Common eCommerce Listing Mistakes

Grouped by what they actually cost you.

Mistakes that cost visibility

Blank item specifics. The biggest and most common. Filtered browsing depends entirely on them, and an empty specific removes you from that filter regardless of your title.

Wrong category. Invisible to everyone browsing the right one.

Marketing words in titles. "L@@K", "RARE", "MUST SEE". Nobody searches these, and they consume characters that could have matched something.

Internal product names. Your supplier's terminology is not what buyers type.

Relisting established listings. Discards the performance history the algorithm uses.

Mistakes that cost sales

Manufacturer copy used verbatim. Identical to every competitor. Nothing distinguishes you.

Missing information. Every pre-purchase message is a gap in your listing, and most people do not message — they leave.

Poor photography. Especially on used items, where a missing angle reads as something being hidden.

Hidden postage cost. Surprise cost at checkout is a leading abandonment cause.

No returns accepted. Affects both conversion and ranking on most marketplaces.

Desktop-only formatting. Wide tables and tiny text on a phone, where most buyers are.

Template banners above the content. Postage policy and shop branding pushing the actual product information below the fold.

Mistakes that cost you the account

These are a different category of severity.

Keyword stuffing with competitor brands. Against policy on every marketplace. Detectable. Results in listing removal and, repeated, account action.

Review manipulation. Incentivised reviews, review exchanges, buying reviews. Detectable, and on Amazon it is one of the faster routes to a suspension that is difficult to appeal.

Claiming compatibility you have not verified. Generates returns, defects, and eventually an item-not-as-described pattern.

Selling restricted or counterfeit items, including accidentally. Verify your supply chain.

Mistakes that are quietly expensive

Overselling. Stock not synced across channels. Produces cancellations, which become defects, which reduce visibility across the entire account.

Handling time you cannot meet. A two-day handling time you hit 70% of the time is worse than a four-day time you always hit.

Ignoring account health until sales drop. By the time you notice the sales, the metric has been bad for weeks.

Racing to the bottom on price. Repricing with no floor, or a floor that does not account for fees, postage and returns.

The pattern

Almost all of these are cheap to fix and invisible until you look for them. A listing audit across a catalogue — specifics, titles, photography, postage, returns — is usually the highest-return day available to an established seller, and it needs no new stock.
