Thank you for your answer, so you 're telling me that when i have a lot of people buying my items they become more relevant at the top of the pages, so the fact that they would just click to open my item's page is not enough for that ?
ok i've just read all that and it doesn't answer my question. when i sell something, this item get on top of the searches by people purchasing a lot this item or by people clicking a lot on this item ?
