Question about Wordpress header styles

Hey everyone,

I'm wanting to build several blogs pointing to my main sales page.

My question is the style of blogs that I'm going to use and also the use of pen names.

My main site is a wordpress static page not allowing comments, but the blogs out there that are pointing to the main site should they be normal blogs allowing comments?

Also I'm wondering about my web presents, do I want to have several blogs that all look the same as if obvious they are all from the same person and have some consistency with the sales page or should they all look different making it look like there are several different people sending their traffic to my sales page?

So, do I want researchers to think that I've got a bunch of sites all telling them to go to my sales page or is it better for these searchers to find and think that many different sites are all sending them to the same place.

Now that I wrote that out it would seem to me that having several different looking blogs and different pen names all pointing to the same place would give my sales page more credibility.

What do you think??

Thanks for your time!
