Search Engine Optimization
Search engines have quite a job trying to index the 500 billion
plus web pages on the WWW - a near impossible task. But the real
challenge comes when they attempt to evaluate the data and present
the most relevant pages in order of importance, (usually in very
long lists of matching results) for given keyword searches.
Search engines use complex and proprietary algorithms (or rules)
to sort this data, with varying degrees of success. They go to great
lengths to try and deliver the most relevant pages first, so although
a search may turn up hundreds of thousands of matches, the first
page or so of results should satisfy a searcher's needs.
Clearly, if we knew the rules, we might be able to apply these to
our web pages so that they score higher in the search engine ranking
schemes. This is the principle of search engine optimisation or
positioning. If only it were that easy!
Unfortunately there is a battle, which will probably never cease,
between the forces of the Spider (Search Engines) and the forces
of Commerce (web site owners). Search engines have strong competitive
pressure to deliver the most relevant results first. Web site owners
are equally pushed to manipulate their sites to get higher rankings.
The rules therefore keep changing; they are not published; and they
are generally only determined by inference from watching rankings
rise and fall - and through industry gossip. An excellent information
source on this subject is the Search Engine Watch site - see the
Links page.
Optimisation of a site to get the best ranking with search engines
has become increasingly competitive. Very aggressive techniques
may be penalised by the engines and result in extreme prejudice
though - so be very carreful!. Some of the bona fide methods for
optimisation are described on the search
engine tips page.
Whatever happens though, don't spam the engines - it is counterproductive,
unprofessional, and can result in banishment from search engine
lists altogether.
