C-Block domains OSE
-
hi all quick question regarding c-block domains
OSE tells me we have 70 c-block domains with a total 130 root domains, is it telling us 70 root domains re c-blocks as this is near impossible for us
are c blocks listed as root domains or just links
-
Hi Will,
A C-block is part of the IP address of a website (xxx.xxx.CCC.xxx), for example, with my blog, the IP address is 173.248.188.141 - the c-block is 188.
Usually, websites that are all hosted on the same server have the same c-block. This is a way that Google can detect link-farms, where loads of sites are set up on the same server and used to link to your website. This is why it is good to have diversity in the amount of linking c-blocks.
Inevitably, you will have some identical c-block links but that's ok (and is completely natural). In terms of the links to your website, you have links from 130 root domains that are made up of 70 unique c-blocks. This ratio is perfectly fine, so don't worry.
Hope this helps.

Domain Authority Goes Down After Https change
We just moved our domain from http to https. We have been at a solid 89 for domain authority for the past year, but this month we are now at 88. Does changing to https cause the domain authority to go down and is this just a temporary fluctuation?

Parked Domains and Local SEO
Hi, I wanted to know what your thoughts were on **Parked Domains **and Local SEO. I came across a company that has a lot of parked domains that were created for different countries. i.e. xxxxx.co.uk, xxxxx.ch, xxxxx.com etc. The content they load are from the main domain xxxxx.com I went to a country specific Google search, for instance google.co.uk and google.ch Searched for the company name and xxxxx.com showed up, not the parked domains that existed for each "country" No analytics exist as the tracking code is on xxxxx.com so I can't see if any specific traffic goes to xxxxx.ch, or other domains. From my understand, parked domains lead to unnecessary duplicate content. So why have them? Simply setup a redirect to xxxxx.com from the parked domain. But are there benefits for Local SEO? Search engines like google will still see the domain as a separate entity if no redirect is in place. If so, I realise content has to be unique..but it raises a question... Why have parked domains at all apart from stopping your competitors or users typing other variance of your URL? What do you guys think?

What period of time do OSE social media metrics represent?
When one hovers over the social media metrics in Open Site Explorer the popups say that the numbers represent the total number of times the URL has been posted, liked, tweeted or +1'd. Those numbers are [appear to be] more dynamic than the data in OSE's other reports and seem to get a fresh analysis each time the URL is entered. So I'm wondering what period of time is it counting in it's "total number of times" determination? If I'd like to track the data to get an idea of, say, total number of Facebook Shares for a one month period, how often should I check the numbers?

Scrolling in OSE
Hi Guys, Is anyone else having issues when scrolling in OSE remembering what the column headers are? Just throwing out a suggestion for the next OSE update, could the column headers remain at the top of the links table when scrolling? This would be very useful especially on the top pages table which now has many columns! Thanks guys! Danni

Press Release - using moz bar/OSE is reading domain not page? How? Why?
A question posed by Christopher Glaeser from early today:low PA high DA, had a follow up response from him providing 2 urls from PR WEB for separate press releases: http://www.prweb.com/releases/2011/11/prweb8923419.htm (HP White) On moz bar Page Analysis/Link Data = PA - 47 DA - 36 http://www.prweb.com/releases/2011/12/prweb9051351.htm (Golfer's Advice) On moz bar Page Analysis/Link Data = PA - 1 DA - 96 I kept scratching my head as to how a press release of 6 weeks ago had garnered such attention from a company that would not seem to have a huge traffic due to more obscure product offering and scientific subject (Analyses of Armor Industry versus Golf Advice).

Then I realized that for HP White, Link Data was not about the PR. The url from mozbar was HPWhite.com not the above, I did not notice until I used OSE where same thing was happening. When I cut and pasted the above press release url for HP White and placed it in OSE this changed: PA - 49 DA - 96 (2 links 2 linking root domains) For Golfers advice (0 links from 0 linking domains) Note to all: the links to the PR WEB release for the HP included a low end directory type link and a link from PR WEB (. For Golfer's Advice there was not a link back to the release from PR WEB: Note that Golfer's Advice is a newer release (6 weeks). So, any link from HPWhite release would equal more juice to HP White and PR Web and Vocus. Any link to Golfer's Advice from release offers......???? to Golfer's Advice and who cares to Vocus and PR Web. So, I guess this begs a couple of questions: Why the mozbar link analysis difference for one versus the other? Does PR Web treat some differently than others? Who benefits most from me paying a PR Web to do press releases for a client, PR Web and Vocus or my client and I???? I have tried to order the images to make sense: L to R top, then bottom is last.

Why is there such a difference between Open Site Explorer and Domain Analysis?
When I look at my links in the Competitive Domain Analysis and I see I have 113,018 Ext followed links but Open Site Explorer shows 3,148. Why is there such a difference? In addition, is there a way to view the External Followed links? I want to see where these 113,018 links are coming from. Thanks, Josh

Strange Links in OSE
Hey seomozers, The most recent Linkscape update has created some strange links to our domain. They are links which when I navigate to are download links, here is one example: http://mirror.centos.org/centos/4.9/updates/x86_64/headers/kernel-largesmp-0-2.6.9-89.0.25.EL.x86_64.hdr Now this links has nothing to do with our site and I can't see how it would count as a link to our domain, can anyone shed some light on why these types of links are being crawled as a link to our domain? Thanks Nigel

Filtering OSE Results
Issue: When I export OSE Linking Pages results to .CSV, I'd like to filter only unique domains. It seems to me that there should be a way to do this with Excel, perhaps pivot table. Anyone have a quick solution for this? Alternatively, I can use Linking Domains, which gives all unique roots, but then i lose follow/nofollow filter. Thoughts?
