I have been worried for more than 2 weeks now because my site traffic drops 70% since the start of google dance and I was thinking if my site was penalized or I must have done something wrong.. But today I was so happy to see that my site is back on SERP and traffic now are coming back to what I have used to have before.. I feel relief and take a rest for several days and wait for money to come in again
Easter, kids off school, even what is on TV, what the weather is like, etc can all affect traffic depending on your content.... it's not just google. All goes to show that you need to give things at least a couple of weeks before you panic Glad your traffic has started to climb again.
Good to hear that, Search Engine always update their systems and every one get his down-times. Best of luck
Maybe your server was down when google came to crawl, and they finally returned again. I'm assuming thats a possible issue were they think your sites gone.
