How do I set up 2 businesses that work together but are ran seperately with two separate websites but similar content?

How do I set up these sites so that they will not be negatively affecting their SEO efforts? I have 2 businesses with the  same owner. Business A manufactures nurse call systems and Business B installs them. They are run separately with two websites. The content is very similar because the business that installs them describes the different products on their website. These are the two sites: intercallsystems.com and nursecallny.com , My thought was on nursecallny.com when you click on the nav link "Nurse Call Systems" you would be directed to the intercell website. Would this be the best method? Thank you for your  help!

It is definitely possible to maintain two separate websites. It sounds as if they don't do the same thing, so technically the content will be different. The websites use a different template, and from what I can tell they don't have any duplicate content issues.

Since the sites are related, it would be natural for the two websites to link to each other. But you don't want to run into any search engine penalties from having them link to each other. In order to do that, you'll need to make sure that the link profiles of each website are completely different.

What I would focus on is the links to each website, and have a plan to acquire good, trusted links to each of them. One is product related, so you'll want to focus on where you can get your products listed. The other is a service type business, so getting the site links that are appropriate for that site would be helpful.
