We definitely do NOT dismiss it!!! It just means you need to spend a lot more time finding the real reason, or maybe you are getting traffic from the wrong group of people who have no interest in your product anyway.

Good example would be Product Hunt or Techcrunch as a traffic source, mostly useless for any testing as everyone on those sites is just interested in 'new products' or startups and is unlikely to be in your target demo.
