You will choose hashtags that are small, medium, large or very large by comparing the engagement rates found for each hashtag to the engagement rates of your publications. 

  • The small hashtags = small compared to your average commitment / choose one between 5-7 hashtags
  • The medium hashtags = the engagement rate is between your average engagement rate and your BPP (Best Performing Post) / choose 5 
  • The large hashtag = the commitment rate must match the average rate of your BPP or be above / choose the 3 biggest hashtags
