Web Bloat Score (WebBS): Everyone knows that most of today's websites are "overweight", but there is no way to measure the amount of bloat.
Yes, you can discover check the total download size, but kbs or mgs are not the issue. For example, its search results page Google it is very "overweight" if it is very small (from 10K to 464K), and a page full of images may not be overweight even if it contains several megabytes.
Željko Švedić with the creation of a website offers a solution to the problem, as it provides a very simple score of bloat sites. The idea is simple.
The Web Bloat Score (WebBS) compares the size of the target page's size with the size of a page image in png.
Today there are websites with 3MB or even pages of 5MB and even quite common, although they seem to use more text than images.
Basically a non-"inflated" page should score less than 1, and scores of less than 0.5 are definitely possible. Tim Berners-Lee's page at the W3C (one of Švedić's examples) scores 0,204. "Inflated" websites with Google SERP of course have a higher score, they catch 7,38.
There are many obvious reasons for para-bloating a page. Interactive page components, JavaScript libraries, Analytics infrastructure for monitoring of users and of course the advertisements.
As you can see, removing all of the above is practically impossible, but it can certainly lead to faster loading and responsive websites, which will please everyone. users.
