Search EnginesThose of us who work in
IT industry know that
key to success is knowledge. Knowledge of your chosen market, of your competitors, new software, new hardware and a million other things that you need to know.
Granted, it’s not an easy task. It often takes dedicated ‘geeks’ continually surfing
Net for
necessary information day in, day out, to filter through
masses of information overload that is commonplace on
Net today. But there are certain ‘methods’ that might make it a bit easier and more efficient.
Most users of
Internet are familiar with ‘Search Engines’ but few understand how they actually work and although it isn’t necessary to understand
actual algorithms used for individual engines it’s important to have an idea of
type and quality of
results that get shown.
The main types of engines are
generic search engines such as Google and All The Web, next are
Directories such as Yahoo and finally there are
Meta Search engines such as IXQuick and Metor. Although there are others such as PPC’s and Mete-meta search engines (All in one) I won’t list them all as it may confuse
issue.
These engines provide results in different ways and, if you can understand them, will enable you to find more information on any particular topic than would normally be available to you if you were to use only one or two engines.
Firstly,
generic search engines use an automated searching program (spider) to try and locate any site that matches
query that you entered into its search box. It then lists them according to its own idea of what it believes is
most relevant to you. The directories, however, have humans to sort out different sites into different sections and hopefully weed out sites that would not be appropriate to your request. These are a bit more limiting but often give quality information. Lastly we have
Meta search engines, these utilise
services of a multitude of different search engines to search simultaneously for sites that match your query. Again, they then sort out
sites according to what they believe might be
most relevant to you. The biggest use of these is to find leads for a subject you are not familiar with.
Ok, that’s
basics sorted out.
