Reseller Tips
Use these quick reseller tips to write cleaner, easier-to-scan listings before you post.
1. How to Write a Product Title That Fits Every Platform
Start with the words buyers actually search: brand, item type, style, color, and size. Avoid using your first 60 characters on vague words like “cute,” “wow,” or “must see.” A strong title should help a buyer understand the item before they click.
2. How to Shorten a Long Reseller Description
If your description feels too long, remove repeated words, long sentences, and extra personality phrases. Keep the most important details: what it is, condition, size, color, material, measurements, flaws, and what is included.
3. Why Measurements Help Reduce Buyer Questions
Measurements help shoppers feel more confident, especially with clothing, shoes, handbags, and home items. Add key measurements when possible so buyers do not have to message you before purchasing.
