So if I've got this right, you should just look for long tail keywords related to your niche and build your title around it, and pepper that phrase throughout your article, correct? Should you add other keywords or should you make an effort to really push just the one? Also, is it okay to just rewrite your articles and resubmit? Like is it alright and are there any repercussions to taking an article and just rewriting and resubmitting a week after the last one got accepted, and just doing this over and over again each week with a handful of unique articles?
Yes, rewriting is ok, you can do that. It's up to you how many keywords you want to target per article, but I choose one, because then it's 100% targeted to that specific keyword.
