Hello, I have a question. Let's say I have a link from domain mydomain.ccc/a.html to myseconddomain.ccc/b.html and a link from myseconddomain.ccc/c.html to mydomain.ccc/a.html Are these considered reciprocal links?
Not they are not. Reciprocal links involves links exchange agreement between two sites while the example you mentioned above is actually a 3 way link exchanges.
I think this would still count as a reciprocal link because it is only 2 domains. Think about why google values non-reciprocal links - they indicate an authority site as opposed to a link exchange. Links between sites on different pages will still look like an exchange rather then one of the sites being an authority.
