Some questions about ser
1. I've made i think more than 100 youtube projects until now and every time i used the articles from http://eg.radioworldwide.org/. The problem is that this site has only 4-5 articles then the articles will start to repeat, also i'm not the only one using this site. I spin the article of course using http://bestfreespinner.com/ but i think it's not enough, the articles may repeat. So my question is should i search for new articles every time i make a project or for youtube that articles that i'm using now are fine?
2. The articles must contain the keyword that i'm trying to rank and be about the keyword that i'm trying to rank or the articles can be about anything, some meaningless words, the only rule is that it must be unique? Same with the titles.
