In most cases, the promotion of the site on their own begins with a list of keywords that describe the chosen niche. The more will be this list, the higher the chances that a certain query resource will shoot. Of course, when performing this task should be based on the data of the relevant services (Google Adwords, Yandex Wordstat). They provide information on how often the selected key phrase and related queries were used during the last month. Queries that occur very rarely, it is better to ignore - they are unlikely to bring many visitors and will only take away your time and resources. But also on high-frequency should not be at first, especially if the niche is frankly commercial with high competition.
If you use the promotion of sites with their own hands, the level of competition can be found out by simply tracking the top 10 sites in the top 10 sites for specific key phrases. If this is a large network resources - it is obvious that your chances of getting to the top of the output will be small.
