With influData, you can get a visual representation of how an influencer's followers have evolved over time. We have been collecting data from most influencers since 2018 and update it once a week to once a day. The graph can also be useful to look out for possible spikes - rapid growth and rapid decline - that may indicate unnatural activity (such as fake followers).
Tip: Look for natural growth, because this is a good way to predict an influencer's reach. If the number of followers is stagnant, you should be careful and find out why this account has stopped growing. Declining follower numbers are usually a bad sign and incluencers with such numbers are unlikely to be suitable for collaboration.
