Hi, I would like to ask you guys what have you done for your datafeed sites and make google free traffic keep coming. I have been an affiliate for 2 years, and made some datafeed sites. I made all datafeed sites using php/mysql, and it all looks like html pages. meta tag, file name using keywords. put some coupons. I try to change products' description too, and make it not duplicate content. Then submitted it to directory, search engine, blog... After 2 or 3 months, traffic start coming from google, msn, and yahoo. But I found traffic start to slow down after one month. Then after 2 month or 3 month, traffic almost dead. Do you guys have any idea how come this thing happened? any good idea to keep traffic coming from Search engine? Thanks.
