HTML tags, such as
<TITLE>, <H1>, and <H2> are also searched by Google’s Web crawler for keywords.
The link text
The URL, or link text, has always been important in determining a page’s relevance. When the URL of a
Web page contains the keyword it will be considered much more relevant by Google than a page that may
contain the keywords within the text but not within the link text. For example, when you search for the
word house using Google, the first five results have the word house in their URLs as shown in Figure 1.2.
FIGURE 1.2
When search terms appear in the URL, they are considered more relevant.
The Web browser shown in Figure 1.2 displays the Google Toolbar. See Chapter 31 to learn
more about downloading and installing the Google Toolbar. Another factor Google takes into
account when considering page relevancy is the frequency with which the keyword appears on the Web
page. The more times the word you are searching for appears within the Web page the higher the relevancy
of that page.
PageRank
PageRank was created at Stanford University in 1985 as part of a research project studying a new kind of
search engine. The project was developed by Larry Page and Sergey Brin. They created a functional search
prototype that they called Google. Shortly after creating the PageRank technology Larry and Sergey founded
Google, Inc., making use of the PageRank technology as a key element in its new Web search software.
