Closed loop

A closed loop is a content process where every result and every piece of feedback feeds the next plan, as opposed to an open loop, where effort goes in and nothing comes back. Rankfield's own mechanic — research, make, post, measure, learn — is one.

The opposite is not doing nothing; it is posting on a schedule and glancing at the numbers afterward without ever letting them change what gets made next. That is a schedule, not a loop.

None of the four habits that close it are difficult on their own; what makes a loop closed is doing all four in order, every week, including the one that feels obvious to skip.

Most accounts already do the first three steps of a closed loop without thinking about it — research, make, post. What is missing is almost always the last two, measuring against a baseline and letting that change the next plan.

A common way a loop looks closed but isn't: an account checks the numbers after each post out of habit, without ever letting a result change what gets planned next. Reviewing performance is not the same as closing the loop on it — the loop closes only where the review actually changes the next plan.

Skipping the last step is the easiest one to miss, because the first three feel like doing the work: research, make, post already look like a strategy from the outside. What separates a closed loop from a busy schedule is whether an account can say, honestly, what last month's results changed about this month's plan.

Where it comes from

This is Rankfield's own vocabulary, and the product's first blog post is written entirely around it.

If nothing you learn from a post changes the next one, you are not running a strategy. You are running a schedule.
