Google Rich Snippet with ajax pagination

Question

I write an embedded widget which show reviews which uploads dynamically in batches. I would like to use Google Rich Snippets for Reviews not just AggregatedRating.

I'm adding Google Rich Snippets using JSON-LD format dynamycally when I'm lazy loading reviews.

Does Google Crawler work for all reviews on page or is it required any extra features for pagination?

Thanks for any response (resources, books, blogs).

Answer 1

A brief clarification. Google uses a controlled vocabulary defined by schema.org. Publishers may present information using schema.org terms. If a Publisher uses terms from schema.org, it also must structure the information to conform to the schema.org grammar. For example, for your Reviews, terms for AggregateRating must be allowable and complete (Google requires specific data). When a Publisher presents structured information, it may expose the data to humans on a web page using Microdata (Rich Snippets) or RDFa. If the Publisher has correctly used the schema.org terms and grammar, the Google Crawler will parse and correctly interpret the information.

Publisher also may present information in a machine-readable format. That format is JSON-LD. The JSON-LD structure could package a collection of Reviews on a single page. Publisher will want to make sure that the meaning of the JSON-LD structure has the same meaning as the HTML markup (either Microdata or RDFa). Google may marginalize a site where human-readable data is not semantically equivalent to machine-readable data.

You ask about "extra features" for pagination. The JSON-LD can be packaged as a single structure to describe all semantic information on a page. That structure may be anywhere in the HTML document. If you chunk your Reviews in some order on the page, the RDFa or Microdata will be associated with the chunks. Otherwise, I'm not use what you mean by pagination. You ask: "Does Google Crawler work for all reviews on a page?" The answer is yes.
