As the marketer for TravelTheWorld.com, the user experience for the site is Harper's responsibility. She enjoys creating rich, impressive content that creates a welcoming environment for users. But the slow performance of the site frustrates her. What's a factor that's likely slowing down the performance of the website?

Analysis of Correct Answer(s)

• Videos: This is the correct answer because the prompt mentions Harper creates "rich, impressive content." Videos are a prime example of rich media. They are typically very large files that significantly increase the overall page weight and load time. Without proper optimization techniques, such as compression, lazy loading (loading the video only when it's visible to the user), or hosting on a dedicated platform, videos are a common and major contributor to slow website performance.

Analysis of Incorrect Options

• Coding errors: While poorly optimized code can slow down a website, "coding errors" more often lead to broken functionality rather than just slow performance. It's a less direct cause compared to the definite impact of large media files.
• Localization: This is the practice of adapting a website for different languages and regions. When implemented correctly, often using a Content Delivery Network (CDN), localization can actually improve performance for international users by serving content from a closer server. It is not an inherent cause of slowness.
• HTML: This is the standard markup language for creating web pages. HTML files are typically very small and lightweight. While inefficient HTML can slightly impact render time, it is rarely the primary reason for a significant performance slowdown, especially when compared to heavy assets like videos.
