Make your title short but descriptive. Try to avoid words like "must see", "wow". No buyers would search for those words. Use common keywords related to the placement category and your item, which buyer might use during the search.
Attachat list one image to your free classified. Ads with attached images usually attract more attention from buyers. Show off your item by attaching up to 5 images. If you have an online image, then provide a URL link to it during ad placement. Note: An online image would not have a thumbnail view on an ad display page.
