Hi,
this sounds like quite a nice problem to have to be honest but there are two ways I'd address this.
1: make sure you post is linking through to the page you want to rank that way when google crawl your site they should start to see lots of good content pointing to that page your trying to rank first and give it more weighting, you might also want to look at your site structure to see if you can improve which pages google is seeing as important that way as well.
2: a win is a win why not look at how you are moving users from your post to your "money making" pages, this is a good practice any way as once you've sorted you site structure you'll hopefully start to pick up some nice long tail keywords from your posts.
Thanks
Rufus
