last a two weeks i try this permalink http://www.blog.com/%post_id%/%postname%/ Code (markup): and is look like http://www.blog.com/53/thetitle/ Code (markup): more shorter and i hope it will be good at SEO
I also choose to use /%postname%/ it's easy, precise, and looks a lot better, plus its very good for search engine rankings, it ranks me higher than when I used category/postname/date, or any other variation...
as long as it ends in %postname%.html it should be fine. Also check out the all in one seo pack and google sitemap plugin
Why... I don't really agree to make wordpress permalink to end with html. For example if you click the "Read More" link it'll look like this. thepostname.html/#more34 like that. Not nice and it fools the SE bots. How if your site is penalize?
an optimal structure is your site/date/post .....thats what i ve been using on my blog and its indexing well
No i think this is not cheat, bcoz title is corelate with content , just make title more appear Thats functions permalink
