A plain-English check-up for small business owners paying for Google Ads: a guided audit walks them through whether conversion tracking is set up correctly, what counts as a lead, and how many leads became paying customers, then calculates their real cost per customer and the break-even point for their average job or order value.
The problem people are complaining about
On Oct 27, 2026, a thread titled “Small business owners who've run Google Ads: how do you know if they're actually working?” reached #26 in our daily ranking of small business problems on Reddit. The thread was posted in r/smallbusiness. Ads Truth Check is aimed at that need: a plain-English check-up for small business owners paying for Google Ads: a guided audit walks them through whether conversion tracking is set up correctly, what counts as a lead, and how many leads became paying customers, then calculates their real cost per customer and the break-even point for their average job or order value.
Who the customer is
Plumbers, cleaners, clinics, law offices, landscapers and small online shops who run Google Ads themselves or through a cheap agency, see clicks and 'conversions' in the dashboard, but can't tell whether the money is bringing in real customers. Often phone calls aren't tracked, form fills are counted twice, or 'conversions' include page views. They want a simple answer to one question, is this spend paying for itself, and a short list of fixes they can make or ask their agency to make.
In short, the first customer to target is: Owners of local service businesses and small shops spending a few hundred to a few thousand dollars a month on Google Ads. Start with the narrowest version of this group you can reach directly, ideally in the same communities where the problem was posted, rather than trying to serve everyone with the problem at once.

Pricing guess
Estimate: free audit and calculator; $29-49/month for a guided monthly review; one-off $99-199 setup fix delivered by a vetted freelancer. This is our estimate, not market data: treat it as a starting hypothesis and test it with real buyers before relying on it. Price anchors from the alternatives below and what people already spend on workarounds are the best reality check.
MVP you can build
Weekend: a questionnaire covering what the business counts as a conversion, how calls and forms are tracked and how many leads closed last month, plus a calculator for spend, leads, close rate and average sale value. Output: cost per real customer, return on ad spend, a red/amber/green tracking checklist and a list of plain questions to ask an agency. Later, add read-only Google Ads API reports. Keep the first version deliberately small: the goal is to learn whether people use it and pay, not to build every feature.
How to validate it in three steps
- Publish a guide on telling whether Google Ads are working for a small business with the calculator embedded and track completions.
- Offer free audits to ten owners from local business groups and record how many discover broken or misleading conversion tracking.
- Test the monthly review offer with owners whose audit shows a tracking gap and measure conversion to paid.
Decide your success threshold before you start each step (for example, a number of signups or pre-orders), so the result actually tells you something.
Competition & existing alternatives

Risks
- Owners may not know their close rate or average sale value, so the tool needs sensible prompts and ranges rather than precise answers.
- Moving into API access and account changes adds technical work and requires following Google's API policies carefully.
- Agencies and Google's own recommendations compete for the same attention, so the product must stay neutral and explain results without jargon.
How we scored it
Opportunity score (6/10) rates how well the idea suits one founder building with AI or no-code tools: demand (30%, from the signal score), pain and willingness to pay (25%), buildable with AI or no-code (25%), easy first customers (10%) and room in the market (10%), each rated 0–10 and combined into a whole number. Signal score (2/10) is calculated from our data only: 2 points for one thread, 4 for two, 6 for three or more; +1 for each extra day the problem appears (max +2); and +2 if it ranked in the daily top 10, +1 for top 25, +0.5 for top 50. Neither score is a forecast. See our scoring methodology and how it works.
