Google search engine is one of the most powerful advertising tools out there, as it has the great advantage of targeting almost perfectly your audience. For example, if you are selling tennis, the people you will be able to reach through SEM (Search Engine Marketing) is people looking to … buy tennis.
Now, some believe that the fact of being the first in Google is luck, others believe that you can only get there paying, some even believe that Google does not know what it does and shows results as they come … But no, the truth is much nicer than that, appearing in Google results is possible in two ways only: Google Adwords and Search Engine Optimization.
