Might Google assign a keyword to an entire site?

This may be obvious to other people, but I've only recently begun thinking about it.

Anyway, I have an old site about preserving rare widgets, with about 25 pages, most of them focused on one particular type of widget. There is no single page just about the general subject of widgets, but because of the nature of the site, the word "widget" probably appears at least once on every page.

What I've noticed is that the site gets a lot of traffic from Google for various long-tail searches containing the word "widget", even though in many cases the content on the page isn't a good match to the search phrase.

This has given me the idea that in Google's eyes the word "widget" is a "sitewide keyword" for my site.

I know that keywords are usually thought of as pertaining to a single page. But in this case I think that Google has assigned a keyword to the entire site. Does this make sense?

Thank you

Google finds keywords. If your widget is fairly unique, and appears on each page, you might be showing up very consistently, thus appearing to have a single keyword for the site. I doubt that is the case.
