    I was looking back through a large number of my PBN domains in majestic and I noticed that most of the numbers that I originally based my domain buying decision on had changed drastically. Referring domain numbers had increased from 20-50 to in the hundreds/thousands for many of my domains, as well as trust flow/citation flow altering, sometimes positively sometimes dropping drastically. While I don't record the TF/CF numbers when I buy a domain, many have altered so significantly that I would never have even bothered investigating the domain in the first place.

    Fortunately I analyse anchor text and check for any drastic changes in appearance of the site to eliminate spam/previous PBN sites but the referring domain numbers have increased so dramatically on many of my sites that I would have ruled them out as spammed initially.

    Now before the 'don't trust metrics' crowd get on board, metrics are simply part of how I whittle down potential domains. I churn through hundreds of thousands of domains a week and they're useful for finding a level of quality that I then investigate further.

    Has anyone else noticed this and what do you make of it?

    No definitely not, I only work with the root domain.

    The reason for the fluctuation when you type 'www.' before the root domain is because you're viewing only the backlinks to that sub-domain which don't make up the full picture. In essence the subdomain metrics are usually (but not always) higher because dilution occurs for the root domain.

    Gosh, you see less link for http:// is because it is exact links to that SPECIFIC URL. Of course http:// pornhub.com has less links since root domain of pornhub.com contains http:// pornhub.com + http:// pornhub.com/hardcore + http:// pornhub.com/chickenporn + etc.

    It is not perfect, but far away from flawed.

    I commented on massive fluctuations in Majestica data about 3 weeks ago, too.

    If it can range so wildly in a short period, one wonders how credible it could ever have been...

    I do recall seeing it now you mention it, it's the referring domains that bothers me the most. This is an unscientific attitude to take but my approach still ranks websites and ranks them well, so if it's not broke (the approach - not Majestic)...

    Is ahrefs showing same fluctuations or is this just majestic discovering old links?

    Sorry I don't have that information, I give only a cursory glance to ahrefs for the purposes of anchor text only after a site has made it through my vetting process. Some domains do demonstrate a drop off of links around the time of re-registration though according to ahrefs.

    No way!

    But this quote is particularly worrying: "Referring domain numbers had increased from 20-50 to in the hundreds/thousands for many of my domains"

    Someone is definitely spamming those domains dude. Did you properly block backlink bots?

    As per my comment that you dismissed, it's a dilution effect. If an average wasn't being calculated somewhere then TF/CF would increase exponentially well past 100 (obviously impossible) as more links were added.

    I have indeed blocked bots but I wont rule out spamming just yet, although I see it as unlikely. On domains where no referring domain inflation has occurred, I still see metrics swinging either way like a confused teenager...

    Honestly, I don't see any possibility other than spam that explains the ref. domains count jumping from 20 to 1000's. Unless your PBN got viral there is just no other explanation.

    Why not check the backlink to see wether there are any GSA SER or Xrumer links in there? They're very easy to spot.

    This is why I frankly don't trust the data from any of these services. Google doesn't provide accurate backlink data, and the third party services all provide entirely different numbers for a given domain or URL. OpenLinkProfiler will give you entirely different backlink totals than Majestic or Hrefs. Even Majestic and Hrefs often don't come close either. To make matters more confusing, some spammers will block the spiders from these services, so they cannot accurately scan their sites and find all the backlinks and other data on the site in the first place. In fact, in many cases I've manually tried to visit the pages these backlink reports were listing, and could not find a backlink on many of those pages at all, even when going through the source code.
