A great point you made there though. Too many people try to take on too much at once and end up spreading themselves too thin – trying to conquer all the niches at the same time. Marketers also do this with advertising. Instead of sticking with one platform until they are generating a consistent number of leads they will jump from platform to platform, in essence chucking a load of crap at a wall and seeing what sticks.
In the past, large affiliates were the mainstay, as catch-all coupon and media sites gave traffic to hundreds or thousands of advertisers. This is not so much the case anymore. With consumers using long-tail keywords and searching for very specific products and services, influencers can leverage their hyper-focused niche for affiliate marketing success. Influencers may not send advertisers huge amounts of traffic, but the audience they do send is credible, targeted, and has higher conversion rates.
