Preview how a title and meta description look in Google.
The SERP snippet preview shows how a page title, URL and meta description will look in Google's search results, on desktop and on mobile. It measures the title and the description in pixels, the way Google does, and cuts them where Google would.
A snippet is your page's ad in the search results: a clear title with the main keyword and a description that answers the searcher's question get more clicks, even without a better ranking.
See both layouts side by side.
Titles are cut at about 600 pixels, not at a fixed number of characters.
Green when the title and description have a good length, red when they're too short or too long.
Every change is shown instantly, in your browser.
About 50 to 60 characters, or up to 600 pixels. Longer titles are cut with an ellipsis.
Between 120 and 160 characters works best. Google may still rewrite it to match the search.
Google rewrites snippets when it thinks another text on the page answers the search better. A clear, accurate title and description reduce rewrites.
Not directly, but a good description improves the click-through rate, which brings more visitors.
