Let’s be honest, pages that load too slowly are incredibly annoying. In fact, Google research indicates that 53% of users will abandon a page that takes more than three seconds to load.
Because of this, any e-commerce SEO agency specialist tasked with optimizing site performance needs to focus on page loading speed as one of the key elements that can improve an organization’s return on their SEO investment.
Why Speed Matters to Search Engines
Site speed is one of the core benchmarks Google and other search engines use to rank search engine results. This is because:
- More users stay on faster sites for longer, which signals to search engines that they find the site trustworthy and valuable.
- Search engines can crawl and index fast sites more efficiently. If your site is slow, the crawler may not be able to process your content correctly.
- Fast-loading sites reduce bounce rates and provide a more valuable user experience.

Every Second Counts
E-commerce is a highly competitive industry. A site can be elegantly designed, but if it is too slow, it may give the impression of being out of date, unprofessional, and/or untrustworthy.
Site speed not only builds trust with visitors, it can also lead to more conversions; this is especially important for mobile traffic. These users may have limited bandwidth and will get impatient if pages don’t load quickly.
To help evaluate site speed, Google offers three Core Web Vitals metrics that can help pinpoint an issue impacting your search engine results, including:
- Largest Contentful Paint (LCP) measures loading performance. It’s best to have an LCP score of less than 2.5; more than four seconds is a problem.
- Interaction to Next Paint (INP) measures responsiveness. The goal is to have an INP of less than 200 milliseconds.
- Cumulative Layout Shift (CLS) measures visual stability. A site should have a CLS score below 0.1.

Underestimating the importance of site speed is one of the most common e-commerce SEO mistakes, despite its direct impact on the bottom line.
How Speed Improvements Translate Into Real Results
At High Voltage, we’ve seen firsthand how site speed improvements can unlock stronger SEO performance and revenue growth. In one case, while working with Intersport, optimizing site structure and performance across a large catalog helped improve crawl efficiency and user engagement. As pages became faster and easier to navigate, the site experienced sustained traffic growth, eventually reaching nearly 200,000 monthly visits.
Speed also plays a critical role in supporting content performance. For example, in our work with FreshBooks, technical optimizations, including improvements to page load times, helped ensure that newly developed content could perform at its full potential. This contributed to scaling organic traffic from approximately 225,000 to 2.5 million monthly visits.
These examples highlight an important connection. Even the strongest content and keyword strategies can underperform if technical barriers like slow load times are in place. By improving site speed, businesses create a stronger foundation for search engines to crawl content efficiently and for users to engage without friction.
When performance, content, and technical SEO work together, the return on SEO investment becomes significantly more measurable and scalable.
