Do you really need that video background loop in above the fold on your website? Have you ever wondered why your homepage has a low page speed score? The huge image or video within the above-the-fold area, or hero section, is likely the culprit. Multiply this by the number of pages with a similar design and factor in that the website is put together with plugins, and you start to get the picture.
