Panda was able to determine which elements of a page were visible, invisible, had text that matched the color of the background, and more.
It can be tempting for a web designer to include many cool elements on a website like fancy slideshows, or “lazy-loading” some elements as the user scrolls down the page, but this client-side rendering is really impacting SEO in a negative way. It used to be that Google, and other search engines, had no way to know which elements on a website were visible or invisible.
