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

Digital notes are taken with good intentions but become unsearchable and unmanageable over time. The effort to store information is wasted when retrieval fails, creating frustration and inefficiency for users who expect 'notes that are searchable months later'.

Who experiences it
A person trying to store and retrieve digital information for future reference, searching for 'note keeping app' (22,200/mo) or 'best note taking app' (6,600/mo).
When it happens
They recall a piece of information they know they saved, but cannot immediately locate it within their existing 'notebook app' (8,100/mo) or 'notes app android' (6,600/mo).
How often
This occurs whenever they need to access a specific detail from a note created days, weeks, or months ago.
What they do today
They use a general 'note app' (8,100/mo) like Simplenote (8,100/mo) or 'Goodnotes' (74,000/mo), but struggle with its search capabilities or organization, making stored information effectively lost.

Why now

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

  • Searches are down 33% year over year

    18,740 a month twelve months ago → 12,528 now for "note taking app".

  • Cooling 52% over the last quarter

    Last three months of searches against the three before them.

  • Peaks in November

    Demand swings 235% across the year, so ship roughly two months before November.

  • Advertisers pay $7.96 a click here

    Buying this intent instead of ranking for it would run roughly $746,489 a month — money is already chasing these searches.

Opportunity score 8,148 = 40% contestable search demand (306,000 a month across 25 keywords, after removing 6,600 brand searches) + 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 ($7.96 a click) + 10% crowd rankings (Elo 1529, 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 41,932 · latest 12,528 · low 12,528 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 (312,600 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 $21,263Good execution $144,551Breakout $2,289,604

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 $2,289,604 a month by month 24 (150,048 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

  • 312,600 cluster searches a month, 1.6x for app stores and word of mouth.
  • You reach 0.8-5.3% of that, scaled by ad competition 0.38.
  • 10% of visitors sign up, 12% of those pay. Trial-led: people arrive already shopping, so trial-to-paid runs high.
  • That wins 51-319 new subscribers a month. Stack 12 months of that against 5% monthly churn and you're holding 468-2,933 paying users by month 12.
  • Price $38/mo, taken from the business model below.

Price to test · from ad click value

No competitor pricing page was readable, so this band comes from what a click on this intent costs advertisers ($7.96) — 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 $7.96 a click for this intent — real money already chases it.
  • 84% of the 25-keyword cluster is commercial-intent wording (best, app, pricing, alternative).
  • Ad competition 0.38 — few advertisers fighting for it.
