Alt tags (also known as “alt attributes” and “alt descriptions”) are HTML attributes applied to image tags to provide alternative text for search engines. Applying images to alt tags such as product photos can have a positive impact on the search engine ranking of e-commerce stores.
What does the alt tag do? Search engines and other robots cannot interpret images, but images can play a key role in people’s interpretation of specific web pages. Alt tags solve this problem by providing text read by search engines. When Googlebot or other search engine crawlers check the page, images with properly formatted alternative text will help the page build index and rank on the page.
