Google rewriting title tags happens when its automated system swaps your page's title for other text, often your main heading. This happens because the title is empty, outdated, stuffed with keywords, repeated across pages, or doesn't match the page. If your title tag isn't showing in Google search results, the reason is usually on that list.
What Google uses to create your title link
Google calls the clickable headline in a search result a "title link." According to Google Search Central, creating that title link "is completely automated." It draws on both your page content and references to your page elsewhere on the web. Google looks at several places for this text: the <title> element, the main visible title, and heading elements such as <h1>. It also checks the og:title tag, other large or prominent text, and other page text. Google looks at anchor text on the page too, along with text in links pointing to the page and WebSite structured data. Google also says it "can't manually change title links for individual sites." So there is no support request that gets your exact title tag restored.
Common reasons Google replaces a title tag
On August 24, 2021, the Google Search Central Blog by Danny Sullivan announced a change to how Google creates page titles. Titles generally no longer change based on the search query. Google makes more use of text people can see, like the main headline. Google pointed to titles that were too long or "stuffed" with keywords as reasons it looks beyond the title tag. It also pointed to titles that were missing, or boilerplate like "Home" or "Untitled."
Google's current list of triggers, as described in its documentation, is similar. It includes half-empty titles such as "| Site Name" with nothing else attached. It includes obsolete titles that still show last year's date. It also includes titles that are inaccurate. It also includes micro-boilerplate where many pages share the same title, and no clear main title when several headings look equally prominent. Google's list also covers a mismatch between the page's language or script and the title, and a website name that repeats. When several headings on a page look equally large, Google "may use the first heading" as the title link. It uses this instead of your title tag.
After feedback, Google followed up on September 17, 2021, in another Search Central Blog post. Google said title elements were used "around 87% of the time, rather than around 80% before." That figure is several years old now and reflects a moment after the 2021 change, so treat it as background.
There's no official length limit
Google Search Central states plainly that "there's no limit on how long a <title> element can be." The title link itself gets truncated as needed, typically to fit the width of the device screen. Google advises writing a title that is descriptive and concise. Avoid vague titles like "Home" or "Profile," skip keyword stuffing, and don't repeat the same boilerplate title across a group of pages. If you add a brand name, keep it short. Place it at the start or end after a hyphen, colon, or pipe.
How to check and fix your titles
Start by searching site:yourdomain.com and comparing the titles Google shows against the title tags on your pages. For each mismatch, check it against the trigger list above. Is the title empty, old, stuffed, repeated, or missing a clear main heading? Write one plain title per page that matches its <h1>. Follow a pattern like service plus city or topic, then your business name. Fix leftover template issues such as empty titles, old years still showing, or one title copied across many pages. Give every page a single heading that is clearly the largest and most prominent piece of text.
Google builds the snippet beneath your title mainly from page content too. Google Search Central notes that your meta description gets used only when it describes the page better than the on-page text does. The snippet shown can also differ between searches. Writing a unique meta description for each important page is still a reasonable habit, even without a guarantee it will always appear.

How long changes take to show up
Once you edit a title tag or heading, Google needs to recrawl the page. Only after that can the new title link appear in results. Google Search Central says this "may take a few days to a few weeks." So give your changes time before deciding whether they worked. Also note that if robots.txt blocks Google from a page, Google can still index it. It can also build a title from off-page text, like anchor text from other websites linking to it. This is another reason titles sometimes look unfamiliar.
Frequently asked questions
Why is Google showing a different title for my page?
Google's automated system looks at your title tag, headings, and other page text. It then builds the title link that fits the result best. It swaps in a different title when the original is empty, outdated, stuffed with keywords, or repeated across many pages. When that happens, Google often pulls from the page's main heading instead.
How long should a title tag be?
Google says there's no limit on how long a title element can be. The display gets truncated as needed to fit the device screen. So aim for a title that is descriptive and concise and skip the search for an exact character count.
Can I make Google use my title tag?
There is no guarantee. Google has said it "can't manually change title links for individual sites," so a one-off fix request isn't an option. Fixing the issues on Google's list, such as empty, outdated, or repeated titles, gives your title tag a better chance of being used as written.
How long until Google shows my new title?
Google needs to recrawl your page after you make a change. That process "may take a few days to a few weeks." Give your changes that time before judging whether they worked.
Does Google use my meta description?
Sometimes. Google builds the snippet beneath your title mainly from the page's own content. It uses your meta description only when it describes the page better than that on-page text. Results can also differ between searches, so a unique description for each page is still worth writing.
Google rewriting title tags usually traces back to a title that was empty, outdated, stuffed, repeated, or a poor match for the page. Working through that checklist, and giving each page one clear title tag and one clear heading, gives your title tag a better chance of being used as written.
