No single signal proves demand absolutely. Search volume indicates interest, a conversation reveals a question and a payment shows a decision under a particular offer. Combine signals and test a clear hypothesis before expanding inventory or advertising.
Define the hypothesis before collecting numbers
Specify the customer, need, product, price and acquisition channel. A hypothetical example is a lightweight laptop bag for daily commuters. “Everyone needs it” is not a testable segment.
Separate demand limitations from execution problems. Checkout can fail because of delivery cost or unclear sizing rather than lack of demand. Test the need, offer and buying process independently.
Collect signals across different stages
Use Keyword Planner with the appropriate location, language and period, then interpret intent rather than volume alone. Learning how to make an item differs from searching for its price or a seller. Review recurring customer questions and accessible feedback.
Test a real offer the business can fulfill. Staff, friends and test purchases should not be treated as independent market evidence. Record each signal’s source and date so comparisons remain meaningful.
Seven signals and their limits
Scroll the table horizontally to see all columns.
| Signal | What it reveals | What it does not prove alone |
|---|---|---|
| Purchase-intent searches | Interest in a solution | Your future sales volume |
| Repeated question | Need or objection | Willingness to pay |
| Alternative comparisons | Decision criteria | Preference for your item |
| Cart addition | Interest in the offer | Completed payment |
| Paid order | An actual purchase decision | Profitability |
| Delivered order without return | Initial fit | Future repeat purchase |
| Returning suitable customer | Potential recurring value | Guaranteed growth |
Set boundaries for the test
Define products, channel, duration, spending limit and conditions for pausing or reviewing the test. Start with a small offer rather than changing several discounts and channels at once.
Follow confirmed orders through delivery and returns rather than counting only purchase-button clicks. Early results may simply be insufficient. That is more defensible than projecting a month of sales from two orders.
Choose a reversible next step
Interest without purchases calls for review of price, information and delivery. Purchases without repeats require understanding product experience and the natural buying cycle; not every item is repurchased monthly.
Use a limited catalog and tested order flow in Mollkom, expanding quantities or channels when evidence supports it. AI can help prepare the test materials, but it does not replace feedback from real customers.
Common questions
Is keyword volume enough to choose a product?
It is an input, not a sales forecast. Combine intent with the ability to offer and fulfill the product.
When should the test stop?
At the predefined limit or when a fault or clear mismatch appears. Mark small samples as inconclusive rather than forcing a verdict.
Your next step
Continue with ecommerce marketing, or register and start your store. Apply the process to a small sample before expanding.
