I run a number of websites and over the last few years i’ve tested every size of ad unit, every format, location and colour option possible and today i reveal which adsense unit has worked the best for me. This is 3 years worth of data!
By far my best performing ad size has been my 336 x 280, the large rectangle. It has bought me over 40% of my adsense revenue over the last few years. Its out performed all other sizes by at least 3 times.

As far as positioning goes, you need to keep one of these ad units above the fold of your web page. Keep it on its own line if you can or wrap to the right or left. Dont leave anymore than 5 pixels of spare space around the ad.
So what about colour scheme? should you blend your ads or contrast? By far my most revenue came from ad units that blended in. Those that contrasted put people off clicking them.
What have you found worked best for you? Are you checking regularly?

Making a few simple changes today could see you Ad revenue grow dramatically without having to increase your visitors. Oh and that reminds me, visitors from natural search return more revenue per click. So focus your efforts on natural SEO if you want to earn more. I found social media traffic was either low earning or the clicks got cancelled.

While the Email Subscription in AdWords Beta test is still in progress, Google retains the data after an email address is submitted through the extension. Once you’re signed on and approved you can ask them to send you the data in real time via instant notification to your Google account, or in a mass excel sheet after certain periods. This will cause problems as when you import the data into your current email software / solution you may need to get double opt in reconfirmed, which will prove a pain and you will probably find most people wont want to resubscribe. Google have however added a privacy link next to the email signup box.
When you look at the successful affiliate marketers out there or the Make Money Online Guru’s they all use the power of a large email subscriber list. They also share these massive lists between each other. But how do they grow these phenomenally large lists? It’s quite simple, but it takes effort! They give something away FREE.
