What is Cumulative Layout Shift (CLS) and How Does it Affect Your Website's Google Rankings?
In today's digital landscape, it's crucial for businesses to maintain a strong online presence. One of the key factors that can impact your website's visibility and rankings on Google is Cumulative Layout Shift (CLS). This article will dive deep into what CLS is, how it can affect your website's position in Google search results, and how to address and optimize your site for a better user experience.
With the rapid growth of e-commerce and online businesses, search engine optimization (SEO) has become a vital aspect of building and maintaining a successful website. Google, being the most popular search engine, regularly updates its algorithms to ensure that users are provided with the best possible search results. CLS is one such parameter that Google considers when ranking websites.
2. What is CLS?
Cumulative Layout Shift refers to the total layout shifting that occurs during a website's loading process. It occurs when elements on a page move, change position, or shift around while the page is being rendered. This shifting can result in a poor user experience, as it causes unexpected movements and can make it difficult for users to interact with the page.
3. The Impact of CLS on Google Rankings
Google aims to provide users with the best possible user experience. Pages that have a high CLS are considered to offer a suboptimal user experience and may be ranked lower in search results. The goal is to minimize layout shifting and ensure that elements on the page remain stable during loading.
4. How to Determine if Your Site Has a CLS Issue
To determine if your website has a Cumulative Layout Shift issue, you can use tools like Google Speed Insights and Chrome Lighthouse. These tools analyze your website's loading performance and provide insights into any layout shifting problems. By identifying the source of the problem, you can take appropriate steps to fix it.
5. Fixing the CLS Issue
Fixing the CLS issue involves optimizing your website's loading process and minimizing layout shifting. Here are some effective strategies you can implement:
5.1 Using Google Speed Insights
Google Speed Insights is a powerful tool that evaluates your website's performance and provides recommendations for improvement. It can help you identify elements on your website that are causing layout shifts and guide you on how to address them.
5.2 Chrome Lighthouse Tool
The Chrome Lighthouse tool is another excellent resource for analyzing your website's performance. It allows you to view the original trace and identify any moving elements during the initial load. By addressing these elements, you can prevent layout shifting and improve the user experience.
5.3 Lazy Loading CSS
Implementing lazy loading CSS can significantly reduce layout shifting. By loading the theme.css file after the rest of the DOM is downloaded, you can ensure that elements are not displayed unstyled during the initial loading phase. This technique can help eliminate significant layout shifts and enhance the overall user experience.
5.4 Inline Critical CSS
To further minimize layout shifting, it is essential to include inline critical CSS for the visible part of the page. Critical CSS ensures that the page looks good in the first few seconds, even before the theme.css file is downloaded. By reserving space for elements and preventing them from causing shifts, you can create a smoother loading experience.
5.5 Testing and Debugging
After implementing optimization techniques, thorough testing and debugging are necessary to ensure that layout shifts have been successfully mitigated. Use tools like Chrome Lighthouse and Google Speed Insights to identify any remaining issues and fine-tune your implementation accordingly.
5.6 Addressing Elements Below the Fold
Although Google prioritizes above-the-fold content, fixing elements below the fold can also contribute to a better user experience. Reserve space for elements that might cause shifts, even if they may not be immediately visible. By addressing these elements, you ensure a more consistent and seamless page loading experience.
6. Additional Considerations for CLS Optimization
In addition to the strategies mentioned above, there are a few additional considerations for optimizing CLS:
- Consider using conditionals to render CSS rules only on specific templates or pages where layout shifts are occurring.
- Address issues suggested by Google Speed Insights and Google's insights test, preventing elements from shifting or causing other elements to shift.
- Regularly monitor CLS performance and make necessary adjustments to maintain optimal user experience.
- Keep in mind that the Google Search Console may take a couple of days to reflect improvements in CLS performance.
7. Testing and Monitoring CLS Performance
Testing and monitoring the CLS performance of your website is crucial for ongoing optimization. Regularly run tests using tools like Chrome Lighthouse and Google Speed Insights to identify any new layout shifts that may arise and address them promptly. By keeping a close eye on your CLS score, you can ensure that your website remains user-friendly and optimized for search engines.
8. Refreshing Data in Google Search Console
When implementing CLS optimizations, it's important to remember that the Google Search Console may not reflect immediate changes in performance. It may take a couple of days or more for the Console to refresh its data and accurately reflect improvements in CLS score. So, be patient and continue monitoring your website's performance regularly.
9. Creating a CSS Snippet for CLS Prevention
If your theme does not have a critical CSS file, you can create a CSS snippet to address CLS directly. By adding CSS rules that prevent layout shifts to specific templates or pages, you can optimize the loading experience on those particular sections of your website.
Cumulative Layout Shift (CLS) is an important metric to consider when optimizing your website for better search engine rankings and user experience. By understanding the impact of CLS and implementing effective optimization strategies, you can ensure that your website loads smoothly and offers a seamless browsing experience to your visitors.
Remember, it's essential to regularly test and monitor CLS performance, address any new layout shifts promptly, and keep up with best practices to maintain a high-quality user experience on your website.
