The seasoned digital marketers use the appropriate image compression tools to minimize the file size without sacrificing image quality by adjusting the resolution percentage.

But Google requires digital marketers to create and add structured data following a set of guidelines. The experienced digital marketers leverage popular SEO tools like Yoast to add structured data to images without putting in extra time and effort.

However, they do not create separate image sitemaps when the website is small and simple.
Unlike static images, responsive images are adjusted or customized automatically according to the size of the screen. The smarter digital marketers make images responsive using CSS. The CSS code scales up or scales down the original images based on the values of specific attributes – height, width, and max-width. However, some web browsers and search engine crawlers do not understand these attributes. Hence, the digital marketers still deliver images using the src or source attribute of the IMG tag.

They allow digital marketers to change the image format and customize the image loading process based on present conditions. The smarter digital marketers leverage image CDNs to boost user experience by accelerating image delivery.
