You rewrite a page's title and meta description on Monday. Your crawler picks up the change immediately. A week later, Google still shows the old text. Something must be broken.
Almost certainly not. Two separate things are happening, and they are easy to confuse. Google takes time to recrawl a page, and even once it has, it is under no obligation to use your description.
The distinction matters, because the two causes call for opposite responses. One needs patience. The other needs a rewrite, or an acceptance that the page will often be described in Google's words rather than yours.
What Google actually does with your meta description
The text under a result's title is a snippet, and the meta description is not its main source. The Google Search Central documentation on snippets is explicit: snippets are built primarily from page content, and Google uses the meta description tag only when it considers the tag a more accurate description of the page than the content itself.
Two further points from that documentation explain most confusing cases:
- The snippet is meant to surface the part of the page that best answers the query, so Google can show different snippets for one page depending on what was typed.
- There is no official length limit. The snippet is simply truncated in the results, usually to fit the screen width.
The same logic applies to titles: Google builds the title link from the title element, the H1 and the anchor text of inbound links, and can replace yours.
How often does Google rewrite descriptions?
Two studies published in 2020 remain the most cited work on the question. They do not measure quite the same thing, but they point the same way.
| Study | Sample | Main finding |
|---|---|---|
| Ahrefs (October 2020) | 20,000 keywords, first page of results | 62.78% of descriptions rewritten; 59.65% on generic and 65.62% on long-tail queries; 25.02% of top-ranking pages had no meta description |
| Portent (September 2020) | 30,000 keywords from the agency's own clients, desktop and mobile | 71% rewritten on mobile, 68% on desktop; the higher the keyword's search volume, the less often Google rewrote |
Sources: the Ahrefs study and the Portent study. Both date from 2020 and looked at English-language results, so treat the decimals with caution. The order of magnitude is what matters: in roughly two cases out of three, the text displayed was not the text someone had written. A replaced description is not an anomaly; it is the default.
Why your new description has not appeared yet
Three explanations cover almost every case, each with a different response.
1. Google has not recrawled the page
Your crawler reads the site live. Google shows what it recorded on its last visit. Between the two there can be a few hours for a busy page, or several weeks for a secondary page on a small site. Google's documentation on requesting a recrawl states that crawling can take from a few days to a few weeks, and that asking repeatedly for the same URL speeds nothing up. If pages routinely sit uncrawled for weeks, that is a separate problem: look at how your pages get indexed first.
2. Google has recrawled, but prefers an extract from the page
This is the most common situation once the delay has passed. Google's documentation lists descriptions it has no reason to use: keywords separated by commas, the same sentence repeated across every page, or text that does not summarise the page. Then there is the query itself. If someone searches a precise phrase that appears in your body copy but not in your description, Google shows the passage containing it.
3. A technical fault means Google never sees the right tag
Less frequent, but rule it out first. The causes I see most often on WordPress sites:
- two
meta descriptiontags in the source, one from the theme or an old plugin, the other from Yoast or Rank Math; - a page cache or CDN still serving the previous HTML;
- the description typed into the wrong field — the WordPress excerpt rather than the SEO plugin's;
- a tag injected by JavaScript after load, which Google may not treat like one present in the served HTML.
If the same page keeps reverting, or several pages share one description, the fault usually sits in the template or plugin configuration rather than the page — the kind of thing a technical audit catches.
A four-step diagnosis
Allow ten minutes, with a browser and access to the site's Search Console.
| Step | Tool | What you are checking |
|---|---|---|
| 1. The code actually served | Page source (Ctrl+U), in a private window | A single meta name="description" tag carrying the new text. If the old text is there, clear the site cache and the CDN. |
| 2. The version Google holds | Search Console, URL Inspection tool | The last crawl date and, via "View crawled page", the HTML Google recorded. If that date precedes your edit, the problem is a delay. |
| 3. Request a recrawl | Same tool, "Request indexing" | Google says indexing usually takes about a day, sometimes far longer, and a daily quota limits requests. |
| 4. The snippet per query | Google search on several queries: brand name, exact phrase, long question | If your description shows on some queries and not others, Google has registered the change and is adapting the snippet to the search. |
One practical note: the cache: operator and the "Cached" link, long used for this check, were retired by Google in 2024 (as reported by Search Engine Land). URL Inspection is now the only reliable way to see the version of a page Google holds.
Writing a description Google has a reason to keep
You cannot force your text to appear. No tag and no structured data imposes it: the nosnippet and max-snippet directives in the robots meta tag documentation restrict or suppress a snippet, never dictate its contents. What you can do is raise the odds that Google judges your description more useful than its own extract. Its recommendations come down to four points, which practice tends to confirm.
- One description per page. Google names duplicated text explicitly as a case where the tag is ignored. On a small site, write them by hand. On a catalogue, generate them from fields specific to each item — reference, brand, price, availability.
- A faithful summary, not a sales line. Google cites author, date, price and manufacturer as the kind of detail that belongs there. Unverifiable claims and strings of emoji do not make a description more acceptable, and cost credibility with the reader.
- Consistency with the opening of the page. When the description restates, in other words, what the first paragraph says, Google has less reason to look elsewhere. If a quick read cannot confirm your description, rewrite it.
- The essentials in the first few words. With no official limit, display is still truncated: the 2020 Portent study observed roughly 150 to 160 characters on desktop and around 120 on mobile, fewer when a date preceded the snippet. Put the decisive information at the front and treat the tail as optional.
Then measure the right thing: not whether your text is displayed, but whether the page is clicked. The Performance report in Search Console gives impressions and click-through rate per page and per query. Compare the weeks either side of a rewrite, remembering that ranking movements and seasonality sit in the same numbers.
What this looks like in practice
In most cases that reach me, the source check confirms the new description is live and unique, and URL Inspection shows a crawl date earlier than the edit. Google has not been back. A recrawl request and some patience settle it.
What usually goes unsaid is the rest. Even once recrawled, the description shows on some queries only, typically those about the company name or the page's central subject. On more specific searches, Google keeps drawing from the body copy. That is not a failure; it is how snippets work.
So treat the description and the opening paragraphs of each important page as one job. Between them they supply almost everything a searcher reads before clicking. For a broader review, it pays to scope the audit around the pages that actually earn impressions, rather than rewriting every description on the site.
Common questions
How long does it take for Google to show a new meta description?
Google displays the text it recorded during its last crawl. Its documentation states that crawling can take from a few days to a few weeks, and that an indexing request through Search Console is usually processed in about a day, sometimes far longer. The delay depends mainly on how often Google visits your site.
Why does Google rewrite my meta description when there is nothing wrong with it?
Google builds the snippet from page content first, and uses the meta description only when it judges the tag more accurate. It also adapts the snippet to each query: a search for a phrase absent from your description pulls the passage containing it. The 2020 Ahrefs and Portent studies both found the description replaced in roughly two cases out of three.
Can you force Google to use the meta description?
No. No tag and no structured data dictates the contents of a snippet; the nosnippet and max-snippet directives only suppress or shorten it. All you can do is make the description more useful than what Google would extract itself: unique, faithful to the page, and consistent with its first paragraph.
How long should a meta description be?
Google sets no limit, and the snippet is truncated according to screen width. The 2020 Portent study observed roughly 150 to 160 characters on desktop and around 120 on mobile, fewer when a date preceded the text. Put the essential information first and accept that the end may never be seen.
How can I see the version of my page that Google holds?
Use the URL Inspection tool in Google Search Console: it gives the last crawl date and lets you view the HTML Google recorded. The cache: operator and the "Cached" link were retired by Google in 2024 and no longer work.
Does a missing meta description hurt rankings?
No. It is not a ranking factor, and the 2020 Ahrefs study found about a quarter of top-ranking pages had none. Google generates a snippet from the content instead. A good description is still worth writing: it gives you partial control over what searchers read, and over the page's click-through rate.
