HOW I DOUBLED Adsense Income on my website with simple PHP script http://www.adsenseninja.com/mobile/ So I bought a website in Jun 2016 for $6700, from a domain/website broker I met couple of years ago on Flippa. The site runs on WordPress, with custom responsive theme. Last month before I bought this site it was making $300/month. I improved this income to $600/month right after buying it (doubling my RPM), by doing AdSense optimization, that I show in this video and explain on my blog: http://www.adsenseninja.com/?yt2x You can find PHP scripts that I use, and Mobile optimization techniques here: http://www.adsenseninja.com/mobile/ WHAT I DID To Double AdSense Income: Site was using Responsive Ad at the top, and I switched it for 2 fixed size ads - one for Desktop (670x280 pixels) and one for Mobile (300x230 pixels). Both ads are "Custom Size". Basically, because of responsive ad, the conversion of clicks on ads was VERY low. By showing bigger ads, I improved conversions. I then used my FREE Mobile Ad Switcher PHP Script to show either 670x280 ad for desktop users or 300x230 for mobile users, based on User-Agent of the browser. Get Mobile Ad Switcher PHP Script for free here: http://www.adsenseninja.com/mobile-ad-switcher/ How this works: if iPhone user comes to my site, my script knows its iPhone by User-Agent (99.99% of users won't even consider faking iPhone user agent!). Then using simple IF/ELSE statement in PHP, my site shows either Desktop or Mobile ad size. By contrast - old Responsive ad would often show 300x50px mobile banner or 468x60 desktop banner, which had much lower Cost per Click (CPC) and Click Through Rate (CTR), and effectively lower RPM Why I think Responsive Ads suck: http://www.adsenseninja.com/responsive-ads-bad/ Since my traffic is 85% mobile, this simple change from responsive to fixed size, helped me improve income by 104% from May 2016 to June 2016 (I bought site on June 2nd). In the same period, traffic only went up by 3.22% due to a massive spike in end of Jun. Otherwise, traffic actually went down. Now this site's earnings are up over $1000 / mo, with increase in traffic that began in August 2016. In this video you will see all the proof screenshots in this video.
