How to protect your content?
I started a new blog few months ago but suddenly I lost my ranking on search engines, I mean my pr was zero but I was on first page for many keywords. I invested a lot of time writing informative review and product details, it all went to waste because my website is in sandbox. I put this question on many forum and seeking serious help; today my site is suffering just because many people copied my content, literally my each review is on 10+other websites. Those who stole my content have good PR( I don't know how they attain it playing unfair games), they copied my content word to work. They just replaced my af link with theirs and using my reviews. Could you please suggest me something? is there any way to protect my content?
Thanks in advance
