Why Google Rewrites Titles and Meta Descriptions

You wrote a careful title tag and a meta description, and then Google shows something else: a heading from the middle of the page, your site name in the wrong place, or a sentence you never meant as a summary. That's not a bug. Google treats your title and description as strong suggestions, not as text it has to display.

Google's own documentation explains when and why it changes them. Here's what it says, how to tell a rewrite from simple truncation, and how to write titles and descriptions that Google is more likely to keep.

What Google actually shows

A search result has two main text parts:

The title link: the clickable headline. It usually comes from your <title> element, but not always.
The snippet: the one or two lines under it. It sometimes comes from your meta description, and often doesn't.

Both are generated automatically. Google's page on title links says plainly: "we can't manually change title links for individual sites." There's no setting that forces Google to use your exact title.

Where Google gets title links

According to that page, Google can draw on all of these when it builds a title link:

The content of the <title> element
The main visual title shown on the page
Heading elements such as <h1>
The og:title meta tag
Other large, prominent text
Other text on the page, and anchor text on the page
The text of links that point to the page
WebSite structured data

Your title element is the first source and usually the one used. The others become candidates when the title looks unhelpful for the page.

Why Google rewrites title tags

The documentation lists the common problems that lead Google to adjust a title link. Each one has a straightforward fix.

Half-empty titles

Part of the title is missing, as in <title>| Site Name</title>. This usually happens when a template fills in the page name from a field that was left blank. Google may build a better title from the page's heading. Fix the template so every page has a real title.

Obsolete titles

The same page is reused year after year, and the title still names an old year, like Google's example "2020 admissions criteria." Google may build a title that reflects the current content instead. Update titles when the content changes.

Inaccurate titles

The title doesn't describe what's on the page, for example a list of products the page doesn't actually carry. Write the title for the page you have, not the page you'd like to rank.

Micro-boilerplate

A group of pages share the same repeated title, such as every episode page of a TV show titled with only the show's name. Google may add the detail that tells them apart. Put the distinguishing part (episode, product model, city) in each title.

No clear main title

The page has several large, prominent headings and it isn't obvious which one is the main title. Make one heading clearly the main one, and keep it close to the title element.

Language or script mismatch

The title is in a different language or writing system from the page content. Match the title to the main content.

Keyword stuffing and long brand tails cause rewrites too. The documented best practices include "Avoid keyword stuffing," "Avoid repeated or boilerplate text in <title> elements," and "Brand your titles concisely."

Truncated isn't the same as rewritten

A title that ends in "…" hasn't necessarily been rewritten. Google says "there's no limit on how long a <title> element can be," but "the title link is truncated in Google Search results as needed, typically to fit the device width."

The cut is based on display width, not a character count, so a title full of wide letters like W and M runs out of room sooner than one with narrow letters. A practical target is to keep the important words in the first 50 to 60 characters. Our Meta Tag Generator previews the title at about 600 pixels for desktop and 520 for mobile and warns when it's likely to be shortened, and the Character Counter is handy for checking lengths while you draft. Treat both as guides, since Google publishes no fixed limit.

Why Google rewrites meta descriptions

Your meta description is even less certain to appear than your title, because of how snippets work. Google's page on controlling snippets says "snippets are primarily created from the page content itself," and that Google "sometimes uses the meta description HTML element if it might give users a more accurate description of the page than content taken directly from the page."

The key detail is that snippets depend on the search. Google says snippets are "designed to emphasize and preview the page content that best relates to a user's specific search," so "Google Search might show different snippets for different searches." Your description summarizes the whole page. Someone who searches for one specific detail will often see the paragraph that contains it instead.

So a replaced description isn't always a sign of a bad one. But some descriptions are far more likely to be skipped:

The same or similar description on many pages. Google notes that "identical or similar descriptions on every page of a site aren't helpful."
Keyword lists. Descriptions "comprised of long strings of keywords don't give users a clear idea of the page's content."
Descriptions that don't match the page. If the text promises something the page doesn't cover, page content wins.
Missing descriptions. With nothing to choose from, Google always builds the snippet from the page.

How to write titles Google tends to keep

Describe the page in plain words. "301 vs 302 Redirects Explained" beats "Redirects | SEO | Web | Guide."
Make every title unique, with the specific detail first.
Keep it close to the page's main heading. They don't have to be identical, but they should clearly be about the same thing.
Put the brand at the end and keep it short, such as "Page Name | Brand."
Front-load the important words so truncation only removes the less important part.
Update titles when content changes, especially years and prices.

How to write descriptions that get used

Write a short, specific summary of what the page offers, in a sentence or two a person would actually read.
Include the facts a searcher wants before clicking: what the page covers, what they can do there, who it's for.
Make each description unique. For large sites, Google says generating descriptions programmatically from page data "can be appropriate and are encouraged."
There's no length limit for the tag itself, but long descriptions are cut off. Aim for something that reads complete in roughly 150 to 160 characters.

The controls you do have

You can't force a title or description, but you can limit what Google shows:

<meta name="robots" content="nosnippet"> stops Google from showing a text snippet for the page.
max-snippet:[number] in the robots meta tag sets a maximum snippet length in characters.
The data-nosnippet attribute on an HTML element keeps that part of the page out of snippets.

These only restrict snippets. They don't make Google use your meta description, and there's no equivalent control for title links. Keeping a page out of search entirely is a different job, covered in robots.txt vs noindex.

Social networks are separate again. Facebook, LinkedIn and others read og:title and og:description and usually show them as written. If those previews look wrong, Link Preview Not Showing? walks through the fixes.

How to see what Google shows for your page

Search for your page with a few different queries: its main topic, a specific detail from the middle of the page, and your brand name. You'll often see one title but different snippets. If the title link differs from your <title>, compare it with the page's headings and the problems above; the replacement usually points straight at the cause. After you change a title, it can take a while for Google to recrawl the page and show the new version.

FAQ

Can I stop Google from rewriting my title?

No. There's no opt-out. Following Google's title best practices makes a rewrite less likely, but it's still Google's choice.

Why does Google show my H1 instead of my title tag?

Usually because the title is half-empty, boilerplate, stuffed with keywords or doesn't match the page, and the H1 describes the page better. Make the title a clear, specific description of the same topic as the H1.

How long should a meta description be?

Google sets no limit, but snippets are cut to fit the screen. Around 150 to 160 characters is a common guideline for a description that displays in full on many results.

Is it worth writing meta descriptions if Google replaces them?

Yes. Google still uses them when they describe the page well, especially for broad searches and brand searches, and some other services fall back on them when a page has no Open Graph description.
