Why do links appear then disappear month to month?
-
What I mean by this is, a link to my site shows up in the August mozscape crawl, then the next month it doesn't, but its still an active link on the website.
Once a site is crawled, shouldn't it always be there from now on?

If you need more complete backlink data for your site, use Google Webmaster Tools and/or Bing Webmaster Tools.

Thanks for the responses. I find it very frustrating that it acts the way it does. Makes it very difficult to explain to the bosses and to give the data any real value. Though I understand the challenges of it all.
Which is why I usually just talk about rankings, if we're beating our competitors in the rankings, then really who cares if they are supposedly beating us in domain authority and such other factors.

Also, SEOmoz doesn't necessarily crawl the same set of URLs each month. Even if index sizes are the same, some URLs get dropped and some added each month.

Rand said on the latest update that
"This index is about 9 billion URLs smaller than our prior September index: http://www.seomoz.org/blog/september-mozscape-update-is-live, so on average, seeing raw link counts drop ~8.5% wouldn't be surprising."
He also said they would like to get to 150B urls but may get down into the 40B range until some issues are sorted.

I would say that's the difference you're seeing.

Inbound Links Warning
I got the following error about our domain name in Link Explorer. "You entered the URL freexy.net which redirects to youlovelife.com/?domain=freexy.net. Click here to analyze youlovelife.com/?domain=freexy.net instead." Can you give me an advice about this problem?

Joomla Opencart Duplicate Link Issue
With a few recent catalog changes my client is having tons of duplicate content issues. The most peculiar is one that I cannot see visibly on the site pages. This page: http://www.CLIENTDOMAIN.com/catalog/lights.html shows to have several duplicate content issues with URLs such as: http://www.CLIENTDOMAIN.com/catalog/lights/Lamp-DRW.htmlhttp:/www.CLIENTDOMAIN.com - where the domain is basically added to the end of the first URL. Has anyone seen this? Any fixes, plugins or thoughts? Thanks,

Why are inbound links not showing?
I run the site http://www.eurocheapo.com and am finding that many inbound links are not showing up in OSE and on the toolbar. For example, check out this hotel review: http://www.eurocheapo.com/paris/hotel/hotel-esmeralda.html In OSE it shows only 2 links (from 1 domain), which is crazy. It has dozens of inbound links from many different domains (links:http://www.eurocheapo.com/paris/hotel/hotel-esmeralda.html). I notice this all over my site. Pages that we link between are also showing no internal links -- which is easy to disprove. Was there a problem with this crawl? Or is the problem in our code? Many thanks for your help, Tom

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 -
Crazy competitive link analysis, 1 - 40 - 38
I'm seeing very strange results on my competitive link analysis. It used to give me a fairly constant domain authority of 38, now one hour i'm seeing 1, then 38 then back to 1 but if I look in opensite explorer it says I have 40. The same weirdness is having to every other stat in the section both in the overview and more detailed section. The same thing is happening with one of the other competitors i'm comparing my link profile with. What's going on?

How can a competitor show no internal links?
I'm comparing metrics between my site and competitors. Statistics on Site Explorer show that one competitor has no internal links. How is that possible? http://screencast.com/t/P9WX7R9hpdD Thanks for your insight. P9WX7R9hpdD

Open Site Explorer Question- Link Value?
One of my backlinks is from a site that has a page authority of 74. However, the domain is a domain I purchased and 302'd to my current main domain. What I'm wondering (without getting into why a 301 is better than a 302) is this: does OSE have any tool that shows if there is actually value in a link? My assumption is that despite this domain having a PA of 74, the 302 is not passing over any value. To be clear, I understand that a 302 doesn't pass over any SEO value, but my question is whether or not OSE shows the value of a link? Thanks!
