Shown above the title on mobile, beside your favicon.
The Mobile SERP Preview draws your listing at three real phone widths, with the favicon and site name row above the title and the wrapping a mobile result actually uses. Mobile is where most searches happen and the layout differs from desktop in ways that change what you should write — including allowing more text, not less.
Type a title, URL and description and the tool draws the mobile result at real device widths — a small phone, a standard phone and a large one — because a snippet that fits on one can be cut on another. The favicon and site name row is drawn too.
Mobile is where most searches happen and it is the layout people check last. It differs from desktop in ways that change what you should write: the site name and favicon sit above the title rather than beside it, titles wrap onto two lines instead of being cut on one, and the description gets three lines rather than two. That means a mobile listing can actually carry more text than a desktop one — the opposite of what most people assume — while the narrow column makes long words and unbroken URLs far more disruptive.
A snippet that fits on a large phone can still be cut on a small one, so all three are drawn.
Favicon and site name sit above the title on mobile, and the preview includes them.
Mobile titles wrap to a second line, so where the break falls matters more than the total length.
Mobile gives descriptions more room than desktop, which is the opposite of what most people assume.
The preview is drawn from what you type, so unpublished pages preview fine.
Title, URL and meta description, exactly as they will be on the page.
Small, standard and large phone widths are drawn together, since they truncate differently.
Mobile titles wrap to two lines rather than being cut, so the break point matters more than the length.
Front-load the words that matter and the third line becomes the part you can afford to lose.
No, and this surprises people. A mobile title wraps onto two lines where a desktop title is cut on one, so mobile can display more characters. What mobile does punish is a long unbroken word or URL, because the column is narrow.
Google moved to a site name and favicon row above the title on mobile in 2022, and later brought it to desktop. It is drawn from your site name markup and your favicon, so both are worth setting properly.
You cannot — there is one title tag and Google decides how to render it. What you can do is write one that works on both, which in practice means front-loading and keeping it under the desktop limit, since that is the tighter of the two.
No. Everything is drawn from the text you type, in your browser. Nothing is requested and nothing is uploaded.
