Free Meta Tag Checker and SERP snippet preview

Enter a page URL to see its title and meta description as a Google result on desktop and mobile, measured in pixels rather than characters. We flag what makes Google rewrite titles and check the robots, viewport, charset and lang tags. Free, no account needed.

Enter the full URL of the page you want to preview.

Reading the result

What your meta tag check means

Search results cut text by width, not by character count. A title of capital Ws runs out far sooner than one of lower-case i's, so the report measures every character with real font metrics.

  • Search result preview

    Your title, description, site name and URL breadcrumb laid out like a result, with the text cut where it would be cut on desktop and on a phone. If the page has no title, the preview shows the H1, which is what Google often falls back to.

  • Title and description

    Each one's width in pixels against the space available (about 600 px for titles, about 920 px for desktop descriptions and 680 px on mobile), its length in characters, and whether it fits, is cut off, is too short or is missing.

  • Page details

    The site name search results show (from og:site_name, your WebSite structured data, or the domain), the breadcrumb built from your URL, the H1, whether your brand appears twice in the title, and whether the page can appear in results at all.

  • Other meta tags that matter

    robots and X-Robots-Tag for indexing, viewport for phones, charset for character encoding, lang for language, and the canonical URL. Each is marked OK or explains what's wrong.

How it works

How the meta tag checker works

  1. 1

    Enter the page URL

    Use the exact page you want to rank. If it redirects, we check the page it lands on, because that is the page search engines show.

  2. 2

    We read the head of the page

    The title, meta description, robots, viewport, charset and canonical tags, the html lang attribute, the H1 and the site name sources.

  3. 3

    We measure in pixels

    Each character is measured with Arial's real advance widths at the sizes results use: 20 px for titles and 14 px for descriptions. Text that runs past the limit is cut at the last whole word with an ellipsis.

  4. 4

    We flag rewrite risks

    Missing, empty, very short or very long titles, a brand repeated in the title, titles in capitals, and titles that share no words with the H1 are the common reasons Google rewrites a title.

Accuracy and limits

What the meta tag checker does and doesn't do

  • Cut-off points are approximate. Google truncates by pixel width, and the exact width varies by device, browser and layout changes.
  • It can't predict whether Google will rewrite your title or description; it flags the patterns that make a rewrite more likely.
  • It reads the HTML your server returns. Tags changed by JavaScript after the page loads aren't included.
  • It checks one page. Duplicate titles across a site need a crawl.
  • One page per check: three a day without an account, fifteen when signed in.

The TaskGlaze site audit finds missing, duplicate and over-long titles and descriptions across every page of your site. See the site audit.

Guide

How to write titles and meta descriptions that get clicked

Your title and description are the advert for your page in search results. These habits keep them intact and worth clicking.

  • 1. Lead with what the searcher wants

    Put the main topic or keyword in the first few words of the title. If the end is cut off, the part people read still matches their search.

  • 2. Aim for about 50 to 60 characters

    Most titles of that length fit in 600 pixels. Wide letters such as M and W use more space, so check the pixel width rather than counting characters.

  • 3. Use your brand once

    Add the brand at the end, separated by a dash or pipe, if there is room. Repeating it, or adding long boilerplate to every title, is a common reason Google rewrites titles.

  • 4. Make every title unique

    Pages with the same title compete with each other and give searchers no reason to choose one. Include what is specific to the page.

  • 5. Write descriptions as a promise

    Say what the visitor will get from the page in 140 to 155 characters. Google bolds words that match the search, so use the words searchers use.

  • 6. Front-load the description

    Phones show less description than desktops. Put the key message in the first 110 or so characters so it survives on both.

  • 7. Keep titles and headings aligned

    When a title promises something the H1 doesn't mention, Google may use the heading instead. Make the two describe the same thing.

  • 8. Get the basics right in the head

    One title, one meta description, a viewport set to width=device-width, a charset of utf-8 in the first 1024 bytes, and a lang attribute on the html tag.

The meta tags that matter, and what they do

Dozens of meta tags exist; these are the ones search engines and browsers act on.

Common mistakes

Common meta tag mistakes

  • The same title on every page

    A template that outputs only the brand, or "Home", on every page. Search engines can't tell the pages apart, and neither can searchers.

  • Keyword-stuffed titles

    Lists of keywords separated by commas or pipes read as spam and are very likely to be rewritten.

  • Titles cut off before the point

    The important words sit at the end, past the cut-off, so searchers see only boilerplate.

  • No meta description

    Google writes its own snippet from the page text, which may be a menu, a cookie notice or a sentence out of context.

  • A description that repeats the title

    It wastes the second line of the result. Use it to say what the page offers.

  • Two title or description tags

    Usually a theme and a plugin both writing one. Only one is used, and you don't choose which.

  • A missing viewport tag

    Phones render the page at desktop width and zoom out, which makes it hard to use on mobile.

  • noindex left on from development

    The snippet doesn't matter if the page can't appear at all. The report checks the robots tag and header too.

Meta Tag Checker FAQ

Meta tag checker questions, answered

Pixel widths, truncation, rewrites and the tags that matter.

What is a meta tag checker?

A meta tag checker reads the tags in a page's <head> that control how it appears in search results and how browsers handle it: the title, meta description, robots, viewport, charset and more. This one also previews the title and description as a search result, measured in pixels.

How long should a title tag be?

Short enough to fit in about 600 pixels, which is usually 50 to 60 characters. Pixel width matters more than characters because letters differ in width, so a title in capitals is cut much sooner than one in lower case.

How long should a meta description be?

About 140 to 155 characters, or roughly 920 pixels on desktop. Phones show less, about 680 pixels, so put the key message first.

Why does Google show a different title?

Google rewrites titles it finds missing, too long, too short, stuffed with keywords, full of repeated boilerplate such as the brand twice, or out of step with the page's main heading. The report flags each of these patterns.

Why does Google ignore my meta description?

Google uses the description when it describes the page well for the search. For other searches it picks text from the page that matches better. A specific, accurate description is used more often.

How is pixel width measured?

Each character is measured with Arial's advance widths, the font search results use for snippets, at 20 px for titles and 14 px for descriptions. The cut-off points are approximate, because Google's layout varies by device and changes over time.

Do meta keywords matter?

No. Google has ignored the meta keywords tag for many years, so this check doesn't report it.

What does the viewport tag do?

It tells phones to use the device's width instead of a desktop-sized canvas. Without width=device-width, the page is shown zoomed out and hard to read on mobile.

Where does the site name above a result come from?

Google uses the site name from your WebSite structured data and og:site_name among other signals, and falls back to the domain. The report shows which source your page provides.

Does the checker show Open Graph tags?

This tool focuses on search results. To see how the page looks when shared on social networks and in chat apps, use the Open Graph checker in the list of free tools below.

How many checks can I run?

Three per tool per day without an account, or fifteen per tool per day when you are signed in to your TaskGlaze account. Each free tool has its own count.

Is it safe to check any URL?

We check every link against public lists of phishing and scam sites before loading it, and refuse ones that look unsafe. A refused link doesn't use one of your daily checks.
