WP Nofollow Categories is a SEO plugin which adds nofollow attribute to all category links throughout the blog. It will also add noindex tag to category page and nofollow author links. This will effectively remove the category pages from SEO point of view.
The goal is to flow the page rank to other pages on your site like posts and tags while avoiding duplicate content issue.

WP Nofollow Categories

Nofollows category links across the site. Adds Noindex to category pages.

No frames removes the browser frames sometimes imposed on your site.
It has become a trend for top sites especially news and content aggregrators to show your site inside a frame (if you see a site toolbar on the top of the page it’s usually using a frame).
Basically the visitor never leaves the site using the frame although they are viewing content created by you. This is done for multiple reasons and one is to improve the metrics of the site using the frame as ‘visitor time on site’ will improve only for the site using the frame and not you.
Purpose of No Frames plugin is to detect these cases and break your site free from the shackles of the frame, thus presenting the user with your full page.
This not only improves your visitor experience but your site metrics as well.
