3 days before Easter, my earning going down 70% it make me little panic, but i think everybody have a family time and going to church or vacation but after Easter the earning going up for triple. so for everyone, if your earning getting low in holiday dont be panic, because it just happen in holiday after holiday it will be normal I'm very happy and Happy Easter thank you Lord
People don't go online much over Easter. Myself, I go away every Easter (need to put a stop to that and get the relatives to visit me). And came back to see quite low traffic and earnings over the weekend. Its actually a 5 day long weekend in Australia because ANZAC day coincides with Easter.
For me also earnings went down during the holiday time. And, I have noticed that earnings got reduced very low even if the clicks are reduced in moderate level only. i-e CPC is reduced So, I think many high paying AdWords advertisers might have suspended the ads during the holiday time.
I think it is natural, and common to almost every holiday. It also depends on your niche. Some websites just living from holidays and this is the period when they only making money.
