Today's goofy question

:: insert boilerplate about how I'm not sure which of 4 forums was the right place to ask this one ::

Are there legitimate and law-abiding ways to "break" your own search results on purpose?

Real-life example (I have a few similar ones): I am darn sure that the people whose googlings lead them to Grandmother Puss, or the Grateful Mouse are not looking for an obscure little picture book dating from circa 1870. I would prefer not to contemplate what they are looking for. It is not a problem in any concrete sense (like bandwidth loss), but everyone would be happier if these particular visitors didn't waste time here in the first place.*

I am thinking something like a global replace of the undesirable words with

pu<span class = "invisible">cat</span>ssy

or

co<span class = "invisible">rooster</span>ck

accompanied of course with appropriate CSS.

Would this work? Obviously not with search engines that use the surface-level text, but will it fool the ones that work from the raw html? Would search engines get mad at me for doing something intended to reduce search results and visits?


* I have occasionally added content to pages when logs suggest that visitors are looking for information that isn't currently on the page. No skin off my nose, and it builds goodwill. But, well, there are limits to helpfulness.
