Main advantages of SEO.
Research shows that some
researchers never click on the sponsored listings and others don't
realize that these links are paid for. Approximately 80% of clicks are
on natural listings and 20% on paid listings.
A principal benefit
of SEO (Search Engine Optimization) is its cost-effectiveness as there is no payment to the search
engine for being placed within it. This is very important for the
'search head', high volume low intent searches which are expensive in
paid search.
The cost of SEO is relatively fixed, independent of
click volume. After initial optimization costs, the cost per click
reduces whilst paid search is essentially a variable cost.
Thus
there are no media costs although resources are necessary for analysis
of key phrases and to complete optimization on the website pages.
Together
with paid-search it offers a very targeted audience, visitors referred
by SEO will only visit your site if they are seeking specific
information on your products or related content.
Disadvantages of SEO.
The
major challenge of SEO is that there are billions of pages in the
search engine indexes and your position in the SERPS is dependent on a
constantly changing algorithm which is not published. Therefore, making
your pages visible can require specialist knowledge, constant monitoring
and the the ability to respond.
Consequently, the biggest disadvantage of SEO is lack of control. You are at the mercy of the algorithm.
There
are other possible issues. Sometimes competitors or affiliates may use
less ethical black hat techniques, thereby putting you at a big
disadvantage.
Also, in very competitive sectors, it can be hard to
get listed in the top few results for competitive phrases and this is
when expensive pay-per-click may have to be used.
Because of this
lack of visibility it can be hard to make a sound business case for SEO,
although it is strikingly obvious of the benefits to most companies of
the number one position on Google.
It is quite impossible to
predict positions and click volumes from SEO, because future changes to
the algorithm are unknown. Likewise you cannot monitor or predict
competitor activity.
it is impossible to predict the level of return
So, for a given investment it is impossible
to predict the level of return for your dollar, pound or euro or to
estimate the likely return compared to paid-search or other, more
traditional methods of advertising, where more accurate estimates are
possible.
This is not to say that estimates of long-term returns
from SEO cannot be made. Always bear in mind that SEO is a long-term
strategy and that a long-term cost/benefit analysis is needed.
