I don't think you can rearrange adds on hubpages. But there are many ways how to arrange adds on blogs.
First rule is not to bomb blog with adds... one-two add box per page is optimum. Pages with too many adds looks spammy and will effect SERP.
Second thing... position add in a page content and not on the header or footer. That way google knows page content and will use appropriate links. Sidebars are OK but CPC is lower.
Third. Use style for your adds. Background and link color should always match page style.
And as Froch sayed: Never click your own adds. Never tell your friends to clik on them ether. Too many click from the same source will also get you banned from AdSense.
