What I use: If you found my website on Facebook, Instagram, or Linkedin, then you’ve seen the hard work of CoSchedule. As a content creator, I love Coschedule because it integrates directly with my website to help me promote my recent blog posts (& future podcast show notes). It also has a great feature called ReQueue that makes it easy to put evergreen content in a loop (without overshadowing any time-sensitive promotions you’re running).
Lower price option: The best free option is Buffer. The free version can integrate with 3 social accounts and schedule up to 10 posts/mo, but doesn’t have any evergreen content.
