I have a question about backlinks from site A to another site B: Does it make a difference if there is let's say one backlink from A to B or ten backlinks? Is it the more the better? Suppose I make 10 links with anchor-texts like "dog-animal", "cat-animal", "goat-animal" etc. Does it count 10 times for the keyword "animal"? And does it count for all the 10 different animals mentioned in these links?
