Common Questions About HubSpot Performance & Rebuilds
Can a HubSpot website rebuild fix Core Web Vitals issues?
Yes—when Core Web Vitals issues stem from theme architecture, legacy markup, or script bloat, a rebuild is often the most effective solution. In this project, rebuilding the site resolved all mobile CWV issues and moved every affected URL from “Poor” to “Good” in Google Search Console.
Why is my HubSpot website failing Core Web Vitals on mobile?
Most mobile CWV failures are caused by unoptimized themes, heavy third-party scripts, oversized media, and layouts that weren’t built with modern performance standards in mind. Mobile users are more sensitive to these issues, which is why problems often appear there first.
Is it better to rebuild a HubSpot site or optimize the existing theme?
If performance issues are isolated, optimization may be enough—but when problems are widespread across templates and pages, a rebuild is usually faster and more reliable long term. A rebuild allows performance, accessibility, and editor experience to be addressed at the foundation instead of patching symptoms.
Can improving Core Web Vitals also improve SEO and AI visibility?
Yes. Passing Core Web Vitals improves crawl efficiency, user engagement signals, and eligibility for modern search features, which can positively impact SEO. Faster, cleaner pages also make it easier for search engines and AI systems to extract, summarize, and trust your content.
