Basically I have 4 options to submit them to ezinearticles:
1. Submit them all under one account on the same day
2. Create 10 accounts and submit only 1 per account, and the rest in 2 days
3. Create 20+ accounts and submit 1 per account on the same day
4. Create 20+ accounts and submit 1 per account, but spread onto a few days
I'd appreciate your experience/insight on bulk submission to ezine, especially articles on the same keyword. Are the extra-cautious steps worth their time?
