- Google shortens titles and descriptions by pixel width, not by character count.
- Keep titles under about 600px (usually 50 to 60 characters) with the main keyword near the start.
- Keep descriptions under about 920px on desktop, and put the key point in the first 680px for mobile.
- Google may rewrite either one, so make both match what the page is really about.
What a SERP preview tool does
A SERP preview tool shows how a page is likely to look in Google's search results. SERP stands for search engine results page. You add a title, a meta description and a URL, and the tool draws the result the way a searcher would see it, including where Google is likely to cut the text short.
That matters because your search result is your first pitch. Ranking gets the page seen. The title and description decide whether people click it, or the result above and below it.
How to use this SERP preview tool
- Add your page title. This is the text inside your page's
<title>tag, often set as the SEO title in your CMS. - Add your meta description. The short summary set in your SEO plugin or CMS.
- Add the page URL to see the site name and breadcrumb Google shows above the title.
- Add a focus keyword if you have one. The tool checks it appears in both fields and shows the words Google may bold.
- Switch between desktop and mobile, fix anything marked in red, then copy the finished HTML tags.
Title and description length: pixels, not characters
Google doesn't stop a title at a set number of characters. It stops when the text runs out of room, and room is measured in pixels. A capital W takes up far more space than a lowercase i, so two titles with the same number of characters can fit very differently.
| Element | Width this tool checks | Rough character guide |
|---|---|---|
| Title tag | About 600px | 50 to 60 characters |
| Meta description, desktop | About 920px | 150 to 160 characters |
| Meta description, mobile | About 680px | 110 to 120 characters |
Google doesn't publish these limits and adjusts its layout from time to time, so treat them as safe targets rather than hard rules. A few pixels over is fine as long as the words that matter come first.
How to write a title tag that earns the click
- Lead with the topic. Put the main keyword, or the phrase people actually search, in the first few words so it survives any shortening.
- Say what people get. A free template, a price, a comparison, a step-by-step guide. Specific beats clever.
- Give every page its own title. Unique titles help Google and searchers tell your pages apart.
- Add your brand at the end when there's room. It builds recognition, and it's the first thing to drop when space is tight.
- Match the page. Google is more likely to keep your title when it clearly describes what's on the page and matches your main heading.
How to write a meta description that gets clicks
The meta description is the short summary under the title. Google has said it doesn't use descriptions to rank pages, but a clear one helps the right people pick your result over the others.
- Answer the search. Say what the page covers and who it's for in the first sentence.
- Put the important part first, because mobile shows less of it.
- Use the keyword naturally. Google often bolds words that match the search, which helps your result stand out.
- Close with a reason to click, like free, no signup, examples included or a clear next step.
Why Google sometimes shows a different title or description
Google treats your title and meta description as strong suggestions. For titles, it can use your main heading, link text pointing to the page or other prominent text instead, especially when a title is very long, repeats the same keyword or doesn't match the page. For descriptions, it often shows a passage from the page that fits the specific search better.
You can't turn this off, but you can make it less likely. Keep the title within the widths above, make it match your H1, write it for people rather than for keywords, and give every page a description of its own.
How to check your new titles are working
The real test is click-through rate (CTR): the share of people who saw your page in search and clicked it. Google Search Console shows impressions, clicks and CTR for every page and every query.
Start with pages that get plenty of impressions but a low CTR for their position. Those are the pages where a better title and description can win more clicks without moving up a single place. Rewrite them, give Google a few weeks to pick up the change, then compare the same date ranges.
Connect Search Console to Analyse8 and ask which pages get impressions but few clicks. You get the list, the queries behind each page and the next steps written for you.
