3, all to be able to query and calculate the flow as the sum of the site search flow obtained from love of Shanghai;
2, by ranking position and to estimate the amount of search keywords of the website of course where the ranking position can get much traffic (get traffic = total search volume * ranking position hits);
so, if we blindly love Shanghai weight data, is likely to miss a lot of good website. For example, some industry websites, the search is small, even if there is a 10-20 ranking in front, because the search is small, so it can not be in love to get good numerical weight in Shanghai.
