Send A 'Thank You for Linking' Email
Always send a 'thank you for linking' email. Avoid smothering your new linker - a few lines are plenty. Do ask if they can think of any ways that your two sites could benefit each other. Also, consider asking this linker to connect with you on Twitter, LinkedIn, FaceBook, etc if you operate profiles on these social media sites.
