At the time, this announcement was a game changer that enriched SEO strategy. But not too long after, companies like Hulu started to uncover holes in Google’s claim of complete compatibility with JS.

Below you can find the three tests we conducted to prove the crawlability of PowerReviews review content:
The First Test
First, Loud Interactive performed a test based on a Chrome 41 Selenium WebDriver. The tool took 95,196 of PowerReviews’ JS powered ‘Display 4’ review URLs and rendered them in the Chrome 41-based crawler. Then, it checked for the presence of the PowerReviews CSS classes, indicating the reviews were present in the page’s DOM and could be indexed. The test showed that PowerReviews review content, populated via JS, is properly rendered for Googlebot.
The Second Test
Second, Loud Interactive performed a simple test to validate whether a URL was indexed by Google. This tool uses the Google API and the same export of 95k PowerReviews URLs, appends “info:” to each URL and verifies that Google returns results. URLs that were not included in Google’s index were run through a popular web crawler, Screaming Frog, to determine if the Googlebot search engine crawler encountered 4xx or 5xx errors for reasons not related to JS. If so, these URLs were isolated from URLs that properly rendered and indexed.
The Final Test
Lastly, Loud Interactive checked the Google Index for direct quotes pulled from the review copy. A sample set of PowerReviews URLs with review content and headlines were exported. Using the Google API and a custom built tool, Loud Interactive was able to verify both indexation and rankability of the reviews by comparing the URL list of where the quoted review content was taken and the URLs that ranked within Google for the review content.
