Why do i not receive google traffic?

[rxesiv]

over the 4-5 months i have published over 3000 unique articles which i have payed well over 10 000usd for, but i still only receive about 20 google visitors a day for that content. i uploaded the 3000 articles after i 301 redirected the old site to a a new domain (old site had 1000 articles, and at least 300visits from google a day), and all the old conetnt receives the traffic fine (301 redirect is working 100percent now and pr went from 0 to 3pr) articles are also good ranging from 400-800 words. 90 percent of them are indexed by google, most of them have been bookmarked to digg reddit etc website domain is over 10 years old - alltopics.com  why google doesnt send me the traffic i deserve?

The site looks really low-quality to me right now (not sure what it looked like two months ago), with lots of ads and just snippets of content from elsewhere. Ask yourself if this site ads value to the user for their particular query. I couldn't find any pages that did.

Quality issues perhaps - I've only looked at a couple of articles but they're not very well written at all. If I came to your site through Google searching for visa to ukraine I wouldn't be happy with the result - unfortunately for you from what I've seen your site doesn't deserve the traffic from Google. 

So as EGOL says, they might just be spun articles, and not really 'unique' as you say...

Maybe you didn't pay enough to get good articles that are genuinely original and not spun.
