My website is 6 years old and for 6 years I get on average 30,000 unique visitors per month and 2 - 3 Million hits per month. Well all of a sudden in May - my stats DROPPED to 1000 unique visitors and 55,000 hits per month!! As you can see this is a HUGE drop! I did not understand why as I'm still at the top of google. Well today - I noticed in my Admin panel where my customer register - I noticed nearly 100 fake Profile registrations with KEYWORDS in the address section. This started ironically on April 28!! It just seems like too much of a coincidence. What type of company or person would I hire to investigate this?
