In SEOptimer, problematic links are flagged with a “warning” icon on the farthest-left column. This warning icon is shown whenever a linking domain triggers one of these low-quality signals:

  • High Spam Score — The spam score is calculated by Moz to show a website’s likelihood of being penalized. The higher the spam score This is calculated using different spam flags, like a low number of linking domains, a high ratio of “follow” links and so on.
  • Unindexed Website  This indicates that the website isn't currently indexed by Google, which could indicate low quality.
  • Low Trust Flow — In addition to the backlink profile, the Trust Flow also factors in the quality of traffic that flows through links. This metric is introduced and used by Majestic SEO.
  • High External Links — A high number of external links could pertain to a low-quality web directory, sitewide footer links or spam comments.
  • Unnatural Anchor Text — Finally, unnatural anchor texts disrupt the balance of your backlink profile's anchor text diversity. Good anchor texts include your brand name, naked URL and partial keyword matches.

This will bring up the sub-menu where you can specify the warnings you’d like to filter for.

If you want to quickly identify bad backlinks that are potentially harmful, select all the warnings.

After a few seconds, SEOptimer will refresh the page and list all backlinks that trigger the specified warning(s).

Conducting a Manual Review of Bad Backlinks

SEOptimer does an excellent job of apprehending terrible backlinks that must be dealt with immediately.
