Why does Seomoz report other values then Google Webmaster?
-
Dear Seomoz Community
I check my Seomoz ranking from time to and today I saw a big discrepancy between the reported domains linking to my site in the Site Explorer and Google Webmaster tools.
Seomoz reports 19 linking domains
Google shows 150 domains linking to my site.Is there an explanation for this discrepancy?
Thank for helping me out

Hi Menelik,
The explanation is that we are separate from Google, and have our own servers and crawlers. Our server farm isn't nearly as big as Google's, and doesn't crawl as fast. Open Site Explorer updates about once a month, and won't show you all of the links you see in GWT. However, we do add more information than you will see in Google with regards to metrics, and you can see link profiles of other sites that you do not own and have not verified in GWT.
Hope this helps!

Also, Open Site Explorer updates every 60 days.. (I read that somewhere...)

Its impractical to think that data sets from 2 places will be the same in fact if you took the dat that bing had vs google its going to be different what you have to do is choose one tool to set a baseline and then watch the improvements

I can't officially answer this but I believe it's due to Google's reach of tracking links to be much more vast than SEOMoz's current capacity, despite itself doing a very good job.
If the difference is as big as that I'd be willing to bet that the majority of your links are coming from unseen blogs that Google has found and SEOMoz have not.

About 30days free trial for SEOmoz Pro

Duplicate page report
We ran a CSV spreadsheet of our crawl diagnostics related to duplicate URLS' after waiting 5 days with no response to how Rogerbot can be made to filter. My IT lead tells me he thinks the label on the spreadsheet is showing “duplicate URLs”, and that is – literally – what the spreadsheet is showing. It thinks that a database ID number is the only valid part of a URL. To replicate: Just filter the spreadsheet for any number that you see on the page. For example, filtering for 1793 gives us the following result: | URL http://truthbook.com/faq/dsp_viewFAQ.cfm?faqID=1793 http://truthbook.com/index.cfm?linkID=1793 http://truthbook.com/index.cfm?linkID=1793&pf=true http://www.truthbook.com/blogs/dsp_viewBlogEntry.cfm?blogentryID=1793 http://www.truthbook.com/index.cfm?linkID=1793 | There are a couple of problems with the above: 1. It gives the www result, as well as the non-www result. 2. It is seeing the print version as a duplicate (&pf=true) but these are blocked from Google via the noindex header tag. 3. It thinks that different sections of the website with the same ID number the same thing (faq / blogs / pages) In short: this particular report tell us nothing at all. I am trying to get a perspective from someone at SEOMoz to determine if he is reading the result correctly or there is something he is missing? Please help. Jim

How to set the crawler or reports to ignore
I have a mobile version of a site with a URL string that disables the mobile view on smartphones (view full site), string is like this example.com/page-name.html?mobile=off I need the seomoz pro reports or crawler to ignore it because the crawler visits both versions of the site then reports them as duplicate content. Is there a setting page I haven't visited yet that will set this?

SEOmoz crawler and duplicate content
Does anybody know if the SEOmoz crawler picks up canonical tags when its looking for duplicate content? I've got a ton of errors in one of my projects even though they all have canonical tags. Thanks!
