Custom site google search


Hi all,

I was wondering how I can implement custom search in my HubSpot site. My templates are custom code and not using the drag-and-drop builder.

I read this article and know how to make it using the google custom search engine -

But that option has ads and I want a clean version. The issue is that google is shutting down their paid version of custom search -

Is there an solution for this within Hubspot?
