I've been doing lots of experiments to boost my Adsense earnings. One trick I use that has increased by click through rate quite a bit is boosting DWELL TIME. This is when your visitors STAY on your site for more than 30 seconds. The longer they hang around, the higher the chance they'll click on an ad.
Here is the visit length breakdown before I ran my experiments. Note that the green section denotes visitors who are at my site for 30 seconds or less.
Here is the result after the changes I did:
Here are the list of changes I did that boosted dwell time
Step 1: Write very LONG POSTS - 1500 words is good. This length can be easily broken into smaller chunks (see later steps below) and is also good for SEO. SEO Proof? See

Step 2: Put subheadings into your long content. The subheadings must be NATURAL or THEMATIC breaks within the content. You can't just break up the content randomly.
Step 3: Put NEXT PAGE wp tags before each subheading. This breaks up your 1 page post into multiple pages. For my experiments, I noticed that breaks of 100 to 250 words work well BUT it depends on your NICHE. I am in a niche that loves spoonfeeding so I get away with 100 words per page. However, if your niche requires something larger, try 250.
Step 4: Write one sentence per line. Here's the kicker: format your content to be read. The easier it is for the reader to read your stuff, the longer they'll stay around.
Step 5: Write an emotional trigger line per page that PUSHES the reader to click the next page link and see more content.
There ya have it. My step by step approach for boosting your Adsense earnings by increasing your dwell time and decreasing your bounce rate.
