To obtain a website is one thing, but to bring visitors to the website is another equally important issue. Besides, what is the meaning of having a website if no one visits it? If we want to have visitors and actual yield from a website, we must set as our objective to rank it in the first page or at least, in the second page of the organic results of a search engine. (The organic results are those shown in the results of search engine naturally and not by Ads.)
According to official statistics, in about 70% of searches for a keyword, the users first visits the websites that are within the first 10 results. Then another 10-15% will continue to the second page and if they do not find what they're looking into those 20 results, they re-search with different keywords. In simple words the main target is to help a website rank in the first 20 organic results or even better in the first 10 results.
