Wordpress Permalinks

What is the best permalink that most search engines like?

Is it:

a) http://www.sugod.com/year/month/post-name

b) http://www.sugod.com/category/post-name

c) http://www.sugod.com/year/month/day/post-name

d) http://www.sugod.com/post-name

Which of these permalink structures do you recommend? And why?

If not, what other permalink structure do you recommend on using?

 

I would say it is (d) in terms of SEO.

 

I prefer (d) too.

 

Thanks you very much.

 

I have seen many popular blogs use (c) and I like it; helps me to easily recognize when the article was written.

Option (d) makes the URL pretty and shorter, good when I try to recommend to friends

I am still learning SEO but for some reasons, I think search engines treat all the same.

 

shorter the URL is, more importance the keyword gets in the URL. i myself prefer just using custom permalink structure with %postname% so the answer would be D

 

I currently use (b( on my wordpress site /%category%/%postname%/ with my content it just works best for me. both (b) and (d) are fine imo. My site ranks just fine. I would not consider myself an SEO guru so it is possible (d) might be better.

 

I would like .html after (d) type permalinks

 

I always have been using D, because they are SEO friendly!
