Reverse SEO or Search Engine Reputation Management is the process of putting down the bad reputations or sites in Google.
If you see other websites are doing anything that is against Google guidelines or rules, you can tell Google to penalize the website or down its ranking. You can inform Google if your competitors are not performing as per rules and regulations, this will ultimately down their ranking in the search engine result. Reverse SEO is useful for minimizing the impact of bad publicity within the SERPs. The “bad” pages will be prevented from getting attention.
