When someone is doing affiliate marketing link, he must use rel=“nofollow” on every paid link.
Right now, we can add rel=“nofollow” only in html block and not in the link used in text. That’s a limitation for affiliate marketer who want to link to complementary product directly in the text. We are unable to do so and we cannot risk the Google / Amazon penalty to not use rel=“nofollow” on paid link.
It would be nice to have more flexibility over the html generated by our post. We could click to a link like “edit as html” or something like it and manually insert rel=“nofollow” inside the affiliate links. Another option would be to have a cog opening more tag option when we do a link directly in the text.
Reference from Google : Use rel=“nofollow” for specific links
Paid links : A site’s ranking in Google search results is partly based on analysis of those sites that link to it. In order to prevent paid links from influencing search results and negatively impacting users, we urge webmasters use
nofollow on such links. Search engine guidelines require machine-readable disclosure of paid links in the same way that consumers online and offline appreciate disclosure of paid relationships (for example, a full-page newspaper ad may be headed by the word “Advertisement”).
