First of all,
it simply is not possible to guarantee placement on the first page
of search results, for a variety of reasons. One
reason is because the criteria or "algorithms" that search
engines use to calculate rankings are constantly changing, and even
the most well-informed SEO guru is not going to instantly know about
these changes and how to change your site to take advantage of them.
Another reason
why "guaranteed first page rank" impossible is the fact
that your ranking is affected by many things that have nothing to
do with your site's optimization. For example, there is your competition.
Other sites, possibly many others depending on the subject matter
your site deals with, may be just as well-optimized as yours is.
And even non-optimized sites can rank better than your extensively
optimized site for many reasons, such as because they have been
around a long time, are very large, and they get a lot of traffic.
Also, while
it is true that a very high ranking (but still with no first-page
guarantee) can often be achieved, it can only be done by focusing
the optimization on just one exact search phrase that you hope a
searcher will use. If your site is optimized in this way and your
searcher uses some other search phrase, your site can perform quite
poorly. And because different search engines use different algorithms,
this best possible optimization can only be for one specific engine
such as Google and will not work so well for another such as Yahoo.
Finally, maximum optimization can detract from the readability of
your site, making the content look like it is written for the search
engines to find rather than for real people to read. You certainly
don't want people to easily find your site, only to quickly leave
it because of bad content!
In conclusion,
steer clear of SEO websites that promise "guaranteed first
page rank." A guarantee is not possible because of ever-changing
ranking algorithms and factors beyond the optimizer's control. Trying
to get such a ranking is not advisable in any case because of the
downsides of poorer performance for all but one phrase and engine,
and poor readability. Optimizers that make promises like this are
either dishonest or not very good optimizers.
