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

Shoppers struggle to quickly and accurately compare the true cost-per-unit of products sold in different measurements or package sizes. Manually calculating 'price per pound' (880/mo) or 'price per litre' on the spot is cumbersome and often leads to purchasing the less economical option.

Who experiences it
A shopper comparing different-sized packages of the same product at varying prices.
When it happens
They are standing in a store aisle, holding two different items and trying to determine which offers the better value.
How often
This occurs every time they shop for groceries or bulk goods where item sizes or units differ.
What they do today
They use a general calculator or try to do mental math to figure out 'price per ounce' (1,600/mo) or 'cost per unit' (390/mo), which is error-prone and slow.

Opportunity score 3,893 = 40% contestable search demand (16,660 a month across 25 keywords, after removing 3,740 brand searches) + 25% how open the competition still is (31 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 (no ad pricing) + 10% crowd rankings (Elo 1500, 12 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 4,711 · latest 3,105 · low 2,570 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 (20,400 searches a month), listed below.

Revenue potential

estimate, not a promise

Priced and converted as a hard to charge for directly — the funnel below changes with that model, because a freemium consumer app and a B2B tool convert nothing alike.

Slow build $67Good execution $431Breakout $6,457

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 $6,457 a month by month 24 (1,399 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

  • 20,400 cluster searches a month, 1.6x for app stores and word of mouth.
  • You reach 1.0-6.0% of that, scaled by ad competition 0.00.
  • 12% of visitors sign up, 2% of those pay. Freemium consumer: roughly 1-3% of free users ever pay, so this needs volume.
  • That wins 1-5 new subscribers a month. Stack 12 months of that against 7% monthly churn and you're holding 7-39 paying users by month 12.
  • Price $9/mo, taken from the business model below.

Likely business model

willingness to pay 19/100

Hard to charge for directly

Every one of the 5 competitors we read gives this away free — the money here is attention, not subscriptions.

How rivals make money 5 competitors read: all free or ad-supported.

Price to test · from ad click value

$4–$14/mo

No competitor charges for this. If you do put a paid tier up, this band is what the keyword implies people are worth, not what anyone is proven to pay.

What to charge for

Free tool, revenue on the side: affiliate links, sponsored placements or a paid pro layer for the small slice who use it weekly. Charging at the front door means competing with free.

Willingness-to-pay evidence

  • 5 competitors read: all free or ad-supported.
  • 60% of the 25-keyword cluster is commercial-intent wording (best, app, pricing, alternative).
  • Ad competition 0.00 — few advertisers fighting for it.
