Summarize:

If you take bad or blurry pictures, the chances of you selling your item are very slim. Use your iPhone’s camera to take the pictures. Tap "Sell" from the bottom menu. You will be brought to the Sell screen where you will need to provide information on the item you’re selling. Make the ad title eye-catching, short and to the point. Tap "Choose Photos." Upload the pictures you want to use from your camera roll. Make your price realistic and practical for the item you’re selling. If it’s too high, people might ignore it. If it’s too low, people might think it’s a scam. Describe your item accurately. Clearly state if it’s brand-new or used.  A good description will attract more buyers and require less effort to manage questions. Where is the item located?  Buyers will also consider your location and distance from them to determine if they can do meet-ups or ask for shipping. Properly select the category related to your item. It will get better exposure under the right category. Is the item brand-new or used? Once you’ve properly set up the ad, tap "Done" at the top of the screen. Your ad will be sent to Team OLX for review and approval. If you and a buyer make a deal, then you can consider your item sold. Complete the terms of your deal before marking your ad as sold.
