One of the hardest questions in ecommerce is: what should I sell next?
Most sellers answer that question with a keyword tool. They sort by search volume, find something with decent numbers and manageable competition, and launch. Then they wonder why it didn’t work.
Here’s the problem: search volume is not demand. It’s a data point that tells you how many people typed something into a search bar — not whether your product will actually sell, convert, rank, or turn a profit.
High search volume usually means high competition, high ad costs, and razor-thin margins. And if you ever want to sell off Amazon — on TikTok Shop, Shopify, through email — keyword search volume may be completely irrelevant.
The better question isn’t ‘what product has the highest search volume?’ The better question is: what product has real demand and real room to win?
Here’s how to answer that.
Demand Signal #1: Start With the Product Itself
Before you open a keyword tool, ask a more fundamental question: how good is this product, really?
The best products don’t just perform well in search results — they work everywhere. They work on Amazon, on Shopify, on TikTok, and through email marketing. They’re easy to explain, they solve a real problem, and people talk about them.
Questions to ask about the product:
- How significant is the problem this product solves? Is it a minor inconvenience or a genuine pain point?
- Can you explain what it does and why it’s better in one sentence?
- Would a customer tell a friend about it? Would they post about it?
- Does it work as an impulse buy, a considered purchase, or both?
- Could it generate repeat purchases or build brand loyalty?
Apple didn’t validate the iPhone with keyword data. There was no search volume to measure because nothing like it existed. The demand was created by the product itself. That doesn’t mean you should invent blindly — but it does mean strong product instincts should lead, and data should follow.
🔑 Key Takeaway
Search data should confirm a strong product idea — not be the sole reason you pursue it. If the product isn’t genuinely good, no keyword strategy will save it.
Demand Signal #2: Read the Competition Correctly
Most sellers look at competition the wrong way. They count listings. They look at review counts. They check BSR and assume the bigger the numbers, the harder it is to compete.
That’s surface-level analysis. Here’s what to actually look for.
What to look for in competitor listings:
- Content quality — are listings weak, generic, or outdated? Weak content is an opportunity.
- Review themes — what complaints come up repeatedly? Repeated complaints are unmet demand.
- Visual differentiation — do all the products look the same? Same-looking products = opportunity to stand out.
- Price clustering — are competitors all priced within a narrow band? That might mean room above or below.
Weak competition is often a better signal than high search volume. If you find a category where demand clearly exists but no one has nailed the product or the presentation, that’s your opening.
Conversely, if a keyword is dominated by brands with thousands of reviews, aggressive pricing, and massive ad budgets, organic ranking may be nearly impossible. You can run ads — but many sellers discover too late that every sale is a loss. That’s buying revenue, not building a business.
🔑 Key Takeaway
Count the quality of competition, not just the quantity. A category with weak competitors and clear customer complaints is more valuable than a category with high volume and well-funded incumbents.
Demand Signal #3: Use Amazon Data — But Use It Carefully
Keyword data absolutely belongs in your research process. It just shouldn’t be the only input — and it definitely shouldn’t be the first one.
How to use Amazon data the right way:
- Use search volume to confirm demand, not to discover it
- Look at keyword trends over time — is demand growing, plateauing, or declining?
- Check CPCs and sponsored product density — high ad costs signal a margin-unfriendly category
- Look at conversion rates of top competitors — if they’re low, the category may have a trust or clarity problem
- Use search volume as a lagging indicator: by the time volume spikes, competition is often already brutal
Think of keyword data as the last checkpoint before launch — not the starting point. If your product idea checks the other boxes (great product, weak competition, strong social signals), keyword data should confirm it. If the numbers don’t support the idea at that stage, take that seriously.
🔑 Key Takeaway
Search volume is a lagging indicator. High volume often means you’re late to the party. Use it to validate, not to lead.
Demand Signal #4: Use TikTok as a Demand Discovery Tool
TikTok is one of the most underutilized product research tools available to ecommerce sellers right now — and most people treat it as just a marketing channel.
It’s actually a real-time window into what people find interesting, shareable, and worth talking about. And it often shows demand before keyword tools catch up.
What to look for on TikTok:
- Repeated content around the same product type — multiple creators covering the same product independently
- Creators posting without affiliate links — organic enthusiasm is the strongest signal
- High saves and shares (not just views or likes) — saves indicate intent
- Comment sections full of “where do I get this?” — pure demand
- Low seller saturation — if only a few sellers are on TikTok Shop, margins may still be healthy
Contrast that with: dozens of TikTok Shop sellers already flooding the product with heavy discounts. That signals margin compression and a commoditized market — avoid it.
TikTok also gives you a sense of how explainable a product is. If creators can make compelling organic content about it naturally, your own marketing will be easier and cheaper.
🔑 Key Takeaway
TikTok shows demand earlier than keyword tools. High organic engagement with low seller saturation is one of the strongest early demand signals available right now.
Demand Signal #5: Check Off-Amazon Viability
If a product only works because of Amazon search behavior, it’s a riskier business than one that can sell anywhere.
Business buyers — aggregators, PE firms, strategic acquirers — pay higher multiples for brands with diversified revenue, repeat purchase behavior, and brand recognition outside of Amazon. If your entire business depends on Amazon search rankings, that’s a liability, not an asset.
How to evaluate off-Amazon viability:
- Google the product and look at Shopify and DTC brands selling it — how long have they been around?
- Check their pricing, bundles, and subscriptions — are customers paying premium prices willingly?
- Look at their social presence — is there an engaged community around this product?
- Check if the product appears in editorial content, gift guides, or press coverage
- Ask: could this product be sold through email to an existing list? If yes, the demand is platform-independent.
Products that have legs off Amazon are worth more, scale better, and build more durable brands.
🔑 Key Takeaway
Off-Amazon demand is a multiplier on brand value. If a product can only sell through Amazon search, build that into your risk assessment before you launch.
Demand Signal #6: Watch Customer Behavior — Hacks, Complaints, and Workarounds
This is one of the most overlooked demand signals, and it’s hiding in plain sight.
When customers modify a product, hack it, or build DIY workarounds to get what they actually want — that is demand. When the same complaint appears in hundreds of reviews across multiple competitors — that is opportunity.
Where to find these signals:
- Amazon reviews — filter 3-star reviews for the most actionable feedback
- Reddit threads — look for subreddits where your target customer hangs out
- Facebook groups — product communities often surface unmet needs explicitly
- YouTube comment sections — people explain what they wish the product did differently
- TikTok comments — raw, unfiltered customer reactions
If customers are consistently asking for a version of a product that doesn’t exist yet — or modifying an existing one to get there — you don’t need keyword data to validate demand. The customers already told you.
🔑 Key Takeaway
Customer complaints and workarounds are demand in disguise. The product that solves the problem everyone is complaining about has a built-in audience before it even launches.
Bonus: Think About Timing — Not Just Current Demand
Not every product needs massive demand right now. Some of the best product opportunities are the ones where demand is growing but hasn’t peaked yet.
By the time search volume spikes on a product, competition is often already intense. Early movers who spotted the trend on social platforms — before the keyword tools caught up — built dominant positions without the ad budget wars.
How to spot early-stage demand:
- Low but growing search volume with increasing trend line
- Strong TikTok engagement with relatively few Amazon sellers
- A product solving a problem that is growing in relevance (health trends, remote work, sustainability)
- A category where DTC brands are starting to get press but Amazon is still underdeveloped
Think of search volume as a lagging indicator. Social platforms are leading indicators. Get there early, build reviews and rank, and by the time everyone else catches up — you already own the category.
The Full Product Evaluation Framework
Here’s the complete process, in order:
- Step 1: Evaluate product strength — Is it genuinely good? Easy to explain? Shareable?
- Step 2: Read competition quality — Weak content? Repeated complaints? Lack of differentiation?
- Step 3: Confirm with Amazon search volume — Validate, don’t lead with it
- Step 4: Pressure test with TikTok — Organic content? High saves? Low seller saturation?
- Step 5: Assess off-Amazon viability — Does it sell on Shopify? Is there brand loyalty?
- Step 6: Forecast conservatively — What will traffic cost? How hard is it to explain? Does it fit your lineup?
Run every product idea through this framework before you commit. It won’t eliminate risk entirely, but it will dramatically improve your launch success rate and help you avoid the traps most sellers fall into.
