Meta tag & SEO checker
Audit any page’s title, meta description, canonical, robots, and social-preview tags in one click, with length warnings for search and social.
Why meta tags still matter
Your title and meta description are your pitch in search results - they decide whether people click. Open Graph and Twitter tags control how your links look when shared. Clean, complete tags also help AI answer engines understand and cite your page. Once you have checked them, preview them with the SERP snippet preview.
Frequently asked questions
- What does the meta tag checker check?
- It fetches a page and reports its title and length, meta description and length, canonical URL, robots directive, language, viewport, H1 count, and the Open Graph and Twitter card tags used for social previews - with simple pass or warn indicators.
- What is a good title and meta description length?
- Aim for a title of roughly 15 to 60 characters and a meta description of about 50 to 160 characters. Longer titles and descriptions get truncated in search results. Use our SERP snippet preview to see exactly how they will look.
- Why does my page need a canonical tag and one H1?
- A self-referencing canonical tells search engines which URL is the primary version, preventing duplicate-content issues. A single, descriptive H1 helps engines and AI models understand the main topic of the page.
