Archiving:

Set your archiving to daily if you post every day, or weekly if you only post every few days. If you post every day daily is the best way to go, because it gives the search engines more unique pages to crawl and index. More unique content means more traffic to your blog and more clicks on your AdSense ads (I’ll get to adding your AdSense to the template in a bit).If you don’t do a daily archive (and maybe even if you do), enable post pages so that each post will still have its own unique page even if multiple posts appear on the same archive page. Having multiple posts on one archive page is not a bad thing if you have post pages enabled, since the posts tied all together make for yet another unique page on the blog.
