How to increase Blogger speed in 2026

Blogger (Blogspot) sites are still struggling with speed in 2026—not because Blogger is slow, but because most blogs are poorly optimized.
The good news? You can dramatically improve your Blogger loading speed without migrating to WordPress or hiring a developer.

This guide shows exactly how to increase Blogger speed in 2026, based on current Core Web Vitals, Google ranking signals, and real-world testing.

After WordPress, Blogger(Blogspot) is the second most popular platform for bloggers. There are over 600 million blogs on the web, and about 20 to 25 percent is on bloggers. 

But when it comes to resources, the blogger has limited options. On WordPress, you can get tons of plugins that will help you to increase website speed and performance, but on Blogger, most of the job is done manually. So if you want to optimise your website, then read carefully and follow the steps.

How Blogger Speed Works in 2026 (Simple Explanation)

Blogger is hosted on Google infrastructure, so server speed is not the problem.

Blogger performance depends on:

• Theme code quality
• Image size & loading behavior
• Third-party scripts (ads, analytics, widgets)
• Render-blocking CSS & JavaScript

Go to the Google website speed test tool and enter your website URL. It will take 30 seconds to 2 minutes, depending on your website size.

There are two options for different devices like mobile and computer. You can find different speeds for different devices.

You will get a result, something like the pictures below showing metrics like 

• First Contentful Paint – Time for the first piece of your DOM content to be rendered.
• Time to Interactive – Time to load the most important content of your page.
• Speed Index – How fast the content is displayed when the page is loading.
• Total Blocking Time – Total blocking time when an event has occurred like a mouse click or keyboard press.
• Largest Contentful Paint – Time is taken to render the largest content of the page.
• Cumulative Layout Shift

Remove unused JavaScript

JavaScript is a slow language, and having too much JavaScript can increase your page loading time. In a theme, there can be much unused JavaScript. Pagespeed insights show you the list of unused JavaScript, you can remove them one by one by copying them and finding the same in your theme.

Minify your Blogger code to reduce the website size so that it loads faster.

What is Minify

When most programmers or web developers write code, they write in a beautiful manner so that it’s easy to write and read the code in the future, but for bots or for the rendering process, it does not matter whether the code is written beautifully or not. 

Beautifying your code increases the theme size and results in slow speed. Below is an image to know the difference between beautify code and minify code.

 

Minifying code that is written separately is easy, as you can find many online tools but blogger code are in XML, and all codes like HTML, CSS, and JavaScript are on a single page. So minifying blogger code is a tricky one. Just follow the steps I have shown in the following video one by one to successfully minify your Blogger code.

Use a Lightweight Blogger Theme (Most Important)

Avoid:

• Multipurpose themes
• Themes with sliders, animations, page builders
• Old themes (pre-2021)

What to look for:

• Minimal CSS
• No jQuery dependency
• Native lazy loading
• Mobile-first design

A clean theme alone can improve LCP by 30–50%.

Optimize Images the Right Way

Images are the #1 speed killer on Blogger.

Best practices for 2026:

• Use WebP format
• Compress images before upload
• Max width: 1200px (blogs)
• Avoid PNG unless necessary

Enable lazy loading:

<img loading="lazy" src="image.webp" alt="description">

Remove Unnecessary Widgets & Gadgets

Common slow widgets:

• Visitor counters
• Related posts scripts
• Auto-loading social embeds
• Third-party comment systems

Rule:
If it doesn’t directly help SEO or UX—remove it.

Delay & Defer JavaScript (Critical for INP)

Scripts that should be delayed:

• Google Analytics
• Ad scripts
• Heatmaps
• Social sharing tools

Example:

<script defer src="script.js"></script>

This alone can cut INP by 40–60%.

Reduce Google Fonts & External Requests

Common mistake:

• Using 4–5 font families
• Loading unused font weights

Best practice:

• Use 1 font family
• Load only required weights
• Prefer system fonts if possible

Fix Layout Shifts (CLS)

CLS issues come from:

• Ads loading late
• Images without dimensions
• Dynamic widgets

Fixes:

• Define image width & height
• Reserve space for ads
• Avoid auto-resizing embeds

Advanced Blogger Speed Optimization (Optional)

Use a CDN (Works Well in 2026)

While Blogger controls headers, you can:

• Reduce file changes
• Use fewer external assets
• Avoid cache-busting parameters
