Hi, I am building an eCommerce website with more than 4000 products on it. Its very difficult for me to write content for each product page. I am just replacing keywords on the product pages and that's all. The duplication between two pages is found to be around 90%. Now, i have to options: 1- Write thin content to avoid duplication. 2- Do extensive keyword stuffing to make them unique. What would you recommend, and please also suggest some techniques if you have. Thanks in advance!
