Free tools

SEO tools that do one thing properly

Six free tools built while working on this site, plus one paid. No sign-up, no email capture, no upsell — they either help or they don't.

SERP Snippet Preview

See how your title and meta description render in Google, measured in pixels rather than characters — which is what actually determines truncation.

OPEN TOOL →

AI Crawler Access Checker

Check whether ChatGPT, Claude, Perplexity and Gemini are allowed to read your site. Many sites block them by accident through a plugin default.

OPEN TOOL →

Canonical Health Checker

Verify your canonical tag actually resolves to a live 200 page and isn't quietly pointing at a redirect — a common fault after any migration.

OPEN TOOL →

Social Share Preview

See how your link renders on LinkedIn and X before you post it, and which Open Graph tags are missing. A link with no image gets a fraction of the clicks.

OPEN TOOL →

On-Page SEO Analyzer

The big one — around 40 checks on any URL covering meta, headings, content, images, links, technical setup and structured data, scored and grouped.

OPEN TOOL →

Keyword Explorer

Real long-tail keyword suggestions from Google autocomplete, expanded across 65 modifier patterns and classified by search intent. No invented volume numbers.

OPEN TOOL →

Site Change Monitor

Alerts you when a noindex appears, a canonical repoints, or a page starts redirecting — the breakages nobody notices until traffic drops. Runs on your own machine.

Free SEO Tools Directory

An honest list of every free SEO tool worth using, labelled as genuinely free, free with a real limit, or free in name only. No affiliate links.

Each of these came out of a problem hit while building this site. The canonical checker exists because 29 canonicals here were pointing at redirects after a host migration — documented in technical SEO examples.

Useful? A link from your site helps more than anything else — it's the one thing a new site can't manufacture.
