Плагин Robots Meta для WordPress

Subpages of the homepage
Prevent the search engines from indexing your subpages, if you want them to only index your category and / or tag archives.

Author archives
By default, WordPress creates author archives for each user, usually available under /author/username. If you have sufficient other archives, or yours is a one person blog, there’s no need and you can best disable them or prevent search engines from indexing them.

Date-based archives
If you want to offer your users the option of crawling your site by date, but have ample other ways for the search engines to find the content on your site, I highly encourage you to prevent your date-based archives from being indexed.

Category archives
If you’re using tags as your only way of structure on your site, you would probably be better off when you prevent your categories from being indexed.

Tag archives
Read the categories explanation above for categories and switch the words category and tag around

Add noarchive meta tag
Prevents archive.org and Google from putting copies of your pages into their archive/cache.to put copies of your pages into their archive/cache.

Nofollow category listings on pages

Nofollow category listings on single posts
If you’re showing a category listing on all your single posts and pages, you’re «leaking» quite a bit of PageRank towards these pages, whereas you probably want your single posts to rank. To prevent that from happening, check the two boxes above, and you will nofollow all the links to your categories from single posts and/or pages.

Nofollow outbound links on the frontpage
If you want to keep the link-juice on your front page to yourself, enable this, and you will only pass link-juice from your post pages.

Nofollow the links to your tag pages
If you’ve decided to keep your tag pages from being indexed, you might as well stop throwing link-juice at them on each post…

Nofollow login and registration links
This might have happened to you: logging in to your admin panel to notice that it has become PR6… Nofollow those admin and login links, there’s no use flowing PageRank to those pages!

Nofollow comments links
Simple way to decrease the number of links on your pages: nofollow all the links pointing to comment sections.

Replace the Meta Widget with a nofollowed one
By default the Meta widget links to your RSS feeds and to WordPress.org with a follow link, this will replace that widget by a custom one in which all these links are nofollowed.
