What is a title tag?
The title tag is the most-read sentence you will write about your webpage. It is the clickable blue headline in Google's search results. The text in your browser tab when the page is open. The default bookmark name. The heading social platforms display when a URL gets shared.
It is also one of the strongest on-page ranking signals. And consistently one of the most poorly executed elements across most websites, either too long, too vague, keyword-stuffed, or copied from the H1 without thought.
Go deeper: why pixel width matters more than character count, and why mobile decides it now
Most title-tag advice still leads with a character count: "keep it under 60." That's a useful approximation, but it's not what Google is actually measuring. Google truncates based on pixel width, roughly 600 pixels on desktop, and different characters consume different amounts of space, a lowercase "i" costs far less width than a capital "W." Two titles at exactly 58 characters can render completely differently depending on which letters they're made of.
The more important shift: Google completed its move to 100% mobile-first indexing in July 2024, meaning the mobile rendering of your title, on a narrower screen with its own pixel budget, is the version that matters by default, not the desktop one. Shwetank Ojha's title-tag audits now check the mobile SERP preview first, since a title that renders cleanly on desktop can still truncate awkwardly on the surface Google actually indexes from.
Title tag vs. H1, clear this up first
A persistent source of confusion. The title tag appears in the SERP and browser tab, it convinces users to click before they visit. The H1 heading appears on the page itself, it orients users once they have arrived. These should target the same primary keyword with closely aligned phrasing, but they do not need to be identical.
How to write a title tag that earns clicks
- Under 60 characters: Google truncates at approximately 600 pixels. Anything cut off with "..." loses impact and reads as unfinished.
- Lead with the keyword: Google weights words that appear earlier in the title more heavily. Users reading left-to-right see the relevance confirmation immediately.
- Write for the human scanning 10 results in 15 seconds: Your title needs to immediately communicate relevance and create enough interest to earn the click.
- Brand name at the end where relevant: "Best CRM for Freelancers | YourBrand." For informational content, the term definition matters more than branding.
- Make every title unique: Duplicate title tags signal overlapping content to Google and split SEO authority between pages.
The rewrite problem
Google rewrites title tags in an estimated 30 to 50% of cases. This happens most often when the title is too long and gets truncated, the title does not closely match the actual page content, or a specific heading on the page is more relevant to the query variant that triggered the impression.
In practice, Google's rewrites are serviceable but rarely better than a well-written original. The more accurate, specific, and correctly-lengthed your title, the less often Google overrides it.
Go deeper: a rewritten title is diagnostic, not just an inconvenience
Most advice treats Google's title rewrites as something to simply tolerate. There's a better use for it: every rewrite is a signal about what Google thinks the page is actually about for that specific query, and it's free feedback you didn't have to ask for. Pull the "Performance" report in Search Console, filter to a page with a high rewrite rate, and compare what Google is substituting against your original. A consistent pattern, Google repeatedly pulling in a phrase from your H2s instead of your title, usually means that phrase deserves to be in the title tag itself, not buried two scroll-lengths down.
Frequently asked questions
What is the ideal title tag length?
Under 60 characters as a working rule. A slightly longer title that carries meaningfully more information may still be worth using, with awareness that it risks truncation. Google Search Console flags pages with titles that are too long or too short.
Should every page have a unique title tag?
Yes, without exception. Duplicate title tags signal overlapping content, split SEO authority, and create a confusing experience when two pages from the same domain appear in the SERP simultaneously.
What is the difference between a title tag and a page title?
They refer to the same element. "Title tag," "page title," and "meta title" all mean the HTML title element. Google Search Console's URL Inspection Tool shows you both the HTML title and what Google actually displays in search results.
Why does Google keep rewriting my title tag?
Usually one of three reasons: the title is too long and gets truncated, the title doesn't closely match what the page is actually about, or a different heading on the page matches the specific query variant better than your title does. Check which heading Google is substituting in, it usually tells you exactly what to fix.
Should my title tag look different on mobile than desktop?
The HTML title tag itself is the same for both, you don't write two versions. But since mobile-first indexing means Google primarily evaluates the mobile rendering, always preview how your title actually displays on a mobile SERP before publishing, not just the desktop view.
Is there a tool to check my title tag?
Yes. SERP preview tools (built into Yoast, RankMath, and several free standalone checkers) show exactly how a title renders by pixel width before you publish, which is more reliable than counting characters by hand. Google Search Console's Performance report, filtered to a single page, also shows what Google is actually displaying versus what you wrote, which catches rewrites a preview tool alone won't.
