It is common knowledge that backlink checkers either report links very late or report them incorrectly.
A link’s index status can be checked quickly and easily in Google. Simply type “site:URL” into Google’s search bar and see if the domain shows up in the results. If it has been indexed, that indicates it is helping to drive traffic to your site.
However, it may take up to three months after you receive your order report for Google to crawl and index these connections.
