Blogger sites have a natural speed advantage — Google hosts them — yet many still load slowly because of heavy templates, oversized images and gadget overload. Speed matters twice: readers leave slow pages, and Google uses Core Web Vitals as a ranking signal. These nine fixes are ordered by impact, and most take under ten minutes each.
1. Compress Images Before You Upload
Images are the heaviest part of almost every blog page. Convert photos to WebP (or at least optimised JPEG), and resize them to the width your layout actually displays — usually 1200px is plenty for a post image. Uploading a 4000px photo and letting the browser shrink it wastes your readers' data on every visit.
2. Set Inserted Images to Original Size — But Upload the Right Size
Blogger's editor inserts images at a small default size, which then looks blurry when the theme stretches it. Setting the image to Original size fixes the blur — but "original" should mean a sensibly sized file (see fix 1), not a 5 MB camera photo. Right-size first, then insert at original size, and you get sharp and fast.
3. Remove Gadgets You Do Not Need
Every sidebar gadget can add scripts, requests and layout work. Open Layout and delete anything that does not earn its place — old counters, unused social widgets, demo boxes left over from a previous theme. Fewer gadgets also means fewer layout shifts while the page loads.
4. Limit Posts and Widgets on the Homepage
A homepage showing 20 full posts with 20 large images will always be slow. Show a reasonable number of posts (7–10) with thumbnail cards instead of full content, and let readers load more when they want it — that is exactly how the Latest grid on this blog works.
5. Be Careful With Sliders and Animations
Image sliders are the classic speed trap: several large images, a script library, and a layout shift as the first slide loads. If you use one, keep it to three slides with compressed images. If your template offers a static hero instead, take it — your Core Web Vitals will thank you.
6. Avoid Third-Party Script Clutter
Pop-ups, notification bells, floating share bars, auto-playing video widgets — each one is another script your readers' phones must download and run. Add third-party tools one at a time and check your PageSpeed score after each. If a tool is not measurably helping, it is measurably hurting.
7. Choose a Lightweight Template in the First Place
No amount of tuning fully rescues a bloated template. When you pick a design, prefer clean code, minimal built-in scripts and a performance focus — our SEO-Friendly Templates guide covers what to check, and templates like SEO Next are built around Core Web Vitals from the start. If you want the fastest possible setup, look at our AMP Blogger Templates page.
8. Use Lazy Loading Where You Can
Modern browsers support loading="lazy" on images, which delays off-screen images until the reader scrolls to them. Many current templates already include it for post images; if yours does not, adding the attribute to below-the-fold images in your posts is a safe, quick win.
9. Measure With PageSpeed Insights — Mobile First
Test your homepage and one post at PageSpeed Insights and read the mobile report first, because that is the version Google indexes and most readers use. Fix what it flags under "Opportunities" in order, re-test, and write down your scores so you can tell whether a change helped or hurt. Aim for green Core Web Vitals on real posts, not just the homepage.
The Bottom Line
Fast Blogger sites are not an accident: right-sized images, few gadgets, a lean template and regular measuring. Work through this list once and your readers will feel the difference on the very next visit.
