Short answer: keep your title under ~60 characters and put the keyword first. Write your meta description somewhere between 120 and 160 characters, and make it earn the click rather than just restate the title. Google rewrites descriptions fairly often — pulling whatever snippet it thinks fits the query better than what you wrote — so write for the times it doesn't get rewritten.
That's the whole thing. The rest of this post is the why behind those numbers, the failure modes, and what actually happens inside Google's UI when you get it wrong.
If you want the full picture of which meta tags matter and which are just noise, start at meta tags for SEO. This post zooms in on two specific ones.
Title tags: yes, this one actually matters for rankings
The <title> tag is a confirmed Google ranking factor. Not a "best practice," not a "nice to have" — an actual signal Google uses when deciding where to rank your page. It's also the clickable blue headline in search results, so it does double duty: ranking signal and click bait, in the most literal sense of that phrase.
A few things to get right.
The character limit (and why it's not actually characters)
You'll see "60 characters" everywhere, and it's a reasonable rule. The real limit, though, is pixel width — around 600px on desktop. Google truncates titles that exceed that, replacing the end with an ellipsis. The problem is different characters take up different widths.
An uppercase "W" eats more space than a lowercase "i." So "60 characters" is an approximation, and it's usually a good one.
What happens when you go over: Google crops at the word boundary closest to the limit and adds "…" — which means you lose your brand name, your call to action, or whatever you put at the end. Which is also why brand name goes at the end.
On mobile, the limit is shorter. Closer to 78 characters of available space but with smaller text, so the rendered width is similar. In practice, if it fits cleanly at ~55–60 characters, it's fine everywhere.
What Google actually shows
Google doesn't always show your title verbatim. It rewrites titles too — not as aggressively as descriptions, but it happens. Common triggers:
- Title too long: It'll trim or rewrite to something shorter.
- Title too short or vague: Google may pull in the
<h1>or page heading instead. - Title stuffed with keywords: Google increasingly ignores or rewrites these.
- Title doesn't match the page: The strongest trigger. If your
<title>says "Best Pizza in Rome" and the page is clearly a listicle of pizza restaurants in Rome, Google will rewrite it to match what it thinks the page is actually about.
The safest approach is to write a title that honestly describes the page. Sounds obvious. You'd be surprised how often it doesn't happen.
Keyword placement: front-load it
The closer the target keyword is to the beginning of the title, the more weight it carries — both for ranking and for scan-ability. When someone's eyes sweep a list of search results, they read left to right and stop at the first thing that matches their intent.

Same page, same keyword. The second version is keyword-first, under 60 characters, and actually tells you what you're clicking on.
Brand at the end, always. Most people already know they're on your site by the time they're reading the title — but they don't know yet whether the page answers their question. Answer the question first.
Meta descriptions: not a ranking factor, but that's not the full story
Google has been clear for a while that meta descriptions don't directly influence rankings. What they do influence is click-through rate — the percentage of people who see your result and actually click it. And CTR is a signal Google pays attention to when evaluating whether a result is useful for a given query.
So: not a ranking factor itself, but it feeds one. Write it like it matters, because it does.
The length
The desktop limit is roughly 155–160 characters before Google truncates with an ellipsis. On mobile, it's shorter — closer to 120 characters in many cases, sometimes less. If you want a description that shows fully across devices, aim for 120–150 characters. You'll see "160 characters" cited constantly, but that's the desktop ceiling, not a guaranteed safe zone.
What truncation looks like in practice:
"Learn the exact character limits for title tags and meta descriptions, what Google truncates vs. rewrites, and how to write both so…"
The ellipsis is the punishment for going long. It makes the snippet feel cut off mid-thought, which doesn't exactly inspire confidence.
What Google shows vs. what Google rewrites
Google rewrites meta descriptions a lot. Studies have put the rewrite rate at over 60% across large samples — and while the exact figure varies depending on query type and site, the qualitative reality is consistent: Google pulls what it thinks is the most relevant excerpt from your page content for the specific query, and that may or may not be what you wrote.
That said, there's a range:
- For navigational queries (someone searching your brand name), Google usually shows your description verbatim.
- For informational queries, it's more likely to pull a snippet from the body of the page that directly answers the query.
- For transactional queries, it depends on whether your description front-loads the intent match.
The practical implication: your meta description is most likely to get shown when it matches the query intent better than any passage from your page content. So write it for the times it doesn't get rewritten, which means: lead with the thing the searcher wants to know, not a vague introduction to the page.
The "write for the rewrite" idea
Since Google will pull from your page content when it decides your description isn't a good match, the logical move is to make sure the best answer-forward sentences are in the page content, not just in the meta tag. Good copy on the page helps both ways: it gives Google something to pull when it rewrites, and it gives users something to read once they land.
This doesn't mean abandoning your meta description. It means your description and your content should be consistent — same intent, same specificity, same tone. If they're wildly different, that inconsistency is often why Google prefers to rewrite.
A do/don't table because sometimes that's just the right format
| Title tag | Meta description | |
|---|---|---|
| Do | Lead with the primary keyword | Lead with the user's intent or question |
| Do | Keep it under ~60 chars | Aim for 120–150 chars |
| Do | Put the brand at the end | Include a reason to click |
| Do | Match what's actually on the page | Be consistent with your page copy |
| Don't | Repeat the keyword three times | Copy-paste the first paragraph |
| Don't | Use the same title on multiple pages | Write one generic description for every page |
| Don't | Use all caps or excess punctuation!!! | Use vague phrases like "learn more" or "click here" |
| Don't | Let a CMS fill it in with "Home" or "Untitled" | Leave it blank and let Google guess |
That last "don't" in each column is where most of the real damage happens. A blank meta description gives Google full license to pull whatever it wants — which is sometimes a cookie consent popup, navigation text, or a footer link. Seen it happen.
And that second-to-last "don't" in the title column: duplicate title tags are one of the most common technical SEO problems on CMS-heavy sites, and one of the quietest. Two pages with the same title compete against each other in the index. Google has to pick one, often picks the wrong one, and you lose ranking potential on both.
Weak vs. strong — a real example
Let's make this concrete. Same page: a guide to meta description length.
Weak pair:

This article covers everything you need to know about meta descriptions, including how to write them and what length is best for SEO purposes in the current year.
Problems: title leads with brand (wrong priority), description is 168 characters (truncated), says nothing specific, reads like AI filler, has zero reason to click.
Strong pair:
- Title:
Meta Description Length: Limits & What Google Shows - Description:
Google rewrites descriptions more than half the time. Here's the character limit that actually matters, what triggers a rewrite, and how to write for the times it doesn't.
Title: 51 characters, keyword-first, specific promise. Description: 172 characters — slightly long, but the cut-off point falls after "rewrite," which still reads as a complete sentence. More importantly: it's interesting. It answers why you'd click.
The description in that "strong" example is on the long side and I know it. In practice I'd trim "and how to write for the times it doesn't" to get under 155, but the structure and intent are right.
The pixel-width thing, briefly
Because someone always asks: yes, you can use a title tag pixel-width calculator to check your exact title before publishing. Tools like serpsim.com or Portent's title tag tester render the title in the actual font Google uses (Arial, on desktop) and show you where the chop happens. Worth using for important pages. Not worth obsessing over for every post — the ~60 character heuristic is close enough for day-to-day work.
The more useful habit is reading your title out loud. If it sounds like a keyword list rather than a sentence, Google's rewriting it. If it's specific and honest about what the page contains, you're probably fine.
One last thing
These limits don't exist to make your life harder. They exist because search result UI has finite space and Google is trying to show something useful in that space. When your title gets truncated, it's not a punishment — it's a signal that you tried to fit too much into the slot.
Write one clear thing per title. One clear pitch per description. Keep both honest about what's on the page. That's what survives rewrites, truncations, and whatever Google's UI team decides to change next quarter.
