The search for an ideal title length for SEO usually ends at a plugin’s progress bar turning green. That bar measures something real, which is roughly how much of the title will fit on a typical screen. It does not measure what Google ranks, and it does not measure what Google shows, because Google may not show your title at all. Length is the smallest of three questions. The bigger two are whether the title is accurate and whether it is distinct from every other title on your site.
Google sets no limit, but it truncates
Google’s documentation on title links is clear: “While there’s no limit on how long a <title> element can be, the title link is truncated … typically to fit the device width.” A long title is not an error and is not penalised. It simply loses its end on screen, replaced by an ellipsis.
That makes the visible length a moving target. A title that shows in full on a wide desktop result may be cut on a phone, and the reverse is never true. The practical point is about order, not count: whatever matters most must sit at the start, where every device shows it.
The <title> element itself is simple, one line in the head of the page:
Words beyond the cut are not invisible to Google. They are still part of the element. They are just invisible to the searcher deciding whether to click, which is the only place length really bites.
What the 40–60 character data shows
The number most people quote comes from Backlinko’s study of Google click-through rates, by Brian Dean, updated in April 2025. Across 4 million search results, title tags between 40 and 60 characters had the highest click-through rate, 8.9% better than titles outside that range.
That is a useful finding, and it is easy to over-read. It is a correlation from one dataset. It does not show that trimming a 70-character title to 55 will lift its clicks by 8.9%, because the titles in the range may differ from the others in many ways besides length: topic, intent, position, brand. It tells you where well-performing titles tend to sit, not why.
| Claim | Source | How firm it is |
|---|---|---|
No limit on <title> length | Google documentation | Stated policy |
| Title link truncated to fit device width | Google documentation | Stated policy |
| Google may generate a different title link | Google documentation | Stated policy |
| 40–60 characters had the highest CTR | Backlinko, 4 million results | Correlation, one dataset |
| 8.9% better CTR inside that range | Backlinko, 4 million results | Correlation, one dataset |
Read the table top to bottom and the hierarchy is plain. What Google states is fixed. What the study found is a sensible default to start from, not a constraint to obey.
When Google rewrites your title
Length is not the only reason a title you wrote never appears. Google says it may generate a different title link from other sources on the page: the main visual title, the <h1>, the og:title, other prominent text, anchor text pointing at the page, or WebSite structured data.
Its documentation lists the situations that make a rewrite more likely. The title is inaccurate, or obsolete, such as a year that has passed. It is in a different language or script from the page. It is boilerplate repeated across many pages. Or several headings compete, so it is unclear which one is the real title. None of those is about length, and all of them are within your control.
The fix is consistency. When the <title>, the H1 and the visible headline say the same thing in slightly different lengths, Google has no reason to look elsewhere. When they disagree, it picks one, and it may not be the one you wanted. This page is an example: the title is short, the H1 is longer and carries the full question, and both describe the same article.
An ideal title length for SEO is a range, not a number
Put the evidence together and the honest answer is a working range plus three habits. The range comes from Backlinko’s data and from what fits on common screens. The habits come from Google’s own explanation of when it rewrites.
- Front-load the subject. The keyword and the specific promise go first, where truncation cannot reach them.
- Drop boilerplate. A long site-name suffix repeated on every page is exactly the pattern Google says it may replace.
- Keep the title and H1 aligned. Different lengths are fine; different meanings invite a rewrite.
- Remove dates that will expire. An obsolete year is a listed reason for Google to generate its own title.
Within that, 40 to 60 characters is a reasonable place to aim, because it covers most headlines that say one clear thing. If your title needs 70 characters to be accurate, accuracy wins. If it reaches 60 by padding, cut the padding.
Measuring whether a title change worked
The only test that matters is your own click-through rate. Change a title, wait, and compare clicks and impressions for the same queries in Search Console. Expect noise: rankings move, seasons shift, and SERP features above you change how many people scroll down. Our CTR by position post covers what a normal rate looks like at each rank, and SERP features explains why two pages at the same position can earn very different click shares.
There is a limitation here too. Search Console shows clicks and impressions, but not which title link a searcher actually saw. If Google rewrote the title for some queries, your test is partly measuring Google’s version. Search the main queries yourself before concluding anything.
Titles and descriptions are written together and judged together. The companion piece on meta description length applies the same logic to snippets: Google sets no limit there either, truncates by device, and replaces what you wrote when the page says it better. For the rest of the on-page basics, our technical SEO checklist puts titles in context with the checks that sit around them. Treat length as the last thing you tune, not the first, and a well-made title rarely needs more than a light trim.
Frequently asked questions
Is there a maximum title length for Google?
No. Google says there is no limit on how long a title element can be. The title link is truncated as needed, typically to fit the device width.
What title length gets the most clicks?
In Backlinko’s study of 4 million results, titles of 40 to 60 characters had the highest click-through rate, 8.9% better than titles outside that range. It is a correlation from one dataset.
Why did Google change my title?
Google may generate a title link from the H1, og:title, prominent text or anchor text when the title is inaccurate, obsolete, in the wrong language, boilerplate, or competing with other headings.
Should the title and H1 be identical?
They do not need to be identical, but they should describe the same thing. Conflicting headings are one of the reasons Google rewrites titles.
The takeaway There is no ideal title length, only a sensible range. Lead with the subject, cut boilerplate, keep the title and H1 aligned, and judge changes by your own clicks.
