Technical errors in the development of the site, low level of internal optimization, lack of user-friendly interface, low download speed can seriously reduce the position of the resource in the search results. Often this leads to a hang in the depth of the issuance of targeted requests without any prospects for growth. It even happens that the site remains hanging on the 11-12th line, and it lacks some smallness to appear on the TOP-10 page.
