The After Noise Reduction count represents the next stage in the long awaited backlink fidelity project. Soon, non-notable duplicate links will be removed from the Majestic Fresh Index. This reduces the amount of pre-processing required to extract maximum utility from Majestic data.
Removal of this data will be performed gradually.
Once we start to remove links, the External Inbound Link count will become closer to the After Noise Reduction total. Once these numbers are close enough to make the new number redundant, the new total will be removed.
Noise-reduction will take place in the Fresh Index only. Eventually, with the noisiest links deleted, we will be able to improve processing times, widen the index to include more Referring Domains, with deliberately lower numbers of backlinks per domain.
Historic Index will continue to archive all links that we find, and its backlink counts are not affected.
Majestic now performs link level duplicate analysis. This works on a Referring domain level. Similar links to the same resource on different parts of the same site can be marked as "Duplicate" links. Unique, one of a kind links and the best example of a copied link are marked as "Distinct". The results are shown on the right.
You may notice a that there are two different categories of Duplicates. Links that pass Trust Flow or Citation Flow are considered Notable. The "Non-Notable Duplicate" links are considered low value to the majority of Majestic users. These links have been targeted for removal in future index builds.
We look for similar links to the same URL on different parts of each Referring Domain. Links that are similar are marked as 'Duplicate'. Links that are unique, or the single best example of a group of duplicate links, are marked as 'Distinct'.
There are two categories of duplicates. Duplicate links that pass Trust Flow or Citation Flow are considered Notable. Links without Flow Metric scores are considered Non-Notable, and of low value.
Non-notable links are targeted for removal in future builds.
