How to Improve Blogger Website Speed

Blogger handles hosting for you, so your control over speed comes from what you put on the page: the template, images, widgets and scripts. The goal is to change those in order of impact and to measure after each change.

Measure before you change anything

Run your homepage and one typical post through PageSpeed Insights. Note the field data section if it appears, because it reflects real visitors, and the lab results, which help you find specific problems. Record the starting numbers so you can tell whether a change actually helped.

Google’s Core Web Vitals targets are a useful goal: Largest Contentful Paint of 2.5 seconds or less, Interaction to Next Paint of 200 milliseconds or less, and Cumulative Layout Shift of 0.1 or less.

1. Fix images first

Images are often the largest files on a page.

Resize images to the size they are displayed at. A 4000-pixel photo shown in a 800-pixel column wastes bandwidth.
Compress them before uploading, and prefer modern formats such as WebP where your workflow allows it.
Make sure images below the first screen load lazily, and that the main image near the top does not.
Give images fixed dimensions so the page does not jump while they load.

2. Remove widgets you do not need

Every widget can add markup, scripts or network requests. Open Layout and remove widgets that visitors do not use, such as old badges, counters and duplicated lists.

3. Reduce third-party scripts

Ads, social embeds, chat tools and analytics scripts can slow a page and delay interaction. Keep only what you can justify, and load optional scripts after the main content where the provider allows it.

4. Limit fonts

Each font family and weight is another download. Use one or two families and only the weights you use. System fonts are the fastest option.

5. Choose a lightweight template

A template with heavy sliders, large icon libraries or many scripts will limit how fast the site can get. When comparing templates, test their demos with the same tools you use on your own site.

Re-test and repeat

After each change, run the same pages again and compare with your baseline. Lab scores vary slightly from run to run, so look for consistent improvement rather than a single number. Speed work does not guarantee a ranking change, but a faster page is better for readers.
