SERP snippet preview

Short answer: type your title tag, meta description and URL above. The preview draws a Google-style result for desktop and mobile, measures each line in pixels, and marks where the text would probably be cut. Aim for a title under about 600 px and a description under about 920 px on desktop.

What this SERP snippet preview does

Your title tag and meta description are the first thing searchers read about your page, and often the only thing. The SERP snippet preview shows how they'll look as a Google result before you publish: on desktop and mobile, with the matching keyword bolded and text cut where it would probably be truncated.

Most length checkers count characters. Google doesn't. It truncates by how wide the text is in pixels, so "WWWW" takes far more room than "iiii". This tool measures your text in the font and size Google results have used, so the cut-off follows the real width of your words rather than a character count.

Title and description length guidelines

These are estimates, not Google rules. Google doesn't publish a limit. Its documentation says title links are truncated to fit the device and may be generated from other text on the page (Google Search Central). The pixel figures come from measuring live results and shift when Google changes its layout.

Why Google rewrites titles and descriptions

Google may replace your title with text from your headings, anchor text pointing to the page, or other content, especially when the title is:

• Too long or stuffed with keywords;
• Boilerplate, the same pattern on every page ("Home | Brand");
• Missing or vague, like "Untitled" or "Page 2";
• Out of step with the page: a title promising something the page doesn't cover.

Descriptions get rewritten even more often, because Google picks whichever text from the page best matches each search. You can't stop that, but a specific, accurate description is used more often than a generic one.

Writing titles that fit and get clicked

1. Lead with the topic. The first words carry the most weight for readers scanning results, and survive truncation.
2. Put the brand last, or drop it if the title is tight; Google often shows the site name separately above the title.
3. Be specific: "(2026)", "Free", "5 steps" or a number earns attention when it's true.
4. One page, one unique title. Duplicates across pages are a common reason Google rewrites them.
5. Check the mobile preview. Many searches happen on phones, where titles wrap differently.

Writing descriptions that earn the click

• Answer "why click this one?" in the first sentence.
• Include the main keyword naturally; Google bolds matches.
• Keep the core message within ~120 characters so mobile doesn't cut it.
• Write a unique description for each important page rather than a site-wide default.

A worked example

The form starts with this page's own title and description filled in, so you can see a passing result straight away. Now try the classic over-long title: Best Running Shoes for Women 2026 | Top 25 Picks Reviewed by Experts | ShoeStore. The title bar turns red, the message says how many pixels too wide it is, and the desktop preview cuts it after "Reviewed by" or so with " ...". Move the brand off the end and drop "Reviewed by Experts" and it fits again. Type "running shoes" in the keyword box and both words are bolded in the description, the way Google bolds matches.

What it doesn't do

• It doesn't fetch your live page or look up how Google currently shows it. Search the page on Google for that.
• It can't predict a rewrite. If Google decides your title doesn't fit the query, it may show different text no matter how well the length fits.
• Mobile titles aren't truncated in the preview, only wrapped, because Google shows more title text on phones and the cut point varies by screen.
• It doesn't draw rich results (stars, prices, FAQ dropdowns, sitelinks) or the favicon. The round icon is a placeholder letter.
• Bulk mode checks titles only, not descriptions.

What the tips mean

• "Title is ~N px too wide for desktop." Over the 600 px estimate. Cut words from the end, or move the important ones to the front so the cut lands on less useful text.
• "Title is short." Under 25 characters. Not an error, just room you aren't using.
• "Description will be cut on desktop." Over about 920 px.
• "The keyword isn't in the title." The check looks for the first word of your keyword only.
• "A word repeats three or more times…" Repetition reads as stuffing and is one of the patterns Google says can trigger a rewrite.

Bulk mode

Auditing a whole site? Export titles from your crawler or CMS, paste them into Bulk titles, and every title is measured at once, with the ones that will be cut flagged. Sort your fixes by the pages that matter most.
