No. In-Margin ads will not conflict with any existing ads on your website(s). All In-Margin does is that it displays ads along the L.H.S and R.H.S margins of the web browser. It’s like adding a new layer on the sides of the screen. It does not modify any content behind it. Even when users scroll up and down, the ad display unit sticks to the sides/margins of the web browser. With In-Margin, you can choose the specific pages on which ads will eventually be displayed.
