Question: What is minification?
- The process of reducing resource size by removing unnecessary comments and spacing in the source code
- The process of replacing repetitive pieces of code with markers directing to the first instance of that code
- The process of redirecting large groups of URLs in batches during a site move
- The process of moving large JavaScript files to the bottom of a page for all non-essential functions
Explanation
Minification reduces the size of code files by removing unnecessary whitespace, comments, and formatting. This decreases download size, improves page load speed, and enhances user experience. Smaller, optimized files help search engines crawl pages more efficiently and support better Core Web Vitals performance. Minification is a standard technical SEO optimization for HTML, CSS, and JavaScript.
Why the other options are incorrect
B) Replacing repetitive code with markers is code refactoring, not minification.
C) Redirecting URLs relates to site migrations, not code optimization.
D) Moving JavaScript affects render order, not file size reduction.
