Is it better to post articles on one resource or on different ones?

Question

Search Engine Optimization

Good afternoon!
Tell me, please, there are several articles, how best to place them on the link exchange?
There are two options:
1. Place all articles on one resource (website - donar)
2. Place all articles on different resources
*All resources are of the same quality

Answer 1

Link mass should be diverse. So it is better to place on different donors.
