By default, WordPress uses web URLs which have question marks and lots of numbers in them, however WordPress offers you the ability to create a custom URL structure for your permalinks and archives.
This is one of the first things you should do when setting up your WordPress pages. To many people, this would seem to obvious to mention, but since I completely forgot to do it when setting up THIS site, I wanted to throw it out there.
Permalinks are really easy to change, and will help you get better indexing from the Search engines. To set your URL’s, click “Permalinks” from the Settings menu. Your options are different combinations of the date and article name or the default setting. I went with a custom route to just include the article title, but not the date. I like the shorter URL, and I don’t feel that dating my articles is that important.
Remember to do this BEFORE you start writing articles. I just saw my pages indexed on Google with the default format. Probably not a big deal, but changing things now is going to break those indexed links. Feel free to learn from my mistakes!
