Adds the rel="nofollow" to links in posts within a selected category. Useful for sponsored posts.
NoLiP plugin was originally written to help "paid bloggers" add nofollow to links in sponsored post after a set amount of days. With so many "Paid to Blog" companies such as PayPerPost, ReviewMe and SponsoredReviews, there are a lot bloggers doing sponsored posts. Google will penalize blogs that do not use no-follow, this will help you get around this by meeting Google's terms and Sponsor's terms.
Absolutely! It is ok to add nofollow to links after 30 days. But if the advertisers finds out that you've added nofollow to their links, they have the right to place a BAN on you. So, use it at your own risk!
That depends on Terms of Service. You should always read their Terms of Service/Rules & Regulations to see whether they have any specific rules about nofollow.
nofollow is an HTML attribute value used to instruct some search engines that a hyperlink should not influence the link target's ranking in the search engine's index. It is intended to reduce the effectiveness of certain types of search engine spam, thereby improving the quality of search engine results.
This plugin works on the fly (dynamically) and does not alter the wp_posts database table structure
