Professional on-page SEO analysis tool with PageSpeed Insights integration

YASP — a professional on-page SEO analyzer with PageSpeed ​​Insights YASP is a lightweight and convenient extension for quick page audits right in the browser. It analyzes key on-page factors, highlights problem areas, checks hreflang, collects microdata (JSON-LD/Microdata/OG/Twitter), helps quickly open Wayback/WHOIS, and integrates with Google PageSpeed ​​Insights (Lighthouse: Performance, Accessibility, Best Practices, SEO). What it does SEO summary for the current tab Title, Description, Keywords (if any), length, and quality status. Canonical URL (rel="canonical") and validation. Robots meta directives and X-Robots-Tag header (noindex/nofollow, etc.). Page language (<html lang>) and Publisher/OG Site Name (if any). Word count on a page (text density assessment). Heading structure Number of H1…H6. Quick copying of a list of headings. Heading highlighting on a live page (on/off). Links Collecting all links, identifying external/internal ones.

Indexing and infrastructure Quick links to robots.txt and sitemap.xml of the current site. Indexability assessment based on meta tags/headers. Hreflang audit Collecting all <link rel="alternate" hreflang="…"> tags. Checking the HTTP status of final URLs (using a HEAD request). Attempt to determine a backlink to the current page: a content script loads the HTML for the target locale and looks for hreflang pointing back to the current URL and language. Microdata Open Graph and Twitter Card from meta tags. JSON-LD: parsing scripts <script type="application/ld+json"> — processing both arrays and single objects. Microdata (itemscope, itemtype, itemprop) with property tree construction, including nested structures. PageSpeed ​​Insights Run a Lighthouse audit for the current URL (via API).
