How long do old links stay in Open SIte Explorer stats?
-
Hi,
In Open Site Explorer has around 2000 External followed links which would be great if it was true. I think the issue is that before my site wasn't appending slashes to the url so I think it was counting links from http://mydomain/page1 to http://mydomain/page2/ as an external link (could be wrong here). I corrected this a couple of months ago but I still seem to have over 2000 External links. When I look at the linking pages many of them are "sans slash" and have old anchor text in the link.
How long does it take of OSE to update these stale links it there any way I can prompt it to take aciton?

Thanks Cyrus, thats made things clear.

The Linkscape index, which feeds Open Site Explorer, is updated every few weeks - or on average about once per month.
You can find a calendar of the updates here - http://apiwiki.seomoz.org/w/page/25141119/Linkscape%20Schedule
Here's how the process works: The Linkscape crawlers explore the entire web - this generally takes at least 2 weeks. Then another couple of weeks are spent processing this information (it's a lot of processing!) So in theory, by the time it is released, the index could contain some links up to 3-4 weeks old. In edge cases, for example it's been 3-4 weeks since the last update, the links could be up to 6-7 weeks old.
Only links that were found in the last crawl are included. Unfortunately, there's not much you can do to speed this up.
That said the vast majority of these links will still exist. Linkscape has built in biases for links with permanence. This helps deal with the fact that 50% of the web disappears every year.
Hope this helps! Best of luck.

Automatically Check List of Sites For Links To Specific Domain
Hi all, Can anyone recommend a tool that will allow me to put in a list of about 200 domains that are then checked for a link back to a specific domain? I know I can do various link searches and use Google site: command on a site by site basis, but it would be much quicker if there was a tool that could take the list of domains I am expecting a link on and then find if that link exists and if so on what page etc. Hope this makes sense otherwise I have to spend a day doing it by hand - not fun! Thanks,

Can you explain social indicators in Open Site Explorer
My Google +'s for my domain were 403 last month and 35 this month.... Based on this I'm assuming OSE's numbers are not cumulative. Are they based on the previous month or a different time period? Any explanations would be helpful. Thanks!

Why are my external links not showing?
I've had Pro long enough to get at least two weekly crawls and yet no external links are showing (which do absolutely exist). Why would this be?

Strange nothing site ranking
Hi There. If you check who ranks for "credit cards" there is a website https://www.woolworthsmoney.com.au/ that is in position #5 This is a highly competitive keyword, but OpenSiteExporer.org cannot give me any backlinks for it. it says "No Data Available for this URL" The same thing happens in Market Samurai - no data 1. What are these guys doing that the others are not? 2. How come OSE can't pull any data for it?

OPen Site Explorer listing criteria?
Checking link data for a potential client who has given me access to their websmaster tools account, I've noticed that Google list over 150,000 "Links to Your Site" but yet OSE only reports a tiny fraction of this number.
Moz Pro | | G-DC
I have manually verified that there are in fact direct links from the sites that are listed in Webmaster Tools but not in OSE. Does OSE discard some links? Is there a reporting lag? Does anyone know why there would be such a large discrepancy?0 -
Is there any alternatives to Yahoo Site Explorer?
Hi, Is there any alternatives to Yahoo Site Explorer? I want to find backlinks of some unavailable pages and YSE was a great tool to deal with. But when I used tools like Open Site Explorer, ahrefs.com etc., I couldn't find one same like YSE. Because when I tried, it shows'No data available for this URL' where on YSE I found inbound links. What Alternatives Are There? thanks in advance!

Link Blocks
Sorry, perhaps a noob question. In relation to site explorer, have also searched and unable to find any information, wondered if anyone could advise as to what "Linking C Blocks" are? Found under the "Compare Link Metrics" tab. Thanks in advance. Lee

Reg. internal followed links
Our site is new. So far we have a 534 pages. Our competitors have around 5000. I'm working on building more, but that's a lot of catching up. The report says we have only 174 internal followed links. Why is that? I have all links set in the site to be nofollow links, but not the inside links. I also have lots of landing pages, which are not added to the main menu, obviously. But the the main menu shows up on all landing pages. Just wondering if either the nofollow has anything to do with it or the landing pages set up, or the numbers are accurate. Any ideas? Thanks!
