I have a client in a niche building industry that provides 4 different services to them. She has provided me with a list of 131 past clients of hers that she wants hyperlinked on her site to theirs. The logic is that a lot of these clients are heavy hitters and quite impressive to their peers so the links will be reinforcing my client's value.
Is there a best practice for determining whether the link should be follow/no follow? Should I be checking the client's site's spam score, page rank, anything else? Some of these 131 links will be duplicated due to the client performing more than one service for them.
