Free SEO Tools
Check, validate, and audit your site's SEO, one page at a time. Need a full site audit? Try CrawlRaven free.
Start here
If you are not sure which check you need, run the whole page through one audit and work from what it finds.
Crawling and indexing9 tools
Whether a search engine can reach a page at all, and what is stopping it: status codes, redirect chains, robots rules, and noindex directives.
Website URL Extractor
Crawl any website and download every URL it links to as CSV, TXT, or JSON. Works straight from the live site, no sitemap required.
Redirect Chain Checker
Trace every redirect hop with status codes and response times. Detect loops, long chains, protocol downgrades, and 302 misuse.
Page Indexability Checker
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.
Broken Link Checker
Find links that no longer work, internal and external together. Checks up to 50 links on a page for 404 errors, redirects, and timeouts.
External Link Checker
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.
Internal Link Analyzer
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.
Robots.txt Tester
Analyze robots.txt to see which AI crawlers and search engines are blocked, find sitemaps, and identify access issues.
Robots.txt Generator
Build a correct robots.txt from presets for WordPress, ecommerce, and AI crawlers. Decide which bots to allow, add your sitemap, copy the file.
llms.txt Generator
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.
Sitemaps9 tools
Find, generate, validate, and diff XML sitemaps. Reading a sitemap tells you what a site says it has; crawling it tells you what is actually there.
XML Sitemap Generator
Crawl any website and generate a valid XML sitemap you can download and submit. No signup, no software to install.
XML Sitemap Validator
Test any XML sitemap against the sitemaps.org protocol. Catches namespace errors, bad lastmod dates, size limits, and cross-domain URLs.
Sitemap Checker
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.
Sitemap Crawler
Crawl every URL your sitemap declares and find the dead links, redirects, noindex pages, and canonical conflicts hiding inside it.
Sitemap URL Extractor
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.
Sitemap Index Generator
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.
Sitemap Comparison
Compare two sitemaps and see exactly which URLs were added, removed, and kept. Catch the pages a migration or a regenerated sitemap silently dropped.
Sitemap Finder
Find where any website hides its sitemap. Checks robots.txt directives plus nine common paths, including WordPress and gzipped variants.
Visual Sitemap Generator
Turn any site into a visual tree of its structure. See how deep your pages sit and which sections carry the most URLs.
On-page and SERP15 tools
The elements on the page itself, plus how the result renders once it gets there: titles, meta descriptions, canonicals, hreflang, and snippets.
Canonical Tag Checker
Validate canonical tags for self-referencing, protocol mismatches, trailing slash conflicts, noindex conflicts, and og:url consistency.
Hreflang Validator
Validate hreflang tags for international SEO: self-referencing, return tags, x-default, language codes, and duplicate detection.
Schema & JSON-LD Validator
Validate structured data markup: required properties, date formats, nested entities, and JSON syntax. Supports all major schema types.
Meta Tag Checker
Check title tags, meta descriptions, Open Graph tags, Twitter cards, canonical URLs, robots directives, and viewport settings.
Meta Tags Generator
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.
Keyword Density Checker
See which words and phrases your copy actually leans on. Single word, two word and three word counts with density and first-mention position.
SERP Snippet Preview
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.
URL Slug Generator
Turn a list of page titles into clean, readable URL slugs. Accents transliterated, filler words optional, and duplicates caught across the whole list.
Anchor Text Generator
Build branded, partial, long tail and naked URL anchor variations for any page, then audit the anchors you already have against a natural distribution.
Readability Checker
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.
Page Word Counter
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.
Image Alt Checker
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.
Open Graph Preview
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.
Twitter Card Validator
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.
Open Graph Checker
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.
Schema generators6 tools
Valid JSON-LD for the rich results Google still supports, with the required fields filled in and a preview of the result each one earns.
Local Business Schema Generator
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.
