Cleaning up link profile
-
I've recently been trying to tidy up my link profile. We have been link building for a number of years and I decided to check it out and see how good our profile looks.
I used OSE to give me a report of all external links pointing to pages on my www sub-domain. The results are scary!
I have hundreds of links point to my site that originate from URLs such as the following url which attempts to start a download, use caution!!!
<colgroup><col width="768"></colgroup>
| http://ftp.codeweavers.com/pub/crossover/cxlinux/demo/install-crossover-pro-demo-9.0.1.sh?m=pc&a=bookmarkList.view&target_user_id=1&search_type=tag&keyword=減量 |Another example (this one attampts to start a .jar download!! Be cautious)
<colgroup><col width="794"></colgroup>
| http://www.breastreconstructionguide.com/compare.jar?page=1892&username=DXDZSW |All the other metrics reported for the offending URLs seem ok, such as PA and DA. Also, many have meaningful page titles (as opposed to random characters) and nicely formed anchor text.
What I'd like to know is;
Are these links having a detrimental effect on my SERPs?
How does OSE find them since its a URL to a download?
Has anyone else had a similar experience?
Thanks for your time.
Regards
Aran

Hi Aran,
Some of the links are gone from this latest crawl, more will be gone in November, and they should be almost all gone by December. See Rand's post at http://www.seomoz.org/blog/november-2011-linkscape-update.
As I noted in the September index update, we have had some serious issues when crawling deeper on large domains and encountering binary files that contain code our crawler recognizes and treats as a link. To help stop this problem, we applied a black list to this index to stop a large number of the files folks had reported to us (our estimate is that ~40% of binary files are now removed). However, we know there's still more than a few of these in the database of links so we'll continue cranking away on solutions to remove them all. Our hope is to have them reduced in the next index (November) and nearly eliminated by the December index. If you're ever curious about the next/previous updates, you can always see data for them on our Linkscape calendar.

Thanks Keri, any ideas when the crawler will be bug free?
Its no fun trawling through thousands of links to weed out the dodgy data before I can rpesent the info to a client.

Hi Aran,
First, Don't Panic! You're actually seeing a bug in Linkscape/OSE that we're working on eliminating. What's happening is that as we make deeper crawls, the crawler is finding more downloadable files and chocking on them, and wrongly categorizing them as links. One of the Linkscape engineers has a good explanation over on this thread at http://www.seomoz.org/q/how-are-our-competitors-getting-these-inbound-linking-domains.
Hope this helps, and so sorry for the confusion.

Hi Aaron,
First let me say that sometimes competitors will try to point spammy links to your site (they hope that the bad links will hurt your serps). Usually this will backfire on competition, and the links can actually help your serps. If you have a healthy domain age, and other legitimate links pointing to your site, Google shouldn't penalize you.
My best guess is that Google will just ignore the links that are low quality, but I don't think they will actually hurt you.
You can always submit a Google Webmaster Spam Report from your webmaster's account. Just explain to Google that you were not involved in setting up the links, and the you did not pay for them, nor do you endorse them.

GA Profile - Change UA code
Hi I have two sites under one account in GA. The two sites have the same UA code but with different suffixes (-1 and -2). I want SEOMoz to only track the -2 site but I am unable to enter the UA code directly. Is there a way to do this, or do I need to set-up a new account in GA? Any help appreciated. Chris

NoFollow Links from Subdomain to root domain better than DoFollow Links?
Our service at fotograf.de is a shopsystem for professional photographers. The customers can build their own website with our tool including an onlineshop to sell their pictures. Here is my question: One part of the customers use subdomains of our site like photographers.fotograf.de. On each customer website we include a backlink to our homepage www.fotograf.de. From SEO view is it better to set these links as NoFollow Links? Or should we put one Follow Link on the starting page on each site and on the other pages only NoFollow Link? Are these links bad for our SEO regarding link diversity because they all come from one root domain? Thanks for the answers! Sebastian

How can I download all the inbound links to my Site?
Hi, From Site Explorer, I want to download all the inbound links linking to my site: www.comm100.com/livechat/. But it seems that there is a limitation. I can only download a part of the inbound links? What should I do? Or is it because my account is free trial? Do I have to pay for it? Please help. Thanks,

What analysis exists for Out Bound Links (OBL) from your site
Hi Maybe I am missing this but I can''t seem to see it. I am doing some analysis on a client's site and want to get a csv list of links from the client's site to external sites. So what I am looking for is a list of Out Bound Links (OBL) from the client's site. I want to run these past a black list / bad link neighborhood checking script I have. This would actually be a nice feature in SEO Moz Pro, unless it actually already does and I am just missing it or not setting filters correctly. Thanks Trevor

Can someone explain why I have been seeing an increase in the number of Linking Page URLs in OSE that link directly to downloads?
Ever since the last couple Linkscape updates when doing competitive back link analysis I have noticed a large increase in the number of URLs of Linking Pages in OSE that result in an immediate file download. The majority of the time these downloads are not common files ie PDF, DOC files. For example, these were all in a competitors back link profile: http://download.unesp.br/linux/debian/pool/main/i/isc-dhcp/isc-dhcp-relay-dbg_4.1.1-P1-17_ia64.deb http://snow.fmi.fi/data/20090210_eurasia_sd_025grid.mat http://www.rose-hulman.edu/class/me/HTML/ES204_0708_S/working model examples/Le25 mad hatter.wm?a=p&id=145880&g=5&p=sia&date=iso&o=ajgrep These are just a few I came across for a single competitor. Is this sketchy black hat SEO, some sort of error, actual links, or something else? Any information on this subject would be helpful. Thank you.

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

This been there for 7 months They are gone...Now i have these 2 new backlinks both pr8 and pr9 not showing up in the top of the list..They are both cached .I can see them in the cached links .. ** But where the heck is my new links ??? been about 1-2 months ..shoudnt these show up in the top of open site exploreer??

Does OSE Anchor Text Distribution CSV include internal links or external only?
Quite often when I'm using OSE and perform a CSV export, it looks like the total inbound link count and many phrases come from internal links for the domain in question. I haven't had the time to try and figure this out and don't know exactly how to go about figuring it out. So the initial question is does OSE's anchor text distribution CSV include internal links or are they external only? And alternately, how do I test for this? I deal with sites that have tens or hundreds of thousands of pages and hundreds of thousands or millions of links...
