Another recommendation from various website speed tests may be to serve resources, such as JavaScript, CSS, or images, from a consistent URL. After the speed test finishes and you are reviewing the recommendations, you may be notified that some resources are serving up the same content, but different URLs. Obviously, this is redundant and should be fixed. This can happen for several reasons, but more likely if there are multiple people working within a site at various times. If there are too many identical resources served from the same page, it slows down your page load time and is inefficient. Every byte counts and reducing the number of requests and resources is a straightforward way to help get faster page load times.
