Picture a merchant with a narrow catalog and an empty spreadsheet. The store sells a handful of products in one niche, traffic is steady, and the obvious next move is to add more. The hard part is knowing what. Product lists online are no help, because they describe nobody’s store in particular. A better source of evidence is already sitting in a browser tab: the competing stores your customers visit before, after, and sometimes instead of yours.
Competitor research is not about copying. Every collection, price tier, bundle, and review on a competing Shopify store is a data point about what shoppers in your niche already expect to find. Put those data points side by side and a map appears. It shows where the category is crowded, where it is thin, and where a better or more relevant option could earn a place. This guide explains how to build that map, how to read it, and how to turn each gap into a small, low risk product test.
| Quick answer: Shopify competitor research is the process of studying competing stores, including their collections, bestsellers, price ranges, bundles, and customer reviews, to find products that shoppers in your niche already expect but your store does not yet offer. The output is not a copy of anyone’s catalog. It is a short list of product gaps, each one written as a hypothesis you can test. |
Shopify competitor analysis has a reputation for being a spying exercise, usually involving expensive tools and a hunt for one secret bestseller. In practice, the useful version is quieter and more systematic. You gather publicly visible information from several stores, record it in one place, compare it against your own catalog, and look for patterns that repeat. A pattern that shows up across independent stores is evidence. A single odd product on a single store is a curiosity.
This is also where ecommerce competitor research differs from general product research. Product research asks whether an idea can succeed in a market. Competitor research asks a narrower and more practical question: given the products that already exist in this niche, what is missing from my catalog? Shopify’s own guides treat the two as partners, with product research validating demand and competitive analysis showing where rivals leave openings. The work in this article sits at the point where they meet.
Start the way a customer would. Type your main product terms into Google, then add the word alternatives, and note which stores keep appearing. Check the marketplaces and social platforms where your audience shops. Shopify’s guide to competitive analysis, citing the US Chamber of Commerce, suggests a shortlist of no more than 10 direct competitors. For gap work, five to eight stores is usually enough, provided the group has some variety. Read the full Shopify competitive analysis guide for the wider framework.
A balanced set usually includes four types of store. One or two close matches show you what your direct rivals sell and how they price it. A larger category leader shows the full range of the niche, including subcategories you may not have considered. A fast growing newer store shows where demand is moving. One indirect competitor, which solves the same customer problem in a different way, shows you the substitutes your buyers weigh against your products. Studying only stores that look like yours tells you what you already know.
A competing store is a large pile of evidence, and most of it is noise unless you decide in advance what to collect. These are the elements worth recording, and what each one tells you.
The way competitor collections on Shopify stores are grouped shows how shoppers in your niche think about the category. If three stores each have a dedicated collection for a subcategory that your store folds into a general page, that subcategory probably earns its own space for a reason. Record the main menu labels, the collection names, and how many products sit in each. Navigation labels are especially valuable because stores tend to name them after the words customers use.
Bestsellers on Shopify stores are often easy to see. On many stores, adding /collections/all?sort_by=best-selling to the store address shows products ordered by how well they sell. You can also look for bestseller badges and curated bestseller collections. Treat this as rank, not volume. It tells you what sells relatively well within that store, not how many units moved, and some stores turn off or override sorting. Cross check the ranking with review counts and with whether the same product type appears among the bestsellers of several stores.
For each collection, note the lowest priced item, the highest priced item, and where most products cluster. Price clusters show you the price bands your niche accepts. A collection with products only at the low end and only at the high end, and nothing in between, is a signal worth writing down. So is a collection where every product sits at almost the same price, which suggests a category with little room for differentiation.
Look at product pages for sets, starter kits, and frequently bought together suggestions, and look at the cart for upsell offers and free shipping thresholds. Bundles tell you which products customers use together. Free shipping thresholds tell you the order value a competitor is trying to reach, which hints at their average order size and the accessory items they hope to add.
Product titles show the vocabulary a competitor believes customers search with. Photos show what proof shoppers need before buying. If every store in a niche shows a product next to a hand or a coin for scale, buyers worry about size. If every store includes an in use photo, buyers want to see the product doing its job. These details shape your own product pages later.
Reviews are the most direct evidence on the page, because customers write them without being asked. Read the praise, the complaints, and above all the sentences that begin with I wish or It would be better if. Those sentences describe needs the product did not meet, and a need that one store did not meet may be a need that your store can.
The filter options on a collection page list the attributes shoppers use to narrow their choice, such as size, material, scent, color, or compatibility. A filter that appears on several stores is a decision factor. A filter that appears on none, but that customers mention in reviews, may be an unaddressed need.
Not everything you see on a competing store reflects what customers want. Some of it only reflects what a designer liked. The distinction matters, because copying a design choice wastes effort while ignoring a demand signal wastes opportunity. A simple test helps: if the same observation appears on several unrelated stores, it is more likely to reflect shopper behavior. If it appears on one store only, it is more likely a choice or an experiment.
How to read what you see on competitor stores
| What you see | Reads as | Why |
| The same product type ranks among bestsellers on several stores | Demand signal | Independent stores reaching the same result is hard to explain by coincidence |
| Several stores give one subcategory its own collection and menu label | Demand signal | Stores give prominent space to what earns it |
| Reviews repeat the same request or complaint | Demand signal | Customers are stating an unmet need in their own words |
| A bundle appears on more than one store | Demand signal | Bundles tend to survive where products are used together |
| A unique product appears on one store only | Weak signal | It could be a supplier deal, a test, or a leftover item |
| Layouts, fonts, banners, badge styles | Design choice | These shape how a store looks, not what customers want to buy |
Date every observation you record. Product ranges, prices, and bestseller rankings change, and a note without a date is hard to trust later.
Product gap analysis is the step that turns observations into decisions. It starts with a spreadsheet. Give every competitor a column and every subcategory a row, and record for each cell how many products the store offers, the price range, whether any product is a bestseller, and whether a bundle exists. Add your own store as the first column. This is a product assortment analysis, and it shows at a glance where your catalog is deep, where it is thin, and where it is empty.
Keep what you observed separate from what you conclude. Shopify’s guidance on competitive research makes the same point: record the evidence and when you found it, and keep your interpretation in separate columns. It also warns that an empty space on a market map does not prove customers want something there. Validate a gap before you act on it. Google Trends helps with that check. It shows whether search interest in a product type is stable, growing, seasonal, or fading, which matters because Shopify’s product research guidance separates fads, trends, stable categories, and growing categories.
Gaps are easier to act on when you name their type, because each type points to a different test. The five below cover most of what a competitor review turns up. The examples assume a hypothetical store that sells kitchen organization products, and they are illustrations of the method, not findings.
Five product gap types and how to test each one
| Gap type | What it looks like | Where to find the evidence | Example test |
| Problem gap | Customers describe a problem that no product in the category solves well | Reviews on competitor product pages, repeated complaints | Reviews say drawer organizers slide around, so test drawer grip liners |
| Price gap | Competitors cluster at the low end and the high end with nothing in between | Price ranges per collection in your spreadsheet | Spice racks sit in two clusters, so test one in the middle band |
| Routine gap | Competitors sell some steps of a customer routine but skip one | Navigation labels, bundles, review mentions of what else customers bought | Stores sell containers but nothing for labeling, so test label sets |
| Bundle gap | Products customers use together are only sold separately, or only as sets | Product pages, cart upsells, frequently bought together blocks | Containers are sold one by one, so test a starter set |
| Trust gap | The category lacks clear specifications, size guides, or comparisons | Product pages with missing dimensions, materials, or care details | Competitor pages omit dimensions, so test a product with a full size guide |
Notice that a trust gap is not always a missing product. Sometimes the opening is a clearer page, a better size guide, or a recognizable brand where the rest of the category sells anonymous items. For products with real brand recognition, shoppers need less persuasion, which is a quiet advantage in categories where trust is the main barrier.
Beyond the five types, a few places repay a second look. Missing subcategories show up when a competitor has a collection you do not have. Missing accessories show up in bundles and cart upsells. Missing entry level options show up when every product in a collection starts above a certain price. Missing premium options show up when everything sits at the same modest price. And products that customers keep mentioning in reviews, but that no store sells, are the clearest gaps of all.
The biggest risk in this exercise is mistaking presence for proof. A competitor can carry a product for many reasons that have nothing to do with your store: a supplier relationship, a loss leader that brings in traffic, a legacy item, a different customer base, or a product that simply does not sell and has never been removed. Before any product moves from the spreadsheet to your catalog, run it through five checks.
Does the product belong next to what you already sell, and would your existing customers recognize it as a natural addition? A good gap on paper can be the wrong fit for your brand.
Does the math still work after product cost, platform fees, shipping, and the advertising needed to bring buyers to the page? A competitor’s price tells you what the market accepts, not what your margin allows.
Can you deliver the product at the speed your store already promises? A product that ships slowly in a store known for fast delivery creates a mismatch that hurts reviews on every other product too.
Can you build a product page that is clearly better than the competitor’s, with accurate specifications, honest photography, and answers to the questions reviews raise? If the best you can do is match them, the gap is smaller than it looked.
Can you point to evidence, such as repeated reviews, search interest, or presence across several stores, that customers want this? If the only evidence is that one competitor sells it, keep looking.
Then test a small set first. Choose three to five gaps, not twenty. A small test is easier to read, easier to reverse, and far cheaper if the answer turns out to be no. It also guards against analysis paralysis, which Shopify’s own product research guide flags as the other side of due diligence. Decide in advance how long the research phase lasts, and stop when the time is up.
A gap becomes useful when it is written as a hypothesis. A good hypothesis names the product type, the price position, the place it will live in the store, the angle of the product page, and the result that would count as success. Use this template for each gap.
| We believe [customer group] will buy [product type] at [price position] when it is placed in [collection], because [evidence from research]. We will treat the test as a success if [metric] reaches [threshold] within [time period]. |
The success threshold should be relative to your own store, not a number borrowed from an industry article. For example, a new product earns a longer run if its add to cart rate matches or beats your store average, if shoppers ask questions that show real interest, and if the order value it adds is healthy. A product that gets views but no add to cart is telling you the page, the price, or the product is wrong. A product that gets few views is telling you about placement, not demand.
Example test plan for the kitchen organization illustration
| Gap tested | Product to test | Price position | Where it goes | Success metric |
| Routine gap | Label sets | Low, as an add on | Pantry collection and cart upsell | Add to cart rate at or above store average |
| Bundle gap | Starter container set | Slightly below the combined price of the parts | Top of pantry collection | Orders and average order value |
| Price gap | Mid band spice rack | Between the two competitor price clusters | Spice and herb collection | Conversion rate compared with neighboring products |
| Problem gap | Drawer grip liners | Low to mid | Drawer organizers collection | Add to cart rate, plus questions received |
Prioritize the low risk tests first. Accessories and entry level products are cheap to try and quick to judge. Premium products and large bundles carry more risk and should wait until the early tests have taught you something about your buyers. Run each test long enough to collect a meaningful amount of traffic, and compare results across the whole set before deciding where to expand.
Research ends with a list of gaps. The next obstacle is practical, because testing a product normally means buying it first. A bulk order for an untested idea is the kind of commitment that makes merchants hesitate, and hesitation is why many good gaps never get tested.
Mysellerhub is a Shopify app built for this stage. It connects your store to a catalog of branded U.S. products already stored in Amazon fulfillment centers, currently more than 10,000 products. You list a product without buying it and without a minimum order. When a customer orders, Amazon ships the item directly to them, usually within 1 to 3 days, and you pay the product cost only at that point. Mysellerhub states that margins in its catalog start at 40 percent, and the app is free to install.
The connection to gap analysis is direct. A price gap becomes a search for an entry level or premium alternative in the same subcategory. A bundle gap becomes a search for products that pair with an existing bestseller. A routine gap becomes a search for the missing step. Custom pricing rules let you place the price inside the band your research identified, and stock sync keeps the listing accurate if an item runs out, so a test does not turn into a customer service problem.
One honest caveat applies. The catalog will not hold a match for every gap you find. When it does not, that is useful information too, and a reason to consider a different sourcing route for that product rather than forcing a poor match into your store.
Twenty competitors produce twenty times the notes and very little extra insight. Patterns appear after five or six stores, and beyond that you mostly collect exceptions.
Stores that resemble yours show you the same assortment you already have. Add a category leader and one indirect competitor to see the edges of the niche.
Rank shows relative position inside a store. A store with few orders can have a bestseller that sells a handful of units a month. Confirm with review counts and with repetition across stores.
A competitor’s price reflects their costs, their brand, and their traffic. Use price ranges to find bands and gaps, then set your own price from your own margin.
Reviews are free customer research. Skipping them means skipping the clearest statement of what the category fails to deliver.
Catalogs, prices, and rankings change. Record the date on every observation and repeat the exercise on a schedule that matches how fast your niche moves.
Studying publicly visible pages is normal practice. Copying a competitor’s photos, descriptions, or branding is a different matter. It can create legal problems and erodes the trust that makes a store worth visiting.
It is the process of studying competing Shopify stores to learn what products, prices, bundles, and page content shoppers in a niche already expect, so you can find products your own store is missing.
On many Shopify stores, adding /collections/all?sort_by=best-selling to the store address sorts the products by sales performance. You can also look for bestseller badges, curated bestseller collections, and review counts. Remember that this shows rank, not unit sales, and that some stores restrict sorting.
A product gap analysis compares your catalog against the assortment of competing stores to find subcategories, price bands, accessories, bundles, or content that customers want and your store does not provide.
Five to eight is enough for most stores. Shopify’s competitive analysis guide, citing the US Chamber of Commerce, suggests keeping a shortlist of no more than 10 direct competitors. Variety matters more than quantity.
Match the schedule to your niche. A stable category may need a full review a couple of times a year, with a quick check before each season. A fast moving category benefits from a lighter monthly check. Whatever you choose, date your notes so you can see what changed.
Free tools cover most of the work. Google Trends shows search interest over time. The Meta Ad Library and Google Ads Transparency Center show the ads competitors are running. Your own Shopify analytics show how your products perform once you test them. Paid tools can add traffic estimates, but they are optional.
List the product without owning it and watch how shoppers respond. A sourcing app that lets you add products with no purchase and no minimum order, such as Mysellerhub, lets you collect real add to cart and conversion data before you commit any money to stock.
Competitor research is only worth the time it takes if it ends in a decision. Review your spreadsheet, pick the three to five gaps with the strongest evidence and the lowest risk, write each as a hypothesis, and decide how you will measure it. The research gives you the map. The tests tell you which roads are worth building.
Use your competitor research to choose a few product gaps, then test matching products through Mysellerhub. It is free to install, with no subscription and no setup fee, and you pay the product cost only when an order comes in. You can also find the app on the Shopify App Store.
