alright let's say i go and find hundreds of blogger blogs. like potatoes.blogger.com ham.blogger.com ilovelamp.blogger.com and i go to these blogs, and comment on their articles with my link intact. do each of these blogs count as a new backlink?
They wouldn't count anyway as links in comments in blogger (as in most blogs) will be nofollow. You need to find dofollow blogs if you want your in comment links to count
Yes, they count as different backlinks. Backlinks from different pages are different backlinks despite of the domain or hosting site.
