On-Page SEO Snippet Optimizer

It's a free tool that shows how your page will look in Google's search results before you publish. You enter a target keyword, page title, URL slug, and meta description, and it renders a live Google preview, checks each field against on-page SEO best practices, and grades the result out of 100.

Google truncates snippets by pixel width, not character count — a title full of wide letters like W and M gets cut off sooner than one made of narrow letters like i and l. Measuring the actual rendered width (about 600px for titles and 920px for descriptions) tells you far more accurately whether your snippet will be cut off with an ellipsis.

Keep your title under roughly 600 pixels (about 50–60 characters) so it isn't truncated, and your meta description under roughly 920 pixels (about 140–160 characters). The fill bar under each field turns green when you're within the safe range, orange when it's too short, and red once you exceed the limit.

Not always. Google frequently rewrites titles and pulls description text from elsewhere on the page based on the searcher's query, and it may add dates, sitelinks, or rich results. This tool shows an accurate approximation of the standard snippet so you can optimize what you control — treat it as a strong guide, not a guarantee.

The score combines the individual checks across your title, URL slug, and meta description — keyword placement, pixel length, use of numbers or power words, clean hyphenation, a call-to-action, active voice, and more. Each check is weighted by importance. Checks that need a target keyword are skipped from the total until you add one, so the grade stays fair.

Yes. Several checks look at whether your keyword appears — and how early — in the title, slug, and description, since front-loaded keywords carry more weight and survive truncation. Until you enter a keyword, those checks are set aside and don't count against your score.

No. The entire tool runs in your browser. Nothing you type is sent to a server, stored, or shared — refresh the page and it's gone. There's no sign-up and no account required.

Google lays out and truncates snippets differently on desktop and mobile. The toggle above the preview lets you check both — the mobile view stacks the logo and search bar and shows the narrower result card that phone users actually see.
