Sustainable SEO: What Is It and How to Achieve It?

Most industries are giving greater consideration to reducing their environmental impact, but as consumers, we often forget one of the sectors that requires the most energy consumption, simply because it is intangible: the internet. Can a lower energy-consuming internet be built from our position? How can we do it without harming our rankings and visibility? This is what the concept of sustainable SEO is about.

The fact that the internet requires energy to function is no surprise. However, what has started to alarm governments, companies, NGOs, and users is the sheer amount of energy consumed with every search, download, or social media activity. According to a study conducted by McMaster University in Canada, in 2018, the Information and Communication Technologies (ICT) sector consumed between 6% and 10% of the global electricity generated. The outlook for 2030 is even more concerning: this percentage is expected to climb to 21%.

This information has become crucial for most large companies, but small websites can also contribute to change. From this premise, sustainable SEO was born.

Guidelines for Implementing Sustainable SEO on Your Website

Sustainable SEO, to varying degrees, can be applied to all websites. To achieve this, there are certain best practices commonly found in most energy-efficient websites:

• Image Optimization: Reducing web loading times is essential, and images are among the elements that consume the most energy. Therefore, it is recommended to compress them and ensure that each image is appropriately sized for the chosen web format and final device. Additionally, choose the right format for each image (JPEG, PNG, WebP).
• Eco-Friendly Hosting: As a web developer, you can look for hosting providers that use renewable energy and have environmental certifications like ISO 14001.
• Clear Structure: Short and descriptive URLs are advised.
• Minimize Redirects: Each redirect increases the time it takes for a web page to load. For this reason, only implement redirects that are strictly necessary.
• Publish Relevant Content: Sharing duplicate or redundant content not only risks penalties but also results in unnecessary energy consumption. Instead, consider updating already published content or changing the topic altogether.
• Responsible Email Marketing: If you run email marketing campaigns, review your actions to avoid spam or excessive emails. Segment your audience and reduce the number of emails sent. This not only helps the planet but also prevents audience fatigue.

Examples of Low-Energy Websites

Eco-friendly SEO is already present on many business websites. Some success stories include:

• Treehugger: This eco-content site aligns with sustainable SEO requirements by using compressed images, a simple web design, and reducing overall page weight.
• GreenGeeks: This hosting company not only offers eco-friendly services but also applies sustainable SEO practices on its own website to rank for “green hosting.”
• Organic Basics: The organic and sustainable clothing retailer significantly reduces its website’s loading time.
• WWF (World Wildlife Fund): The Swiss NGO also strives to reduce its website’s carbon footprint. They maintain a minimalist design focused on key news to minimize energy consumption without sacrificing impact.

Is the Future of the Internet Eco-Friendly?

Recently, one of the central debates has been the future of technology and the next big steps online. Although much of the conversation revolves around new services or products, one characteristic must be present in any projection we make: it will be eco-friendly.

In almost every sector—energy, industry, architecture, food, and many others—there is a clear trend toward resource sustainability, and the internet will be no exception. Both companies and individuals are becoming increasingly aware of the importance of preserving the environment, and we will see ecology playing a more prominent role in launching products, services, or websites.

Although energy waste statistics are alarming, the good news is that everyone can contribute in their own way and gradually create a sustainable online ecosystem.
