Where to look for ready-made landing page pages already with products?

Question

Landing pages

Hello.
Please tell me how to formulate a search query in order to find landing pages with products that are already being sold and are fully working?
I wanted to look at the different varieties of existing landing pages that sell products. See what is convenient and what is not, and based on this analysis, create your ideal page.
I have not done this for about a year and therefore it is necessary to understand and evaluate the existing ones in order to have an idea in my head.
Google gives me templates, creation services, or top cool landing pages. Here you need to enter some product separately in order to stumble upon a landing, which is not productive. I really hope that someone will help me figure out this seemingly simple task at first glance.

Contextual advertising and all advertisers in it.
