I've read through several pages at the Google site including the one referenced in the email below, but am none the wiser here. I've also asked several other webmasters to take a look and they too are a bit mystified so any guidance you can give would be appreciated.
Thanks in advance.
Here's the text of their email.....
> While reviewing your account, we noticed that you are currently

> Publishers may not place Google ads on pages that violate
> Google's webmaster quality guidelines
> 769#quality). While we've included the following excerpts from

> them in their entirety.
> * Make pages for users, not for search engines.
> * Don't employ cloaking or sneaky redirects.
> * Don't load pages with irrelevant words.
> * Don't create multiple pages, subdomains, or domains with
> substantially duplicate content.
> * Don't participate in link schemes designed to increase
> your site's ranking or PageRank.
> * Avoid "doorway" pages created just for search engines, or
> other "cookie cutter" approaches such as affiliate programs with
> little or no original content.
> * Avoid tricks intended to improve search engine rankings. A
> good rule of thumb is whether you'd feel comfortable explaining
> what you've done to a website that competes with you. Another
> useful test is to ask, "Does this help my users? Would I do this
> if search engines didn't exist?"
> * If your site participates in an affiliate program, make
> sure that your site adds value. Provide unique and relevant
> content that gives users a reason to visit your site first.
> As a result, we have disabled ad serving to the site.
> Your AdSense account remains active. However, we strongly suggest
> that you take the time to review our program policies
> (https://www.google.com/adsense/policies ) to ensure that all of
> your remaining pages are in compliance.
> Please note that we may disable your account if further
