Positions are 1 based, so position 1 is the top result. A null position means asobeast checked the keyword and did not find the app within the captured depth. It never means zero.

​
How is a position recorded?

Each check writes one row per app, keyword and UTC date, and stores the depth that check covered alongside the position. The default depth is 200. The row is written even when the app was not found. That is deliberate: an absent row and a null position mean different things, and only storing both lets you tell “we did not look” apart from “we looked and it was not there”.

​
What does null mean?

Checked, and not found within depth. It does not mean any of the following.

​
How is null displayed?

As a bound derived from that row’s own depth, never as 0. A row captured at depth 200 renders as >200, and a row captured at depth 100 renders as >100. Reading the bound from the row rather than from a constant matters, because historical rows may have been captured at a different depth than today’s.

​
How are positions charted?

Ranking charts use a reversed Y axis, so position 1 sits at the top and an improving line rises. A null breaks the series rather than dropping it to the bottom of the chart.
If you consume the API, treat null as absent rather than as 0. Coercing null to zero makes every unranked keyword look like the best possible result and inverts every trend, average and delta you compute.

​
How deep does the SERP snapshot go?

Position checks capture to depth 200. The stored SERP snapshot, which is what powers volatility, entrants and competitor discovery, keeps the top 10 results for each keyword and date.
