There is no fixed limit on the number of Monetag ad formats you can run on one page. Onclick (Popunder), In-Page Push, Vignette Banner, Push Notifications, and a Direct Link can all work together.
More tags do not mean more income. Each ad zone should be placed on a page only once. If the same tag is pasted several times, every copy runs as a separate script: it slows down the page, interferes with the frequency settings of the zone, and does not bring extra revenue.
If you are not sure how to combine formats on your site, feel free to contact our support team via support@monetag.com with your site URL and zone IDs.
