Search Engine 101

Search Engine 101
When promoting your web site or online business most
webmasters are looking for more targeted visitors. Search
engine optimization otherwise known as SEO can help you
accomplish that goal. Sometimes small changes in SEO can
bring your website a tremendous amount of traffic by
bringing your website closer to the top of search engine
results.

A search engine searches the web for information on
relevant topics found on web sites. Internet searches are
performed using keywords. The search engines keep an index
of keywords and where they found them. For instance, if
you search for the keyword vitamin, the search engine will
return a list of sites that contain the word vitamin. The
search engines sort through infinite amounts of data to
help searchers find exactly what they're looking for.

In order for a search engine to be able to provide relevant
results it has to find the information for itself. This is
done using what are called web robots or spiders. These
spiders constantly "crawl" the Internet looking for new
content. Once they find this information it is organized
and indexed into a list. In looking for new information
the web spiders generally begin on popular sites. From
there they spread out following every link on the website.
They index the words on the web sites and in the links
keeping track of where they were found.

At optimal levels the spiders are very fast covering about
100 pages per second. The spiders review web pages behind
the scenes from left to right top to bottom just like we
do. The keyword closest to the top is given more
relevance. As are keywords in bold, title text,
underlined, italicized or highlighted in some way.

In addition to the text you see the spiders also read the
meta tags on the site. Meta tags allow the webmaster to
select key words and ideas to help index the site.

Once the information is found and indexed it is organized
to be used by searchers. The index includes the key word
or key word phrase, The URL, and how many times the keyword
appeared on the page. The job of the search engine is to
return the most relevant results for your search, so key
words are weighted based on the density of the keyword on
the site.

The exact methodology used by the search engines is a
highly guarded secret. It is important to understand some
of the basics of how the search engines work in order to
optimize your page for the search engines.

If you want to maximize the traffic you receive from search
engines it is important to practice good SEO. There's a
tremendous amount of information available on the Internet
including articles, eBooks and even free courses teaching
SEO techniques.
