Free SEO Tools

Crawl any website and download every URL it links to as CSV, TXT, or JSON. Works straight from the live site, no sitemap required.

Trace every redirect hop with status codes and response times. Detect loops, long chains, protocol downgrades, and 302 misuse.

Find out why a page is not indexed. Checks status codes, noindex tags and X-Robots-Tag headers, robots.txt rules, canonicals, sitemap membership, and rendered content.

Find links that no longer work, internal and external together. Checks up to 50 links on a page for 404 errors, redirects, and timeouts.

Audit who a page links out to and on what terms. Destinations grouped by domain, with rel nofollow, sponsored and ugc, new-tab safety, and live status.

See which internal links a page makes in its own writing and which come from the template, grouped by destination, with anchor text, nofollow and live status.

Analyze robots.txt to see which AI crawlers and search engines are blocked, find sitemaps, and identify access issues.

Build a correct robots.txt from presets for WordPress, ecommerce, and AI crawlers. Decide which bots to allow, add your sitemap, copy the file.

Build a valid llms.txt from your own pages: the H1, blockquote summary and H2 link sections the proposal specifies, checked for relative URLs and duplicates.

Read every response header a URL returns, with the redirect chain timed hop by hop and X-Robots-Tag, header canonicals and caching gaps called out.

Build a robots.txt.liquid template that keeps Shopify's default rules in the Liquid loop and adds blocks for tag pages, vendor and type collections, filter parameters and AI crawlers.

Inventory every script tag on a Shopify product or collection page by origin: theme, Shopify platform, app and third-party. Flags async, defer and blocking scripts, sizes up to 30 external files and lists legacy ScriptTag API scripts.

Crawl any website and generate a valid XML sitemap you can download and submit. No signup, no software to install.

Test any XML sitemap against the sitemaps.org protocol. Catches namespace errors, bad lastmod dates, size limits, and cross-domain URLs.

Check a sitemap end to end: the file against the sitemaps.org protocol, then a live check of the URLs inside it. One pass, one health score.

Crawl every URL your sitemap declares and find the dead links, redirects, noindex pages, and canonical conflicts hiding inside it.

Pull every URL out of a sitemap or sitemap index and download the list as CSV, TXT, or JSON. Handles nested indexes and gzipped files.

Enter a domain and get its page count from the sitemap, broken down by section and by sitemap file, or from a live crawl when no sitemap exists.

Paste your sitemap URLs and get a valid sitemap index file back, with optional lastmod dates. For sites past the 50,000 URL limit that split their sitemaps.

Compare two sitemaps and see exactly which URLs were added, removed, and kept. Catch the pages a migration or a regenerated sitemap silently dropped.

Find where any website hides its sitemap. Checks robots.txt directives plus nine common paths, including WordPress and gzipped variants.

Turn any site into a visual tree of its structure. See how deep your pages sit and which sections carry the most URLs.

Validate canonical tags for self-referencing, protocol mismatches, trailing slash conflicts, noindex conflicts, and og:url consistency.

Validate hreflang tags for international SEO: self-referencing, return tags, x-default, language codes, and duplicate detection.

Validate structured data markup: required properties, date formats, nested entities, and JSON syntax. Supports all major schema types.

Check title tags, meta descriptions, Open Graph tags, Twitter cards, canonical URLs, robots directives, and viewport settings.

Write the title, description, and social share tags every page needs. Live character counts plus previews of how it will look in Google and on social.

See which words and phrases your copy actually leans on. Single word, two word and three word counts with density and first-mention position.

See your title and meta description the way Google renders them, measured in pixels. Desktop and mobile, with the exact character your snippet is cut at.

Turn a list of page titles into clean, readable URL slugs. Accents transliterated, filler words optional, and duplicates caught across the whole list.

Build branded, partial, long tail and naked URL anchor variations for any page, then audit the anchors you already have against a natural distribution.

Score any text on six readability formulas at once, then see which sentences are dragging the grade up. Passive voice and long sentences broken out separately.

Count the words on any URL, with the body copy separated from the nav, header and footer. Unique words, reading time, paragraphs and the heading outline.

Audit the alt text on every image on a page. Missing attributes kept apart from decorative alt="", plus image links with no name, filenames used as descriptions and duplicates.

Paste your meta tags and draw the card each platform renders, cut where it really cuts. Works on staging and on tags you have not deployed yet.

X retired its own validator in 2022. Check twitter:card on a live URL, see which tags X reads through the Open Graph fallback, and prove the image loads.

Fetch a live URL and read its og: tags the way a scraper does, then check the card image actually loads rather than only that the tag exists.

Read the H1 to H6 outline of any URL and find the skipped levels, empty headings and duplicate labels, with the page's own headings separated from its template.

Check up to 100 title tags at once, measured in pixels rather than characters, and find the duplicates across a set that no single-URL checker can see.

Check up to 100 meta descriptions at once, measured in pixels, and find the duplicates, empty tags and descriptions that just repeat the title.

Grade a page or draft against 20 weighted signals plus an AI judgement kept clearly apart. The score shows its own arithmetic, and every row prints its method.

Write 12 candidate titles from a URL or a topic, each measured in real pixels at Google's desktop and mobile widths, with the brand appended by code and the keyword checked.

Write 12 H1 and blog headlines from a URL or a topic, each checked against the house style: length band, keyword present, and none of the template tells or bait an editor would cut.

Write alt text for every image on a page that has none or sits in an unnamed link, never for decorative ones, with each description checked against the alt checker's own rules.

Check which of Google's helpful content signals a page actually shows: author, dates, sourcing, content ratio and ad load. No invented score.

Sample 20 products from a Shopify store and check that the /collections/x/products/y copy, the plain /products/y page and the ?variant= URL all canonicalise to the plain product URL.

Fetch one Shopify, WooCommerce, BigCommerce or Magento category URL and get 13 checks with the observed values: title and description length, H1, canonical, pagination, robots, category copy word count, product links, BreadcrumbList and CollectionPage schema, image alt coverage and filter URLs.

Tell Google your business name, address, phone, and opening hours in the format it reads literally. Type your details, copy the code, paste it into your site.

Describe a Search Console filter in plain English and get an RE2 regex back, explained token by token, with a live match tester.
