Hide portfolio pages from showing in search results?

Hello! 

Due to how I wanted my website to work, I have my home page set as one of Squarespace's "Portfolio" pages. Issue is, I'm not a fan of particular portfolio projects showing up in search results. Screenshot attached as example. 

However, in the SEO settings of each portfolio project it is not giving me an option to hide from search engines. Screenshot attached of what I see in that menu. Any advice?

Thank you!

Hi Mike,

The best way to do this is inject a "no index" tag into the pages you don't want to be indexed.

You can do this following the below guide:

Feel free to reach out if you have any questions.

Thanks for you reply! I've tried the code injection, we'll see if it updates over the next week or two.... but as you can see from the link you sent, it sounds like this method won't work for portfolio sub-pages?
