Search engines are able to recognize the existence of their images and their size on websites, blogs, and more. But they are not able to interpret images. When the search engine crawlers arrive at an image, crawler save the image URL with match the tag. Crawlers lack visual perceptions of images and for this reason they can not to recognize what is the subject of that picture. For this purpose, search engines are able to categorize and index images using the attributes defined for images.
"alt" attribute is used to introduce the text of image descriptor in the <img> tag. When the search engine spiders arrive at this tag, with using the filename and "alt" tag, they notice the subject of the image. Then, if someone searches for a phrase matching the "alt" attribute, the corresponding image will also be displayed in the search results.
The page load speed is one of the main factors in the search engine ranking algorithm, thus optimizing site images can be effective in ranking the site. Image file size is in direct communication with image quality and Image resolution. Never use programming commands to resize a photo. You can use software such as Photoshop.
One of the benefits of optimizing images is the ability to display them in search engine search results and attract visitors. The criterion in the Ava Web is quality, not quantity.
