Why does SEO not bring results?

You should understand that this is due to the fact that promotion in SEO is a race and your competitors do not sit still. Therefore, it is impossible to guarantee a result. Let's imagine that your budget for SEO and external optimization $ 1000, and your competitors spend $ 2000 on it. If you use the same strategy, you will lose. No one can know the competitors' strategy, so can not guarantee the result.

Unfortunately, no one knows exactly what criteria are used by search engines to evaluate sites, how the algorithm selects one site and rejects another. SEO specialists rely on experience, their own and borrowed from colleagues assumptions about the behavior of algorithms. But these algorithms are constantly changing. The only thing that the agency can guarantee with certainty: to fulfill the undertaken obligations in time and with the highest possible quality. I am working with an SEO company "To-The-TOP!" , and so far there have been no questions about the quality of their work.
