Here's how I do it.
Find excellent keywords, especially long tail keywords. Target them on around 15 high quality blogs with great articles on dating.
For example the keyword "legitimate dating sites" , you would roll out articles entitled Legitimate Dating Sites with an article warning people about the dangers of some dating sites and how to choose the right one, you would then in the same article mention your two dating sponsors (good to give people choice) as legitimate dating sites which can be trusted. So the start of the article is informative, the second part of the article is like a mini review with links to your dating sites. Link to your money site using each of these 15 + blogs / deep links into your money site which again has reviews - and you will gain PR2+ in no time on the money site.
(Edit: for some keyword terms I might have 2 or 3 of my blogs on the front page of a particular keyword search which gives me a higher chance of gaining a click through from the SERPs. There are some instances where I have 1, 2 & 3 in the search results which gives you most of the search traffic for that long tail keyword right there)
On the money site have reviews of several dating sites with nice star/review boxes linking to your sponsors.
This strategy works because each time someone hits your network blogs there is a chance they will hit the dating sponsor, however the real purpose of them is to boost your money site which for many keyword terms will rank extremely well.
