Search Engine Algorithm - the formula behind better web prominence

One thing that a web promotions specialist should know at the snap of the hand is the functioning of Search Engines. A better understanding of the search algorithm can only help a web promotion specialist in cashing on the booming Search promotion and marketing domain; and deliver a suitable and affordable web promotion solution to the clients. And when it comes to knowing the basis of a search engine functioning, the long lived dream remains to fathom the 'algorithm' - the formula of the entirety.


But mastering 'algorithm' is never going to be an easy task - especially going by the fact that the same construes the reason of the whole competition in the SEO domain.



Here's a little information that we've tried to put together to help a web site promotion firm like yours to brush up on a few basic concepts:




Algorithm in general can be described as a sequence of instructions used for data processing and calculation.

Search algorithm is defined as an algorithm which accepts a problem as an input and returns a solution to the problem after a thorough evaluation of the various possible solutions.


In general, information retrieval systems or search engines match queries against a set of indexes and displays relevant results. To be more specific, a typical search engine has four essential modules:


1.A document processor module

2.A query processor module.

3.A search and matching function.

4.A ranking system.


A Document processor collects, prepares, processes and inputs the pages/sites in the form of an index called an inverted file.
A query processor divides every query into cognizable segments for the search engine to match against the 'index'.
Next, we have a 'search and matching' function, which actually searches through the umpteen indexes and matches them to the query requirements. The matched results are displayed for the user!
On what basis is the order of the results displayed decided? This is where the 'ranking system' or say algorithm pitches in.


Every search engine has an algorithm, on the basis of which the results are evaluated and displayed to the user. For example, Google follows the indigenous Page rank algorithm. These algorithms form the basis of the evaluation of a website and take into consideration various aspects like:



Frequency of keywords.
Placement of keywords.
Back-links to the website and so on.


A web promotions specialist, being the reason behind a website's search engine adequacy, should be more in line with the evaluation criterion and overall algorithms of the search engines.
