Links counted in Google Webmaster Tools vs. OpenSiteExplorer
-
Hi all SEOmozzers,
site: http://f8phototravel.pl
I have (in my GMT profile) 43 domains linking. Among them one of the biggest Polish like: onet.pl (5/187), gazeta.pl (8/393), grono.net.pl, canon-board.info, eturystyka.org and other.
They are not present in OpenSiteExplorer.
Any ideas why?
Thanks,
Marek

Thanks Cyrus,
I need explanation how OSE works. Now know it and can wait for next results and work on good link connections. I will try to "flow to surface" with links from good sites in which I have buried links

Marek,
In the past, each Linkscape index started with the top 10 billion urls from the previous index, based on authority, and links were discovered outward from their. Today the process is similar, but the crawling proceeds on a more continuous basis.
Basically, Linkscape still has to discover URL through links. If there are not many linked paths from the top 10 billion URLs to a particular page (even if that page is on a high authority site) then Linkscape won't consider it a priority to crawl.
On the other hand, if there are short, clear routes to a URL, this means even if the page is on a low authority site, it might get included in the index. This is a more natural crawling system that, although not perfect, mimics the way authority is passed in the real world.

Thank you Ryan,
Great explanation. My idea is to make sure how it works and thanks to you i'm enlightened. I always try to understand mechanisms and rules of tools actions.
Thank you again:-)

OSE is based upon Linkscape's crawl of the web. The Linkscape crawl cycle is roughly a month. It takes 2-3 weeks to crawl the web, and then 1-2 weeks to process the large amount of data and provide it in a readily usable format.
When working with OSE it's important to know the Linkscape update schedule. OSE was last updated Jan 17th and will be updated again Feb 29th.
It's also important to understand how the crawler works. If you create a link during a period, you will often need to wait until the next period until the link is visible in OSE. I find OSE to be a fantastic tool for analyzing a site's backlinks. It takes time for OSE, Majestic or any other tool to crawl trillions of web pages and process the data. The tools will always be behind in the foreseeable future.
OSE is being adjusted to crawl deeper. In the past, it only crawled the top 25% of web pages. For the most part, if OSE does not see the link, the link likely has no value.

Where is the linking page located within these sites? When were these links created? Those are the most relevant questions.
DMOZ is a PR 10, DA 10 site. Some pages are buried so deeply that neither Google or OSE crawls them.
In most cases, if a link is not discovered in OSE it is either two new or too weak (including buried links). If you feel neither is the case, you can submit the link information to help@seomoz.org and the help desk team will assist you.

Yes I know majesticseo and I wrote about it some time ago in Q&A What do you use Majestic SEO for?
Frankly speaking my question was a little bit provoking. It's a large number of tools ... each of them cost a money - that can be a problem, not big but...
My question is also about how the OSE crawl the pages/links, how accurate it is and in the end how long it take to crawl e.g. 50% of links?
And still I'm wonder why it crawls low ranked pages and not to crawl high ranked pages on specific market/country?
I really want to understand what is the scheme of OSE crawling work.

Besides SEOmoz, I would recommend Majestic SEO http://www.majesticseo.com/

I would wait and see what OSE says on their next update on the 29th. It looks like OSE crawls those sites, so either they don't crawl deep enough (as deep as Google does), or your links are newer and just not updated yet.
As for a reliable crawl tool, I believe OSE is great, but here is a nice post on a few other international tool. (based on OSE data)

Hi Brent,
I know that, already read lots of Q&A and other stuff ... but the thing is that OSE indexed links from my few domains (C Blocks) and other links from very low ranked sites.
I wonder why it doesn't index links from e.g. Google +1 and other high ranked sites?
It's a second month of campaign and few crawls behind...
It can be an issue for other campaign I want to perform for my clients ... should I use different tool for link tracking?
On the other hand my mR = 5.1, mT = 5.69, PA = 33, DA = 20 and all factors increased heavily last 2 months. At the same time my PR = 3 (from PR=0, 2 months ago)
Thanks

Google's crawler has a separate larger database, crawl rate ect, than OSE.
OSE indexes monthly where as Google's index is updated more often than that.
In short, OSE is just a different "snapshot" of the net then Google's much larger database of the web

Is there a tool on Moz or out on the internet that does bad link checker
I'm still pretty new to this and I was wondering if there is a free software, one of Moz or free out on the the internet that allows you to check bad links. I've done a lot of link building with citations and directories that for my clients industry. I just don't want to add their website and profile to a bad/risky directory and it penalizes my clients. I've seen a few out there, but I need one that is respectable and reliable. Any suggestions? I found one called bad neighborhood http://www.bad-neighborhood.com/text-link-tool.htm. Thanks Again, Benny

Moz vs google data conflict?
Hi there, I am doing an SEO site audit for a client(giveaway, and here is the problem: when performing site:domain.com on google --> 13,800 pages were found When I see this number it seems to be a bit too much compare to the links i checked on integrity(link check for broken links) which gave me a result of 1291. I digged in more into the Google results and saw hundreds(maybe thousands) of pages that are blocked by robots.txt. So I am thinking, ok this is it, thousands of pages can't be crawled by the search engines. Here is the big BUT though, then I check at my moz crawl (see attachment) and no pages are blocked by the SEs, and then look at the dups, only 23 recorded?? Is Moz not crawling properly the 13,800 results that google finds or is this some magical phenomenon happening here? I am really confused here that is why I need some help here! Thank you guys!

Finding a list of all inbound links
Hello. I just used Open Site Explorer to find inbound links to a site. But it does not seem to list all inbound links. I will be changing a lot of urls on the site, and I would like to put in 301 redirects only for the pages that have links to them. Is there a way to find all inbound links and the specific pages they link to? Thank you!

Finding Broken Links
My campaign report says I have a 404 error for a sub page located at domain/products/contact.aspx My contact page is not in the /products directory so what I'm wondering is if this means that somewhere on a site I have a link pointed to /products/contact.aspx. I've looked everywhere and cannot find the link if it is out there somewhere.

What Is he Difference Between Google UK and Google Great Britain
When setting up a campaign for keywords and selected search engines. I am targeting a UK market so obviously Google.co.uk is my main target. However when I set up the campaign i select Google as the SE but it asks me if I want United Kingdom or Great Britain. I selected United Kingdom and it has been returning 0 results for rankings even though I can physically see them in the SERPS. Does anyone know exactly what is the difference between the UK and GB options. I assume I should of specified GB but not sure. Any help would be appreciated. Thanks

Do keywords in drop-down menus count?
In running one of my campaigns in SEOMoz Pro, it was recommended that I reduce the amount of times a keyword is used to 15. On the actual page, there are fewer than 15, but when you include the number of times it is used in drop-downs from the nav bar, the number is 53. I know there is really no hard and fast rule about how many instances of a keyword make for keyword stuffing and the drop-downs only use the term where needed. Without it's use, it would be difficult to navigate the site. Is this a problem or should I focus on more important fixes?

Any ideas about using research tools data to create client interest in dedicating marketing spend on SEO services vs their other current antiquated marketing methods?
I consult in the dental industry. Many professionals in this industry are operating in the dark ages when it comes to marketing. Any ideas about using research tools data to create client interest in dedicating marketing spend on SEO services vs their other current antiquated marketing methods? I am approaching potential clients to pitch SEO. They aren't necessarily seeking SEO services currently but have a strong marketing budget. I would like to use seomoz tools data about their site and competitors as way to show possibilities/potential of SEO services to gain interest in further discussion of SEO benefits.

What is the difference between the link count on OSE and Linkscape?
We notice a huge difference in the number of inbound links . Site explore shows 1,200 as an example and linkscape shows over 100,000 for the same site.
