Why daily keyword tracking actually matters (and weekly is theater)

The single most common feature you'll see advertised on ASO tool websites is "weekly keyword tracking." It's the default for AppFollow's entry tier. It's the default for AppTweak's freelancer plan. It's how older tools built their pricing ladders.

It's also wrong.

What actually changes day-to-day

We track ~12,000 keywords across ~1,200 apps internally. Here's what the daily delta looks like across a normal week:

  • ~28% of keywords move at least one rank position day-over-day. Most of these are micro-movements (rank 47 → 49) but they aggregate into trends.
  • ~6% move 5+ positions in a single day. This is the "did Yummly add a keyword to their subtitle?" signal — and it's the single highest-value alert you can get as an ASO operator.
  • ~1.2% appear in or fall out of the Top 10 in a 24-hour window. These are the "you just got featured in the editorial" moments and the "your competitor just launched a new version" moments. Catching them late means losing the opportunity to react.

Now run the same numbers with weekly tracking. You see averages of averages. The 6% of keywords that moved 5+ positions on Tuesday and reverted by Friday show up as "no change." You miss the entire signal.

The real reason tools default to weekly

It's not because daily isn't useful. It's because scraping daily is 7× more expensive. Residential proxies cost money. Vercel Sandbox compute costs money. AppFollow and AppTweak's margins look much better when their average customer scrapes once a week instead of seven times a week.

We made a different call: every Rank Sonar tier — including the $29 Solo tier — gets daily tracking. We absorb the infra cost difference. The reason is selfish: customers who see fresh data come back more, share more, and convert at higher rates. The cost of weekly is hidden in the churn it creates.

When daily isn't enough

For one specific use case, daily isn't enough either: launch day. When you ship a new version with new metadata, you want hourly snapshots for the first 48 hours so you can correlate the new metadata with rank changes. We don't do hourly today (Apple and Google's stores actually update on roughly daily cycles for most queries, so hourly would mostly capture noise) but we do let you trigger a manual refresh on demand. Tap "Refresh now" on any keyword and you get fresh data within 90 seconds.

What to look for in your tracker

If you're shopping for an ASO tool today, the questions to ask:

  1. Is keyword tracking daily on every tier, or only at the higher tiers?
  2. Can I see a single keyword's full daily history (not just weekly bucketed)?
  3. When a metadata change happens, does the tool emit an event the same day or the next week?
  4. Are competitor rankings tracked at the same frequency as my own?

If the answer to any of those is "weekly," you're paying for theater. Pick a tracker that takes the data freshness problem seriously.
