There is a lot of conflicting advice about product descriptions online. Some of it is useful. A fair portion of it is repeated without much scrutiny. For anyone just starting out, a few specific myths tend to cause the most confusion.
Myth one: copy from competitors and adjust the wording
This is a practical shortcut that creates a slow problem. If your description reads like every other listing in your category, there is no reason for a buyer to choose yours specifically. Competitor descriptions also carry their errors and gaps forward. Starting from what your actual product does is slower but produces something that reflects your specific item.
Myth two: SEO keywords should drive the writing
Keywords matter for discoverability, but a description written around keyword density rather than buyer questions is obvious and unpleasant to read. The more useful approach is to write for the reader first, then check whether the natural language already includes relevant terms. It usually does.
- Write for the person deciding whether to buy
- Answer the most common questions about the product
- Check keyword coverage after the draft is done
Myth three: good photos replace the need for a description
Photos show what something looks like. They do not communicate weight, texture, compatibility, care instructions, or what problem the product solves. A photo of a linen pillowcase tells you the colour. The description tells you it is pre-washed, stays cool, and fits a standard queen pillow without bunching. Those details close the sale.
Descriptions and images answer different questions. Both are doing separate work.
