Use the Broken Link Building Method
For small bloggers and businesses, it can be difficult getting that type of boost.
There are many different ways to find dead sites with backlinks. One of the most effective ways to find dead sites with backlinks is by searching for a topic in Ahrefs Content Explorer. You can filter for broken content and set a referring URL filter with a minimum 10 value. This will bring up dead pages with backlinks on at least 10 websites.
It is important to only list the directory sites that are used by people, like Google My Business and Yelp. You can also benefit from other niche directories, as well as the famous ones.
It is important to do your research before you give money.
