Frequently Asked Questions

Learn how Google displays search result snippets and best practices for title tags and meta descriptions.

How many characters should a title tag be for Google?

Google typically displays up to 600 pixels of a title tag on desktop search results, which is approximately 50 to 60 characters. On mobile devices, titles can wrap across two to three lines (up to 70–80 characters) before truncating.

Why does Google cut off titles by pixels rather than character count?

Google renders search snippets using proportional fonts (such as Arial and Roboto). Wide characters like 'W' and 'M' consume significantly more horizontal pixels than narrow characters like 'I' or 'l'. A 55-character title composed of wide letters might truncate, whereas a 65-character title with narrow letters might fit completely.

What is the optimal length for a meta description?

The recommended meta description length is 120 to 160 characters (up to ~960 pixels on desktop). On mobile devices, Google often truncates descriptions after approximately 120–130 characters. Keeping your primary value proposition and call to action within the first 120 characters ensures it is visible everywhere.

How does keyword bolding work in Google search results?

When a user searches for a term, Google bolds exact and closely matching words in the search result title, URL breadcrumb, and meta description. Bolded words take up slightly more pixel width, which can cause snippets near the limit to truncate earlier.

Why does Google sometimes change or rewrite my title tag?

Google may rewrite title tags if it believes the existing title is too long, stuffed with keywords, boilerplate, or doesn't accurately match the search query intent. To prevent rewrites, keep titles concise, relevant, and front-loaded with your primary topic.

Does adding a publication date affect snippet length?

Yes. For blog posts, articles, and news content, Google frequently prepends the publication or updated date (e.g. 'Jan 15, 2026 — ') to the meta description, reducing the characters available for your descriptive text by roughly 15 characters.
