Where do good product ideas come from?
Direct Answer
Good product ideas are usually found in other people's complaints and behaviour, not in a blank notebook. The richest free sources are Amazon 1-3 star reviews (complaints equal unmet needs), Reddit 'wish there was a' threads, Google Trends (the demand curve over time), competitor Q&A sections, and rising-product lists like AliExpress hot products and Amazon Movers & Shakers. Amazon Movers & Shakers refreshes hourly and shows the top 100 products with the fastest 24-hour sales-rank jump - a live trend scanner. RND SOURCING's sourcing desk watches these feeds every day and turns the patterns into shortlists for clients.
Detailed Explanation: Mine, Don't Invent
A blank page produces opinions; other people's behaviour produces evidence. The best founders are collectors, not inventors.
- Amazon 1-3 star reviews Complaints are a public list of what the category fails to deliver. 2-star reviews are the richest - buyers admit value but name the flaw.
- Reddit 'wish' threads Phrases like 'wish there was a' are unmet-need confessions waiting to be built.
- Google Trends Separates a dying fad from a rising demand curve before you commit.
- Competitor Q&A plus rising lists Q&A shows objections; Movers & Shakers and AliExpress hot products show what is climbing now.
Real-World Example: The Short-Claw Grooming Glove
RND SOURCING's desk noticed the same 2-star complaint across three Amazon leaders in pet grooming gloves: 'claws too short, fur slips through'. The flaw was common and unaddressed.
RND SOURCING wrote a spec for a short-claw variant, sourced a Yiwu workshop, and the client launched it against the incumbents. Google Trends showed steady category growth, not a spike.
Key Data: Where the Signal Lives
Behavioural data beats opinion data - and most of it is free and public.
PowerReviews (2023) found 96% of online shoppers specifically seek out negative reviews when researching; Amazon Movers & Shakers is updated frequently and lists the biggest 24-hour sales-rank gainers.
Step-by-Step: A Weekly Mining Routine
Fifteen minutes a day beats a panic weekend. Build a repeatable habit.
Pull 1-3 star reviews
In your target category, read the low-star reviews of the top three sellers. List repeated complaints.
Search Reddit and Quora
Find 'wish there was' and 'why is there no' threads in your niche. Note the recurring asks.
Check Google Trends
Plot the category keyword for five years. Rising and steady beats a one-week spike.
Scan Movers & Shakers
See which products jumped rank in 24 hours and why - season, viral video, or price.
Cross-reference AliExpress
Confirm the rising item also shows supply-side heat on AliExpress hot products.
Common Mistakes in Idea Sourcing
The traps that turn mining into noise.
- Copying the best seller The leader already owns that exact product. Mine its complaints; build the fix, not the clone.
- Chasing a one-week spike A Google Trends blip is a fad. You will arrive after demand already peaked.
- Ignoring the complaint pattern One angry review is noise; the same flaw across three leaders is a market gap.
- Mining without a niche 'Fitness' is too broad. 'Door-mounted resistance training for renters' is mineable.
