I want a basic search engine script website. The website can have Google API or anything you prefer for delivering the search results. I want to have the ability to add advertisement layover to the search query page.
I search "pasta" on the search website, the next page that opens will be "pasta" search query with results. I want the ability to add a big layover pop-up an advertisement on that page with a close button.
The website has to be responsive and work excellent on mobile as well.
