WebmasterNinja: SEO Chrome extension

An SEO extension for Chrome: audit any page for on-page SEO, link health and AI-citation readiness, with your Search Console data.

WebmasterNinja is an SEO extension for Chrome. It reads whatever page is open and reports three things: its on-page SEO, its link health, and whether the page is built to be quoted by AI answer engines. On sites you own, your Google Search Console numbers sit beside all of it. Every result points at what produced it: your own Search Console figures, the page's own HTML, or a cited document. Where none of those support a suggestion, the section stays empty rather than filling with something plausible. On your own sites (Search Console) - Wins: striking-distance queries (position 4-20), ranked by estimated clicks using this page's own click-through-rate curve where there's enough data, or a typical-CTR-by-position fallback otherwise. An estimate, not a promise. - Decay: queries quietly losing clicks versus the prior period, with a significance check so normal noise isn't flagged as a real drop. - Explore: switch between Queries, Pages, Countries, Devices, Dates, and Structure to see any dimension of your Search Console data for the page, with copy/CSV export. - Verdict-first: the popup opens on a one-line read of the page ("holding, but 6 queries are decaying") with a link straight to why, instead of a wall of numbers to interpret yourself. On any page, including a competitor's, no sign-in needed - Competitor-audit mode: point it at any page you don't own and get the full on-page SEO and GEO audit. Traffic-dependent tabs are cleanly hidden (not greyed out) since that data needs Search Console ownership. - On-page SEO hygiene: titles, headings, canonical, hreflang, indexability. - Link health: broken links kept separate from links that are only bot-blocked. - GEO readiness: is the page structured so ChatGPT, Perplexity, and AI Overviews can actually cite it. Eligibility gates and scored signals shown separately, with the sources behind every row. Page or section? (new in 3.2) - For each query this page receives, it answers one question: does one of your pages already own it? Three calls come out of that. Fold together when two of your pages both rank for it and their query sets already overlap as near-duplicates. Add a section when one page owns the query but its text barely mentions it. No page covers this when there is real demand across two Search Console periods and nothing on the site mentions it. - Every call names the pages and shows the numbers behind it: impressions per page, share of the query, mention counts, and the two windows compared. - Most queries get no call at all, and that is the normal result. A footer line accounts for every query checked and says why each one was passed over, so a blank panel is verifiable rather than silent. - Built on the same two engines already in the tool: near-duplicate detection (Google patent US8108412B2) and demand match (US7536408B2). No new data source, no extra API call. Track your fixes - Since last audit: re-audit a page and see exactly what changed. Score delta, which gates closed, which checks flipped, since the last time you audited that URL. Compares the tool's own past measurements, never a ranking or traffic promise. - Audit export: one button exports everything the tool measured (scores, gates, fix rows, citations, brief) to Markdown or JSON. Nothing beyond what was actually computed. For writers and editors - A one-click, copy-paste content brief: the sections to add and questions to answer, grounded only, nothing made up. - Title and meta drafts: on pages that need it, get 2-3 draft title/meta options built from the page's own topic and your Search Console queries. Every draft is labeled "Draft — review before publishing" and runs through a grounding check first: no invented numbers, no superlatives, no claims about the result. If nothing grounded can be produced, it says so instead of guessing. Free. Runs in your browser. Sign in with Google to see your own Search Console data, or use the on-page and GEO audits on any site without an account. Also known as An SEO audit extension, an on-page SEO checker, a Chrome SEO extension, or a Google Search Console extension. It covers all of those jobs in one popup: the on-page and technical checks, the link scan, the AI-readiness audit, and your Search Console performance for the page you are looking at. On what it will not do. There is no summary score, no invented content gap, and no ranking or traffic prediction anywhere in the output. Signals that have not held up under evidence, including llms.txt and schema as a citation lever, are left unscored rather than padding a number.
