performance - Wordpress: Your favorite permalinks structure - efficient / seo friendly -

i using wordpress permalink format: /year/month/postname in wordpress blog. of blog posts write tutorials / how-tos. doesn't make sense organize on based of date.

i know comments / suggestions on how organize urls in wordpress. know wordpress not recommended permalink based on category name: /category/postname, organize urls based on categories without affecting blob performance.

• /year/month/postname -> good
• /postid/postname -> good
• /category/postname -> bad
• /author/postname -> bad

please give feedback on favorite permalink structure keeping both performance , seo in mind.

thanks

it depends on blog content.

by default 90% go simple /postname/ only

if year or month important blog (which isn't case), add year or month it. never add date unless it's important google search (maybe news blogs etc.).

it's important keep url short. , important have keywords in url. what's needed, , rid of not. that's general point of view on this.
