I currently maintain both a retail store and a repository of user manuals for those products. These websites are both situated on the same domain (mystore.com and manuals.mystore.com respectively).At present, on many individual manuals, I have added a Buy From Mystore.com button, linking to the appropriate page on the retail store. In addition to these links, I'd also like to add a small banner on some categories (say Accessories) linking to the appropriate section of the retail store in a similar vain.I was just wondering if it is recommended to use nofollow on these links, or whether I am safe to exclude this as they are not necessarily pay links and link to relevant content of our own.Thanks for reading. I apologize if any info is needed, I am happy to elaborate if needed.
Should I use nofollow when cross-linking between two sites I own on a single domain?
