Google indexa el contenido generado por JavaScript

En We Tested How Googlebot Crawls Javascript And Here’s What We Learned se explica que Google desde el año 2008 indexa el contenido generado por JavaScript, pero parece que en los últimos años ha mejorado mucho lo que puede indexar:

  1. We ran a series of tests that verified Google is able to execute and index JavaScript with a multitude of implementations. We also confirmed Google is able to render the entire page and read the DOM, thereby indexing dynamically generated content.
  2. SEO signals in the DOM (page titles, meta descriptions, canonical tags, meta robots tags, etc.) are respected. Content dynamically inserted in the DOM is also crawlable and indexable. Furthermore, in certain cases, the DOM signals may even take precedence over contradictory statements in HTML source code. This will need more work, but was the case for several of our tests.
