Baseline

A baseline is an account's own recent median — typically its last twenty to thirty posts — used as the line every new post is measured against. "Good" only means anything relative to it: a result compared to no baseline is just a number.

A baseline is personal to the account it comes from. A post that beats one account's baseline can sit below another's, which is why an industry average answers a different question than the one that actually matters on Monday.

A baseline moves as an account posts more, which is the point: the line an account is measured against should be its own recent form, not a fixed number set once.

Because it is personal to one account, a baseline cannot be borrowed from a competitor or an industry figure quoted elsewhere; the only number that tells an account whether this week beat its own last month is one built from its own posts.

A common mistake is comparing a single post against a competitor's number or an industry figure instead of the account's own baseline — a post can beat every other account's average and still be a below-baseline result for the account that made it, and the reverse is just as easy to get backwards.

Cadence and baseline move together in practice: an account posting often enough builds a baseline worth trusting within a few weeks, while one posting rarely is comparing against a median built from too few posts to mean much. A run that returns a first pass with no baseline yet is not broken — it is honest about what a handful of early posts cannot tell it, and the confidence attached to that first pass says so plainly.

Where it comes from

This is Rankfield's own vocabulary, not a platform term, and it is the idea the product's first blog post is built around.

The baseline matters more than the count: without a median to compare against, a hundred posts teach you as little as one.
