Way #1. Spin original article 1 time (to get extra one unique article) and submit it to about 10 articles catalogs at one time (when it is still unique).
Way #2. Spin original article 10 times (for each catalog) and submit unique one to each catalog.
Of course, approach 2 is obviously better, but it is more cost-consuming as well. My question is to ask if there are real reasons to do it by way #2, or first approach is still working good for article marketers?
