Web Bloat Score (WebBS): Everyone knows that most of today's websites are "overweight," but there's no way to measure the amount of bloat.
Yes, you can find out and check the total size of the download, but kbs or mgs are not the issue. For example, a Google search results page is very “overweight” if it is very small (from 10K to 464K), and a page that is full of images may not be overweight, even if it contains several megabytes.
Željko Švedić has created a website that offers a solution to the problem, as it provides a very simple rating of the bloat that sites contain. The idea is simple.
The Web Bloat Score (WebBS) page compares the download size of the target page to the size of a png image of the page.
Today there are websites with 3MB or even 5MB pages and they are quite common, although they seem to use more text than images.
Basically, a non-bloated page should score less than 1, and scores of less than 0.5 are certainly possible. Tim Berners-Lee's W3C page (one of the examples Švedić uses) scores 0.204. "Bloated" pages on Google SERPs naturally score higher, at 7.38.
There are many obvious reasons for a page to over-inflate. Interactive elements on the page, JavaScript libraries, the Analytics infrastructure for tracking users, and of course, ads.
As you can see, removing all of the above is practically impossible, but it can certainly lead to websites that load and respond faster, which will please all users.
