Competitor backlinking is a type of online marketing strategy which involves getting other websites to link to your website. By doing this, your website's page ranking on search engines will improve, allowing people to find it more easily. For example, if your website sells hiking gear, you may want outdoor and adventure websites to link to your website when they write about backpacking or camping. Having lots of other websites link to your website will make it look more credible in the eyes of search engines and also helps people to find it more easily.
