[REQ METHOD]How to investigate why my website visitors number has colapse?

Hi folks.

My website visitors are at least 75% down. In August of last year my website suffered a catastrophic loss of visitor numbers. It also went from a very low bounce rate to a very high rate. Could be a Panda problem, or a content quality problem? Also, could it be some deliberate malicious act by a third party?
How can I verify, and solve it?
Sape links can get me out of this problem?

Thank you very much

Ricky,

Its hard to say whats happening without more data. Did you make any changes to the site? Did you make any changes or launch any initiatives off the site that could have directly affected it? I would think real hard about anything that you could have done and focus your attention there. Also, comb through your analytics data to pinpoint a date when things started and what may have happened on that day.

Do an audit using a third party program. Look for links built by someone else.

Best,

Shawn
