If you notice that your product sales are a little low or simply want to try and boost your sales higher than they previously have been, there are a number of different things you can do to improve your item's list position.
Check out your competitors - Lets say the item you're looking to sell is a clothing item. Check out stores which sell items similar to you and see how much they sell these types of items for. If you see that other store owners are selling the item for £30, place it in your store for £25. Generally users list their search results based on cheapest first. So if your product is lower in price than your competitors, it is going to appear higher up the ranking and be more appealing to buyers. However, before lowering the price of an item, you should factor in eBay and Paypal fees to ensure you are still making a profit on the product.
Use more keywords - When placing your item for listing, ensure that the title of the item has the keywords in it that buyers generally search for. There is no point selling a product but having a vague title that only loosely relates to the product your selling. This will result in it appearing way down the list on most search results.
Become a top seller - High sales figures and a high positive feedback score will result in you achieving top seller status for your account. One of the immediate positives is that your listed products will instantly appear higher in search results. Not only will they appear higher, but the top seller tag will also make you appear more trusting to potential buyers, meaning your items will receive a lot more views and hopefully sales.
Correct categorisation - One of the more obvious solutions is to check that you have listed your item in the correct category. One of the more common mistakes that people make is listing a product accidentally in a category that has nothing to do with the product. This means that when a buyer searchers for items in a specific category, your item will not show up on these results.
If you implement any of these into your products, you will instantly see a change in your product's ranking within eBay search results.
