New Adsense code(?)

Hello,

May be this is something old, but I just noticed that, the code provided by Adsense is slightly different, from what it used to be:

Instead of :

<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>

it's now

<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?client=ca-pub-xxx" crossorigin="anonymous"></script>

The crossorigin parameter is to deal with Cross-Origin Resource Sharing mechanism.

Also, now, the publisher id is directly added as a parameter to the "adsbygoogle.js". I wonder which kind of impact this has, since the "old" code continues to works. I wonder if it's safer, faster (may be one less round-trip, etc...)

Interesting.
I wonder what difference does it make in practice.

I hadn't noticed this. I wonder if I should update my existing ad code? Hmm...

Hello,

I've implemented the change, I see no negative impact (hopefully!), my coverage and active view viewable increased by 10% , but it might be pure coincidence.

Addendum : I am sure this is a placebo effect, but I have the impression that Ads are "less slow".

@JorgeV "view viewable increased by 10%" - good enough reason for me to try at least. TY

I've implemented the new code on one site - so far nothing positive/negative to report after 36 hours. It's probably the new generation of ad code you'll see on all new ad blocks created - something, something to help Google do something.

The one obvious change is the addition of a "crossorigin" attribute, this is no doubt related to CORS headers. I'm not sure how it is used or even if it is used at this point but it is important in terms of security. Here as article explaining CORS.

my coverage and active view viewable increased by 10%

I doubt that the AVV would be impacted, but the code could change coverage, as some browser may block the Adsense script due to CORS restrictions (I'm just speculating)

I emailed AdSense about whether I should update my existing ad code and this was their reply:

Thank you for reaching out. Your existing ad code will continue to work. If there is ever required that you update your AdSense code blocks, you will be given a proactive heads up. That said, you are welcome to copy and paste the latest ad code from your account at any time. I hope this helps. Please let me know if you have any questions.

I just checked my Adsense account to see what code was returned for my existing ad-units and it shows this new code. So it looks like you can update it without impact you the data of existing ad-units. I will probably up to date mine when I have some free time, but I wont be stressing over this.

My new code doesn't have the crossorigin addition:

<script data-ad-client="ca-pub-XXXXXXXXXXXXXXXX" async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>

Google reverted the new adcode, Something wrong with it.
I reverted back to old code.

It is not reverted. At least i see still code below


<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?client=xxxxxxxxxxx"
   crossorigin="anonymous">

I'm seeing the same as Niresh and have my code reverted as well. (<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>)

I've decided to revert back to the old code. On long pages where I had an ad tag repeating many times, I was getting almost double the impressions with lower viewability numbers. I'm guessing the new code wasn't lazy loading as it was with the original tags (did not find out for sure using dev tools).

mine has reverted back to the old code as well, but I think I'm going to leave the new one on for a while.
the impressions are up but that's probably just because of bank holiday weekend. active viewable is the same, but page rpm is up so earnings are up

For completeness, Google announced the new code [support.google.com...]

The js loads quite a bit faster, according to multiple waterfall tests of sites with and without the new code. That's the only difference I have seen so far. No apparent impact on revenue.

Maybe that's what Google means when it says the code will "improve the performance" of ads.

It's really weird that it would load faster and not reflect on impressions, clicks and earnings.

"It's really weird that it would load faster and not reflect on impressions, clicks and earnings."

Adsbygoogle.js is a single file among many that make up the display of ads. The client ad files are numerous and usually much bigger. They aren't impacted. So the total display may be only be a few percentage points faster, which makes it difficult to prove any impact on earnings. Just a guess.
