The Generic Search Engine Algorithm
by: Stephen C. Parker, April 2004
My goal in this article is to explain the components of a generic search
engine algorithm. Each search engine calculates and weights these
components differently, but all use them in their final page rank
calculations. The reader must remember that a highly optimized site
that uses these search engine optimization techniques to gain a higher page
rank on the search engines, does not equal a complete marketing plan.
High Search Engine rank is one goal in a well balanced Internet Marketing
plan.
Key Components of a Generic Search Engine Algorithm
-
Keywords / Search Terms
-
URL / Domain Name
-
File Names / Directory Structure
-
Page Title (header)
-
Header Tags / Bold Text
-
Meta Tags
-
Alt Tags
-
HREF Tags / Links
-
Body Text / Copywriting
-
Link Popularity / Page Rank
- Keywords / Search Terms
-
As you might guess, this is the most important component of
the search engine algorithm. What will potential customers / visitors type
into the search engine to find your web site? If you get this wrong,
perfecting all other components is a useless task.
-
- URL / Domain Name
-
Many already have their domain name / URL and its the
company name or a derivation of it. That's a pretty good choice if your
company is a recognized brand, but you may also want to consider a domain
name with your top keyword in it. For example, consider "diamonds" as
your top keyword and your company distributes diamonds, a good URL might be
diamonds.com or diamondtrader.com. Search Engines love keywords in the
URL, this will give you a significant page rank boost.
-
- File Names and Directory Structure
-
Like the URL, one should include keywords in their file
names and directory names. Why use first_page.htm, when one can use
diamond_cuts.htm. Search Engines give a fair amount of weight to this
strategy. One should also try to keep the file structure flat vs. many
folders. If you are using a database, make sure the file names are not
over 75 characters and do not include spider killers such as "?."
-
- Page Title
-
This is not the first line of your web site, but the Title
tag in the header area of your html code. This text is displayed in
the upper left of the browser window when the page is visited. The
Page Title is very important to search engines, especially Google.
Each page should have a single keyword phrase that is used in the Page
Title. Do not use more than 50 letters in the page title.
-
- Meta Tags - Keywords and Description
-
Meta Tags have fallen on hard times recently, especially
keyword meta tags. Currently, Google is not giving weight to them but
the new Yahoo Search is looking at them closely. I like to choose two
to three keyword phrases per page and stuff these in the keyword meta tag.
Make sure you use these terms throughout the page body text. The Meta
Tag description is widely used. Google uses this in their search
results to help describe your site. I like to reuse the Page Title
keyword phrase as the first phrase in the Meta Tag Description and repeat it
twice to make some type of coherent sentence. One should not worry
about using their company name in these areas unless your name is a top
brand. Most people will click on a top search result and your web site
will display your name.
-
- H1 Tags / Bold Text
-
Like Meta Keywords H1 Tags and Bold Text has fallen out of
favor. Do not overuse these attributes. Use them as needed in
design but not part of your optimization strategy. I would not repeat
and H1 tag more than twice on the page.
-
-
- Alt Tags
-
Image Alt Tags are a good area to stuff a few keywords.
- HREF Tags URL
-
Search Engines like keyword related links on a web site.
A good way to do this is to use the <a href="page" title= "sub keyword">main
keyword</a> syntax.
-
- Body Text / Copywriting
-
Many people stuff keywords into their meta tags and run.
Well, this strategy does not work. An optimized web site uses the main
keyword throughout the page to increase keyword density for the page.
One should keep the keyword density lower than 10% for the page. Many
people need to rewrite their copy to include their top keywords.
-
- Link Popularity
-
Does Link Popularity really work? According to Google
it has an effect. Google gives weight to your site if other sites
related to your site link to your web site. Google calls their
calculation of Link Popularity as "Page Rank." I really do not know
how weighted this component is for optimization, but I do know that links to
your site is good advertising, so one should pursue links vigorously.
This was a brief summary of the main components of generic search
engine algorithm. There's a ton more to learn but this should
jump start your learning curve.
