Top 5 Best Practices for Ad Placement
Finding the best Adsense banner sizes is one thing and placing your ads at the right placements is another most important thing. Here are some of the best practices for ad placement to increase your earnings.
1. Learn how to balance content and ads
Make your ads look natural. Don’t place ads on irrelevant places. Your ads should always supplement the content on your site (and not the other way around).
For example, if your site offers free downloads such as eBooks, mp3 files, stock free images and so on, make sure the download links are above the fold and easy to find.
Consider using native ad units if you want to make your ads look natural and that’s how you can easily balance your content and ads. That way, you can also increase your ad earnings without hurting the user experience.
2. Less is more
Sometimes, less is more. It’s true for ad placement too. Don’t place too many ads. If your website users can’t find what they’re looking for, they may go elsewhere.
It can kill your conversions and also lead to high website bounce rate (ultimately bad for your search rankings). So be thoughtful and try to put a combination of ad units, link units and search boxes on each page of your site.
3. Use mobile responsive ad units
Here are the mobile Adsense ad units that are currently available.
- 300 x 250 ad unit
- 320 x 50 ad unit
- 320 x 100 ad unit
- 250 x 250 ad unit
- 200 x 200 ad unit
If you’re getting a lot of traffic to your sites from mobile devices (or even tablets), you should definitely consider using mobile responsive ad units which are mentioned above.
The great thing about using these responsive ad units is that they automatically adjust their size, appearance including the ad format to fit just about any available ad space.
Above all, these responsive display ad units leaves the work of testing and optimization to Google and ultimately enables you to focus on better ad performance to generate more click through rates and income.
4. Give importance to showing content more than ads
One of the biggest mistakes most people make while placing ad banners on their site is they suppress their content. They give more importance to placing ads all over their content.
It ultimately leads to bad user experience, higher bounce rates and lower Adsense earnings.
Have a look at the following illustration to understand it better.
As you can see above, site layouts that highlight content yields better results (in terms of user experience, CTR, revenue and so on) whereas site layout that pushed content below the fold produces bad results. So give more emphasis to content, not ads.
5. Try heatmap tools
Last but not least, give a try to heatmap tools as they help you understand your website’s user behaviour.
Using heatmap tools like Crazy Egg can really help you with the following things.
- Find out how often your website users visit a page
- Find out what kind of content is most popular on your site
- Find out how your website users are navigating your site (from entry to exit)
Based on the above things, you can easily experiment with your ad units and placements to improve your overall conversion rates and CTR.
