Meta Titles and Descriptions: Write Them for Clicks

Your title tag is a strong suggestion and your meta description is a weaker one — Google generates both from the page when it judges its own version better, and it publishes no character limit for either.

That is not a reason to stop writing them. It is a reason to write them for a different purpose than most guidance assumes: the title exists to describe the page unambiguously enough that Google keeps it, and the description exists to earn a click if Google uses it.

What Google actually says

Two pieces of documentation settle most of the arguments here.

On titles: the title link is "truncated in Google Search results as needed, typically to fit the device width." No character count is given. Google generates the title link from your <title> element, the main visual title, headings, og:title, prominent styled text, anchor text on the page, and text in links from other sites.

On descriptions: "Google primarily uses the content on the page to automatically determine the appropriate snippet. We may also use descriptive information in the meta description element when it describes the page better than other parts of the content." Again, no length limit — the snippet is "truncated in Google Search results as needed, typically to fit the device width."

Two conclusions follow. The 60-character and 155-character conventions are proxies for what fits on a phone, not rules. And your description is a candidate, not a specification.

Writing a title that survives

The goal is a title Google keeps, and Google rewrites when a title is incomplete, inaccurate, duplicate boilerplate, or when the page's main heading is unclear.

Five things that make a title survive:

• Specific to this page. "Email Deliverability Guide" describes forty thousand pages. "Why Authenticated Emails Still Land in Spam" describes one.
• Matching the visible H1. When the <title> and the on-page title disagree, Google chooses — sometimes yours, sometimes the H1, sometimes something else entirely.
• Front-loaded. The distinguishing words first, because truncation removes the end.
• Not boilerplate. A repeated template across hundreds of pages is the most common rewrite trigger there is.
• Brand at the end, or absent. On a site nobody is searching for by name, a brand suffix spends characters that could be describing the page. On a known brand it earns its place.

The pattern that works

Primary description of the page — the distinguishing detail.

• Email Bounce Rate: What's Normal and How to Fix It
• robots.txt Mistakes That De-Index Whole Sites

Both are specific, front-loaded, and would be difficult for Google to improve on — which is the actual test.

What gets rewritten

• "Home | Company" or "Blog | Company" — no information at all
• The same template on every page — boilerplate, named explicitly in Google's documentation
• Keyword stacking — "Email Marketing, Email Deliverability, Email Software | Company"
• A title that promises something the page does not deliver — inaccuracy, and the one with consequences beyond the rewrite

Writing a description that earns the click

Assume Google might not use it. Write it anyway, because when it is used it is the only sales copy you get.

What makes a description work:

• It continues the title rather than repeating it. The title states what the page is; the description says what the reader will get.
• It names something specific. A number, a method, a named thing. "Learn everything about email deliverability" says nothing; "the five causes, in the order that finds the problem fastest" says what is inside.
• It matches the page. Google's own guidance is that the description should accurately describe the specific page — and a description promising more than the page delivers produces a click and a bounce, which helps nobody.
• It is unique. Duplicate descriptions across pages are one of the clearest signals to generate a snippet instead.

What does not work: keyword strings, which Google's documentation names directly; calls to action in the description, which waste the space the reader is using to decide; and writing to a character count rather than to a complete thought.

When Google replaces yours

It is not a penalty and there is nothing to appeal.

Descriptions get replaced constantly, and often for a sensible reason: someone searched for a specific phrase, and Google found a passage on your page that answers it more directly than your general description. That is the system working. A page can legitimately show a different snippet for every query it ranks for.

Titles are different. A rewritten title usually means Google found your title unhelpful, and that is worth investigating. Check whether it is boilerplate, whether it matches the H1, and whether it actually describes the page.

What to do about it:

Situation	Response
Description replaced, snippet is good	Nothing. Google found a better passage for that query
Description replaced, snippet is poor	The page probably lacks a clear passage answering that query. Add one
Title replaced with something better	Take the hint — Google's version describes the page more accurately
Title replaced with something worse	Check for boilerplate, competing headings, and title/H1 mismatch

How to find the ones worth rewriting

Not all of them. The pages worth working on are the ones already ranking and failing to convert impressions into clicks.

In Search Console, Performance, Pages:

1. Sort by impressions, not clicks
2. Look at pages with high impressions and a low click rate
3. Those pages are visible and not being chosen — which is exactly what a title and description fix addresses

Ignore pages with low impressions. They are not being seen, which is a relevance or authority problem, and no title rewrite will change it. The diagnostic is in on-page SEO.

Measure honestly. Click-through rate varies enormously by position, query type and whether an AI Overview sits above the results. Compare a page against its own previous performance rather than against a published benchmark.

Frequently asked questions

How long should a meta title be?
Google publishes no limit. Its documentation says title links are truncated as needed, typically to fit the device width. The 60-character convention is a reasonable proxy for what fits on mobile, so front-load the distinguishing words and check how it renders rather than counting characters.

How long should a meta description be?
Google states there is no limit and that the snippet is truncated to fit the device width. Around 150 characters is a workable proxy. Completeness matters more than the count, because a description cut mid-sentence reads worse than a shorter finished one.

Why is Google not using my meta description?
Because it found a passage on the page that better answers the specific query. Google says it uses the meta description when it describes the page better than other parts of the content, so replacement is usually the system working rather than a fault. A poor replacement suggests the page lacks a clear passage on that query.

Why did Google rewrite my title tag?
Most often because it is duplicate boilerplate repeated across pages, is unclear or inaccurate, or conflicts with the page's main heading. Google builds the title link from seven sources including your title element, the visible H1, headings and even anchor text from other sites.

Do meta descriptions affect rankings?
No. They affect click-through rate when Google uses them. Writing one is a conversion investment rather than a ranking one, which is also why obsessing over keywords in it is wasted effort.

Should I include my brand name in the title?
At the end, if at all. On a site people search for by name it earns its place. On one they do not, a brand suffix spends characters that could describe the page — and Google may remove it anyway.

Should every page have a unique description?
Yes, where you write them at all. Duplicate descriptions across pages are among the clearest reasons for Google to generate its own snippet instead, and they tell a reader nothing about which result to choose.

How do I find which pages need better titles?
Sort Search Console's Pages report by impressions and look for high impressions with a low click rate. Those pages already rank and are not being chosen, which is exactly the problem a title and description rewrite solves. Low-impression pages need something else entirely.

What to do next

Open Search Console, Performance, Pages, sorted by impressions. Find the pages being seen a lot and clicked rarely. That list — usually shorter than people expect — is your entire rewrite queue.

Then check the top three against their <title> and their H1. If those two disagree, you have already found why Google is choosing for you.
