JavaScript & CSS: What You Need to Know for SEO

What You Need to Know for SEO: JavaScript & CSS in San Diego, CA

With SEO, technical things are important, too. This doesn’t mean you have to delve into the specifics of website development or common coding languages like CSS and JavaScript. However, it can help to have general knowledge about the basics of these two languages, since related issues could affect how your site performs on search engines. The experts from Saba SEO, specialists in Internet marketing San Diego businesses have relied on for more than fifteen years, explain what you need to know about CSS, JavaScript, and SEO.


Cascading Style Sheets (CSS) are used with HTML. The HTML markup part of this combination sets things up so Google can understand your site and its various elements better. CSS dresses things up and makes what’s presented user-friendly and visually appealing in a way that’s not possible with HTML alone.

CSS’s SEO Impact

Ever since mobile friendliness became a thing for ranking purposes in 2015, Google has been paying more attention to CSS. To correctly lay out pages for smaller screens, CSS code needs to be done properly. CSS helps Google determine if pages are laid out correctly on desktop screens as well. This code also shows where each piece of content is placed.


CSS is essentially window dressing, and JavaScript (JS) is the added finishing touch. What JS does is update website elements in real time to respond to various user actions. JS plays a role in helping with everything from pop-ups and animated graphics to interactive elements. Search engines execute this code to get a full understanding of your site.

JS’s SEO Impact

JavaScript errors can cause Google not to follow links on pages coded with this language. Errors with JS could also result in entire pages of your website not getting indexed at all. Overdoing it with JS, which is a “heavy” type of code, can also affect your rankings. This is because too much JS can slow down page load times and boost bounce rates.

Because of the potential for errors with CSS and JavaScript that could affect user experience and your rankings, it’s important to work with a reputable experienced developer. Part of this process should involve regular testing of the technical elements of your site. What this does is ensure there’s a convenient and pleasant user experience that appeals to your visitors and Google.
