Many site owners still believe that whatever they type into the title tag is exactly what Google shows in search results. For years that was mostly true. Then, in mid-August 2021, people started opening Google and finding their carefully written titles replaced with something else: an H1, a bit of anchor text, or a phrase they did not even remember writing.
That was the start of what SEOs now call the title link update. Google switched to a new system for generating the clickable headline of each result. It was not a ranking update in the usual sense. Your position did not have to change for your title to change. But because the title is the first thing a searcher reads, it affected clicks, branding and trust in a very visible way.
Let me explain what happened, what Google said, what the data showed, and how to write titles that Google keeps today. If you want to see where this sits among other changes that year, our timeline of every Google algorithm update puts it in context.
The August 2021 title change at a glance
| Item | Details |
|---|---|
| When SEOs noticed | Around 16–17 August 2021 |
| Google announcement | Search Central blog post, August 2021 ("An update to how we generate web page titles") |
| Follow-up | September 2021 post with more detail and refinements |
| Type | Search results display change (not a core ranking update) |
| Confirmed by Google? | Yes |
| What changed | Google relied less on the HTML title tag and more on other on-page text, such as H1s |
| Title tag use | About 80% at launch, around 87% after September refinements (per Google, as reported by Wordtracker) |
| Who was affected | Sites with long, empty, outdated, repetitive or keyword-stuffed titles most of all |
What SEOs noticed in the third week of August
The first reports came in fast. According to Search Engine Journal's coverage, SEOs started noticing the rewrites on 16 August 2021. These were not the small tweaks people were used to, such as Google adding a brand name at the end. Whole titles were being swapped out.
The examples people shared fell into a few patterns:
- H1 text used instead of the title tag. This was the most common one.
- Anchor text from an internal link. Lily Ray spotted an article whose search title came from the text of a link pointing to it from elsewhere on the site.
- Dates pulled from the URL. Mayank Parmar saw a date from the URL added to the start of a title.
- Text from a different page on the same site. Brodie Clark found cases like this, and noted that rewritten titles tended to be shorter.
Google has always reserved the right to change titles. What was new was the scale. Pages with perfectly reasonable title tags were suddenly showing something else, and many site owners had spent years treating the title tag as the one element they fully controlled.
How Google explained the new title system
Google published a post on its Search Central blog in August 2021 titled "An update to how we generate web page titles." In plain words, it said it had introduced a new system for producing titles that, in its view, better described what a page was about. The system looked at the main visual title on the page, headings, and other prominent text, not just the HTML title element.
The reasoning was simple. Some title tags are poor descriptions of a page. They are too long, stuffed with keywords, empty apart from the brand name, or left over from a template. Google wanted the headline in its results to describe the page well, even when the site owner's title tag did not.
The problem was that the system also rewrote plenty of good titles, and sometimes made them worse. A long but accurate title might be replaced with a short H1 that lost the key detail, or a product page might show a generic category heading.
The September 2021 refinements and the 87% figure
After a few weeks of complaints and examples, Google published a follow-up in September 2021: "More information on how Google generates titles for web page results." It said it had adjusted the system based on feedback, and gave a number for how often it now used the title tag.
“title elements are now used around 87% of the time, rather than around 80% before.”

Google also explained the specific situations where it was most likely to replace a title. According to Wordtracker's summary, these were four patterns: half-empty titles, obsolete titles, inaccurate titles and "microboilerplate" titles. I explain each one below, because they are still the best checklist you can use. Google also told site owners to keep writing good title elements and said the HTML title may come back once the issue is fixed.
Where Google gets a title link from
Later, Google started calling the result headline a title link, and it now documents the system in its title link guide on Search Central. That page lists the sources Google may use to generate one:
- The content of the
<title>element - The main visual title shown on the page
- Heading elements, such as
<h1> - The
og:titlemeta tag - Other large or prominently styled text
- Other text on the page
- Anchor text on the page
- Text in links that point to the page
WebSitestructured data
Notice how much of this list is outside the title tag. That is the real lesson of 2021. Google now treats your title tag as a strong suggestion, not an instruction. If your H1, your on-page headline and the links pointing at the page all describe the page in the same way, Google has little reason to pick something else.
If you are new to how titles and headings work together, our Learn SEO lessons on title tags and headings and page structure cover the basics. I also have a separate piece on when your title tag and H1 should differ.
The four title problems that trigger a rewrite
Google's documentation still lists the same problem types it described in 2021, plus a few more it added later. Here is how I would translate them into plain fixes.
| Problem | What it looks like | What Google may do | How to fix it |
|---|---|---|---|
| Half-empty title | "| Site Name" with no page description, often from a broken template | Fill the gap with text from headings or prominent text | Fix the template so every page outputs a real description |
| Obsolete title | "Best Running Shoes 2023" on a page updated for this year | Use the date from the visible headline instead | Update the title when you update the page, or drop the year |
| Inaccurate title | Title promises something the page does not deliver | Rewrite to match the actual content | Describe what is really on the page |
| Micro-boilerplate | Many pages share nearly identical titles, differing by one detail | Add the missing detail (for example a season number) from the page | Put the distinguishing detail in each title |
| No clear main title | Several headings carry equal visual weight | Use the first heading it finds | Make one headline clearly the main one |
| Language mismatch | Title in a different language or script from the page | Choose different text from the page | Write the title in the page's main language |
| Duplicated site name | Brand name in the title when a site name already shows | Drop the brand from the title link | Keep branding short; accept this one |
The obsolete-year problem is one I see all the time on blogs and comparison pages. If you add a year to your titles, read our guide to putting a year in title tags before you do it at scale.
What independent data showed about the rewrites
Google's 87% figure was an average across all of its results. Independent studies measured something narrower, and got a different picture.
In November 2021, Ahrefs published a title tag study of 953,276 pages that ranked in the top 10. Ahrefs found that Google rewrote 33.4% of the title tags in its sample and used them as written 66.6% of the time, well below Google's figure. A few other findings from that study stand out:
- When Google did not use the title tag, it took the title from the H1 in 50.76% of cases.
- Titles longer than 600 pixels were rewritten 46.12% of the time, up from 29.45% before the change.
- Pages whose title tags had not changed were 33% more likely to be rewritten in September 2021 than in June 2021, which shows the August system really did change behavior.
- 7.4% of top-ranking pages had no title tag at all.
Why the gap between 87% and 66.6%? I treat this as direction, not hard science. Google measured across every result it shows, including many simple pages with clean titles. Ahrefs looked only at top-10 pages for its keyword set, measured at one point in time. Different samples give different answers. The direction is the same, though: a meaningful share of titles get rewritten, and long titles get rewritten most.
Did title rewrites affect rankings?
This is the question I got most at the time. The short answer is no, not directly. Google said the change was about how titles are displayed, not how pages are ranked. Your title tag is still read and used for understanding the page, even when Google shows something different.
But clicks are a different story. If Google replaces "Emergency Plumber in Leeds – 24/7, No Call-Out Fee" with "Our Services," your position might not move but your click-through rate could fall. That is why it is worth checking. Here is a quick, hypothetical example to show the scale.
Example (hypothetical): a service page ranks third for a phrase with 4,000 monthly impressions. With the original title, it gets a 6% click-through rate, so about 240 clicks a month. After Google swaps the title for a vague H1, the click-through rate drops to 4%, which is 160 clicks. Same ranking, 80 fewer visits a month, all because of the headline.
This is why the title link update belongs on any list of search results changes that get mistaken for algorithm updates. Traffic can drop without your rankings moving at all.
How to check which of your titles Google is rewriting
There is no report in Search Console that flags rewritten titles. You have to check by hand or with a crawler. Here is how I would do it:
- Export your top 50 to 100 landing pages by clicks from the Search Console performance report.
- Crawl those URLs to collect the title tag and H1 for each one.
- Search Google for the main query each page ranks for (or use a
site:search with the page URL) and note the title Google shows. - Mark each page as "kept," "trimmed" (Google shortened it) or "replaced" (different text).
- For each replaced title, work out which of the problems in the table above applies.
- Fix the cause, not just the title tag. Often the H1 or template is the issue.
- Wait for Google to recrawl, then check again in two to four weeks.

Writing titles Google is likely to keep in 2026
Five years on, the advice is simple and has not changed much. Google's own title link documentation gives most of it. Here is my shortlist:
- Give every page a unique, descriptive title. Avoid vague labels like "Home" or "Services."
- Keep it concise. Long titles get cut or rewritten. Aim for roughly 50–60 characters for the part that matters.
- Match your H1. They do not have to be identical, but they should describe the same thing.
- Brand briefly. Put your brand at the start or end with a simple separator, such as a hyphen or pipe.
- Do not stuff keywords or repeat the same phrase.
- Keep dates current or leave them out.
- Make one headline clearly the main title on the page.
Google's title link rewrites are also a cousin of the old 2018 discussion about brackets in titles; our article on the "Brackets" core update of 2018 covers an earlier moment when titles were in the spotlight. For the rest of that year's changes, see our review of Google's 2021 algorithm updates.
Title links were not the last time Google changed what you see in results without touching rankings. In 2025, the removal of the num=100 parameter caused another "drop" that was really a reporting change; I cover it in why impressions fell when Google dropped num=100. And in 2023, Google started favoring first-hand content with its hidden gems ranking work.
Questions people ask about Google rewriting titles
Can I stop Google from rewriting my title?
No. There is no tag or setting that forces Google to use your title tag. The best you can do is remove the reasons it rewrites titles: make them accurate, concise, current and consistent with your H1.
Does Google still use my title tag for ranking if it shows a different title?
Google has said the title link change is about display. Your title tag is still part of how Google understands the page, so it is still worth writing well.
How long does it take for a fixed title to show?
It depends on how often Google recrawls the page. Busy pages may update within days. Quieter pages can take a few weeks. Requesting indexing in Search Console can speed this up a little.
Is it bad if Google only trims my title?
Not usually. Trimming long titles to fit the screen is normal. It becomes a problem only when the part that gets cut is the bit that makes people click.
Why does Google add my brand name to some titles and not others?
Google may add or remove a site name depending on whether one already shows in the result. Its documentation says a duplicated site name may be dropped from the title link.
Getting your title links back under control
In brief: the August 2021 change taught us that the title tag is a suggestion. Google picks the text it thinks best describes the page, and it looks at your H1, your visible headline and even links pointing to the page. Make all of those agree, keep titles short and honest, and Google will keep most of them.
