How to get a keyword in ULR?

Hi guys,
I need some help here. I have seen many people recommend to have keyword in my ULR for better SEO results. However, I have asolutely no clue how to do this? Using wordpress, when I write a new post it automatically gives it the the link http://www.jakobdk.com/?p=49 where the last numer (49) is related to the amounts of posts I have. So I guess my question is how to change /?p=49 to some kind of keyword. Or am I wrong here? Is that what is ment, by "keyword in ULR"? I hope somebody can help me out here.
Thank..

 

You can change that from your blog's options.

 

You would have to need an access to Apache configuration files

 

would that be from the control panel in wordpress?

 

choose first the best keywords for your URL then register your domain or create an html file with your keywords on it.

 

Login in to your wp-admin panel,

select "Options" in top menu

then select "permalinks" , click "Custom, specify below"

Input this " /%postname%/ " exactly as is in the box.

Click update at the bottom and all the posts will be like w ww.website.com/what-my-post-is-about

Then just think carefully about future post titles..

See my site w ww.digitaluktv.com ..... that's how they turn out.

 

Thanks guys!
