The mobile version has a different title or description
In the reportPages serve a different title or meta description to the smartphone crawler
mobile_title_meta_mismatch · Review item
This appears when the title, or the meta description, that phones receive differs from the desktop one. Google builds its view of the page from the mobile version, so the desktop title may not be what it uses. Serve the same title and description to every device.
Severity: Medium. Review it in your next round of site changes; the difference can change how the page is presented in results.
Why it matters
Google indexes and ranks the mobile version of a page, and asks that the title element and the meta description be equivalent across the mobile and desktop versions.
What to do
- Look at the finding: it shows each response's title and description with spacing normalised, up to the first 128 characters of each, and marks any that were shortened.
- Find where the mobile template sets a different title or description, often a shorter default, and make it output the same values.
- Check again with this one address once the change is live.
When to leave it as it is: if the two versions say the same thing in slightly different words, Google's guidance asks only for equivalent values; the check compares the exact text, including letter case.
What we read
We take up to the first 20 crawled pages that answered 200 with complete HTML at your site's exact address, and request each one six more times: twice as desktop Chrome, twice as Googlebot Smartphone and twice as Chrome on an Android phone, each agent's repeat at least five seconds after its first request, and all six within three minutes. We compare the HTML as served, without running JavaScript. A page is not compared when robots.txt blocks any of these requests, any answer is not 200 HTML or shows a bot-challenge page, or a redirect leaves the page's scheme, host or port, for example to an m. site.
We read the first <title> and the first <meta name="description">, ignoring spacing but not letter case; a missing element counts as empty. A page is reported when the desktop title differs from both phone titles, or the desktop description differs from both phone descriptions. Each version must return the same title and description on its two requests, or the page is not judged.
Example & evidence
Illustrative example — one page's head on desktop and on phones, not a live audit.
Address: https://bakery.example/cakes/wedding-cakes. Desktop Chrome gets:
<title>Wedding cakes made to order | Example Bakery</title>Googlebot Smartphone and Android Chrome both get:
<title>Example Bakery</title>The desktop title differs from both phone titles, so the page is reported, even though the descriptions match.
A possible correction: let the mobile template print <title>Wedding cakes made to order | Example Bakery</title>. A version in different letter case would still be reported.
Confirm & check again
Check for yourself: view the page source as a phone, for example with your browser's device mode, and compare its <title> and description with the desktop source.
Check again: Full audit — re-read this address with a fresh set of six requests under the same conditions. The finding closes when the comparison comes out clear. It cannot conclude when any request is blocked, fails or shows a challenge, when a title changes between two identical requests, or when a response's first 64 KB is not plain UTF-8 text; a new full audit closes it when a fresh comparison of the page, again among the 20, comes out clear, or the address now answers directly with 200 and a file that is not HTML, or starts with a permanent redirect within your site; the second way needs no new comparison of this page. Both need the check to give a usable result in that audit and complete evidence for the old finding, and a finding reported again stays open.
Limits & sources
The check compares exact text, so equivalent wording in another form is still reported, and it does not say which version is better. Titles set by scripts are not seen, it is not confirmed by rendering, and a difference shown only to Googlebot, not to the Android browser, is not reported.
Confidence: Medium because the served values are compared, not the title link or snippet Google finally shows.
