A meta tag checker reads a page's head and body and reports the SEO tags it finds. This one scores the title, description, robots, canonical, H1 and Open Graph tags and previews the Google result. SEOs and site owners use it to spot problems quickly.

How to use the meta tag checker
- Enter the full URL of the page you want to review. Pages that need a login cannot be fetched.
- Run the check. Our server requests the page, follows any redirects, and reads the HTML head and body.
- Read the score and the checklist. Each item is marked as passing, a warning or a problem, with a short explanation.
- Compare the Google result preview with what you want users to see. Title and description lengths are shown in characters and in pixels.
- Fix the issues in your CMS or template, then run the check again to confirm the change.
- To rewrite the snippet visually, use the one-click link to open the page's title and description in the SERP Simulator.
The checker shows what the server sends. If your title or description is set by JavaScript after load, check that the final HTML contains it, since not every crawler runs scripts.
What this meta tag analyzer checks
The HTTP status of the URL and any redirects on the way. A page that redirects or errors cannot rank as you expect.
Length in characters and in pixels, because Google truncates by width. Desktop titles cut off at about 600 pixels.
Length in characters and pixels. Roughly 920 pixels is the visible width on desktop, though Google may rewrite it.
Noindex in the robots meta tag and in the X-Robots-Tag header, which can quietly remove a page from search.
Whether it points to itself, to another URL, or appears more than once. Duplicates and conflicts are flagged.
H1 count, viewport tag, html lang, Open Graph tags, images missing alt text, and word count.
Title tags: length, pixels and wording
Google builds the blue link in search from your title tag, and it truncates by pixel width rather than a fixed character count. That is why this meta title checker shows both numbers. As a working rule, keep titles near 60 characters, then confirm the pixel width stays under about 600.
Wide letters such as W and M use more space than narrow ones such as i and l. A 58-character title full of capital letters can be cut off, while a 65-character title in lowercase may fit. Do not chase the exact limit. Aim for a clear title that leads with what the page is about.
Google also rewrites titles when it thinks yours does not describe the page well. Its documentation on title links explains this. Titles that are descriptive, unique per page and free of keyword stuffing are the least likely to be replaced. If the checker shows a title longer than your target, trim words from the end, not the start.
Meta descriptions: what they do and do not do
A meta description does not affect rankings. Google says it may use the tag as the snippet when it describes the page better than the page text does, and it often builds its own snippet from the content instead. You can read more in its guide to snippets. So write descriptions for people who are deciding whether to click.
| Do | Avoid |
|---|---|
| Summarize the page in one or two clear sentences | Copying the same text onto every page |
| Include the main topic naturally | Stuffing in repeated keywords |
| Say what the visitor gets | Leaving the tag empty on important pages |
| Keep within about 920 pixels on desktop | Writing paragraphs that get cut mid-sentence |
If the meta description checker shows no description, Google will still pick a snippet. Even so, writing one gives you control on high-value pages.
Indexing signals that quietly break pages
The most expensive problems on this list are not about length. They are about whether the page can be indexed at all.
- Noindex left on after launch. A
noindexin the robots meta tag or the X-Robots-Tag header tells Google to drop the page. The checker reads both places. - Canonical pointing elsewhere. A canonical to another URL asks Google to index that URL instead. This is correct for duplicates and a disaster when set by mistake.
- Multiple canonicals. Two different canonical tags give conflicting signals, and Google may ignore both.
- Missing viewport. Without it, mobile rendering suffers and mobile-first indexing sees a poor page.
- Wrong html lang. The language attribute helps browsers and assistive tools, and should match the content.
- Images without alt text. Alt text describes images to screen readers and to Google Images. The checker counts images that lack it, so you can fix the worst offenders first.
- Thin pages. The word count is a prompt, not a target. A page with a few dozen words may be too thin to satisfy the search it targets, so ask whether it answers the question fully.
The checker reports signals, not rankings. A perfect score means the on-page basics are in order, not that the page will rank. Content quality and links still decide that.
Frequently asked questions
What is a meta tag checker?
A meta tag checker fetches a page and reviews its head elements, including the title, meta description, robots directives, canonical, viewport and social tags. It reports lengths, flags missing or conflicting tags, and shows a preview of the Google result so you can fix problems quickly.
How long should a title tag be?
Aim for around 60 characters, or under roughly 600 pixels on desktop. Google truncates by pixel width, so wide letters shorten the usable space. Put the main topic first so the most important words survive any trimming, and keep each title unique across the site.
How long should a meta description be?
About 140 to 155 characters, or under roughly 920 pixels on desktop. Google may show a different snippet, so length is a guide, not a rule. Write a clear summary that helps a searcher decide to click, and avoid repeating it across pages.
Do meta descriptions affect rankings?
No. Google has said the meta description is not a ranking factor. It can still be used as the snippet, which influences whether people click your result. Treat it as advertising copy for the page, and write it for readers first.
Why does Google show a different title or description?
Google rewrites titles and snippets when it believes another version describes the page better for the query. Vague, stuffed or duplicated tags are rewritten most often. Clear, accurate tags that match the page content are more likely to be shown as written.
How can I tell if a page has noindex?
Run the page through the checker. It reads both the robots meta tag and the X-Robots-Tag HTTP header, which is easy to miss in the page source. If either contains noindex, remove it, republish, and request reindexing in Search Console.
