I have a client that want a website with a single domain name with many different extensions like:
example.com example.org example.net example.mobi example.tv ...
Just to be sure the saturate the name and that nobody "hijacks" the name.
The client is a searcher in "numeric content" and has a PhD in that field of expertise.
I think it would be overkill to go that road since the website will only attract a limited amount of people which will be referred mostly through official press documents and business cards with the web URL on it. Since he is a scholar I was looking for some published articles about that matters.
I'm looking for published articles about why it is good or bad to have multiple domains for a single site.
P.S. In the end if he is still convinced that his way is the right way I will do it, but since it comes from a public-funded grant I was looking to save him money (and the general population) so he can use the rest on more useful areas
P.P.S. I am from Québec, the most taxed state in North America, that is why I have those concerns.
