So some people mentioned my site on Facebook then all of a sudden I had a surge of traffic, Facebook Fan page jumped up by 35 users (alot for me), I had 2,000 pageviews very quckly, 8-9 pageviews average per person, average time is 8 minutes and growing, bounce rate is 20-23%. Traditionally (the last 2 weeks) I have been getting similar numbers, but I never had the spike in traffic so quickly. My CTR is very low less than half a percent, which I am trying to optimize (suggestions would be GREAT). So what I am wondering is the retention rate of the users. Will they come back again tomorrow?
