My experience is: Both require unique content. My articles were rejected by AM after I post/published them to ezine.

I have written many articles, and submitted in enzine, and got approved. It has really helped me to gain rankings and traffic as well. Go for unique contents, if you can't, hire a professional write to do the job.

Cheers!

But AM does submit to ezine right? So is there any point in submitting to ezine now that I am using AM?

You should submit unique articles when submitting, especially if you are wanting you backlinks to count. All your 'plr' may be making it onto the net, but check a little further down the line and you'll probably notice that they have been dropped into the supplemental index. That index doesn't give any weight to your backlinks.

Trust me. Re-write and submit and you'll see the difference.
