Permalinks

In WordPress, permalinks are optional, but are required for all SEO work.

In short, all SEO WordPress blogs should have the permalinks feature turned on. Somebody should be asking WordPress why at this point-in-time, permalinks are not the default option? Everybody should be using them.

Permalinks is a very convoluted way of saying that you want your urls to be readable, or in other words to contain important keywords.
