Title & Meta Description Checker
Measure your title and meta description in pixels and characters, and preview how they will look on Google on desktop and mobile.
This tool runs entirely in your browser. What you enter is not sent to a server, not saved and not stored in cookies.
The title tag and meta description are the first things people see about your site in search results. A good title raises the click-through rate; a cut-off or vague one can make even a top result invisible. This tool measures both at the width Google shows them.
How to use it
- Enter the page URL; the address and site name in the preview follow it.
- Write the title. Under each field you see the pixels left for desktop and mobile, live.
- Write the meta description and switch between the two tabs to see where it is cut on desktop and mobile.
- If a row turns red, shorten the words or move the most important ones to the front.
Frequently asked questions
How long should a title tag be?
Roughly 50–60 characters, but the real limit is width: about 580 pixels on desktop. Wide letters (M, W) fill it faster and narrow ones (i, l) slower, so character count alone is misleading.
How long should a meta description be?
About 920 pixels on desktop and 680 on mobile, roughly 150–160 and 110–120 characters. Mobile shows less, so put the main message in the first sentence.
Why does Google change my title?
If a title is very long, stuffed with keywords, does not describe the page or is the same on every page, Google may use the H1 or other text instead. A clear, unique and accurate title makes that less likely.
Does the meta description affect rankings?
It is not a direct ranking factor. It does affect click-through rate: a good description brings more visitors from the same position.
How are pixels measured?
Google uses Arial in search results. The tool uses Arial’s real width for every character, so each letter counts with its own width and the result is the same on every device.
Rather scan your whole site with an AI skill than check links one by one?
technical-seo-skill is an open-source skill I built that works like a technical SEO specialist inside your AI agent (Claude Code or Codex). It discovers every URL on your domain and subdomains, checks robots.txt, llms.txt and sitemaps, titles, descriptions, canonicals, H1s, hreflang and schema, finds broken internal links, orphan pages and oversized images, and hands you an Excel report with a prioritised task list.
Give the link to your AI
In Claude Code or Codex, paste a request like this and change the domain. The agent installs the skill and runs the audit.
Install the skill at https://github.com/AndacGuven/technical-seo-skill and run a technical SEO audit for https://example.com. Give me the Excel report and the most urgent fixes first.
Install it yourself
Clone the repository into your agent’s skills folder and restart the agent. Or download the v1.0.0-alpha release from GitHub’s Releases section and put SKILL.md and technical_seo_skill.py in the same folder.

Why pixels and not just characters?
Google cuts titles and descriptions by display width, not by character count. “WWW” takes far more room than “iii”, so two 60-character titles can end at very different points. This tool measures your text in the font Google uses and shows where it would be cut.
- Title: about 580 px on desktop (roughly 50–60 characters). Put the most important words first.
- Meta description: about 920 px on desktop and 680 px on mobile (roughly 150–160 characters). Write it as a reason to click, and make every page’s description unique.
- Google can replace both with text from the page. A clear, accurate title and description make that less likely.
