Welcome to the Q&A Forum

Hi all.
I have a website called Hemjakt (http://www.hemjakt.se/) which is a search engine for real estate currently only available on the Swedish market. The application crawl real estate websites and collect all estates on a single searchable application. The site has been released for a few months and have seen a steady growth since release, increasing by 20% weekly up to ~900 visitors per day. 3 days ago, over night, I lost 80% of my traffic. Instead of 900 visitors per day I'm at ~100 visitors per day and when I search for long, specific queries such as "Åsgatan 15, Villa 12 rum i Alsike, Knivsta" ( <adress><house type=""><rooms><area> <city>), I'm now only found on the fifth page. I suspect that I have become a subject of a Google Penalty. How to get out of this mess?</city></rooms></house></adress> Just like all search engines or applications, I do crawl other websites and scrape their content. My content is ~90% unique from the source material and I do add user value by giving them the possibility to compare houses, get ton of more data to compare pricing and history, giving them extra functionalities that source site do not offer and so on. My analytics data show good user engagement. Here is one example of a Source page and a page at my site:
Source: http://www.hemnet.se/bostad/villa-12rum-alsike-knivsta-kommun-asgatan-15-6200964
My Site: http://www.hemjakt.se/bostad/55860-asgatan-15/ So: How do I actually confirm that this is the reason I lost my traffic? When I search for my branded query, I still get result. Also I'm still indexed by Google. If I am penalized. I'm not attempting to do anything Black Hat and I really believe that the app gives a lot of value to the users. What tweaks or suggestions do you have to changes of the application, to be able to continue running the service in a way that Google is fine with?
