How to use the SERP preview
- Enter your page title, meta description and URL.
- Switch between desktop and mobile previews.
- Add a keyword to see it bolded, as Google does with words matching the search.
- Read the checklist: it measures the title in pixels, the description length, and whether the keyword appears in each.
Why pixels, not characters?
Google cuts titles by display width, not by a fixed number of characters. The title area is roughly 580–600 pixels wide on desktop. A title full of narrow letters (“i”, “l”, “t”) fits more characters than one with wide letters (“W”, “M”) or capitals. This tool measures your title with the font size Google uses, so you get a far more accurate warning than a simple character count. As a rule of thumb, 50–60 characters is usually safe.
Descriptions are cut at around 920 pixels on desktop (roughly 155–160 characters) and less on mobile (roughly 120 characters).
What makes a snippet get clicked
- Match the intent. If people search “free word counter”, say “free” in the title.
- Be specific. Numbers, years and concrete benefits (“in 2 minutes”, “no sign-up”) stand out.
- Lead with the keyword, but write for humans — titles that read like keyword lists get fewer clicks.
- Use a readable URL. Short, descriptive slugs look trustworthy. See our URL Slug Generator.
Google may rewrite your snippet
Google rewrites titles and descriptions when it thinks another text better matches the search — for example, if your title is too long, stuffed with keywords or doesn’t describe the page. Writing an accurate, concise title and description is the best way to keep control. Adding structured data with our Schema Generator can also make your result eligible for rich features such as review stars or breadcrumbs.
The preview is an approximation: Google’s layout changes, and real results can include site names, favicons, dates, sitelinks and rich results.
Frequently asked questions
How long should a Google title be?
Keep it under about 600 pixels — usually 50–60 characters. The preview measures the pixel width for you.
Why does Google show a different title than mine?
Google rewrites titles that are too long, repetitive or don’t match the page content well. Clear, accurate titles are rewritten less often.
Does the meta description affect ranking?
Not directly, but a compelling description improves click-through rate, which brings more visitors from the same ranking.
Is this exactly how Google will show my page?
It is a close approximation. Real results can include extra elements such as the site name, favicon, date and rich results.
