We grab our backlink data from Majestic, which is a very accurate SEO tool.
Majestic will crawl a website and pick up backlinks; these will then be shown in the platform.
It's important to note that Majestic uses a fresh index (backlinks found within the past 90-120 days), whereas often, other tools may use historic data (containing more backlinks that are less likely to be live).
If you cannot see a backlink in the platform that you can see elsewhere, likely, Majestic has not picked this up yet. In this case, we can re-crawl the backlinks to see if this helps pick them up.
