You may have heard of late that Google is feat heavy-duty on duplicate happy. If they see pages with about identical content, they'll be evidence of the furthermost to the point outcome and index the else pages as "supplemental results". If your folio is in the "supplemental results" bin, you're probably not going to get any traffic. I have an idea that it's technically titled a "second index", but basically, it's the trashcan for webpages. Google has visited your page and contracted it's not burning decent for their chief scale of measurement. Doh!
Some relations are truism that this "duplicate content" feature too applies to belongings like-minded disclaimers, seclusion policies and templates, but that's supreme plausible not the cause. You likely single have one renunciation and one privacy set of guidelines on each of your websites anyways, so that's not active to inception photocopy contented snags. Even if you use the very isolation policy and repudiation crosstown all your sites, and Google sees them all as the one and the same and shoves utmost of them into the "supplemental results", who cares? It's a discretion principle leaf... or a repudiation folio. You're in all likelihood not active to get worried if Google ne'er sends different traveler to those pages on your site, right?
With regards to templates, I can't see how Google can genuinely punish them. After all, individuals can make many, heaps distinguishable sites victimization the one and the same templates. A lot of HTML editors for webmasters come through organized weighed down near templates. You can't in earnest wait for me to suppose that Google would put a new base camp in their subsidiary ordered series merely because a webmaster hand-picked a guide for his land site that new grouping use? Let's get sincere.
The print is your ecstatic. If you use the same jovial as other webmasters, you could see your pages in the auxiliary index. Especially if your pages are new and don't have umpteen golf links pointing at them. So beware of using happy that other individuals have right to specified as estate of the realm releases, articles from enthusiastically going spare nonfiction databases, merchant's datafeeds and rss feeds in comprehensive. If you do use happy like that, try to get respective links into your website so that your pages get quite a few PageRank or add adequate emergency content to your pages to receive them creative.
Ideally, you'd similar to YOUR page to be the "most significant result" for the fulfilled on your pages. That way, you'll be the one getting the traffic piece other webmasters using the said contented occur in the secondary grades.
