This whole traffic up one day and then down the next day (when you have the same SERPs) is really getting to be annoying. But I do notice that this only happens to certain set of sites not all of them. Some sites are the same about everyday without any spikes either up or down. I wonder if we can attribute this to G showing SERPs from a different DC to majority of the people and on those DCs the sites aren't ranking as high.
