Hello, For at least one month, our website is getting fake traffic from the main keyword where we are on the first page on Google. I have never seen such attack to us before and this is new for us. We believe some people making anti SEO and this is how they are doing. Fake traffic from the main keyword on the first page. They are not doing this every day but at least a few days in a week and the average time on website is fairly low. I believe this fake traffic with a very low average time from the first page position keyword makes us lose our position? What do you think? And do you know how to prevent this or how to take precautions? Should we report this to Google from GWT panel? Thanks.
