SERP Simulator

Why measure in pixels

Search results are laid out in a fixed width, so whether a title fits depends on how wide its letters are, not how many there are. A title full of narrow letters such as “i” and “l” can be seventy characters long and still fit; one with many capitals and “W”s can be cut at fifty. Character limits are a rule of thumb. Measuring the rendered width is closer to what actually happens on the page.

This simulator draws your text with the same font family and size Google uses for results and measures it in your browser. The desktop title is measured at 20 pixel Arial against a limit of about 600 pixels. The description is measured at 14 pixel Arial against about 920 pixels, which is roughly two lines. On mobile, titles wrap onto as many as three lines instead of being cut on one, and descriptions get less horizontal room. These figures are approximations taken from the current layout; Google does not publish them and adjusts its design from time to time.

How truncation works

When text is too wide, Google usually stops at the last whole word that fits and adds an ellipsis. The previews do the same, so you can see whether the cut lands somewhere harmless or removes the most important part of the message. If it does, move that part earlier rather than squeezing in more words.

Google often rewrites snippets

Your title element and meta description are suggestions. Google may show a different title, built from a heading, link text pointing to the page or other prominent text, when it judges that to describe the page better for a particular query. Descriptions are rewritten even more often, usually by quoting the part of the page that matches the search. Google’s documentation lists the common causes: titles that are missing, very long, stuffed with keywords, the same across many pages, or out of date.

The best defence is a title that is specific, accurate and unique to the page, and a description that summarises what the page actually offers. Neither guarantees that Google will use them, which is why this tool calls itself a preview.

Writing a good title

• Put the words that tell someone they have found the right page near the start.
• Describe this page, not the whole site. Every page needs its own title.
• Use your brand once, usually at the end, separated by a dash or a pipe. Google may also show your site name separately above the result.
• Avoid writing in capitals and repeating the same keyword. Both read as spam and are likely to be rewritten.

Writing a useful description

A description is a short pitch to someone who has already searched for the topic. Say what they will get, who it is for and anything that sets it apart, in plain language. Aim for one or two sentences that make sense even if the end is cut off. When the searched words appear in the description, Google usually shows them in bold, which is why the simulator can highlight a keyword you enter.

The URL line

Above the title, Google shows the site name, an icon and a breadcrumb-style URL such as example.com › blog › post. It is built from the URL path or from breadcrumb structured data on the page. Short, readable paths produce a cleaner line. You can override the breadcrumb here to see how structured breadcrumbs would look.
