Google: Webpage Titles
Titles for pages on your site should accurately describe the focus of that particular page and also might include your site or business name.
— Google: Search Engine Optimization Guide
The titles are in the markup: <title> … </title>
- The title must be readable, such as my title for this page: Google: Web page Titles.
- The title must be unique in your website.
- The name of the web page should the same as the title but the words separated by '-' or '_', such as my web page name: *google:web page-titles*.
- These words should be also used through out the web page.
- The titles must be short and informative. If the title is too long, Google will truncate the title and will show only the beginning of your title.
- Avoid stuffing keywords in the web page title.
