In today's fast-paced digital world, website speed is more important than ever. Not only does it affect user experience, but it also plays a crucial role in search engine optimization. In this comprehensive guide, we'll explore:
Why Website Speed Matters
Google has explicitly stated that page speed is a ranking factor. Here's why it's so important:
