Meta Tags Analyzer

Open your page, view its source, paste the HTML here and get a checklist of the on-page basics: title and description length, canonical, robots, viewport, headings, image alt text, social tags and structured data. It works on the HTML you give it, in your browser, so private or unpublished pages are safe to check. Built for Australian users, with nothing sent to a server.

    How do I check the meta tags on a page?

    View the page source (right-click and choose View page source, or press Ctrl+U), copy it all, and paste it here. The tool reads the head and body and lists what is present or missing: title, meta description, canonical link, robots, headings, image alt text, Open Graph, Twitter card and JSON-LD. It cannot fetch live addresses because browsers block reading other sites.

    Reading the results

    A tick means the item is present and within a sensible range. A cross is a prompt to look, not a penalty. For example, no-index on a thank-you page is correct, and the checker would flag it as 'not indexable' only because it cannot know your intent.

    Fix missing titles, descriptions and headings first, because they are cheap to fix and affect every search result.

    Why it uses pasted HTML

    Browsers do not let one web page read the HTML of another site, so a tool in the browser cannot fetch a live address. A server-based tool can, but that would mean sending your address to a third party. Pasting the source keeps the analysis on your device.

    To write the tags it finds missing, use the meta tag generator.

    How this is calculated

    The rule, step by step, so you can check any figure by hand.

    • the pasted HTML is parsed with the browser's own HTML parser
    • title and description lengths are compared with about 15 to 65 and 70 to 165 characters
    • one h1 is expected; images without an alt attribute are counted
    • each JSON-LD block is parsed to check it is valid JSON

    The checks are guidelines drawn from search engine advice, not rules. A page with two h1 headings can rank well, and a short title can work if it is clear. The tool highlights what is missing so you can decide.

    Because the analysis works on pasted source, it sees the HTML as delivered. Pages that build their content with JavaScript show less here than a search engine sees after rendering, so use Google's URL Inspection tool for those.

    A worked example

    The HTML of a service page with a title, description, one h1 and valid JSON-LD.

    1. Title52 characters, good
    2. Description158 characters, good
    3. Headings1 h1, 4 h2
    4. JSON-LD1 valid block
    5. Score10 of 12

    A list of what to fix.

    Start with anything marked with a cross.

    For Australian sites

    Check that your title and headings use the spelling your Australian audience searches and that local pages name the place. If your site serves both Australia and New Zealand, each page should have its own tags, and hreflang between them.

    What it leaves out

    Page speed, mobile rendering, links, indexation and ranking are not checked. For those, use Google Search Console and PageSpeed Insights.

    What this calculator does not do

    • Works on pasted HTML only
    • JavaScript-built pages look emptier than they are
    • Guidelines, not rules
    • No speed, link or ranking checks

    Common questions

    How do I get a page's HTML?

    Right-click the page and choose View page source, then copy everything.

    Why can't it check a web address?

    Browsers block one site reading another's HTML. Pasting the source avoids that.

    What is a good title length?

    About 50 to 60 characters.

    Is one h1 required?

    It is a good practice, not a rule, but one clear main heading helps.

    Is my HTML uploaded?

    No. It is analysed in your browser.
