In case you have a list prepared for your business competitors, all you have to do is to find their website URLs and a free backlink checker tool created by DM Challenger to get the backlinks made by your rivals and use them to improve the ranking of your website.
If you don’t have the list prepared, google some of the top-rated keywords of your niche and note down the top-ranked website URLs and repeat the above process.
Here are some tools that I have been using for my competitor’s backlink analysis, some of them are free, while some are paid:
