Long-time lurker, first time poster. Maybe someone will know what's going on here.A few months ago I started this site: Digital-Product-Reviews.com. It's a basic Clickbank affiliate site, but I make the content as unique as possible by describing and reviewing the products in my own words. I'm also willing to give negative reviews to products with a high refund rate and lots of complaints. I'm pretty sure my on-page optimization is good, though I definitely need to work on getting more backlinks. I've been adding 4 or 5 reviews a week and have about 100 so far. Anyway, in mid-April I started getting more traffic, and for the first couple weeks of May I was getting 30-50 visitors a day from the big G. In fact, I was ranking 5th for the keyword, "digital product reviews." Then all of the sudden, on May 17, my traffic started dropping and now it's almost nothing. And my site is nowhere to be found for the keyword, "digital product reviews." I've checked site:digital-product-reviews.com and all my pages are still indexed. I just don't understand why my site would start doing better then abruptly drop like that. Is this the infamous sandbox? Did they change their algorithm on the 16th? Should I just be patient and keep at it? Thanks!
