If you are working with sites like jokes, status, greetings, etc, You might have to work harder in Off-site SEO. Working in backlinks, authority helps alot as there is not much to add value.
Note: A good internal linking plan or silo structure helps to drop the bounce rate of the sites eventually ranking your posts higher.
Moreover, You can also try adding some extra content even to the jokes which is unique i.e what your competitors lack. For Eg: Funny images in jokes.
