SEO Tools
Free SEO Tools
Three tools I built for the on-page checks I run every week: measuring how a snippet will actually render in Google, auditing how often a keyword really appears, and catching the sentences that make a page hard to read. Each one runs entirely in your browser — nothing you paste is uploaded, stored, or logged anywhere.
Meta Description & Title Checker
Measure title and description length in pixels with a live Google SERP preview for desktop and mobile before you publish.
- Live Google SERP preview for desktop and mobile
- Real pixel-width measurement, not character estimates
- Truncation warnings before Google rewrites your snippet
- Focus keyword highlighting and placement checks
Keyword Density Analyzer
Audit keyword and phrase saturation, spot over-optimisation, and export CSV reports for on-page reviews.
- One, two and three-word phrase (n-gram) analysis
- Multi-word focus keyword tracking with stem variations
- Keyword placement and first-paragraph prominence checks
- CSV export for client-ready on-page reports
Content Readability Analyzer
Check Flesch, Flesch-Kincaid, Gunning Fog, SMOG and ARI scores, then fix the long sentences and passive voice it flags.
- Five readability formulas scored side by side
- Passive voice, adverb and transition-word detection
- Sentence-by-sentence length flagging
- Reading time and paragraph structure checks
These tools cover the on-page half of the job. For the crawling, indexing and site-architecture side,
