Broken Link Building SEO

It's a kind of research process where you search about those websites which are similiar to your domain and have given backlinks to other sites which are no longer opening or dead. There will be many websites who might have linked to other websites on their websites and at present those links are not working.

So, you can build similar good content and request the website owner to replace it with your link. Your request might not be accepted by many but even if few accepts your website post then that is the win situation for you.
