Oftentimes my site has content which I'm not really interested in having included in search engine results. Examples might be a "view cart" or "checkout" page, or old products in the catalog that are no longer available in our system.
In the past, I'd blocked those pages from being indexed by using robots.txt or nofollowed links. However, it seems like there is potential link juice that's being lost by removing these from search engine indexes.
What if, instead of keeping these pages out of the index completely, I use to reference the home page (http://www.mydomain.com) of the business? That way, even if the pages I don't care about accumulate a few links around the Internet, I'll be capturing the link juice behind the scenes without impacting the customer experience as they browse our site.
Is there any downside of doing this, or am I missing any potential reasons why this wouldn't work as expected?
