Welcome to the Q&A Forum

I'd add product articles/reviews to the list of content for link building.

Thanks Martijn!

Thanks John-

I'm currently running Adwords retargeting (remarketing) campaigns, and just kind of looking to take it to the next level. It's the only solution I have personally used to date. Possibly someone who can also provide creative support and help put together some complex campaigns.

Sure.  While you'll have a link from 1 external RD, you'll still benefit from additional links from that same RD.

Does anyone have any recommendations for Retargeting companies you may have used?

The grunt work of linkbuildign can take a long time. Especially when doing it right. Can Mechanical Turk help me here?
