When Google algorithms detect a high rate of accidental clicks on ads, arrows can be removed. In this case it is recommended to change ads layout to prevent misleading site visitors. After that the buttons may return in several days.
I understand that and I am looking at reports and noticing much lower text ads being shown all around. I hadnít changed anything on my site layout in the last few months and it has been fine and all of sudden RPM was at least triple or close to that the day before it happened
I lost the arrows two times. First they reappeared after like 1-2 days (after I repositioned the ads). Next time it took a little bit longer like 1 week. Now I make sure all ads have "advertisement" labels and are not in place for misleading clicks.
It's absolutely not a penalty. Penalties are significant.
Some have suggested the missing arrows are a result of having ads too close to txt or each other. I do not agree. If that were true, then missing arrows would not have returned on ads I monitor after having done nothing on my end.
Missing or returning arrows are simply something that happens without any reason. Adsense just does this from time to time.
I believe it was a penalty because I was an abnormally high CTR right before it happened and be free that my site had been fine for months without any changes. Iím just hoping they come back soon because it is affecting my RPM
@Grapetimes - you have received too many accidental clicks on some of your ad units. Try to make them less aggressive and the arrows will come back - it depends from publisher to publisher, from 1 - 20 days or even more.
