Siloing, Dilution and Why Can't I Link to My Own Sites?

I am in the process of redesigning one of my websites from the ground up with SEO as the primary focus. I have one main site with several smaller sites that provide a variety of closely related services in the same industry. Originally, I had intended to gather all of these services onto my main site, which receives thirty times as much traffic as all the other sites put together, and include them as part of the new development of this site.

However, I have been doing some research on "siloing" and I have discovered that, from an SEO standpoint, it is better to keep the services I provide on separate domains even though they are in the same industry and all very closely related. The argument goes that if I provide all of these services on one site it will dilute the "authority" (in the sense of "focus") of the site.
To give you a completely imaginary example, let's say I own,, and Although they are closely related, they are definitely separate services that could survive and flourish on their own they are also all part of the "stew-making industry". has grown to become a big player in its service field and I want to incorporate all of these services on my site.

The questions is: Is it better to keep them separate on their own specifically related domain name with the exact service they provide included in the domain name? Or is it better to take advantage of the traffic at the well established domain name while taking the chance that it might lower my ranking all across the board because it dilutes the overall theme or "silo"?

Also, if I do keep them on their separate keyword related domains, can I link them from my main business of Will Google penalize me for linking my sites together? I don't quite see why they would do that when I have never hidden the fact that these are all my sites and that they are directly connected. In fact, I advertise them that way. However, others have said I should be careful about linking my own sites together. Why? What is Google's reasoning here? Why would Google, in effect, put limits on the number and type of businesses I own?

Any and all input -- whether its scoffing, debunking or clarification -- is appreciated.

    This is a pure case of "make a test"

    What I'm saying is that if you want the best response then provide for a period all your services on your main website and see how the income react...

    If one service do not exclude the others then I will suggest to link your website between them. If a person come to your main website can he, or there is a possibility that he would by all your service?

    Now there is another question that as an economist I must ask it... witch is you most profitable service?... I ask you this because if you have a service that bring you 10$ on a 1000 visitors website and another one that bring you 5$ on a 2000 assuming that all the visitors will buy your service then it will be more profitable to move the 10$ service on the 2000k website since in the current situation both website and services bring you the same profit... I thing you got what I want to say.

    In terms of SEO there is no problem to link the website between.

    And to see what is the best configuration I would go for a test and run it for a few month.
