How can I reduce the impact of third-party scripts on my site's performance?
Asked on Feb 21, 2026
Answer
Reducing the impact of third-party scripts is crucial for improving site performance, as these scripts can significantly delay loading times and affect Core Web Vitals. Strategies include deferring non-essential scripts and using asynchronous loading.
<!-- BEGIN COPY / PASTE -->
<script src="https://example.com/script.js" async></script>
<!-- END COPY / PASTE -->Additional Comment:
- Use "async" to load scripts without blocking the page rendering.
- Consider "defer" for scripts that need to execute after the document is parsed.
- Evaluate the necessity of each third-party script and remove any that are not critical.
- Use a tag manager to control and load third-party scripts more efficiently.
- Monitor and audit third-party scripts regularly to ensure they do not degrade performance.
