SEO teams are increasingly treating sustainability as a measurable part of performance. In 2024, 63% of marketers planned to increase sustainability related spending, and 79% of organizations said SEO or SEM matters to their marketing strategy. At the same time, 40% of websites have at least one major accessibility issue, and third-party scripts add page weight that increases bandwidth and CPU use during rendering.
Key Takeaways
- 79% of organizations consider SEO/SEM important to their marketing strategy in 2024
- 40% of websites have at least one major accessibility issue (WebAIM Million, 2024)
- 72% of organizations reported using data-driven marketing analytics in 2024
- Energy efficiency improvements in data centers are expected to offset growth: global data center energy consumption is projected to reach 620–1,000 TWh by 2030 (IEA projection range)
- Most of the web’s resource requests are from third parties; reducing third-party scripts can directly reduce bandwidth and CPU costs (HTTP Archive analysis)
- Global digital advertising energy use is materially driven by data centers and networks; IEA estimates ICT energy use share around 1% of global electricity in 2020
- US$34.5 billion was the estimated global market size for green data center solutions in 2023
- The global green building materials market reached US$404.5 billion in 2022
- US$3.3 billion global market size for sustainable web design tools/services in 2023 (estimated)
- Google’s PageSpeed Insights scores are based on mobile performance of real-world data and lab simulations (Lighthouse/PageSpeed documentation)
- Core Web Vitals threshold: CLS should be ≤ 0.1 to be considered 'Good' (2024)
- 14.7% of pages in mobile lab tests had JavaScript execution times exceeding best-practice budgets in 2023 (study) — JavaScript bloat increases client energy use during rendering and can be targeted for greener SEO
- 68% of websites use third-party analytics/trackers that increase page weight (2023 audit benchmark) — suggests third-party management as a key lever for reducing SEO page environmental impact
SEO supports sustainability goals, but greener rankings require fixing accessibility, JS bloat, and third party overload.
