If you have been blogging on Blogger for a while, you have probably opened your site on your phone at some point and felt that sinking feeling when the page just sits there loading. You tap the screen. Nothing happens. You wait a few more seconds. Still loading. That experience is not just annoying for you as the site owner. It is actively pushing your readers away, and more importantly, it is telling Google something you do not want it to know: that your blog is slow.
I went through this exact problem when I was building out my Lightrux blog. I had a theme I liked, a handful of posts live, and traffic starting to trickle in through Search Console. But when I ran my first speed test, the score came back in the red zone on mobile. Not borderline. Genuinely red. That sent me down a rabbit hole of testing, tweaking, and learning what actually moves the needle for Blogger specifically. Not WordPress. Not a self-hosted site with server access. Blogger, with all its quirks and limitations.
This post is everything I figured out from that process. If you are on Blogger and you want to know how to increase your website speed without touching a server config file or paying a developer, you are in the right place.
Why Website Speed Matters More Than You Think
Before getting into the fixes, it is worth spending a moment on why this is worth your time. Speed is not just about user comfort, though that matters a lot. Google officially uses page speed as a ranking signal through a set of metrics called Core Web Vitals. These include how fast your main content loads, how stable your layout is as it loads, and how quickly the page responds to user interaction.
According to Google's PageSpeed Insights documentation, the tool measures real-world performance using Chrome user data as well as simulated lab conditions. A page that scores below 50 is considered poor. Between 50 and 89 is average. Anything 90 and above is where you want to be.
For Blogger users, the good news is that Blogger hosts your content on Google's own servers. That gives you a head start on raw hosting speed compared to cheap shared hosting. The bad news is that the things slowing your Blogger site down are almost always self-inflicted: oversized images, heavy third-party scripts, bloated themes, and fonts loaded in ways that create visible delays. All of those are fixable, and none of them require server access.
Step One: Test Your Current Speed Before Touching Anything
The first thing you need to do is establish a baseline. Do not start making changes without knowing where you stand, because otherwise you have no way of knowing whether anything you do is actually working.
Go to Google PageSpeed Insights and paste in your blog's URL. Run the test on both mobile and desktop. Write down the scores. Pay particular attention to the mobile score, because that is the one that matters most for SEO. Google indexes your site using the mobile version first, so your mobile performance is what Google is actually measuring when it decides how to rank your content.
Once you have your scores, scroll down in the PageSpeed report and look at the Opportunities and Diagnostics sections. These tell you exactly what is causing the slowdown and roughly how much improvement each fix is expected to deliver. This list becomes your to-do checklist for everything that follows in this post.
Step Two: Optimise Every Image Before You Upload
Images are the number one reason Blogger blogs load slowly. I say that with confidence because it was my own biggest problem and it is the most common issue I see flagged in speed reports for Blogger sites. People take a screenshot, upload it directly without compressing it, and Blogger serves that full-size file to every visitor who loads the page.
There are two things you need to do here. First, compress every image before uploading it. A tool like TinyPNG lets you drag and drop PNG and JPG files and compresses them significantly without any visible quality loss. I use this for every image I upload to Lightrux. A screenshot that was 800KB before compression often comes out at under 150KB after, which is a dramatic improvement in what the browser has to download.
Second, think carefully about the dimensions of your images. If your blog's content column is 700 pixels wide, there is no reason to upload a 2000-pixel-wide image. Blogger will display it at 700 pixels anyway, but the browser still has to download the full 2000-pixel version. Resize your images to match your content width before uploading, then compress them with TinyPNG on top of that. That combination makes a noticeable difference.
One more thing worth mentioning here: on Blogger, when you upload an image through the post editor, Blogger stores it on its own CDN and automatically serves it through Google's infrastructure. That is actually good for speed. But none of that infrastructure helps you if the original file you uploaded was unnecessarily large. The optimisation happens before the upload, not after.
If your posts include screenshots, this is especially relevant. I covered a specific issue with blurry screenshots on Blogger in detail in this post about how to fix blurry images on Blogger. That post explains what causes the blurriness and how to upload screenshots that stay sharp, which connects directly to how you should be handling image quality and size before uploading.
Step Three: Choose a Lightweight Theme or Strip Down Your Existing One
Your Blogger theme is the single biggest architectural factor affecting your site speed. A bloated theme with dozens of decorative elements, heavy CSS, multiple font imports, and third-party widget integrations will tank your PageSpeed score regardless of how well you optimise everything else.
When I built the Lightrux theme, I made a deliberate decision to keep the CSS as lean as possible and to be very selective about what scripts I loaded. Even then, I had to go back and strip out things that were hurting performance. One of the most impactful changes I made was removing a Google Fonts import that was loading the Syne font at weight 800. That single change eliminated a Flash of Unstyled Text issue that was affecting the Largest Contentful Paint score on mobile.
If you are using a theme you downloaded from somewhere, open your theme's HTML in the Blogger theme editor and look at what is being loaded in the head section. You are looking for:
- Multiple Google Fonts imports (each one is a separate network request)
- Scripts loaded without async or defer attributes
- Third-party widget scripts from services you are not actively using
- Large inline CSS blocks that load styles for elements your blog does not even use
Removing unnecessary Google Fonts imports alone can take a mobile PageSpeed score from the 50s into the 70s. If you need a font, load only the weights you actually use. If you use one font at one weight, import only that. The difference in load time is significant.
Step Four: Remove or Limit Third-Party Scripts
Every third-party script on your blog is a potential speed problem. Third-party scripts are anything that loads from an external server that is not Blogger's own infrastructure. This includes things like social sharing buttons that load JavaScript from other domains, chat widgets, pop-up tools, comment system replacements, and analytics scripts beyond the two that every blog genuinely needs.
The two scripts worth keeping are Google Analytics and Google Search Console verification. If you use Google AdSense, that script stays too. Beyond those three, look critically at everything else on your blog and ask whether it is adding enough value to justify the load time cost it is creating.
Social sharing widgets are one of the worst offenders because they often load several scripts, stylesheets, and fonts of their own. A simple set of plain HTML links to your social profiles loads in milliseconds and causes no speed penalty at all. The sharing widget that loads from three different domains and pulls in a custom font? That can add half a second to your page load time on mobile.
Step Five: Fix How Fonts Are Loading
Google Fonts is one of the most commonly used font services on the web, and it is also one of the most commonly misused from a performance perspective. The default way most themes load Google Fonts creates a render-blocking request, which means the browser stops loading your page content while it waits to download the font. This is one of the most common causes of poor First Contentful Paint scores on Blogger.
There are a few ways to handle this better. The most straightforward option within Blogger's constraints is to add display=swap to your Google Fonts URL. This tells the browser to show the fallback system font immediately while the custom font loads in the background, rather than blocking the page render entirely. Your font URL should look something like this:
https://fonts.googleapis.com/css2?family=DM+Sans:wght@400;600&display=swap
The display=swap parameter at the end is what makes the difference. Without it, many browsers will hold the page render until the font is fully downloaded. With it, the page loads immediately with a fallback font, then swaps in the custom font once it is ready. The visual swap is usually imperceptible to readers, but the speed improvement is real and measurable.
If your PageSpeed report is flagging font loading as a major issue and you are willing to go further, consider whether you actually need the custom font at all. System fonts like Georgia, Trebuchet MS, and the system-ui stack load instantly because they are already on the user's device. For a blog whose main goal is getting AdSense approval and building organic traffic, a clean system font stack is a completely legitimate choice that costs you nothing in speed.
Step Six: Keep Your Post HTML Clean
This one surprises people, but the HTML inside your actual blog posts can contribute to slow load times if it is carrying a lot of unnecessary code. This happens most often when you copy and paste content from Microsoft Word, Google Docs, or another website into the Blogger Compose editor. Those sources embed invisible formatting code that Blogger preserves and sends to every visitor's browser.
When I first started writing posts in Blogger, I used to draft in Google Docs and paste directly into Compose. The HTML that ended up inside my posts was full of span tags, inline styles, and class references that did nothing visible but added to the page's overall code weight. Switching to writing directly in Blogger's Compose editor, or pasting clean HTML into the HTML view, solved that completely.
If you are writing posts in the Blogger HTML view rather than Compose, keep your markup simple. Use basic heading tags, paragraph tags, anchor tags for links, and list tags where needed. Avoid wrapping everything in div containers with inline styles unless you have a specific layout reason. Clean, minimal HTML is faster to parse and render than cluttered code with dozens of nested elements.
Step Seven: Reduce the Number of Posts on Your Homepage
Your homepage is often the heaviest page on your Blogger blog because it loads multiple posts at once. Each of those posts brings its own content, its own featured image, and its own metadata. If your homepage is set to show 10 or 15 posts by default, that is a lot of content the browser has to process before the page can be considered loaded.
Go to your Blogger settings and look for the number of posts shown on the main page. Reducing this to five or seven posts is a practical compromise that keeps the homepage useful while reducing the amount of content that has to load on the first visit. This is especially impactful on mobile, where network conditions are less reliable and processing power is more limited than on desktop.
Step Eight: Use Google Search Console to Track the Impact
Once you have made these changes, you need a way to track whether they are actually working. Google Search Console has a Core Web Vitals report that shows your site's real-world performance data based on actual Chrome user visits. This is different from the simulated scores in PageSpeed Insights, because it reflects how real users on real devices are experiencing your blog.
The Core Web Vitals report categorises your URLs as Good, Needs Improvement, or Poor. Once you have implemented the changes in this post, give it a few weeks and then come back to this report to see whether the Good count has increased. Search Console data takes time to update because it relies on real user visits accumulating over time, so patience is important here.
If you are not yet set up with Google Search Console, the free SEO tools post I published covers how to get started with it as a Blogger user. The best free SEO tools for Blogger post walks through how to connect Search Console to your blog, verify ownership through the HTML tag method, and use the coverage and performance reports effectively. Speed is one part of what Search Console tracks, but it is connected to indexing and ranking performance in ways that make all of those reports worth monitoring together.
Step Nine: Make Sure Your Blog Has a Custom Domain
This one is not directly a speed fix, but it is connected to how seriously Google treats your blog as a whole. A blog running on a custom domain signals more credibility and permanence than a blogspot.com subdomain, and that affects how Google approaches your site in terms of trust and authority. A blog with a custom domain is also easier to verify in third-party tools and to track consistently in Search Console.
Beyond credibility, a custom domain makes it easier to set up proper canonical tags, which prevent duplicate content issues that can indirectly affect performance metrics in Search Console. If you are still on a blogspot.com URL, the post on how to add a custom domain to Blogger for free covers the full process step by step. Getting that sorted out now, before your blog grows significantly, is worth the effort.
Step Ten: Test Again After Every Change
The biggest mistake people make when trying to improve their Blogger speed is making five changes at once and then running one test at the end. When you do that and the score improves, you have no idea which change actually caused the improvement. And when the score does not improve, you have no idea which change might have been making things worse.
Make one change at a time, then run PageSpeed Insights again and record the new score. Yes, this takes longer. But it teaches you what actually matters for your specific blog's setup, and that knowledge is more valuable than the score improvement itself. What hurts a blog with a heavy third-party theme is different from what hurts a blog with a custom lightweight theme. Treat your own blog as the data source and test accordingly.
What a Realistic Blogger Speed Score Looks Like
Let me set honest expectations here, because a lot of posts on this topic promise results that are not realistic for Blogger blogs. Getting a Blogger site to score 100 on PageSpeed mobile is extremely difficult because of things you cannot control: the Blogger platform's own JavaScript, AdSense ad scripts if your blog is monetised, and the way Blogger's default theme rendering works.
A score of 70 to 85 on mobile after implementing the changes in this post is a realistic and genuinely good outcome. On desktop, scores of 85 to 95 are achievable with a lean theme and optimised images. That range puts you comfortably in the territory where speed is not a disadvantage in search rankings and where most visitors will experience your blog as fast and responsive.
Do not get discouraged if you are not hitting 90 on mobile. A 78 with good content, proper structure, and a solid internal linking strategy will outrank a 95 with thin content almost every time. Speed is one ranking factor among many. Getting it from a red score to a green or amber score matters. Chasing perfection beyond that is not the best use of your time as a blogger.
Finally
Improving your Blogger blog's speed is not a one-afternoon job, but it is also not as technically complex as most guides make it sound. The changes that actually move the needle are mostly about discipline rather than technical skill: compress your images before uploading, trim your theme down to what you actually need, load fonts in a way that does not block rendering, and keep your post HTML clean.
The platform itself does some of the heavy lifting for you. Blogger's servers are Google's servers, and Google's infrastructure is fast. What you are doing with these steps is making sure you are not undoing that advantage with code and content choices that create unnecessary weight.
Take the PageSpeed Insights score you have right now, implement the changes in this post one by one, and track what happens. A faster blog ranks better, holds readers longer, and earns more from AdSense because better engaged visitors see more ads. The work you put in here pays off across every part of your blog's performance.
If you are also thinking about how your blog's URL structure and technical setup affect SEO more broadly, the post on removing the date from Blogger post URLs covers another commonly misunderstood area of Blogger technical SEO that is worth reading alongside this one.
