Rotating advertisements and Google penalty – OIOpublisher case

I am convinced that rotating advertisements can generate a Google penalty.

I have installed on a wordpress website OIOpublisher which allows to have rotating advertisements. I have added a leaderboard at the top of the website. I added 2 ads. One was a link with an “img src” and a nofollow and the second one was an iframe. the OIOpublisher plugin loaded the two ads intermittently. Consequently, when I went to google search console and clicked on “fetch as google”, there were 2 different views on the rendering page. The googlebot window showed one advertisement. The visitor window shows the second advertisement. However, in the google webmaster guidelines, it is forbidden to serve a different content to Googlebot and visitors.  For example, it is forbidden to show a text to visitors and hide it from Googlebot. By the past, one of my websites has been penalized for serving a different content to Googlebot.

Then, few weeks after installing OIOpublisher on my website, a massive drop of traffic occurred. Of course, I could have used the OIOpublisher plugin and display only one advertisement.

I haven’t done anything else special. So, I think the rotating advertisements were responsible for the google traffic drop.
