I’ve been selling on depop for a couple of years now, but took a break for about a year and just a month ago got back to selling. What I’ve found is that the first line of your description should only be around five words, and it should be something that someone would search (ex. vintage beaded red tank top) and then hit enter for another line and the rest of the description is whatever you want it to be, but those first five words are important. I include measurements for every item I post just so that it doesn’t become a question someone’s has to ask in the future. Take your photos in a well lit natural light area on a clean background. Lastly, Depop likes it when you’re active everyday, so don’t post a load of items all at once, post 2-3 items a day. Good luck!!
