Start making transactions and give good customer service and wait for the people you deal with to leave feedback..--Answer1:If you are a buyer, pay for your purchase quickly and leave positive feedback (if applicable) after you receive your item.If you are a seller, have good communication with your buyers...be clear about your policies in your ad so there wont be any question about exchanges, returns, what the person is bidding on/buying, etc. Let them know when the item has shipped and leave a tracking number (if applicable) so they can monitor its progress. Also be sure and leave them positive feedback if they paid promptly and there were no issues with the transaction..--Answer2:You have to bribe people to leave fake feedback..--Answer3:The easiest way: buy things (and pay immediately). Feedback from a seller counts the same in your rating as feedback from a buyer.Also, start out selling small things, and give great customer service. Buyers are more willing to take a chance with a new seller if the item isnt expensive. Then as you build up your rating, you can sell more expensive items.Most importantly, if someone doesnt give you feedback within about a week after the transaction has been completed, write to them and politely request that they do. Most people will leave feedback if you have done a good job, and you request it.Good luck.Larry (ebay Power Seller)
