External Followed Links History, number of links go down
-
I was reviewing Historical Domain Analysis and found that in last 2 month we lost almost 10000 external followed links. What this could be? is this real or just question seomoz crawling?
-
It is a function of the volume. I lost about 20% of my links that were industry specific.
-
This explains even more, thanks.
-
Thanks a lot for this. Explain a lot, but still big amount of deindexed sites as for me. Any way thanks.

If you are referring to the latest OpenSiteExplorer index then have a look here:
http://www.seomoz.org/blog/july-mozscape-update
Annoyingly the latest index is about half the size of the one before it so this could explain the loss in links. They say if you had a large amount of lower quality links you could see a big difference in total links as many of these are not indexed anymore.
-
This could be a result where your back links were coming from websites that have been de indexed or banned. Those websites were affected by the updates of Panda most likely. I am not a expert on the subject because I have not had to deal with it directly.. But the dates your links started going down looks about right.

Why are my month old links not showing in WMT or OSE?
Hey Everyone! I've been working hard on boosting my ranking after launching my new site 2 months ago. I realize that this process normally takes some time however I've come across a questions that I'm not sure I know that answer to... I had some really solid back links added about a month ago but nothing is showing up yet in WMT on them. When I run an OSE I don't see any links there (not even under newly discovered). Can someone please help with some insight on why they might now be showing. Is it just a time thing or should I be doing something different?Any insight will be very helpful. Thanks

Finding affiliate links with opensiteexplorer
Hey guys, I'm trying to develop lists of our competitors affiliates using opensiteexplorer using the following method When logged in to seomoz, go to http://www.opensiteexplorer.org/ Search for<rival company="" domain=""></rival> Select Show ALL links from ALL pages to PAGES ON THIS ROOT DOMAIN and SHOW LINKS UNGROUPED Click 'Filter' Click_ 'Download csv'_ Open the csv in excel and filter the Target URL column for any known part of the affiliate link (example ?a_aid) - this leaves you with a list of the affiliate links Filter out duplicates Is this the best process? I have a feeling I'm missing some as OSE truncates to 25 links per domain. It would be nice also if OSE could do the filtering for me. Any better ways to do this?

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?

I have a client with a bit over 100 inbound links but Open Site Explorer shows total links on Subdomain as over 66,000, how can this be?
I have a client www.woodard247.com that shows only a bit over 100 inbound links. using the Open Site Explorer, they are a well trafficed local site and are not doing any grey hat or black hat techniques. However the rankings for their main keywords have suffered recently and we cannot identify any duplicate content or keyword stuffing issues. We have never purchased links or used link building software. Now for the main question: When we run Open Site Explorer it shows only a bit over 100 inbound links on the page and the domain, but the subdomain shows over 66,000 total links! How can this be possible? Could this be a problem? How can I find out what these links are since Open Site Explorer and Seo Spyglass both show only a hundred or so?

Estimating the number of LRD I need to outrank competitor
I just ran a SERP/keyword diffculty report for a keyword I want one of my pages to rank Also, I just conducted the on-the-page-optimization and now I am going to start buidling links. => I would like to estimate how many linking root domains I need to overrank one of my competitor. These are the MOZ data:
Moz Pro | | He_Jo
1. My page:
Page Linking Root domains: 0
Root Domain Linking Root Domains: 151 2. Competitor:
Page linking root domains: 1
Root Domain Linking Root Domains: 5,786 I don't really know on which metric (Page or domain LRD) to rely on in order to make an estimation and I would be glad for some help! To simplyfy the problem, assume that all toher factors (code, on-the-page keyword use., social etc.) are equal for both sites. Can I just get 2LRD to that page in order to likely outrank my competitor or do I need around 5000 more links poiting to my site? I think an answer to this question could help a lot of users here, since I saw similar questions/difficulties regarding the use of page LRD vs. root domain LRD P.S. Non of the pages of my website do currently rank in the top 100 for that keyword.2 -
How can I recognize spammy links that harm my website
Hello, Can someone tell me how I can recognize links that can harm my website? I have OpenSiteExplorer and CognitiveSEO as tools to create nice backlinking reports for me. But my problem is, how do I know if a link shown on these reports can harm my website so I can remove them? Is it linktypes, low auth. links etc? Thank you for your answers in advance! Regards, Thomas

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!
