When search engines first launched, they only displayed plain text descriptions with a link, but today, they have a wide variety of formats. Understanding how to get included within the SERPs features is super-important to attracting organic search visits today.
The increasing importance of rich organic SERPs features aside from text are suggested by this regular updated features analysis by Moz which shows the importance of related questions, local information, images and videos.
The importance of different features varies by sector, so you should check these out for your sector. This example from the Laser eye treatment sector shows that local results, related questions and video explainers can be important.
