SiteMaps, Priority and SERP's

So I use wordpress for a few of my sites and installed a sitemap plug in. I just noticed that the plug in automatically gave the same priorty to static pages as posts. Do you think this really matters to serch engines what the priority is set at? I increased the priority for static pages to .8 and reduced the posts to .5. Does that make sense? Do you think search engines really care what the priority is set at?

Hello Travis,

i set my mainpage to 1, posts to 0.9. 301 pages (Affilite links) i have excluded from the sitemap. Important static pages i set to 0.9, others to 0.5 or lower.

If you have good content and patience, it can work very well.

It is also very important to use no follow attribute when placing affiliate links in reviews and etc.
