Meta tags in Single Page Apps

[TrueluxGroup]

Since the deprecation of the AJAX Crawling Scheme back last October I am curious as to when Googlebot actually reads meta tag information from a page.

We have a website at whichledlight.com that is implemented using emberjs. Part of the site is our results pages (i.e. gu10-led-bulbs). This page updates the meta and link tags in the head of the document for things like canonicalisation and robots, but can only do so after the page finishes loading and the JavaScript has been run.When the AJAX crawling scheme was still in place we were able to prerender these pages (including the modified meta and link tags) and serve these to Googlebot. Now Googlebot no longer uses these prerendered snapshots and instead is sophisticated enough load and run our site.So the question I have is does Googlebot read the meta and links tags downloaded from the original response or does it wait until the page finishes rendering before reading them (including any modifications that have been performed on them)

Hi ipressman,

You've asked some great questions! I encourage you to start a new thread of your own for each one and provide a few more details in order to get the best responses.

As this thread is quite old, I'm going to lock it to new responses. Thanks for your understanding!

Hi TrueluxGroup! Did Oleg answer your question, and if so, would you mind marking his response as a Good Answer?

If not, what can we still help you with?

Thanks for getting back to us. Never knew I coudl look at the index source like that. Amazing! It is however as I expected and it has not cached/indexed the updated head of the document which is altered by the JavaScript. That is going to be very problematic for us. Thanks for you help

Here is what Google sees and indexes for that page: http://webcache.googleusercontent.com/search?q=cache:https://www.whichledlight.com/t/gu10-led-bulbs&num=1&strip=0&vwsrc=1
