What’s the most important thing on a webpage for search engines like Google, Bing, and Yahoo?
The most important element of a given webpage on a website is the title tag. The title tag is at the most general level, the title of the webpage. Search engines like Google place a high value on the title tag because it is hard to abuse or spam because of the limited real estate.
Search engines will only recognize a limited number of characters in a title tag. For example, Google will only read the first 60-70 characters of a title tag, including spaces. Because of this a website owner cannot stuff the title tag with a bunch of keywords, instead they must be very selective in their choices. In other words the title tag summarizes the focus of the page in 70 characters or less.
