General Questions  - 
 
Hi there,

I have a question about the container script. Why has the script to be placed immediate after the opening <body> tag?

One of the reasons is probably the <noscript> with the iframe, that will cause problems in some browsers.
But what if I move the <script> part of the container to the <head> en keep the <noscript> in the <body>? Does it have any effect on the data collection?

Why would I want that?
I want to execute the GTM container before the rendering of the page, because I use GTM to modify elements on the page. Currently the custom HTML tag with the JavaScript is placed in the bottom. So it is loaded and excuted later, and because of that I have a flickering effect. 
My hypothese is that when the <script> part is in the <head> the problem will be less. Just like a/b tools such as VWO & Optimizely. 

I love to hear your comments. And yes, I'm going to test it myself! :)

Thanks,
Simon

Hi Simon, of course you can place the script in the head (in most cases ideally directly before the closing head tag to not block other script/s), define the dataLayer object within this script tag but before the container code so GTM can access it directly on gtm.js, and place the noscript part with the iframe in the body (for example directly before the closing body tag). Nonetheless this won't solve problems with modifying elements and testing scripts as Stephane pointed out.

You may have noticed that Google Search on desktop looks a little different today.

Towards the end of last year we launched some pretty big design improvements for Search on mobile and tablet devices (mobile first! :-). Today we've carried over several of those changes to the desktop experience.

We've increased the size of result titles, removed the underlines, and evened out all the line heights. This improves readability and creates an overall cleaner look. We've also brought over our new ad labels from mobile, making the multi-device experience more consistent.

Improving consistency in design across platforms makes it easier for people to use Google Search across devices and it makes it easier for us to develop and ship improvements across the board.
