Disadvantage of Lazyload Google Analytics

Implementing Lazyload of Analytics code in the Website can impact your analytics data. It will not be able to track views if a user closes the page before a complete load of a page. 

But, it is completely fine as it makes no sense to track a user that doesn’t even load the page completely. 

Here, also note that the subsequent visit of a user will not impact the analytics data as it has already cached in the browser.  That’s why I strongly recommend you implement Lazy loading of Analytics code in your blogger website.
