I am curious about why use
SearchResultsPage? (See the definition SearchResultsPage - schema.org.)
In 2007, Matt Cuts said that Google Search does not like to index search results in websites (ref: Search results in search results). Many people also recommended to use
<meta name="robots" content="noindex, follow" />, and let the search engine not index the page, but follow the links on the page.
Since the Google search engine does not like to index search results in websites, why use
SearchResultsPage? And, if using
SearchResultsPage, are there any rich snippets effect on Google search result pages?
