CTR has gone WAY down

I have been running an arcade website for quite a while now, and have run into something strange.

Recently, my pageviews according to adsense have skyrocketted. I mean, from hundreds in a normal day to many thousands in a normal day. I would nornally think this is great, but I am still getting approximately the same number of clicks per day. I am sure there is something that this means, but I don't know what it is.. Anyone? Not much else has changed on the site since this started. I certinally appreciate any help. Thanks

 

Where is all the traffic coming from? It may be a low-converting source.

 

I also noticing its going down.

 

Perhaps try different add placements.. different color schemes.. change it up.. spice it up..

 

Did you happen to submit your sites to social bookmarks and that's where all the traffic is coming from? If it is, it could be the reason that got your CTR to go down as the traffic is most of the time not converting.
