I assume this question is being asked in terms of "are there SEO negatives attached to doing..."?
If that's the case, if there is a benefit to your users (as there is in this case) to you doing something, completely forget about the SEO impacts of it. Consider SEO when it's a toss of a coin decision or where it has no negative impacts on a call, but when there's a clear benefit to your users to do something, do it.
(In terms of SEO, and for the benefit of your users, just be sure not to link to spammy/questionable sites)
