Advertisements help to offset the pricing for your Live365 broadcasting subscription. Depending on how many ads are heard by your listeners, you can be paid a portion of the advertising revenue as detailed in the Advertising Revenue Share Program. (More information on revenue sharing can be found here).
You have the option to go Ad-free and opt out of the the Advertising Revenue Share Program, but the price of your Live365 broadcasting subscription will increase. If you have not opted out, as per the conditions outlined in the Advertising Revenue Share Program, you must play 4 minutes of advertising per hour. In other words, 56mins of music to 4mins of ads. As a broadcaster, you have the ability to regulate the frequency of ads to music via the following ratios:
Step 1) Log into your Live365 broadcaster account.
Step 2) Click on "Settings" tab of the Navigation Bar.
Step 3) The "Settings" tab will expand, then click on "Auto DJ"
Step 4) In the Auto DJ pane you can now select the frequency of your ad spots (30, 60, or 120 seconds) under the Advertisements section of the AutoDJ Settings pane.
