I built my site about 70 days ago and I was on the first page for more than one month for my primary keyword. I had made my first sale.
Besides, my other keywords were going rapidly up to the first page.
All the content on my site is original and written by good,native speakers. Plus all my articles and product reviews are about 1500 words long.
I never bought any backlinks from anyone. I never participated in a link exchange activity. I even didn't commend on a single blog
I only bookmarked my posts on popular social bookmarking sites,uploaded two of my articles to 8-10 document sharing sites and created a squidoo lens to get backlinks.
Now, my traffic has decreased by 90 percent and my site is still nowhere on Google.
I'm very desperate...
