Will exit intent layer harm google ranking? What if third party ad in exit intent layer?

[lcourse]

We plan to implement an exit intent layer.
For mailing list expansion and/or to display personalized third party advertising.

Any negative impact this may have on google rankings?
Shall we limit exit intent layer so to show only to users who visited at least 2 pages on our site?
Shall we reduce size of layer on mobile?
Anything else to consider to minimize potential negative impact on google rankings?
