用目录名设置成文章的META KEYWORDS
Use Categories for META keywords
Check this if you want your categories for a given post used as the META keywords for this post (in addition to any keywords you specify on the post edit page).
Use Category Description as Title
This is for using the category description, and only the pure category description, as the title for category pages. If this is checked and there is no category description, the Wordpress default will be used.
Use noindex for Categories
Check this for excluding category pages from being crawled. Useful for avoiding duplicate content.
Use noindex for Archives
Check this for excluding archive pages from being crawled. Useful for avoiding duplicate content.
Auto-Generate Meta Descriptions
Check this and your META descriptions will get autogenerated if there’s no excerpt.
Max Number of Words in Auto-Generated Descriptions
Set this to another value than the internal default of 25 if you want your auto generated META descriptions shorteror longer.
