Browse toolsBuilt the way SEOs actually work
No fluff, no upsells, no PDFs of 10 tips. Just tools that work and writing that holds up under real SERPs.
Fast by default
Astro 7 + edge cache + zero JS where possible. Sub-1s loads on every page, even the long guides. 98 Lighthouse.
Private by design
Tools run 100% in your browser. We never see your URLs, HTML, or copy — every parser is local code you can inspect in your devtools.
Field-tested, not theoretical
Every guide ships with a real example, real numbers, and a workflow you can copy — from sites that actually rank.
Trusted by the people who ship rankings
Real feedback from practitioners who've used SEOKit24 in their day-to-day workflow.
I ran the Sitemap Validator on a client site that had been crawled 3x/week for 6 months without indexing. Found 4 orphan pages and 2 canonical conflicts. Fixed them, saw index count go up 18% in 2 weeks.
The Meta Tag Analyzer is my pre-launch checklist. I catch duplicate descriptions, missing OG tags, and h1 clashes before they ship. Saves me at least 20 minutes per project.
Finally an SEO tool that runs client-side. My clients appreciate that their URLs never leave their browser. The keyword density checker caught a case of keyword stuffing I missed in manual review.

Yes. All 6 tools are free to use, no signup required. Guides and blog posts are free forever. We monetize through discreet affiliate links and enterprise consulting — not your data.
No. The free tools parse everything in your browser — we never see the HTML or text you paste. Fetching a live URL goes browser-to-target, not through us; only the explicitly opt-in first-party relay (for CORS-blocked sites) ever sees the URL itself. Beyond that, only anonymous GA4 page-views are collected.
Between client work we ship new field-tested posts, and we refresh the guides and older posts quarterly. Subscribe to the newsletter to never miss a drop.
For enterprise teams yes — see the contact page for audit & retainer options. For solo SEOs, the guides and tools should cover 90% of what you need.
