Hello We are facing a loss in ranking and organic traffic from 3 months on our ecommerce website. Mostly we have lost our ranking on our product pages. These pages are gone in the "omitted results" of google. It all started 3 months ago, when we had to face a duplicate content issue due to a technical priblems with our servers: 2 other domains that we own have been pushed online on google, while they shouldn't have. They have created millions of links to our main domain in a few days, and duplicate version / redirection to our main website. We have fixed this a long time ago now. But in GWT we still see that these domains are bringing links to our main ecommerce. It has dowgraded from 36 millions links to 3 millions.... Even if today there is no link ! We have done a lot of optimizations on site like adding specific content to our most important page, rebuilding the navigation, adding microdatas, adding canonical urls on products pages that we found were very similar (we sell very technical products, and we have products that are very similar. Now we have choosen 1 product to put in canonical each time it was necessary) Bt still our products pages don't rank in google. They stay in the "omitted results". Before they were ranking very well on 1st page of google's results. And we have noticed that some adswe put on ads listing websites are now well ranked in the google's results!... Like if the ads were having more authority on the subject than our own webpages... We started to delete some of these ads. But it's not always possible. And 2-3 of them are still online. Any advice to get our most important webpages at the top on the google's results back? Regards
