All involved with SEO should always be aware of the behaviour
of Internet users, for both the SEO and Usability for the way people
behave is the main reading of facts to do, and understand their own
search engines.
Whenever there is the result of a study of market share, it is thought
that only in company grew, which went into recess and trends for these
companies. But in the end, the fluctuation of performance of companies
reflects the actual behaviour of people, especially among the search
engines.
Recently, compete.com released the results of the market share of
search engines for the month of February, and besides the data itself,
it is important to relate the result with the general behaviour of
people.

Transforming information in these percentages, the overall result is
that Google has increased by 2.2% in its share of the search market,
reaching 72.4% of market dominance. Yahoo! and MSN / Live both reported
declines: the MSN / Live, less significant, leaves Microsoft with a
mark of 6.3% of the search, and Yahoo! still holds 17.8% after falling
1.5% compared to January.
In evaluating the second block of data ( "Query Volume" - Volume Query)
is clearly the power of Google. All search engines with a drop in
search volume, but even so, Google managed to increase its share of the
market share of searches.
And What is your favorite search engine?
The result of that market share also shows is that Google is by far the
favorite search engine of Internet users, which explains why so much
talk about optimizing for Google (Google SEO), and not so much for
Yahoo ! or MSN / Live, which are nonetheless important because,
together, the tools represent 24.1% of the search.
Still, the growth of Google in that slice of the market indicates the
trend of people's behavior, ie, more people are going to make Google
your queries. Therefore, it is important to do a job well structured
SEO in Google, which has the possibility of bringing a greater number
of visits to your site. The other search engines come as a
complementary and should not be forgotten.
