Description Length FAQ
What is the character limit for meta descriptions?
While there's no hard limit, Google typically truncates descriptions after 155-160 characters on desktop and about 120 on mobile.
Why is pixel width more important than character count?
Since different characters have different widths, a pixel-based limit is much more accurate for ensuring your full message is visible.
Should I make my meta descriptions as long as possible?
Not necessarily. Focus on providing a clear value proposition and a call-to-action within the first 120-130 characters for best results.
Does a short meta description hurt SEO?
No, but it's a missed opportunity to provide more context and keywords to the user before they click.
Can this tool check descriptions from my live website?
Yes! Use the 'Import from URL' tab to instantly audit any existing page on your site.
How do I optimize descriptions for mobile?
Keep your most important information at the beginning, as mobile devices often truncate snippets sooner than desktop browsers.
