The obvious repercussion you could run into (and rightly, I would add) is Safe Search. For that reason, you might want to put any borderline adult materials into their own directory and make it easier for search engines to isolate what to filter.

No guarantees that will work, of course, but it would be a start.

Can you please clarify when you state "add... Safe Search", is this submitting the product URLs to Google or another online service indicating to them the content is not safe for kids?

Google has their own Safe Search algorithm - the default for it is "moderate", but "strict" and "off" are user selectable. See this page: [google.com...]

Your website's text and/or images can trigger that filter and then you don't show up in the search results except for users who have turned Safe Search off in the Search Settings - which can be accessed by clicking the small blue gear icon at the top right.

Ouch, that would be pretty rough. Thanks again. I am going to look into this before adding those items. I am mostly curious to know if it's a whole domain block or a block on a per page basis.

Ir's not always clear how it works. Google tends to err on the side of being overly cautious - especially in Image Search, but their caution is not restricted to Image Search. There's a lot more problem from letting little ones access adult content than from a few false positives.
