Backlink Value Calculator
Score a prospect on authority, relevance, traffic and placement, and get a build-or-skip verdict. The same four gates every link is judged against before it is built.
Free SEO Tools
Free SEO tools that run entirely in your browser — nothing is uploaded, nothing is stored, no signup. Built by a link builder, not a SaaS company.
Built by someone who uses them daily on client work. 18 of 18 are live so far; the rest are on the way.
Start with these two
Most SEO tools are commodities. These two encode how a link actually gets judged before it is built, which is the part no other tool does.

Anchor Text Distribution Checker
Paste a backlink list and see the anchor mix — branded, exact-match, partial, naked, generic — with a warning when exact-match crosses a spam-risk threshold.
Every tool
All of them run entirely in your browser. Nothing you paste is uploaded, stored or sent anywhere.
On-page
- SERP Snippet Preview See a result exactly as it renders on desktop and mobile, with real pixel-width truncation rather than a character count.
- Title & Meta Description Checker Live pixel-width check on a title and description, with warnings before Google truncates them.
- Heading Structure Checker Paste a page and see its H1–H6 outline, with skipped levels and multiple H1s flagged.
- Image Alt Text Checker List every image on a page with its alt text, and flag the ones that are missing, empty or stuffed.
- Open Graph Preview Preview how a URL unfurls on Facebook, LinkedIn and X, and catch a missing og:image before you post.

No tool matches that name.
Want the judgement, not just the tool?
The tools apply the same standards used on client work. If you would rather someone did it for you, that is the service.
