Webmasters don't have full control over backlinks that are placed to their site, so you should know your backlink profile and always keep an eye on which new links are created naturally or unnaturally. It is advisable to perform extensive screening and monitor new backlinks via certain tools. This way you can always see which new links are created and can act if necessary. Link Detox is an important step for a clean link profile, which in turn is an important building block for a successful and healthy website. Onpage you can control a lot, but what happens offpage is rarely in your hands.
