Promotion consists of several stages. First, a specialist collects all the data about the resource they are going to work with. Based on the current positions, services and goods, a promotion strategy is created. Then the search for technical deficiencies and errors in the code - they slow down the loading of the site.
After that, experts conduct internal optimization - upgrading all parts of the resource, starting from the structure and ending with the addresses of the pages. The final stage - external optimization, when the work goes to the reputation of the site. This is mainly reference mass from other sites and natural transitions.
