Free SEO tools that don't need a sign-in

Enter your domain and IndexNow key. We verify the key file is hosted correctly — reachable, plain-text, exact match — so Bing, Yandex, Seznam, and Naver accept your submissions.

A 0–100 score for how findable your site is across Google and AI search — robots.txt, llms.txt, structured data, sitemap, canonical, Open Graph, HTTPS.

Paste a page URL and get a 0–100 score for whether AI engines can lift a clean, attributable answer from it — answer placement, quotable sentences, dated claims, brand adjacency, structure — plus the exact edits that close the gap.

Enter your domain (and brand). We ask an AI model which sources it would cite for real queries and check whether you show up — then scan your homepage for the off-site brand signals (YouTube, social profiles) that, per Ahrefs, correlate most with AI visibility.

Paste your domain. We read its robots.txt and tell you which AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot, Bytespider…) can crawl your content — and which are blocked.

Paste or fetch an llms.txt and lint its structure, sections, and links — what LLMs use to pull clean citations.

Paste a User-Agent string and identify AI crawlers, search bots, SEO tools, and browsers behind it.

Paste any URL. We fetch it live and run every signal Google uses to decide if a page can be indexed — HTTP status, redirects, X-Robots-Tag header, meta robots, canonical, and robots.txt — then give one plain-English verdict.

Paste a page's HTML. We extract the canonical URL, robots meta, title, description, hreflang, Open Graph, and JSON-LD types — and flag indexability bugs.

Type any domain to see its Ahrefs Domain Rating — a 0–100 score of backlink-profile strength versus the rest of the web, on a logarithmic scale. Free, no API key. Data: Domain Rating by Ahrefs.

Fetch a URL and extract every JSON-LD / microdata Schema.org block. We validate required fields and flag which types are eligible for Google rich results.

Pick a type — Organization, WebSite, Article, Product, FAQ, Breadcrumb, LocalBusiness — fill a form, and get copy-paste JSON-LD with live required-field validation.

Preview how your title and description render on Google desktop and mobile, with pixel-accurate truncation.

See how a URL renders when shared on Facebook, LinkedIn, Slack, and X — and which tags are missing.

Follow every HTTP redirect hop for a URL and surface long chains and HTTPS downgrades.

Validate hreflang annotations, x-default, self-reference, and that every alternate reciprocates.

Paste a robots.txt plus a URL and User-Agent; we tell you which rule matches and whether it's allowed.

Compare two sitemaps or URL lists — added, removed, unchanged — and copy the added set.

Paste a messy list of URLs and get back a deduped, normalized, validated, sorted list ready to submit.

Tell us how many URLs over how many days; we work out free pushes, packs needed, and the bottom-line cost.

Answer a few questions about your site — age, authority, how you submit, content type — and get a realistic window for how long Google takes to index a new page, plus the levers that speed it up.

Map your daily URL volume against Google's Indexing API (200/day) and URL Inspection (2,000/day) limits. See how many service accounts a DIY setup needs — and where IndexerNow's free tiers and credits land.
