I have a few websites, where one is the name site and the rest are just for building links. What I have done is that I have created many category pages on the primary website. However, I have also used another domain name for one category page. Will this affect my ranking? I also want to know if this will give result than the regular linking practice. I am just praying that it doesn’t come with a negative impact. Has anyone done the same practice? Did it prove to be fruitful? If it had a negative effect, what did you do?
