Native ads are great...except when they're not.
Native advertising has brought a lot of value to content publishers, but on pages where users have strong commercial intent, these ads are often lacking.
Native ads typically target at the site level, not the page level, because there isn't enough ad inventory to closely target your users' interests.
With sensational images and copy, native ads often distract users, even leading them away to your competitors.
When you show ads that don't match your users' interests, you're missing a big opportunity to make more money from your site.
What you get with other native-ad providers...rarely relevant, always tasteless.
