JavaScript SEO surprise! TL;DR: - Google announced they don't use JS-injected canonical tags. - Our new test shows they DO. - GSC index coverage report also wrong. What do you think? I'm looking forward to hearing your opinions. Full story here:https://www.searchviu.com/en/javascript-canonical-tags/ …

This was a cool test setup, thanks for running it! A few things: what we said at I/O (re: rel-canonical via JS) was more of a warning. When I saw that internally, I wanted to let folks know, because it was unexpected to me (& imo it would be good to support it).
Going through your example, it looks like it does work, at least sometimes (see? great test!). IMO I would not rely on this though, if you really want a URL as a canonical, do the work to get the signal in right from the start.

well I would say JS injected canonical tags works since 2 years.
@WebthrustCom works based on this :) -
That tool looks pretty cool o_O

So does the cache update after the WRS completes like
@Adoubleagent mentioned? -
Ignore those comments. I was mistaken. As far as I know the cache displays source code SSR not client-side rendered objects. I am probs mistaken on that as well.
