The most useful Amazon product research metric is the sales to review ratio, which tells you how much revenue a market generates relative to the review count you need to compete in it. Casey Gauss looks for markets where the top sellers average a ratio of two to three or better, meaning reviews are a low barrier to entry.
Casey founded Viral Launch, which builds Amazon seller software and has run roughly 30,000 product launches across more than 7,000 brands. His clients range from sellers with $2,000 monthly budgets to a private label operation doing over $100 million a year.
This episode covers his go wide strategy of selling many modest products instead of a few large ones, the listing optimization rules most sellers get wrong, and how to calculate the sales velocity needed to reach a specific page-one position.
An important note on the launch mechanics discussed here. Two-step URLs and deeply discounted giveaway campaigns intended to manipulate keyword ranking now violate Amazon’s terms of service and risk account suspension. Those sections are included because the underlying velocity logic still explains how ranking works, and the specific tactics should not be used today.

Key takeaways
- Prefer ten products doing $10,000 a month over one doing $100,000, because low-competition markets need far less defending.
- Use the sales to review ratio to find those markets. Divide estimated monthly sales by review count and look for two to three or higher.
- Ignore outliers when evaluating a market, since a single seller with huge volume may be driving external traffic you cannot replicate.
- Include both singular and plural forms of your keyword in the title. Amazon treats them as separate search terms.
- Leave your brand name out of the title. Amazon displays it separately and it wastes character count.
- Place a colon or hyphen after the fifth title word to control your canonical URL, which affects Google SEO.
- Enhanced brand content ranks very low in priority. Keep your Seller Central description filled in regardless, because those words still index.
- Photos drive conversion more than copy, since shoppers want their questions answered visually rather than by reading.
What is the go wide strategy for selling on Amazon?
The go wide strategy targets many products doing $10,000 to $30,000 a month in low-competition markets rather than a few products doing six figures. Casey’s phrasing is that he would far rather sell ten products at $10,000 a month than one at $100,000.
Competition is the reason. Six-figure markets demand continuous effort to hold your rank and constant vigilance against competitors using shady tactics against your listing.
Low-competition markets need almost none of that. You get in, rank, reach the market’s sales ceiling, and move to the next product.
Risk distribution is the other benefit. Losing a $100,000 product out of $250,000 in monthly sales is devastating, while losing three products out of a hundred doing $10,000 each barely registers.
The strategy scales through process. Once you have built a repeatable launch process, you push new products through it, and low-competition markets make each pass straightforward.
Should go wide products be related to each other?
It depends entirely on whether you want a sellable brand or pure cash flow. Cohesion across the product line matters if you intend to sell the business or build off-Amazon.
If cash flow is the goal, the products can be completely unrelated. Casey knows an account doing over $30 million a year selling pet products, health products, car accessories, and essentially everything else.
That operation’s skill is market selection rather than brand building. They identify low-competition markets, enter quickly, and perform well.
What is the sales to review ratio and how do you use it?
Divide a product’s estimated monthly sales by its review count. A product selling 1,000 units a month with 100 reviews has a ratio of 10, and one selling 1,000 units with 1,000 reviews has a ratio of 1.
Higher ratios mean a better return on the work required to compete. Casey looks for markets where the top ten average two to three or above, and considers ten or higher excellent.
The logic behind treating reviews as the barrier to entry is consumer behavior. Review quantity is the only popularity signal shoppers actually see, so a product with 1,000 reviews next to competitors with 10,000 reads as inferior even though 1,000 is objectively a lot.
Evaluate the market rather than individual listings. A single low-review seller with high volume tells you nothing you can act on.
Why should you ignore outliers in Amazon market research?
A single seller vastly outperforming the market may be driving external traffic you cannot replicate. If the top ten sellers do 1,000 units a month and one does 10,000, that outlier is running something you cannot see.
The reasonable assumption is that most sellers are not driving significant external volume. So the market average tells you what is achievable from Amazon search alone.
Basing your entry decision on the outlier is the mistake Casey sees most often. People find one low-review listing with high sales and conclude they can copy it.
How should you optimize an Amazon product title?
Include singular and plural forms of your main keyword, keyword-stuff rather than writing prose, and leave your brand name out. Casey considers listing optimization one of the most underrated factors in Amazon success.
The plural rule has a concrete example behind it. A client selling grill gloves had only the plural in his title, so a promotion targeting the singular “grill glove” reached mid page two while the plural sat in the top ten of page one.
Keyword stuffing beats elegance because sessions compound. Ranking for two or three times as many keywords with a lower click-through rate still delivers more total traffic.
Brand names in titles waste characters. Amazon displays your brand separately in most search results, and nobody searches your brand unless you are already a household name.
How do you control your Amazon canonical URL?
Place a colon or hyphen after the fifth word of your title. The five words preceding that punctuation, excluding stop words like “and” and “the,” determine your canonical URL.
The benefit is on Google’s side rather than Amazon’s. Casey is uncertain whether it helps Amazon search and confident it helps how the listing ranks in Google.
Does enhanced brand content improve conversions?
Enhanced brand content ranks insanely low in Casey’s priority list, with measured impact ranging from none to slight. Split testing it is difficult because changing a listing disrupts search ranking, which contaminates the results.
One tactical point is worth acting on. If you use enhanced brand content, keep the standard Seller Central description filled in, because those words still index and contribute to ranking.
Photography drives conversion far more than any content module. Images should answer how many pieces are included, what you get and do not get, and how large the item is, because shoppers increasingly want to confirm and buy without reading.
Which keyword should you target when launching?
Target the highest-volume keyword rather than a long tail variant, because sellers ranking for the main term also receive ranking power for the long tail. Competing on long tail keywords against them is not sustainable.
If you sell fish oil, target “fish oil” rather than “omega 3 supplements.” The high-volume sellers already have both phrases in their listings.
How do you find your target position on page one?
Look for a pocket of relatively low review counts among the page-one results and aim to rank inside it. If most listings have 1,000 reviews and three consecutive positions have 250, 175, and 100, that is where your 50 to 100 reviews look competitive.
Relative comparison is what shoppers actually do. Your review count is judged against the listings directly above and below you rather than in isolation.
How does Amazon sales velocity affect keyword ranking?
Amazon evaluates sales history in rolling buckets: 24 hours, 48 hours, three days, five days, seven days, and then in seven-day increments. Ranking depends on recent sales relative to competitors, which is why Casey’s launches historically targeted the seven-day bucket.
The calculation works backward from your target position. If the sellers you want to rank alongside move 900 units a month, that is 30 units per day you need to match.
More competitive markets require filling longer buckets. Very high volume markets meant targeting the 30-day window rather than seven days.
Keyword ranking movement lags sales by two to three days and can take five to ten. Casey’s observation is that impatient sellers kill campaigns after four days and conclude they do not work.
Importantly, the giveaway-based version of this approach violates current Amazon policy. The velocity mechanics still explain why sustained sales matter for ranking, and the legitimate levers are advertising and price rather than incentivized purchases.
Why lowering your price beats deep discount promotions
Lowering your listed price sustains the sales velocity that maintains ranking, and it does so through legitimate purchases that can generate reviews. Casey advocates for this over giveaway mechanics, and it is the approach that remains compliant today.
His framing is a comparison of costs. Giving product away at 90% off versus selling it at 40% off both cost margin, and only one produces reviewable purchases and durable ranking.
The results can be dramatic. He has seen sellers go from five organic units a day to 35 by cutting price, with ranking improvements following.
Sponsored ads work the same way. Running them aggressively during a launch adds real sales volume that feeds the ranking algorithm.
The pattern across successful launches is willingness to lose money early. Accepting near-breakeven economics during launch buys the ranking and review base that makes the product profitable afterward.
Why reviews are the currency of Amazon success
Reviews are the primary constraint on Amazon sales, and the only legitimate way to generate them is through actual sales volume. That is the core argument for driving sales through price and advertising rather than any other method.
Casey avoided review manipulation entirely at Viral Launch, treating it as the one behavior guaranteed to draw Amazon’s attention. With a 40-person company and thousands of clients, the risk was never worth it.
Amazon also blocks reviews on heavily discounted purchases for some products, which further undermines discount-driven approaches. Full-price and modestly discounted sales are the ones that produce reviews.
Package insert cards are the area Casey was most interested in exploring. He had not encountered anyone getting in trouble for them, though note that Amazon has since restricted what inserts may say about reviews.
How should you think about competitors using black hat tactics?
Casey’s position is never to use black hat tactics, particularly around reviews, because that is where he has consistently seen sellers taken down. The frustration is that honest sellers pay a price for others cheating.
Detection is genuinely hard for Amazon when manipulation is done carefully. That creates an incentive structure where cheating appears to work, which is exactly the problem.
The counterargument is durability. An account built on manipulated reviews is one enforcement wave from disappearing, which is a poor foundation for a business you want to own in five years.
How do Chinese sellers compete on Amazon?
Chinese sellers competing directly on Amazon were, at the time of this conversation, limited by marketing rather than by product or price. They compete on low prices and generally do not invest in photography, listing quality, or the willingness to lose money to gain ranking.
Casey’s warning is about what happens when that changes. Once manufacturers selling directly understand the full playbook, third-party sellers become middlemen with no advantage.
Large established brands have the opposite problem. Casey sat on regular strategy calls with major consumer brands who believed paid media was the only lever available on Amazon, and whose ad spend was outpacing their revenue growth badly enough that some concluded they had to stop.
That gap is the third-party seller’s actual advantage. Independent sellers stay on the cutting edge of what works in a way both giant brands and price-focused manufacturers currently do not.
Frequently asked questions
What is the sales to review ratio on Amazon?
Estimated monthly sales divided by review count. A ratio of two to three across a market’s top sellers signals low competition, and ten or higher is excellent.
Is it better to sell one big product or many small ones?
Many smaller products in low-competition markets require far less ongoing defense and spread your risk. Losing one product out of a hundred is survivable in a way that losing your only large product is not.
Should you include your brand name in your Amazon title?
No. Amazon displays your brand separately in search results, so including it wastes character count you could use for keywords.
Do you need singular and plural keywords in your title?
Yes. Amazon treats them as distinct search terms, and omitting one can cost you page-one ranking for that variation.
Does enhanced brand content help Amazon rankings?
Its measured impact ranges from none to slight. Keep your Seller Central description filled in even when using it, since those words still index.
How many sales per day do you need to rank on page one?
Match the daily sales of the listings you want to rank alongside. If they sell 900 units a month, that is roughly 30 units per day.
How long does Amazon keyword ranking take to update?
Typically two to three days, and sometimes five to ten. Judging a campaign after four days is premature.
Are giveaway launches still allowed on Amazon?
No. Incentivized giveaways and two-step URLs intended to manipulate ranking violate Amazon’s terms of service and risk suspension. Sponsored ads and price reductions are the compliant ways to build sales velocity.
