Scope: HubSpot SEO – Reduce Page Layout Shifts (CLS Optimization)

1. Audit & Identification

• Conduct a full audit of HubSpot website pages to detect layout shifts
• Measure Cumulative Layout Shift (CLS) scores using Google PageSpeed Insights, Lighthouse, and HubSpot SEO tools
• Identify elements causing shifts, such as images, fonts, ads, and dynamic content

2. Analysis & Strategy

• Categorize layout-shifting elements based on impact and page priority
• Develop a strategy to stabilize content loading and minimize unexpected shifts
• Prioritize fixes for high-traffic and high-conversion pages

3. Implementation & Optimization

• Specify dimensions for images and videos to prevent resizing during load
• Preload web fonts and implement font-display strategies to avoid invisible text flashes
• Reserve space for dynamic content such as ads, embeds, and interactive elements
• Minimize asynchronous content injections that alter layout after initial render
• Optimize HubSpot templates and modules to ensure stable rendering

4. Technical Verification

• Re-measure CLS scores after optimizations to confirm improvements
• Test across multiple devices, browsers, and screen sizes to ensure consistency
• Validate HubSpot CMS pages for responsive and stable layouts

5. Monitoring & Reporting

• Continuously monitor CLS scores and overall Core Web Vitals in HubSpot SEO dashboards
• Provide regular reports on layout stability, user experience improvements, and search ranking impact
• Identify future content or template changes that could introduce layout shifts

6. Continuous Improvement

• Establish best practices for image sizing, font handling, and dynamic content placement in HubSpot
• Train content and development teams to maintain CLS-friendly pages
• Periodically audit new pages and updates to ensure minimal layout shifts

Outcome:
