What is a title tag, and how does Google use it?
What a title tag is, how Google turns it into a title link, and how to write one
A title tag is the <title> element in a page's HTML, and Google uses it as one of several sources when it writes the title link, the clickable title of a search result. Google sets the title link automatically, so the title tag states your preference and doesn't promise the result. Following Google's best practices, such as giving every page a descriptive, concise, distinct title, is how you indicate your preference.
Title tag and title link
The title tag is the <title> element you write in the page's HTML. The title link is what Google shows as the clickable title of a search result. They're often the same text, but not always, because Google builds the title link automatically from several sources, and the <title> element is the one you control most directly.
Google calls the title link critical to giving users a quick sense of what a result is about, and says it's often the main thing people use to decide which result to click.
Writing a good one
Give every page a title in the <title> element, and make it descriptive and concise.
Avoid vague labels like 'Home' or 'Profile', and avoid long, wordy text. There's no length limit on the element itself, but Google truncates the title link as needed, typically to fit the width of the device. Use a few descriptive terms, not the same words repeated.
Google says keyword stuffing can make results look spammy to Google and to users.
Distinct titles and branding
Each page needs its own title that describes its own content. Titling every page on a commerce site 'Cheap products for sale' makes the pages impossible to tell apart. Long boilerplate titles that change by only one detail are also poor, and Google suggests generating the title from what the page actually contains.
The home page title is a reasonable place for a longer description of the site. On other pages, Google suggests just the site name at the start or end, set off with a hyphen, colon, or pipe.
Other signals Google reads
Because Google also looks at the main visual title and headings, it helps to make the main title clearly the most prominent text on the page, for example in the first visible <h1> and in a larger font. Several headings with the same visual weight can make it unclear which one is the title.
Blocking a page in robots.txt doesn't always keep it out of the index. If Google indexes a page it can't read, it may build the title link from off-page content such as anchor text from other sites.
To keep a URL out of the index, use the noindex rule.

Questions
How long should a title tag be?
Google sets no limit on the length of the <title> element, but it truncates the title link in search results as needed, typically to fit the device width. Google's advice is to keep titles descriptive and concise and to avoid long, verbose text.
Why does Google show a different title than my title tag?
Google determines title links automatically from several sources, including the <title> element, the main visual title, headings, and other prominent text. Your title tag indicates a preference, and Google may draw on those other sources.
Should I put my brand name in every title tag?
Google suggests keeping branding short. Put just the site name at the beginning or end of each title, separated by a hyphen, colon, or pipe. A longer description of the site fits on the home page title.
