Cache Busting

🛠️ What is Cache Busting?

Cache busting is a technique used in web development to update files in the browser's cache by changing their names or parameters. This ensures users get the most recent version of the file without needing to clear their caches manually.

⭐ Why is Cache Busting Important for SEO?

Cache busting is crucial for maintaining optimal site performance and user experience. It ensures that users and search engines access the latest version of your site, which can positively impact your search engine rankings.

⚙️ How Does Cache Busting Work?

1. A file on your site, such as a CSS or JavaScript file, is updated.
2. A cache-busting technique appends a version parameter or changes the filename.
3. The new parameter or filename signals browsers to load the updated file.
4. Users access the latest version without manually clearing the cache.

📌 Examples of Cache Busting

• Appending a query string like 'style.css?v=2.0' when updating a CSS file.
• Renaming 'app.js' to 'app-2023.js' to ensure users load the latest script.
• Using server-side logic to update file paths automatically upon deployment.
