Welcome to the Q&A Forum

Hi, I'm at a bit of a loss. For the last few days our web site has been visited by a significant amount of what looks like spam visits. The visits are to a single page, have location as "not set" and all have a bounce rate of 100%. This activity observed on Google Analytics. I see similar behaviour for an additional approx. half of the "not set" visitors in number from San Francisco i.e. to a single page etc. I see no unusual activity on the actual web site like spam blog comments for instance, but I'm still concerned. Any idea what this can be and what I can do about it. The net impact of this is to raise the overall bounce rate of the web site to > 80% when it usually runs around 50%, so these visits are significant in number for us. Help appreciated. Charles
