On-page SEO and content

Image ALT and Responsive Image Analyzer Inspect img, picture and source elements for missing or intentionally empty alt text, dimensions, lazy loading and responsive-image signals. Meta Tag Analyzer Extract title, meta description, robots, canonical, Open Graph and X card fields from a public page and review conflicts or omissions. Canonical and Hreflang Validator Validate the preferred URL, language and region codes, x-default and a bounded set of reciprocal hreflang references. Meta Tag Generator Create title, description, robots, canonical, Open Graph, X card and viewport markup with a live preview and copy-ready HTML. Keyword Idea Generator Create grouped thematic and long-tail variations from a seed phrase without inventing search volume, competition or traffic forecasts. Keyword Density Analyzer Measure word and phrase frequency, density and context without treating any percentage as an ideal SEO target. SERP and Social Sharing Preview Preview title, description, URL and image treatments for search, Open Graph and X cards from entered fields or fetched metadata. Verified Corpus Text Check Automatically compare text with a verified corpus of public sources and inspect exact matches, measured coverage and source URLs. Structured Data Inspector Extract JSON-LD, Microdata and RDFa, inspect declared schema.org types and identify syntax or basic structural problems. Keyword Visibility Workbook Filter a Search Console CSV or TSV export by query and domain, or prepare a transparent manual search workflow without automated SERP scraping. Compare Two Texts Compare two submitted texts through exact normalized five-word sequences and review coverage, Jaccard similarity and concrete shared passages. Code-to-Text Ratio Analyzer Compare extracted visible text bytes with the fetched HTML size as a diagnostic measure, not a search ranking metric.
