Introduction
With every iteration of Google’s algorithm, website performance becomes more than just a technical goal, it becomes a measurable competitive advantage. For businesses operating on Shopify, compliance with data protection laws and maintaining high performance are equally critical. Core Web Vitals, introduced as a ranking factor in Google’s algorithm, are now a central metric in understanding how users perceive loading speed, responsiveness, and visual stability.
The June 2025 edition of Google’s Core Web Vitals Technology Report provides actual user data on how 23 Consent Management Platforms (CMPs), all officially listed by Google, perform across mobile devices. In this article, we review and analyze Pandectes’ position in this report, highlighting where it excels in metrics such as Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Interaction to Next Paint (INP).
For Shopify merchants, these findings are not just insightful, but actionable. Pandectes has positioned itself as a high-performing, user-friendly, and technically sound CMP, built specifically to meet the performance expectations of modern eCommerce.
What Is Google’s Core Web Vitals Report?
Google’s Core Web Vitals report, sourced from the Chrome User Experience Report (CrUX), compiles real-world experience metrics from actual users interacting with websites. These metrics are used by Google Search to assess site quality and shape search results. The report offers valuable insights into how technologies such as CMPs affect loading speed, input delay, and layout stability.
The three core web vitals are:
- Largest Contentful Paint (LCP): Measures perceived loading speed. A good LCP score is below 2.5 seconds.
- Cumulative Layout Shift (CLS): Measures visual stability. A low CLS score (< 0.1) indicates stable page rendering.
- Interaction to Next Paint (INP): INP evaluates responsiveness by measuring input delay. Replacing First Input Delay (FID), it reflects how users perceive responsiveness in a real world experience.
These core web vitals scores are tracked directly by Google and influence how websites are prioritized in search results. Google’s announcement about using these metrics as a ranking factor has placed greater importance on delivering a fast, visually stable, and responsive site.

Visual Summary: Top Core Web Vitals Scores
This chart, based on data from the June 2025 Core Web Vitals report, illustrates the top 10 Consent Management Platforms by percentage of origins passing all three Core Web Vitals thresholds. As shown, Pandectes ranks among the highest-performing CMPs, outperforming several larger competitors. This reflects the platform’s engineering focus on minimizing layout shifts, reducing input delay, and ensuring fast loading even on mobile devices.
How Pandectes Compares to Leading CMPs
To better understand how Pandectes stacks up against established CMPs, the table below compares actual user data from the Core Web Vitals report for June 2025. While Cookiebot, OneTrust, and Complianz are widely adopted in both enterprise and mid-market contexts, their impact on site performance can be significant, especially on Shopify stores where agility, speed, and seamless user experience directly influence conversion rates.
Pandectes leads across the most critical Core Web Vitals metrics, including Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Time to First Byte (TTFB). These metrics are especially vital for Shopify merchants because they affect how quickly a user sees content, how stable the page feels during loading, and how responsive the server is to requests.
Where competitors like OneTrust and Cookiebot often introduce layout shifts and slower load times due to heavy JavaScript bundles and non-optimized content delivery, Pandectes ensures its scripts are asynchronous, lightweight in visual impact, and tailored for Shopify’s front-end framework. Complianz, while performing reasonably well in interaction metrics like INP, lags behind in LCP and TTFB, both of which are fundamental for maintaining fast Shopify storefronts.
In concrete terms, Shopify stores using Pandectes enjoy higher Google Search Console performance scores, fewer CWV-related warnings, and better rankings for mobile-first indexing. These advantages directly translate into improved website’s visibility, faster page loads, and more satisfying content experiences for shoppers.
The following table presents a side-by-side comparison based on actual user data:
Metric | Pandectes | Cookiebot | OneTrust | Complianz |
% Good CWV | 73.28% | 52.36% | 40.05% | 42.13% |
INP | 87.01% | 87.13% | 67.88% | 90.85% |
LCP | 85.82% | 65.30% | 63.03% | 50.28% |
CLS | 90.67% | 79.57% | 72.43% | 81.97% |
FCP | 88.30% | 60.89% | 58.88% | 39.69% |

What Core Web Vitals Mean for Your Shopify Business
The core web vitals scores your site achieves do more than affect metrics, they impact real user experiences and the website’s visibility in search results. Pages with good LCP scores load faster and are more likely to retain visitors. Sites with low CLS keep users oriented and prevent interaction frustration. Low input delay ensures users perceive your site as responsive.
This is especially important for Shopify stores relying on quick decision-making, mobile-first experiences, and fast product exploration. Slow or unstable pages may suffer ranking penalties and lower conversion rates.
Pandectes is built to meet the performance expectations of modern Shopify businesses, helping sites pass Google’s algorithm checks while maintaining compliance.
Impact on Search Rankings and SEO
Google has officially confirmed Core Web Vitals as a ranking factor. Poor scores can result in ranking penalties, especially when better-performing competitors target the same search queries. In contrast, strong scores can reinforce a website’s visibility and trustworthiness in search results.
By using Pandectes, Shopify merchants can meet the performance thresholds recommended in Google Search Console and avoid common performance issues associated with heavier CMPs.
Lighthouse Score and JavaScript Weight
In addition to core web vitals, Google’s Pagespeed Insights and Lighthouse tools provide performance data based on simulated load conditions.
Pandectes achieved the following:
Metric | Value |
|---|---|
