Title Tag & Meta Description Length Checker

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.

Test structured data markup on any URL: 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 tag 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.

Debug the og: tags on a live URL the way a scraper reads them, 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.
