I've had a website up and running for about five years. It's a content website, I followed all best white-hat practices for on-page SEO optimisation, the site seemed to naturally got back links, ranks well in Google, and gets over a million visitors a year (nothing major but it's a nice side hobby).
The site is related to an 'academic' area and I am thinking of adding some amazon affiliate links to the books that are used as original sources for the content on the website.
The thing is I don't want to add the affiliate links to the content pages themselves and instead wanted to add a whole new section to the website, sort of a like a book catalogue section with reviews of each book which would include the affiliate link.
To give a related example, if you think of my website as being like Smashing Magazine and in the same way they have "Books" as a section of their website, I want to do the same but the books will be linked to amazon (obviously in the correct way e.g. clearly stated as affiliate links, no followed links etc.).
I only want to do what is OK in terms of Google algorithms so my query is around whether adding a whole section to a website like this would be viewed negatively from a Google algorithm point of view and get my website a penalty?
