So i have a website where i have added a small popup in the inner pages, it appears 15 seconds after the user is on the page and shows the banner of same sites android app which links to playstore, so it is very relevant to the users. Popup closes after 20 seconds automatically. So my question is , if this is bad for SEO? My sites home page is ranking top 3 for quite big keywords, but i am not adding the popup on home page, just the inner pages... Suggestion needed from experienced members... thanks.
