I think that this person brings up a good point, which I have never seen answered in any posts that I have seen about this, in any forum that I have read.

I sell domain names (among other things) + host accounts and I always recommend to my clients purchasing several domain names. For instance, if the company name is Ben Johnson company, I recommend benjohnsoncompany.com, for those looking for a website based upon the company name.

Next, if they are in the diaper cleaning business, I recommend getting a name such as cleandiapers.com, to indicate what they do for advertising purposes.

Next, for e-mail purposes, I recommend a very short domain name, such as bjc.com, so people can e-mail ben@bjc.com, instead of ben@benjohnsoncompany.com (saves typing a long e-mail address).

Finally (and not so much anymore), I recommend a search engine name, such as clean-diapers-dallas.com for keyword presence in the search engines.

Now, since they have all of those domain names, I will park them all on their hosting account so that if someone types in any name, it will go to their website home page (makes sense).

So, as far as the search engines are concerned, wouldn't they just index the first domain they see, then disregard all of the rest, such as when an article is on numerous websites?

I also see, an example of a 25 page website that maybe 5 pages are indexed under 1 domain name, another 5 pages under another, and so on.

This is a common situation for I'm sure a lot more people than you would think, they just aren't posting about it. Is it so wrong to do this?
