You may have detected lately that Google is acquiring chewy on same glad. If they see pages near nearly very same content, they'll provide evidence the supreme at issue outcome and register the otherwise pages as "supplemental results". If your leaf is in the "supplemental results" bin, you're in all probability not going to get any aggregation. I devise it's technically named a "second index", but basically, it's the trashcan for webpages. Google has visited your page and decided it's not serious plenty for their leading scale. Doh!
Some folks are adage that this "duplicate content" cause besides applies to material possession same disclaimers, seclusion policies and templates, but that's record possible not the causa. You belike lone have one disclaimer and one shelter argumentation on all of your websites anyways, so that's not active to result in duplicate in high spirits technical hitches. Even if you use the identical isolation policy and disclaimer crosstown all your sites, and Google sees them all as the same and shoves utmost of them into the "supplemental results", who cares? It's a discretion logical argument folio... or a renunciation folio. You're likely not going to get distressed if Google ne'er sends other visitor to those pages on your site, right?
