Home Drug Testing Kits, Pregnancy Test Kits - in only a few minutes i found several spammy sitemap pages like this.

this is a big problem and google will have issues determining what is what, if not deciding that it's seeing duplicate content in some way shape or form.

additionally you're serving up two different homepages:

1. Drug Tests & Urine Drug Testing Kits & HIV Home Tests & Tests for AIDS at Test Country
2. Home Testing Kits & Home Hair Drug Test Kits or Urine Drug Testing San Diego

Question: When was the redesign launched? If so, did any of your previous URL's change in the process?

Quick Advice:

1. choose either non-www or www and 301 permanent one of them to the other. my advice is to take a look at what address the majority of people are linking back to you and then decide...are they linking back to your domain with the www or non-www.
2. do not 'over optimize' the website.
3. avoid duplicate content
4. do not write copywriting simply for the bots
5. evaluate the value of existing content on product pages. is there any?

Always remind yourself that Google has over 200 key algorithmic differentiators that separate it from is competitors. If you feel any doubt about something being wrong....it probably is. Don't optimize for the bot. Instead, using SEO best practices, make sure the users experience is a great one and they will come back and share it with their friends.

this is about all i can answer with having only 5 minutes to write
