Another thing that works very well for me, which I really need to do a lot more of, is when instead of creating a blog post to promote one sponsor, you create a post that gives the latest updates within the niche from a number of sponsors. This way instead of saying "Welcome to my cafe, we only sell Jacket Potatoes, would you like one?" it's more like "Welcome to my cafe, we have 10 different meals on the menu, which one would you like today?" so hence you'll bring a lot more sales by using this technique. Here's an example

I've got to start doing one of these each week, need to get up earlier in the morning
