One fragment of this blog:
Backlinking to your partner’s relevant pages from within your new articles can do wonders for their Google rankings, and you can also benefit when they return a link.
Just remember to keep it clean and natural, as Google’s Penguin update from last August has massively increased the search engine’s ability to identify unnatural and low-quality reciprocal linking patterns.
The other kind of mentions that I like are those that come through Thank you pages.
Your readers get (or at least should get) to a Thank you page after they register, login, subscribe to your newsletter, or perform any other desired goal.
Imagine how beneficial it could be for you and your partner if you mentioned each other’s blogs as a recommendation each time a user completes such a goal.
