Smart Ads automatically inserts advertisements like Google 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. Click here to download.
