This plugin allows you to intelligently insert ads (like Adsense) before and after your post content based on post wordcount, post date, or other feat
Smart Ads automatically inserts advertisements like Google's Adsense above and below your post content. These advertisements are only visible when viewing a single post (single.php or page.php). Since it doesn't make sense to fill small posts with ads, users can set a "Wordcount" minimum for their advertisements. Smart Ads will only insert advertisements into posts that meet or exceed the desired Wordcount. Also, to ensure that new content remains fresh, users can choose to only place ads on posts that are over a certain amount of days old. Advertisements can be manually disabled on a post-by-post basis while writing a post, by category, or for registered blog members.
Users can also insert custom ads into their posts or pages by using the Smart Ads shortcode. Just enter [smartads] anywhere in your post or pages to display your custom ad. Custom ads are not affected by the Wordcount or date minimum requirements and can be toggled to show on the index page or only shown when in single post view.
