Blake is going through a technical SEO audit for his company's website when he notices that several pages are taking 6 or more seconds to load. He knows this is too slow and he needs to speed them up, but isn't sure how to identify what's causing the slowdown or how to fix it. To get started, what should Blake look into?

Page speed issues can stem from multiple sources, including large code files, unoptimized JavaScript, and oversized images or videos. Minifying code reduces file size and speeds up load times. Moving non-essential JavaScript to the footer allows critical content to load first. Compressing media files decreases bandwidth usage and improves user experience and SEO performance. Addressing all these factors optimizes page speed holistically.
