A keyword rank moved. Now what?
A third of all keywords move every day for no reason at all. How to tell a wobble from a step, a slide or a cliff, and the one habit shared by the apps that climb.

The morning email says “habit tracker” went from #14 to #11. It is tempting to do something about that. Usually the right response is to do nothing for three days, and this post is about telling the two cases apart.
Ranks wobble on their own
We track 152,000 keywords across the US App Store, each one checked once a day. On an ordinary day about a third of them move by a place or two with no release, no price change and no new ratings behind them. The store reshuffles. Competitors ship. A seasonal app wakes up.
So the first question is not “why did it move?” but “is this bigger than its usual wobble?” A keyword that sits between #9 and #13 all month has not told you anything by landing on #11. Ascent draws a faint band around each keyword’s last 30 days for this reason, and only marks a move in the email when it leaves the band.
Three moves that mean something
A step that holds. The rank jumps and then stays within a place of its new position for four days or more. This is what a real change looks like, and it nearly always lines up with something you did: a release, a new subtitle, a burst of ratings.
A slide. One place down, most days, for two weeks. No single morning looks alarming, which is why slides get missed. They tend to mean a competitor is steadily collecting ratings faster than you are, or that your last update is getting old.
A cliff. Ten or more places overnight. Check whether the keyword is still in your metadata before you check anything else. In our data, a little over half of all cliffs trace back to a title or subtitle edit that dropped a word by accident.
Line it up against your releases
This is the whole reason ranks sit next to release dates in Ascent. A rank chart alone is a line. A rank chart with “2.4.1 shipped” marked on it is an explanation, or at least the start of one.
Riley Chen at Northpaw changed one line of metadata in version 3.1, moving “dog walk tracker” from the keyword field into the subtitle. The rank went from #31 to #8 over nine days and stayed there. Without the release marker that would have looked like luck. With it, Riley did the same thing for two more phrases the following month. The whole story is here.
Apple weighs the title most, then the subtitle, then the keyword field. That much is widely agreed. How much each one weighs is not published, and we would be wary of anyone who quotes a number.
What to actually do
- Wait three days. Unless it is a cliff, a move younger than that is not yet a fact.
- Look for the release marker. If the step starts within two days of a version going live, read that version’s notes and metadata changes before anything else.
- Check ratings volume. A week with twice your usual ratings will lift most of your keywords together. If everything rose at once, it was probably that.
- Change one thing per release. If you rewrite the subtitle and swap six keywords in one update, you will see that something worked and never learn which.
The developers we see climb steadily are not doing anything clever. They change one thing, wait two weeks, write down what happened, and do it again. It is slow, and after a year it is twenty-odd experiments, which is twenty more than most of the apps they are climbing past.
