I rarely link out based on requests, and, I spend a fair amount of time explaining to my clients why I turn down most of their link requests.
The most recent link-out request I granted gladly. The site admin of a very credible website emailed me with an offer of a guest post/article (with links back to his site) which was to be on-topic for our site and his. Expecting something less than stellar, or not really on-topic, I was astonished to receive an original, unique, beautifully written article wholly appropriate for our site and clientele.
Requests like this one I will grant every time!
And it is a technique that I will use in the future - offer a good value exchange rather than requesting a favor.
