SerpLens: On‑Page Auditor

On‑page SEO audits: links, keywords, images, meta/social, sitemap, JSON‑LD. Runs locally; no data collection.

SerpLens is a lightweight Chrome extension that audits web pages for common on‑page SEO issues. Instantly analyze titles and descriptions, highlight broken links, review keyword density and readability, flag image SEO problems, and generate JSON‑LD schema—all without sending your data to external servers.
