CPC is what an advertiser pays Google for one click on that phrase — a rough price tag on how valuable the visitor is. Ad comp. runs 0 to 1 and is how full the ad auction is: near 1 means advertisers are fighting over it (money is there, but ranking is hard), near 0 means almost nobody bids.

Who has the problem

Individuals frequently forget to drink water throughout their day, leading to a scramble to catch up on hydration later. Existing tracking methods demand constant manual input and don't intuitively adapt to their actual drinking habits, failing to provide proactive, context-aware nudges.

Who experiences it
Someone trying to maintain consistent hydration throughout the day.
When it happens
They realize they haven't had enough water in hours, often mid-afternoon or evening.
How often
This realization occurs daily, leading to searches like "daily water intake tracker" (20/mo) or "daily water intake app" (10/mo).
What they do today
People use basic water intake tracking apps (390/mo) or physical notes, but these require manual logging after each drink and often don't provide timely reminders that cease once the goal is met.

Why now

Demand is cooling; build only if you have an angle the incumbents lack.

  • Searches are up 49% year over year

    631 a month twelve months ago → 941 now for "water intake tracking".

  • Cooling 9% over the last quarter

    Last three months of searches against the three before them.

  • Peaks in May

    Demand swings 296% across the year, so ship roughly two months before May.

  • Advertisers pay $2.30 a click here

    Buying this intent instead of ranking for it would run roughly $2,001 a month — money is already chasing these searches.

  • 6 real products on page one

    Alongside 7 articles and reference pages, which is room a focused tool can take.

Opportunity score 4,962 = 40% contestable search demand (2,900 a month across 25 keywords) + 25% how open the competition still is (13 products on page one) + 15% momentum (last three months vs the three before, capped so one bucketed month can't swing it) + 10% willingness to pay ($2.30 a click) + 10% crowd rankings (Elo 1515, 4 head-to-heads, weighted by how many votes exist). Anything we can't measure is dropped and the rest re-weighted, so a blank signal never counts as an average one. Search data refreshes daily from Google Ads via DataForSEO.

Peak 2,031 · latest 941 · low 513 searches a month

Google reports monthly volume in fixed buckets (…27,100 · 33,100 · 40,500 · 49,500), so steady months land on the exact same number. Weekly data isn't published.

This chart tracks the single lead phrase. The demand score uses the whole cluster of 25 related phrases (2,900 searches a month), listed below.

Revenue potential

estimate, not a promise

Priced and converted as a prosumer subscription — the funnel below changes with that model, because a freemium consumer app and a B2B tool convert nothing alike.

Slow build $81Good execution $545Breakout $8,384

The two solid lines are the range above: a slow build and good execution on a slice of this demand. The dashed line is the breakout — you become the default answer for this problem, take roughly a quarter of the intent, convert far better because people arrive already sold, and churn halves. That's the outcome worth chasing, and it's about $8,384 a month by month 24 (1,392 paying users). Most ideas land on the bottom line; the point of the chart is that the ceiling isn't the estimate.

How we got there

  • 2,900 cluster searches a month, 1.6x for app stores and word of mouth.
  • You reach 0.9-5.5% of that, scaled by ad competition 0.29.
  • 10% of visitors sign up, 12% of those pay. Trial-led: people arrive already shopping, so trial-to-paid runs high.
  • That wins 0-3 new subscribers a month. Stack 12 months of that against 5% monthly churn and you're holding 5-28 paying users by month 12.
  • Price $15/mo, taken from the business model below.

Prosumer subscription

People are actively shopping for a tool here, so charge from day one.

Price to test · from ad click value

$6–$24/mo

No competitor pricing page was readable, so this band comes from what a click on this intent costs advertisers ($2.30) — a starting price to test, not a proven one.

What to charge for

Trial then subscribe. This crowd is already comparing paid tools, so ask for the card early rather than running a wide free tier.

What this data can't tell you

  • · Nobody's published price backs this band yet — treat the number as a test, and put a price up in week one to find out.

Willingness-to-pay evidence

  • Advertisers pay $2.30 a click for this intent — real money already chases it.
  • 80% of the 25-keyword cluster is commercial-intent wording (best, app, pricing, alternative).
  • Ad competition 0.29 — few advertisers fighting for it.
