Earlier quoted context omitted.
Your comment does not make any sense to me. Are we talking about the same thing? A snippet is a summary of the page served by the search engine. The publisher currently does not have any idea that a particular user has seen a snippet, so publishers do "know the same amount" as they did before with AMP, which is nothing. > Is that how you feel about regular search results? Regular search results have snippets.
I'm sorry that you were having difficulty interpreting my comment. It may help if you go back and note that I was making a distinction between using AMP to consume content vs search for it. Publishers normally know when their content is being consumed. Let me know if that makes sense to you. >Regular search results have snippets. Right, and I was asking about the search results, not the snippets that accompany them.…
They still know when their content is being consumed. They just don't know when their content is being searched for until the user clicks their link, exactly like a snippet. Does that make sense now? My point was that search engines already show cached portions of the page. Read the parent comment of my first "snippet" comment to understand why I was making that point.
