If you collect business cards at a trade show, make sure all have follow-up within 72 hours.

If you have a website connect it to Google Analytics, create objectives and follow up every week. Or better yet, have reports automatically emailed to you with services like Sumall.

Most social media platforms will also generate reports for you to have an overview of how your community is doing. If not, third party apps like Hootsuite can generate and email you engagement reports.
