Free SERP Simulator & Google Snippet Generator ...
Free SERP simulator: preview your title and meta description as Google shows them on desktop and mobile, with pixel-width checks ...
Measured in pixels in Arial. Google publishes no fixed limits; these are close approximations, and Google may still rewrite your title or snippet.
- The title is wider than desktop results show. The end will be cut — put the words that matter first.
- The description is longer than Google usually shows. The end will be cut.
- The title contains "serp simulator".
- The description contains your keyword, so Google can bold it.
Three steps to a snippet people click
1. Paste your tags
Your title tag, meta description and the page URL. Add the keyword you want the page found for.
2. Check both devices
Switch between desktop and mobile. If a line ends in "...", the words after the cut are lost.
3. Fix and copy
Move the important words to the front, work through the checks, then copy the HTML tags into your page.
Google cuts titles by width, not by characters
A character count is only a guess. Letters take different amounts of space: a title full of W and M runs out of room far sooner than one full of i and l, so two 55-character titles can end in very different places. That is why this simulator measures each line in pixels, in the font Google uses for results, and cuts it at a word boundary the way Google does.
The limits it uses — about 600 pixels for a desktop title and about 990 pixels for a desktop description — are approximations. Google does not publish them and adjusts its layout from time to time. Treat a line that is close to the limit as at risk, and keep your most important words at the start.
When Google rewrites your title or snippet
Your title tag is Google's main source for the blue link, but not its only one. According to Google's documentation on title links, it can also use the page's main heading, other prominent text, anchor text and links pointing to the page. It is most likely to do that when a title is empty or nearly so, repeats the same boilerplate across many pages, is stuffed with keywords, or no longer matches the page.
Descriptions work the same way. Google's snippet documentation says it uses the meta description when that describes the page better than text taken from the page itself, and it often picks different text for different searches. A clear, specific description for each page gives you the best chance of it being used.
Rich results are narrower than many previews suggest. Review stars need an eligible page type and are not shown for reviews a business publishes about itself. FAQ dropdowns are gone altogether: Google limited them to government and health sites in August 2023 and stopped showing them in Search on 7 May 2026. FAQPage markup can stay on your pages, but it no longer earns a rich result. That is why this tool offers stars as an option with a warning, and no FAQ dropdowns.
SERP simulator questions, answered
What is a SERP simulator?
A SERP simulator shows how a page's title tag, meta description and URL are likely to look in Google's search results before you publish them. This one measures each line in pixels, shows where Google would cut it on desktop and mobile, and bolds your keyword the way Google bolds the words someone searched for.
How long can a title tag be in Google?
Google has no character limit; it cuts titles by width. On desktop, titles wider than roughly 600 pixels are usually cut with "...", which is about 50 to 60 characters depending on the letters. Put the words that matter first so a cut costs you nothing.
How long should a meta description be?
Google shows about two lines on desktop, which works out to around 990 pixels or roughly 150 to 160 characters. Longer descriptions are cut. Google can also ignore your description and show text from the page when that matches the search better.
Why does Google show a different title from mine?
Google writes its own title link when it thinks the title tag does not describe the page well: titles that are empty, stuffed with keywords, the same across many pages, or out of date. It may use the page's main heading, other prominent text or links pointing to the page instead.
Can I get review stars or FAQ dropdowns in my result?
Review stars, only in some cases: they appear for certain page types, such as products, recipes and software, and not for reviews a business publishes about itself. FAQ dropdowns, no: Google stopped showing FAQ rich results in Search on 7 May 2026. FAQPage markup can stay on your pages, but it no longer earns a rich result.
Is anything I type stored or sent anywhere?
No. The simulator runs entirely in your browser. Nothing you type is sent to SearchPrex or anyone else. The share link puts your title and description in the link itself, so only share it where you are happy for them to be seen.
