Good question ...
1 On your blog you can to promote TripleClicks and SFI together. In the blog include your gateweys urls.
2 If you want to create a separate blog for TripleClicks where you can to promote the ECA, Pricebenders etc. ... And of course a special blog for SFI, where are you going to write more about the job and specify your gateweys of SFI.
