I have 20+ domains in the same niche, all with different content. They are all Wordpress sites. What is the difference between addon domains and 301 redirects from a SE standpoint? Would it be better to: A) Create an addon domain in CPanel and point it to root? Then dynamically serve up the unique content based on the domain (using a plugin)? B) Use Wordpress Multisite with domain mapping? I believe this uses 301 redirects. Thanks for your input, have been racking my brain on this one.
