Checking Your Page Size for SEO: A Complete Guide

Desktop and mobile speed is shooting high with fourth and fifth-generation internet. With the advent of advanced technologies, page size doesn’t seem to be a big deal. But, small web pages add up to tons of data. 

Moreover, many users using multiple pages can take page speed down the drain. Now, it is a horrific show. Wait! If web admins take care of page size from initial stances, it will remain under control. 

Page Size is an ultimate factor for boosting user experience and satisfying core web vitals. Let’s figure out its importance, tips to achieve this, tools, and page size relevance for SEO.

Standard page size range

Do you know Google is very strict about Core web vitals? It determines page indexing and rankings based on these factors.

Most of the web admins try to keep page size 100 kb or less. When the browser loads a page, it generates an HTML document object model (DOM). Page size varies from industry to industry or niche. Large websites like eCommerce HTML DOM page size may go up to 150-200 kb. 

But, it is unrealistic to think page size in MBs. But some websites take their page size to this extent by adding many elements to it. It doesn’t serve any good purpose but negatively affects SEO to a large extent.

Factors that influence page size

Important factors that contribute to page size are:

CSS and JS

Cascading style sheets determine the presentation and appearance of the website. On the other hand, JS controls the overall programming of the page. 

Well, extra code can create code bloating. It leads to decreasing page speed. Minify CSS and JS files to ensure smooth working of the page.


Programmers can control HTML DOM strategically. A large HTML DOM is detrimental to page speed. Indeed, it affects runtime performance and takes a toll on memory efficiency. So, reduce the HTML DOM tree size to as minimum objects as possible.


HD images having large sizes are the worst page size factor—the image of 32 MB takes 2 minutes to load. You have already lost the SEO game! Without monitoring image size, page speed can’t improve.


Unnecessary redirects can affect the page size badly. Web crawlers need to move from one page to another. It reduces page speed significantly.

Page speed leaves a positive first impression. And it helps in improving customer retention rate. Furthermore, it not only gives enhanced user experience but also increases search engine rankings.
