Hello,
Cross Linking- a strategy that can come in handy to get high search engine rankings, by leveraging multiple domains owned by you. Search engines value these links, as they are from relevant sites, with related content- and you stand a chance of getting a better rank.
The most common practiced strategies for cross linking are- footer/sidebar links and in-content deep linking. If you have links to your page (containing your keywords) from other domain names, then this really works well with the search engines. This means that the key here is to cross linking these sites, with related and relevant content and using keywords . This will get you a higher rank for the keywords in question, and will benefit all your domains.
