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: Webpage Titles.
- The title must be unique in your website.
- The name of the webpage should the same as the title but the words separated by '-' or '_', such as my webpage name: google:webpage-titles.
- These words should be also used through out the webpage.
- 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 webpage title.
