I was seeing the Google Analytics for one of of my website.
There was a abnormal increase of traffic from 15th May,2015. Further testing revealed that abnormal traffic is coming from Organic visits with a new set of keywords (new set of keywords are mainly used for porn site searches).
The landing page urls for the keywords are also abnormal like following:
which are returning to 404 page error as no urls like the above are there.
The website is for reality dealers.
Website : Acredeals.com
What are the measures I can take to overcome this type of problems?
Please suggest ASAP.
