SEO analysis, SEO toolkit. One call for an on-page SEO analysis of a URL: the SEO audit (title and description lengths, canonical, headings, alt text, structured data, score, issues), the top keywords and two-word phrases with their density, the social preview (OpenGraph, Twitter card), the favicon, and robots.txt access with its sitemaps. Server HTML only. Cheaper than the tools one by one. Use before publishing, for an SEO report or to compare a competitor's page.
