Important Search Engines

Search Engine Breakdown
***********************
Ever notice that performing the same search on the major engines gives you different results? Yes, some of it is because of the algorithms and how the engines use different factors in their rankings, but pay attention to the results and a pattern has emerged.

For the sake of being fair, Ask has been included since they do serve up results in a slightly different manner. So here's how the engines shake out:


Google:

Information Engine
Loves Wikipedia and the results show it
Relies heavily on trust factors (see Google Trustrank)


Yahoo:

Social Engine
Many results have ebay listings (a Yahoo partner), del.icio.us (Owned by Yahoo) and Flickr results (Owned by Yahoo)
Tries to incorporate Yahoo Answers into many results


MSN:

Product Engine
Almost always has results for product based searches not found in the other engines
Starting to use more Wikipedia results as their algorithm matures


Ask:

Clustering Engine
Their results try to give you all the surrounding information around your search term
Trying to get into the mindshare of America

So, as you can see, each engine does provide a different slice of information depending on your search need. Keep this in mind when you are not only looking for something, but when selecting the keyphrase you want to be ranked for.

-To your online success!

WHAT IS SEO?

SEO - An Explanation of Search Engine Optimisation
Search Engine Optimisation (SEO) or Search Engine Optimization as the Americans call it, is the practice of modifying a website so that it is considered to be Search Engine Friendly. If a website can be properly read by the search engine spiders, there is an increased probability of achieving desirable results in the Search Engine Result Pages (SERPs).

The primary task for a Search Engine Optimisation company is to understand what the search engines are looking for and which techniques they give greater credibility to. This is the Holy Grail of search engine optimisation and even though some companies employ "Black Hat" techniques to deceive each search engine, natural and ethical Internet marketing techniques that are approved in the Search Engine Optimisation industry prevail for search engine listing longevity.

SEO ROBOTICS

A web page creator can specify which page should be indexed and which page should not be indexed by search engines by placing Robots META tag in the HTML section

Here are some Robots tags that are common

< content="NOINDEX" name="ROBOTS">- Ignore content and follow links
< content="NOFOLLOW, INDEX " name="ROBOTS">- Include content and do not follow links
< content="NOINDEX,NOFOLLOW" name="ROBOTS">- Ignore content and do not follow links
< content="INDEX,FOLLOW" name="ROBOTS">- Include content and follow links
< content="NOARCHIVE" name="ROBOTS">- Cache link should not show Search results pages
< content="NOODP" name="ROBOTS">- The Open Directory Project (ODP) title and description for the page should not be displayed in Search results
< content="NOYDIR" name="ROBOTS">- The Yahoo Directory title and description for the page should not be displayed in Search results
< content="NOSNIPPET" name="ROBOTS">- Titles are only displayed in Search results page and not description or text context for this page

In addition to manage folder level user agent control robots.txt file can be used. This file can be placed in root of each server and the format is plain text not HTML

Through this file website owner or webmaster can allow access to web page content and disallow access to admin, cgi and any secured files that you don’t want search engines to index

A typical robots.txt file will look like

User-agent: *
Allow: /
Disallow: /admin*
Allow: *content*
Disallow: /test/
Disallow: /paypal/
Disallow: /credit/
Disallow: /cgi/

Explains, all robots can crawl except the admin files, and crawl files named content folder, and should not crawl test, paypal, credit and cgi folder.
