Welcome to the Q&A Forum

Dear all, To begin, english is not my native language, so I'm very sorry if I make some mistake. On the 23th march 2012, Panda penalized my website (a coupon website) Avec-Reduction (dot com for the url). At this date, I have lost more than 70% of my traffic. The structure of the website was like an e-commerce website. Categories -> merchant page -> coupon page. The content was to thin for Google, I'm agree wit that. So, in may, I have made a new version. Here you can see the most important modifications : A smallest header (-100px height). 2 columns website (the oldest website had 3 columns) I have deleted the category menu with the list of all categories and the alphabetical menu. less ads on the website (since few days I have also deleted the 2 adense blocks) The coupons was promoted with the thumbs of the merchant on the home listing. Now I have few top lists in text only. I have deleted all the categories pages (one page by category of merchant, with the listing of all the merchants of the category). Now I have only one page for this. Same thing with the alphabetical pages. All these deleted pages have a 301 redirect. The 2 new pages (categorie page and alphabetical page)  are on noindex. I have deleted all the promo codes pages, all the coupons are now on the merchant page (301 redirect used). I have create an anti-spam system for the review codes (I have a lot of spam on these forms, even if I cleaned every day/2days). Now, I have no spam. Visitors have now the possibility to put a note and a review for each merchant. This fonctionality is new, so not a lot of reviews for the moment. All the merchants pages without promo codes have a noindex on the robot tag. Since july, I have the possibility to use the "title" of each promo code. I can personnalised the promo code. On the same time, to have more content, I have the possibility to add sales or great promos for each merchants, not only promo codes. Affiliate links are created on JS which open a new window (a redirect page with noindex). That's the end of the most important changes on my website. I have a better speed page (/2 since july) because I have optimized my images, CSS, JS... At the end of july, I had health problem and the website has no update until the first days of october. Now, the website is updated every day, but between july and october I have no panda recovery. I have no duplicate content, I try to add the most content I can. So I don't understand why Google Panda penalized me again and again. Some of my competitors have a lot of keyword stuffing (4, 5, 6, ... 10 lines of KS on each merchant pages). Some of them have only affiliate merchants, automatic script to put coupons on websites), few "same" websites... I have less than 30% of affiliated merchant, I validate all the coupons or promo manually, I personalized all my coupons... So I don't understand what to do. I will appreciate all help. If you see problems on my wesite or if you know tips to have a panda recovery, I will be very happy to have informations. Many thanks for all. Sincerely, Florent
