visiting yourself once in a while is fine and having larger traffic with many impressions is fine as well as long as you are not breaking adsense's TOS on how you are acquiring such traffic. However also keep in mind if you ahve many impressions but very low clicks, your earning may drop.
This was my main concern, i'm basically just starting to get members, but i'm also on it all the time making adjustments and viewing whats going on. Thanks for the replies guys.
also track where the traffic is coming form because even though your earning can effect, it effects more if you have visitors from "ad non convertable" zones/countries.
I think it can lower CTR and i would not do it alot. A few times is no big deal but hundreds a day would be.
I think after a couple of visits from the same person google probably ignoring the person's visits for a period of time..
visiting your adsense page alot is not good and may be they will detect your impressions and banned you!
Try to avoid going to it one hundred times in a day. This usually boosts up impressions and Google will sometime question what is actually going on and sometimes make some of your clicks not count.
I think it is not a problem. But avoid this issue just visit only 1 or 2 times for every 2 or 3 hours
