Hey everyone!
Depending on when we discover your links on those external sites, it can take 2-3 index updates for them to appear.
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 that have high authority. Once we can find those links, we will then be able to crawl your site to find pages you link to and so forth.
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).
Therefore, 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. Check the Just Discovered Links section to see if your link is processing. Links that appear there can take 1-2 updates to show up in inbound links.
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 (our metric). It’s best to use all the tools you can to obtain a full backlink profile.
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. Run a search for those external linking sites and check their domain authority, if it isn't high enough we may not have a reason to re-crawl them to find your new links.
