Code Blocks and SEO

Site URL: https://shelfielife.com/shelfielife/lore-review

Hello - I am hoping someone can help me with this one!

As part of my blog I include book reviews from Goodreads, I simply take the code and put it into a code block. Is this ruining my SEO ie: does Google, etc. pick up on the content in that code block?

I inspected the page and the source IS going back to Goodreads (which I do not want, so I am trying to see if I can change the code to redirect back to my page). I will not attempt to fix the code if it does impact my SEO.

I hope that made sense! Thank you in advance!
