Linking Between Domains

[theLotter]

My company has a main xxx.com website and geo-specific subsites - xxx.co.uk, xxx.es, etc...

We link to each of the subsites from the menu, however it also makes sense from a content perspective to link between the sites on internal pages.  However, in this video Matt Cutts seems to discourage this - http://searchengineland.com/googles-matt-cutts-linking-20-domains-together-likely-a-cross-linking-scheme-167089

Do you think its worthwhile to keep the inter-site linking to just the menu or okay (or even helpful) to link between the different sites.

I don't understand exactly what you are asking?  Are you asking us to disagree with Matt?  Or is your question more specific?

[theLotter]

I would never ask someone to disagree with Matt!

I was more asking based on Matt's video if linking between sites should be discouraged even if it would be beneficial to users or if it should be avoided because has negative SEO ramifications.

I don't hesitate to link between one of my sites and another when the site that is being linked to has strong content that will provide further information of interest to the reader. I don't have a lot of these links. Just a few. I could count them on my fingers. I would hesitate to place footer links, blogroll links or other copious amounts of links between my own site. Those are not offering specific guidance to the visitor. I also have an information site where I run banner ads that click to a retail site that I own. These banner ads compete with Adsense on the basis of value using the DFP ad server. If you have any concerns about the links between your sites you can always add "nofollow".
