It is the "use tags for meta keywords" option. They won't show up in wp-admin, but will show up in the source code of your actual site and to Google.

i think there should be keywords place , but there is not , what you prefer to me ? i know you so busy person , so i tried to solve this problem myself , i tried to use simple tags plugin to auto generate tags for my new and old posts automatically , but it also has problem with new wordpress version 3.0.1 , it not generate tags.
i was thinking i could fine it in pro version to use auto generate tags , but when i can not find in pro , i felt a little sad , i hope you help us about this , thank you
You don't want to use something like the simple tags plugin to auto generate the post tags. You want to create those yourself.
Once you have created post tags (which are separate from meta keywords/tags), your All in One SEO Pack - Pro Version will automatically turn them into meta keywords for you.
if you check what you wrote in the all in one seo pro description it says :
"Generates META tags automatically"
but can you show use where it create tags ? we can not see anything about it . of course i know how to create tags my myself , but my webpage has auto posts plugin and it posts daily 1000+ article . that was why i bought all in one seo pro to create tags automatically . but as you know it not create tags automatically . just fix this
The plugin does not create your META keywords from nothing. It has options to create them automatically from post categories and/or post tags.
it is hard to understand what you mean with tags.
you wrote " Generates META tags automatically " and people wish to use it as auto tag creater for posts .
why you not explain it for people that it is not auto generating wordpress posts tags .
as like me , most people wish to use especially to generate tags and use them as keywords on source of posts .
just fix your plugin toauto generate posts tags or kindly remove your plugin description about " Generates META tags automatically "
WordPress post tags are not the same as META tags. The plugin description does not say anything about creating WordPress post tags.

i deactivated standart version , deleted . i uploaded pro verison , but it shows same standart verson , i can not see " Generates META tags automatically " opition there , i will add screenshot , i hope it works properly
