24 Useful CSS Rules For SEO

1. Make External CSS Files

While inline CSS is handy and easier for small projects, making external stylesheets is always a good practice. It is because search engines look at the code of your page, so the less clumsy the CSS code, the better search engines will perceive the content.

2. Add Responsive CSS Code Snippets

Just to let you know, more than half of a website’s traffic comes from mobile devices. It means your websites must be responsive and retain the same design even if viewed from different devices. CSS not only ensures styling but also helps to make your website more responsive.

3. Add CSS To Semantic Markup

HTML Semantic Markups, such as <nav> <header>, help search engine bots understand your content’s different sections. With concise CSS, you can not only increase the readability of various segments but can reduce the usage of HTML elements, ensuring lightweight code, a faster website, and improved search engine results.

4. Avoid Certain Code Practices To Optimize Page Load Speed

CSS codes can be written in many different ways. For example:

Avoid making your CSS codes too fancy because if the search engine crawlers face issues in parsing your code, this might decrease your website’s acceptability, even resulting in a decrease in your content rankings.

CSS minification can help you reduce the unnecessary block delimiters, line breaks, and whitespaces of your website’s CSS code, thereby reducing file size and promoting better loading and search engine results.
