To set up automatic bidding for eBay auctions, you first need to log in to your eBay account, then go to the page of the product you want to auction, find "Set up automatic bidding" at the bottom of the page, and click to enter the settings page.

On the settings page, you can select the maximum limit for automatic bidding, and you can also set the frequency and time of automatic bidding to ensure that you can successfully bid at the last moment.

After the settings are completed, carefully check the setting information, and click "Save Settings" to complete the settings after confirming that they are correct. The automatic bidding function allows users to easily win their favorite products without having to wait for the auction all the time.
