Who doesn’t like to be appreciated? Everyone likes appreciation and most of the people are eager to stay popular in the community.
Same is the case with websites and brands, they like to be famous and when they get the opportunity they will not miss it.
You can simply make web content where awards are given to the different brands.
For example; Organic Farming Innovation Award (OFIA) 2019, Home Decors Brand Award, etc.
When a certain brand is being praised on your website, they are going to share the particular content piece on their website. Chances are, they will also redirect their link for that particular blog post.
