free, and together they'd have done more than the agency's quarter. This isn't an anti-agency story — good ones exist — it's a sequencing story: for small sites, the free tools cover the fundamentals, and the fundamentals are usually what's missing. Here's the free stack, in the order it pays.
Google Search Console: not optional, and somehow still skipped
The only tool that shows what Google actually does with your site — which queries show your pages, what gets clicked, what's indexed, what's broken. Free, first, forever. The florist's setup took twenty minutes including sitemap submission, and her first look at the queries report reshaped her page titles the same week. If you install one thing from this article, it's this; if you check one thing monthly, it's the performance report's impressions-then-clicks trend.
The on-page basics: metadata, structure, honesty
Every page needs a title (~60 characters) that makes its specific promise and a description (~155) that answers "what do I get for clicking" — a free meta tag generator handles the format while you supply the promise. Add a density check not to hit a magic number (there isn't one) but to catch accidental robot-speak, and headings that state answers rather than tease them. This layer is an afternoon for a small site, and it was the florist's biggest gap.
The technical trio: sitemap, robots, speed
A sitemap listing your real pages, submitted once in Search Console; a sane robots.txt (and a check that no Disallow: / survived from staging — the classic self-inflicted vanishing); and page speed, where the free fix is almost always images — compress everything over 300KB and re-test in PageSpeed Insights (also free). For a 20-page site this whole layer is one honest afternoon, not a subscription.
Keyword research on £0
The free method that outperforms its price: type your topics into Google and read the autocomplete and "People also ask" boxes (that's live demand, verbatim); check competitors' page titles on page one (that's the standard you're differentiating from); use a chat model to cluster and expand your list and to guess intent behind phrases. Paid tools add volume estimates and scale — genuinely useful at hundreds of pages, decoration at twenty. The florist's best-performing page came from an autocomplete phrase no paid tool had surfaced, because its "volume: 0" queries are where small businesses live.
Local SEO: the free tools with the biggest lever
For any business with a location, Google Business Profile outranks everything else on this page combined: current hours, real photos monthly, every review answered (AI-drafted, human-signed), posts when something changes. Free, and most competitors neglect it — the florist's old Sunday hours were costing actual Sunday customers. Pair it with consistent name-address-phone across directories, and you've done what "local SEO packages" mostly charge for.
What the free stack honestly can't do
Competitive backlink analysis, rank tracking at scale, content scoring across hundreds of pages, technical crawls of large sites — the paid tools (Ahrefs/Semrush class) earn their fees there, when you're big enough to need them. And no tool, free or paid, writes the thing that actually ranks: a page that answers its question better than what's currently on page one. Tools tune the machine; the content is the fuel. Do the free stack this month — Console, metadata, technical trio, Business Profile — and revisit the agency question after. The full walkthrough for beginners lives in our complete SEO guide.
Free SEO stack that covers 80%
For a new site, four free tools replace 80% of what beginners pay for. The last 20% (rank tracking, backlinks) is where paid starts to matter.
| Task | Free tool | What it does | When to pay |
|---|---|---|---|
| Meta title/description | Meta Tag Generator | CTR-focused snippet | When you A/B test at scale |
| Keyword check | Keyword Density | Spot stuffing / gaps | When you need Search Console data |
| Sitemap | Sitemap Generator | XML for GSC/Bing | Large sites (>10k pages) |
| Robots.txt | Robots Generator | Block / Allow correctly | Complex crawl budgets |
Editor’s note: We audit new sites and the #1 fix is a shorter meta title (55 chars). Free AI nails that in one click; people overthink the rest.
SEO that moves the needle this week
- One title: 55 chars, keyword + benefit
- One internal link per new post (older relevant post)
- Compress one hero image to <120KB
