How are our competitors getting these inbound linking domains?
-
I'm currently managing SEO for my company's website, and I'm getting into link building for the first time. As part of the process, I'm using Open Site Explorer to see who's linking into our competitor sites, to get a better sense of what's available to us in our particular avenue of e-commerce. However, I'm finding that our competitors are getting inbound links from high-authority sites pretty far afield from selling jewelry - census.gov, parallels.com, warnerbros.com, and others. I try clicking through to these links, but each link starts a download of a file. I've seen .f4v, .7z, and .apk files listed as inbound links to our competitor. How is this happening? Again, I'm new to link building, so there may be a simple answer here, and if so I apologize for asking. However, this seems really strange to me, and a difficult situation to confront.

Hey guys,
Yep, Keri is correct, unfortunately
We found a bug in ourJuly index with our new crawlers - they were crawling binary files as if they were links and, since they are not normal links, the crawler couldn't handle them very well.
We have made some updates to our crawling so it will go deeper into sites. The reason for these odd inbound links from high-authority sites is due to the crawler reaching much deeper into sites where there are more download (i.e. binary) links. The first issue is the crawler is counting a binary file as a link, but the larger issue, is that the crawler doesn’t really know how to handle these types of files. This bug is causing some links to be improperly associated with certain domains. This is why you’re seeing inbound links to pages that don’t really exist.
There are two steps to addressing this issue: changing how the crawler sees these file types and then fixing how the crawler handles these file types. We have made improvements to our algorithm so that we will be able to handle the majority of these files correctly, however, this update will need a few more weeks to propagate. The fix for this issue probably won’t be seen for another update, meaning late September. Our improvements should catch most of the issues, but there still could be a few cases we haven't addressed. If this happens, don't hesitate to let us know; we love feedback since it helps us improve and make our index even better!
The next step is to fix how our crawlers handle binary file links and prevent them from being improperly associated with certain domains. We are in the process of working through that issue right now. We’re doing everything we can to resolve this bug as we know it is alarming to see these phantom inbound links.Thanks for your patience!Carin

I think you might be seeing a bug in the way OSE is treating binary files as having links, starting with the July update. See this thread http://www.seomoz.org/q/latest-ose-update-strange-numbers-and-links while I ask for Carin to step in and comment on this question.

Here is a good list of them from Parallels.com. The Page strength is only a 17, but the domain strength is 100 and the links are not nofollowed.

Here are a few I've found (beware, I don't trust these links really):

I'm glad you posted this, because I noticed the same thing with one of my competitors as well. It was a file from Parallels.org, and I couldn't for the life of me figure out what it was. Anybody got an answer?

I have 2 linking root domains on my URL. But I don't get the whole Root domain thing. So I don't understand how I can improve it?
I have 2 linking root domains on my URL. But I don't get the whole Root domain thing. So I don't understand how I can improve it? I copy and pasted this, from my Links page in my campaign because I can't seem to grasp what a root domain is: 'A higher number of good quality linking root domains improves a page's ranking potential'. Can some one explain to me what this is. As simply as possible. Here's my site www.Thumannagency.com Thanks in advance:)

Sitewide links causing problem
Hello, I've had a couple of people look at the backlink profile for nlpca(dot)com and tell me that there were a lot of sitewide links with non-branded anchor text. The spreadsheet is [here](http://thewealthymind.com/wp-content/uploads/2013/03/anchor-text.xls). Actually, because of our company name, all sitewide links have branded anchor text except for http://www.iepdoc.nl

http://www.ionut-ciurea.com The term "NLP" is not ranking for us, we should be on page 1 or 2. Also, we used to be sitelinked for "NLP California" and aren't anymore. Notice that "nlpca" splits into "nlp" and "ca" for California. Could you look and see if it is just those 2 sites and if all we need to do is contact them to change to branded anchor text. Or if it's something else to get back our rankings for "NLP" and our sitelinks for "NLP California" Thank you0 -
Drop in domain authority for myself and all my competitors, was something changed?
On the 1/11 report all four websites dropped, and starting on 2/12 they all dropped a few more times. These are all large companies who are completely white hat. Was something changed? The reason I asked is all of our linking C-Blocks dropped as well. Mine dropped from 114 to 42 and I have no idea why. All of my competitors dropped as well, is this related?

Poor OSE results on my links
I am really disappointed with the "return on investment" I am getting from being a Pro member and using Open Site Explorer to analyze and remedy my inbound links post-penguin. My site has been crawled for over 4 months now by seomoz and OSE reprots that I have "external links" from just 25 or so domains - whereas Google webmaster tools has accurately identified well over 270 domains that link back to my site. How can do any sort of link removal strategy using open site explorer? I am paying $100/mo for SEomoz, and nothing for Google. What is the problem?
