I have spend a lot of money on article writing for the projects for which i am doing SEO .
Now i was just thinking that whether i can use those articles again or edit them and resubmit it and do ...
Hey if you submitted it ones then it is ok you can resubmit it buy using different link. But submit it in other articles sites. If you have submitted it in ezinearticles then do not forget to specify the source link.
But do remember do not use article many times because search engine knows the content and recognize it as duplicated content and not give that much power. Search engine always like a fresh content.
