CSS file size too large discovered in SEO audit

When conducting an SEO audit on your site, one issue that might come up is that your CSS file size is too large. But why does this matter, and what can you do about it? Let's dive in.

What's the Issue?

During our audit, we've identified that your website's CSS files exceed the recommended size limit. Specifically, we're talking about CSS files larger than 15kB. This might seem minor, but it's a critical aspect affecting your site's performance.

Why Does It Matter?

The size of your CSS files directly impacts your page load times. In the fast-paced digital world, every second counts. Slow-loading pages can lead to higher bounce rates, decreased user satisfaction, and ultimately lower search engine rankings. Ensuring your CSS files are optimally sized is crucial for maintaining a fast, efficient website that keeps users happy and engaged.

How to Fix It

1. HTTP Compression: First, check if your CSS files are using HTTP compression. This can dramatically reduce the size of your CSS files, making them quicker to load. The most common compression methods are gzip and Deflate. Implementing HTTP compression might require some technical know-how, so it's a good idea to consult with your development team.

2. Minification: CSS files often contain unnecessary characters, such as whitespace, comments, and formatting, which increase file size without serving any functional purpose. Minifying your CSS removes these elements. For smaller sites or less frequent updates, online tools like cssnanoand Minify are perfect. For larger projects or sites undergoing regular updates, consider automating the process with tools like Gulp or Webpack.
