How to avoid adult traffic to site?

[MediaCause]

A client of ours is increasingly getting a lot of adult traffic to their site, where they show up only for adult searches and not at all for relevant searches. How can we stop Google associating their site with adult content?

Here's a blog example, giving advice to parents on girls and body image issues:

https://www.commonsensemedia.org/blog/girls-and-body-image

keywords driving traffic to this page are all around images for 'young nude girls' etc.

Have you tried to look through this article https://support.google.com/websearch/troubleshooter/3111061?hl=en or search through Google Help secitons?

Yes, for different pages with older content we have recommended to hide them from Google. This specific page, however, could is highly relevant to their audience and we want their audience to be able to find it so we don't just want to hide it. We have looked for solutions on the help forum but haven't found anything relevant to this issue.

Does anyone know if there is a way to tell Google that our website is safe to avoid this problem in general?

Or is it just a matter of finding other relevant keywords and synonyms that are currently not being used to see if that will help Google better understand the topic of this page?

Or could there be another problem that we're missing?
