There has been an unusual raise in my website page views. During the day I usually get 40-50 page views per minute, but its a few days now that i'm getting about 150 page views/ minute, and there is no significant change in visitor count.
The first time that I saw that, I thought it might be a bot, like Googlebot. I don't think Google but likes me so much that it won't leave my site.
What can cause this? Can it indicate a problem?
My website is a free website offering baby names with their meaning. There is nothing special to hack.
EDIT: the new thing in a few days is that I have got a company place ads in mywebsite and each ad loads in an iframe. can it be cause it? does google analytics count iframes too? the content of iframes are some ads from that company and absolutely has no analytics script.
