I just pulled a search on Google for a keyword in one of the top notoriously difficult niches to rank in. Right on the first page at position #8 this guy is ranking with 1,082 links from his blog network. If I had a network this big I feel like I'd have to be literally insane to leave it wide open for majestic, ahrefs, moz, and my competitors to look it over. I mean any "white hatter" in his niche could uncover this and send in a report on him. Assuming that all those blogs were hand registered, (though I'm sure some come from auction) let's estimate for $10 each plus free private reg... we're talking $10,820 minimum, plus thousands upon thousands of hours down the drain if just one of his competitors reports him for a manual. After plugging in his backlink metrics here is some interesting facts for you guys, aka a blueprint for his competitors on exactly how to rank. He's basically going straight in the face of common "SEO knowledge" post-Penguin when it comes to anchor text and is probably banking hard even at number 8. - All links were built starting in early March that's over 1k PBN links in a month or two - Only 9 of these backlinks are Nofollow - All short-tail KW, not one is longer than two words - 23% exact match anchor text for his primary keyword - Less than 1% Naked Anchors - Less than 1% Generic Anchors - 13 different anchors total - 0 Branded Anchors Then to top it all off we have a 301 redirected domain pointed at the site. The redirected domain has nearly 200,000 (Ahrefs metrics) pure spam links courtesy of GSA SER/Xrumer Lastly, the WWW subdomain turns up 25 links in total mostly business directory links and 0 redirects or PBN links. Let this be some food for thought for you guys. He's lucky I'm not Matt Cutts, or a white-hat butt-hurt competitor he'd be in deep crap. Actually I sort of admire the guy. I've never seen such a Herculean effort like that perfectly documented clear as day courtesy of AHrefs. Just a word of advice guys if you're going to point hundreds of PBN links at your site, at least try to hide it from your competitors. No I won't reveal the niche, let's just let the dude rank in peace.
