Question About SEO
 

A business colleague of mine has three businesses which are in the same line of venture and category. He would like to efficiently increase his business deals with his three businesses and expand other three niches. He is well adaptable with maintaining three arenas and which have a professional, functional and exclusive homepages. This could leave three categories which could command all his three online domains. I have recognized that this is not compliant with the indexing rules and standards of Google. Thus, the sites have a great possibility of being unrecognized and worse; it could not be indexed in Google�s search results. Do you have any input about this? Any opinions are highly appreciated.
