Whether your dream is to open up a brand-new eBay store or just push your existing store to the next level, the key to success is eBay product research.

Lots of people dive in head first without putting an ounce of consideration into their target market, their product quality or their pricing strategy. And sadly, these people are usually left disappointed by the results.

So, let’s take a look into the correct ways to conduct eBay product research to help you build your eBay empire.

How to find trending products on eBay

Finding the best trending products on eBay is essential to help you stay ahead of your competition and maximise your potential sales conversion.

eBay trending items are products that may not necessarily be something in your specific niche. However, they are items that you can be confident will sell well based on the most up to date statistics.

Keep in mind that trends don’t last for very long - that’s why they’re trends. These are the items that you can sell in high volumes temporarily to make a huge profit. But don’t get too attached. What’s hot this week may not be next week.

Ways to identify trending items on eBay

Use eBay’s trending deals & best sellers

There’s always the ‘Trending on eBay’ section. This shows sellers exactly what’s popular right now, giving you insights into eBay trending items and best sellers. But make sure you consider the time it takes to stock the item. If you stock physical items, remember to account for the extra time before it gets to your customers. Trends don’t last forever.

Monitor eBay’s search trends

Auto-suggestions are an excellent way to understand the current market. Typing a keyword into the eBay search bar will automatically suggest products that customers have searched before.

Of course, you can’t guarantee how many people have searched for that item or how recently. But it definitely gives you a basic idea to work with.

Social media trending research

One of the best ways to see what’s up-and-coming in your market is to cast your eye over social media. TikTok or Instagram will advertise various products that are just built to ‘trend’. These products may naturally appear on your feeds and show items that are about to go viral.

Check competitor listings

Competitor monitoring is a reliable way to track your own success. If you see your competitors doing well with a certain product, then perhaps you should be selling the same.

How to identify high-demand items on eBay

The best-selling items on eBay aren’t necessarily those that are trending. The first thing you need to identify is your niche area. Do you intend to sell gardening products or collector’s items? These things may not be trending, but they can still be popular year-round.

While certain items in your eBay store may be added based on the current market trends, others might be in consistently eBay high-demand products, or even seasonal items that you should be offering to your customers at the same time each year.

Follow seasonal and event-based demand

Certain products will do well in the summer months, but may fall down in the winter, or vice versa. For example, Christmas decorations, or garden furniture.

The trick here is to plan ahead. Grab the data from the previous few months, or even the previous year and see which eBay sales trends typically work well. Using reliable data to highlight eBay high-demand products, for each month based on your competitor’s stores, or even your own from previous years, will help you to create a solid base of core products that you know will work time and time again.

These types of products are also great for your profit margins, as they’re less likely to be left in your inventory year after year.

The best tools for eBay product research

While many sellers rely on guesswork to build their eBay stores, it’s much more effective to base your buys on actual eBay market research tools and raw sales data.

There are a ton of services out there that can make predictions or suggest eBay seller strategies using data. But the best solution is to grab the raw data from your competitors and see the full picture.

The main benefit of raw data is that you can keep revisiting the stats to understand how you can make changes long-term, without relying on a single strategy that may not pan out. Grab the data on sales volumes, average selling price and sold listings of your competitors and identify those eBay high-demand products that make frequent sales.

You can also identify price fluctuations so that you can deliver a winning pricing strategy, where both you and your customers see a benefit. You’ll conduct an eBay competitive analysis and identify areas of low competition that may present you with an opportunity to sell.

Filtering your data by performance, category, pricing or seasonal uplifts can help you visualise your new sales direction and direct you to popular listings so you can tailor your descriptions to your target audience.

Why raw eBay data really matters

  1. Raw data helps you to select products based on real demand, rather than just basing your purchases on guesswork or assumptions.
  2. It can help you to maximise profits by creating a pricing strategy that works - giving you the edge to undercut your competitors, but still make a sizable profit.
  3. Data gives you the full picture to help identify trends and seasonal products so you can prepare your inventory ahead of time.
