I’m familiar with the problem of manipulated bloggers; our team went through it ourselves until we decided to outsource all the work to a dedicated team. From my own experience, I recommend Socialfly, as they’re the best influencer marketing agency . They handle the entire process, like from in-depth engagement audits and negotiations to gifting, seeding, and whitelisting to launching ads on behalf of the bloggers themselves. We launched a campaign with microbloggers with their help and saw excellent ROI and traffic quality. They truly vet every account down to the last penny, so you definitely won’t waste your budget.
