Yes: you can add Monetag tags to a site that already runs AdSense. Google allows ads from other networks and affiliate links on the same page (see Google’s guidelines), as long as the site follows the AdSense Program policies and does not contain more ads than content. Below is what Google’s policies say about each type of ad, so you can decide what to place next to AdSense.
Formats that can run alongside AdSense
Push Notifications, In-Page Push, Vignette Banner, and Direct Link do not open new windows or tabs on page load, so they can generally run together with AdSense. Make sure they do not cover or move Google ad units, and keep the total number of ads on the page reasonable.
OnClick (Popunder)
OnClick works a bit differently from other formats. Google’s ad placement policies limit pop-ups to three per site and do not allow Google ads on sites that trigger pop-unders. Pop-ups also may not interfere with site navigation, change user preferences, initiate downloads, or distribute viruses.
How AdSense and Monetag work together
AdSense mainly matches ads to the content and keywords of your page. Monetag matches ads to the user: GEO, device, platform, activity, and interests. The two approaches complement each other, so adding AdSense-compatible Monetag formats can bring additional revenue without replacing AdSense.
Keep the number of ads reasonable, do not place more ads than content on the page, and check that none of the ads interfere with site navigation.
