I Built an SEO Tool That Lied to Me. So I Rebuilt It.

A developer rebuilt SEOCORE, a personal SEO crawler, after finding that its original audit scores looked plausible but were often wrong.

The new TypeScript CLI now crawls real sites, follows redirects, respects robots.txt, renders JavaScript, and reports issues in context.

Instead of a misleading single score, the tool focuses on trustworthy checks, crawl graphs, snapshot diffs, and clearer output.

The story highlights how polished SEO tools can still mislead users when their logic is unreliable, and why correctness matters more than flashy scoring.
