5 Overlooked Ways to Analyse Your Competition on Online Marketplaces

Selling successfully on online marketplaces like Amazon or Takealot is rarely about simply listing a good product and hoping for the best. The reality is that marketplaces are intensely competitive ecosystems where dozens—sometimes hundreds—of sellers are competing for the same customer.

Many brands focus only on obvious metrics like price or star ratings when analysing their competitors. While those factors matter, they rarely tell the full story. The brands that consistently win on marketplaces are the ones that dig deeper and analyse the competitive landscape more intelligently.

Here are five often-overlooked areas that can reveal powerful opportunities for your brand.

1. Study the Weaknesses Hidden in Competitor Reviews

Customer reviews are one of the most valuable sources of competitive intelligence on any marketplace.

Instead of simply looking at the average rating, read the negative reviews carefully. Recurring complaints often reveal product flaws, missing features, or customer frustrations that your brand can solve. For example, if customers consistently complain about poor durability, confusing instructions, or sizing issues, you can design your product or listing to directly address those gaps.

In many cases, your biggest product advantage is already being written in your competitors’ reviews.

2. Analyse Listing Quality, Not Just the Product

Many sellers underestimate how much listing quality affects performance on marketplaces.

When reviewing competitor listings, look closely at elements such as:

• Image quality and infographics

• Lifestyle photography

• Product titles and keywords

• Bullet point structure

• Enhanced brand content or A+ pages

Better images, clearer messaging, and stronger benefits can significantly increase click-through and conversion rates. Even if competitors sell a similar product, superior listing optimisation can give your brand a meaningful edge.

Often the opportunity is not in a better product—but in a better presentation.

3. Track Sales Velocity Using Marketplace Signals

Marketplaces rarely reveal exact sales numbers, but they leave behind clues.

One of the most useful indicators is ranking metrics like Best Seller Rank, which reflect how quickly products are selling relative to others in the category.

Tracking these signals across your top competitors can help you estimate:

• Which brands truly dominate the category

• How big the market opportunity is

• Whether demand is growing or declining

This type of analysis helps you avoid entering overcrowded markets or underestimating demand.

4. Watch Competitor Inventory and Stockouts

One of the most overlooked opportunities on marketplaces comes from inventory gaps.

If a leading competitor frequently runs out of stock, the marketplace algorithm often shifts visibility toward the next best-performing listings. This can create temporary but highly valuable windows for your brand to gain sales and ranking momentum.

Tracking competitor restocking behaviour also reveals how quickly products sell and how well competitors manage their supply chains.

5. Reverse Engineer Their Keyword Strategy

Search visibility is the lifeblood of marketplace success.

Rather than guessing which keywords to focus on, examine the keywords your competitors are already ranking for. Reverse ASIN tools enable sellers to pinpoint the specific search terms that direct traffic to rival listings (Refer to our follow-up Blog Article: "Reverse ASIN Analysis: A Keyword Strategy Shortcut").

This analysis can uncover:

• High-volume keywords you’re missing

• Niche search terms with low competition

• Content gaps in your own listings

In many cases, small improvements in keyword coverage can dramatically increase organic traffic.

The Bigger Lesson: Competitive Insight Creates Competitive Advantage

Marketplace success is rarely accidental. It comes from understanding the competitive landscape better than everyone else. By analysing competitor reviews, listing quality, sales signals, inventory behaviour, and keyword strategy, brands can uncover opportunities that many sellers completely overlook.

At Marketplace Executive, we believe that data-driven competitor analysis is one of the most powerful tools a brand can use to grow on marketplaces like Amazon and Takealot. The brands that win are not always the cheapest—but they are almost always the most informed.

And in the world of marketplaces, information is your greatest advantage.
