Thanks Andy, and your explanation seems good, for the following reason. A few days after updating the page in question I was looking at my site stat's at my web-site host and I noted that "Google.bot" had been at my site a couple of days earlier.
My site is an odd-ball site from the viewpoint of SEO principles (as I understand them); because the common key words/phrases in my business would never get my site listed on the first 30 pages of a search engine's output. (There are many thousands of vendors with products for which those more common key words are appropriate -- many are big-name financial services firms and many already have a ton of traffic to entice the Google.bot to revisit them soon.)
On checking at the Google Adwords tool while updating my site I found that phrases which point much better to my content are in **very** low usage around the world -- which means there is no traffic out there to be driven to my site by simply doing my SEO very well (exaggerating a bit). That ties in with your explanation.
Thanks again; because your reply means that my SEO strategy has to go beyond trying to optimize for Google, given my special business, I think.
