Meta tag analyzer
Read every meta tag of a page the way search engines receive it. Check the title and description length in pixels, see whether the page can be indexed, and preview how it may look in search results.

What meta tags actually do
A handful of tags in the page head decide whether a page is indexed and how it looks in search. Most of the rest are for browsers and social apps.
The title is the one that counts most
It is the clickable headline in search results and a signal of what the page is about. Every page should have its own.
The description earns the click
It does not change rankings, but a good summary that matches the search can be shown as the snippet and makes people choose your result.
Robots and canonical decide indexing
A single noindex, in a tag or in the X-Robots-Tag header, keeps a page out of search. A canonical tells search engines which of several similar URLs to show.
Search engines read the HTML first
Tags that only appear after JavaScript runs may be picked up later or not at all. Put important tags in the HTML the server sends.
The tags that matter for search
What each one does, a sensible value, and whether Google uses it.
| Tag | What it does | Good value | Used by Google |
|---|---|---|---|
<title> |
The clickable headline in search results and the browser tab | About 50–60 characters, under ~600 px | Yes, as a strong signal |
meta description |
The snippet under the title, if Google uses it | About 120–160 characters | No, but it affects clicks |
meta robots |
Indexing rules such as noindex or nofollow | Usually not needed: the default is index, follow | Yes, noindex removes the page |
link rel="canonical" |
The preferred URL among duplicates | An absolute URL to the page itself | A strong hint |
meta viewport |
Makes the page fit phone screens | width=device-width, initial-scale=1 | Needed for mobile-friendly pages |
link rel="alternate" hreflang |
Versions of the page in other languages or regions | One per language, plus x-default | Helps show the right version |
meta keywords |
A list of keywords | Not needed | No, ignored by Google |
How this tool works
What happens between pressing Analyze and seeing the report.
You enter a URL
A full address such as https://example.com/page/. Our server checks it is public and connects to that address only.
The page is downloaded
Up to 2 MB of HTML, following up to 5 redirects. The X-Robots-Tag header is kept, because it can block indexing too.
Every tag is read
All meta tags, the title, canonical, hreflang, icons and structured data types, in page order, duplicates included.
Your browser judges them
Lengths in characters and approximate pixels, indexing rules, a search result preview and a full tag list to copy or download.
What this tool does, and what it doesn't
A plain list, so you know exactly what to expect.
This tool does
- List every meta and link tag, duplicates included
- Measure title and description in characters and pixels
- Combine meta robots, googlebot and X-Robots-Tag
- Compare the canonical with the final URL
- List hreflang versions and structured data types
- Show an approximate search result preview
This tool does not
- Run JavaScript or see tags added by scripts
- Check whether Google has indexed the page
- Predict the exact title Google will show
- Check robots.txt rules
- Read pages behind a login
- Store the URLs you check
Where your data goes
The URL you enter is downloaded by our server, which identifies itself as AllInOneToolsMetaTags and sends no cookies. The target site sees our server's IP address, not yours. The tags go straight to your browser and are not stored. A hashed, temporary copy of your IP address is used for rate limiting. Like any website, our server may keep normal access logs, as described in our privacy policy.

Why your results might look unexpected
The six surprises people run into most, and what each one means.
The page could not be fetched
It may block our server, need a login or answer with an error. Bot protection often answers 403 to data centre traffic.
Noindex on a page you want found
A plugin setting, a staging leftover or the X-Robots-Tag header. Remove it and request indexing in Search Console.
Two titles or two descriptions
A theme and an SEO plugin both print them. Google picks one unpredictably, so turn one of them off.
Canonical points to another page
Intended for duplicates, a mistake on unique pages. Check http versus https, www and trailing slashes.
Tags you added are missing
They may be added by JavaScript, which is not run here, or a cache is serving an older copy of the page.
Title shown differently in Google
Google rewrites long, repetitive or keyword-stuffed titles. Keep it unique, clear and within about 600 px.
Questions about meta tags
How long should a title tag be?
Google cuts titles by width, not by a fixed character count. On desktop, roughly 580 to 600 pixels fit, which is about 50 to 60 characters. This tool measures the approximate width in your browser. Put the main topic first so it survives if the end is cut.
How long should a meta description be?
Aim for about 120 to 160 characters, which fits most desktop results. Google often rewrites the snippet from page text when the description does not match the search, so treat it as a strong suggestion rather than a guarantee.
Why does Google show a different title or description?
Google can rewrite titles that are too long, stuffed with keywords or the same on many pages, and it picks snippet text that matches the search. A clear, unique title and description for each page make a rewrite less likely.
What does Not indexable mean here?
The page tells search engines not to index it, through a meta robots or googlebot tag with noindex or none, or an X-Robots-Tag HTTP header. A canonical pointing to another URL is shown separately, because it is a hint that Google may follow, not a block.
Do meta keywords still matter?
No. Google has ignored the meta keywords tag for ranking for many years, and Bing treats it as a weak signal at best. It does no harm, but it also shows competitors which keywords you target, so many sites remove it.
Why are tags missing that I can see in my browser?
This tool reads the HTML the server sends and does not run JavaScript. Tags added later by scripts, such as some single-page apps add, will not appear. A caching plugin or CDN may also serve an older copy of the page.
Is the URL I check stored?
No. Our server downloads the page, reads the tags and sends them straight to your browser without saving them. The target site sees our server, not you. A hashed, temporary copy of your IP address is used for rate limiting and expires within 24 hours. Like any website, our server may keep normal access logs, as described in our privacy policy.
