Hi, I am about to go ahead with manual article submission service, they charge 20$ for 250 directory submission. I am bit confused its really a worthy investment? its will really build my back links and give traffic. Although my big concern is submitting same article to 250 article sites, in Google view it will treat as duplicate content..right? Please share your suggestions and experience.
If possible submit unique articles to these directories. I have tried submitting one article to 500 directories many times. No penalties. But I see only 50-60 of them in results because rest of them are filtered out.
