The title pretty much says it all. It’s 2 of the most useful AdSense ads tips for bloggers in my opinion. Obtrusive ads have the unnecessary effect of driving away readers after they have found what they needed. Unless you have amazingly great content, the chance of them becoming a loyal reader is rather low when you have ads splashing into their faces – this is not something you want to do to your subscribed readers. On the other hand, you’d want to maximize your AdSense earnings by putting up ads on as many posts as possible.
Ad Injection (WP plugin)
This tiny little plugin, Ad Injection, gets it all. Very useful plugin for you to insert AdSense ads in your blog posts AND set a specific age threshold for the posts to display ads, so freshly published articles won’t have ads to drive your subscribers away. See detailed introduction here: Ad Injection for WordPress.
Just install it from the inventory (upload or install from within your WP administrator panel) and activate it. Go to Settings > Ad Injection > “Random ad (inserted randomly between paragraphs)” and insert your AdSense code there. Depending on how aggressive you are, you can use a variety of ad formats from Google. I used a 468×15 links banner on Health Not. Check out the screenshot below:
By default, Ad Injection inserts a maximum of 2 instances of the Random ad per post. This way, the ads are well blended in the content. What works a few years back with the 336 square ad format on top of the content is gradually dying out in CTR thus click revenues. You should try something new such as this.
Another useful option of the plugin is to set “Only show normal ads on pages older than xx (days) – only for single posts and pages”. This would prove very useful if you want a good balance between ad performance / earnings and user experiences. Only displaying ads on older posts are a pretty good idea for creating a good first impression to those who stumble upon your site.
