Hi there! I'm sorry your links aren't showing up in Open Site Explorer yet. I'll try to explain a few reasons why this might be happening:
There are two types of link data we capture: external and internal linking pages. In order for us to discover backlinks to your site, we need to crawl the sites and pages linking to you. Once we can find those links, we will then be able to crawl your site to find pages you link to and so forth.
If you don't see any internal links to your page, make sure we're not blocked from crawling this URL or site. If our web crawlers are blocked from crawling certain pages (i.e., with "noindex" or Robots.txt), they may not be included in the index.
For some more in-depth info, here's how we compile our index:
- We grab the most recent index.
- We take the top 10 billion URLs with the highest MozRank (with a fixed limit on some of the larger domains).
- We start crawling from the top down until we've crawled 90,000,000,000 pages (which is about 35% the amount in Google's index).
So, if the site is not linked to by one of these seed URLs (or one of the URLs linked to by them in the next update) then it won't show up in our index.
Other tools, such as Webmaster Tools, Ahrefs, and Majestic will alway show more link data as they target the quantity of links, while OSE focuses more on quality and Domain Authority. It’s best to use all the tools you can to obtain a full backlink profile; I've got a post here that details why and how that is!
Mozscape focuses on a breadth-first approach. Therefore we almost always have content from the homepage of websites, externally linked-to pages, and pages higher up in a site's information hierarchy. However, deep pages that are buried beneath many layers of navigation are sometimes missed and it may be several index updates before we catch all of these.
We update once a month and you can view the next scheduled update here: http://moz.com/products/api/updates
Hope this helps provide some clarity. Please let me know if you have any questions - thank you!
