Hi.
On early Saturday morning I changed the design of all the webpages of my site, to convert them into responsive ones. Around 40% of my visits are from mobile devices, and the change triggered a 10% increment of visits (with respect to the last weekends, it may be circumstantial) and an increment of the ratio 'pages per visit', from 2.1 to 2.5, with respect to the average of the last year (this is cool and, with no doubt, a consequence of the change).
However, the income from AdSense during these last two days dropped 10%, with respect to the average of the weekends of the last years.
I switched the design of each one of the ads, to convert each one into a responsive one (I simply chose the option "responsive" within AdSense control panel), leaving them on the same placement, within the webpage, as before. As a consequence of this, Google decides the dimensions of the ads, and when you visit the webpages through a Desktop device, these ads are long (maybe 728x90 leaderboard). And if you visit them through a mobile device, they are square (maybe 250x250).
Within the previous design, most of my ads were square ones, and wondered if it was a good idea to switch them to responsive ads. I understood that it could be wise to let Google decide the size of the ads: they have more understanding of the user experience and, of course, they would try to optimize the income. However, I am not sure of that.
I would like to hear other experiences. Would it be a good idea to leave my big, square ads on the Desktop design, but leave the responsive ones on the Mobile design? Should I wait to collect more data because this is a circumstantial drop of this weekend?
Thank you very much in advance.
