Finding useful and informative content on the World Wide
Web is something that many of us take for granted. There are near about
150,000,000 active Web sites on the Internet today, according to the Internet
research firm Netcraft. The task of filtering through all those sites to find
helpful information is enormous. That's why search engines use complex
algorithms, mathematical instructions that tell computers how to complete
assigned tasks to it.
algorithm does the work for you by searching out Web pages that contains the
keywords you used to search, then assigning a rank to each page based on several
factors and techniques, including how many times the keywords appear on the
page. Higher ranked pages appear first up in Google's search engine results page (SERP), which means that the best links
relating to your search query are theoretically the first ones Google lists.
For Web page administrators, being listed prominently on
Google can result in a big boost in site traffic and visibility. In 2007,
Google declared Microsoft as the most visited site on the Web [source: The San
Francisco Chronicle]. With that much traffic, getting a good spot on a Google
SERP could mean a huge boost in the number of site visitors to your website.
Google's keyword search function is almost similar to
other search engines functionality. Automated programs which are called spiders
or crawlers travel through the Web, moving from link to link and building up an
index page that includes certain keywords matching with the search keywords.
Google references this index when a user enters a search query. The search
engine lists the pages that contain the same keywords that were in the user's
search terms. Google's spiders may also have some more advanced functions, such
as being able to determine the difference between Web pages with actual content
and redirect sites pages that exist only to redirect traffic to a different Web
Keyword placement plays a crucial part in how Google
finds and indexes sites. Google looks for keywords throughout each Web page,
but some sections are more important than others. Including the keyword in the
Web page's title is a good idea, for example. Google also searches for keywords
in headings, title of the page and name of the file. Headings come in a range
of sizes, and keywords in larger headings are more valuable than if they are in
smaller headings. Keyword dispersal is also important. Webmasters should avoid
overusing of keywords on a page, but many people recommend using them regularly
throughout a page as Google disregards it.
