Google Services Images
Web Crawling: Google constantly crawls the web, indexing pages and their content. This includes images found on websites. When it encounters an image, it collects information like the image file, alt text (if available), surrounding text, and the webpage it’s on.
Indexing: All the collected data gets stored in Google’s index, where it’s organized and made searchable. This index contains information about the images, such as keywords, file names, alt text, and the web pages they’re associated with.
Algorithmic Processing: When a user performs an image search, Google’s algorithms swing into action. These algorithms use various factors to decide which images to display and in what order. They consider relevance, quality, and the context of the images. Relevance involves how closely the image matches the search query, while quality relates to factors like image resolution, size, and original source credibility.
Display: Google then displays the images it deems most relevant and high-quality on the search results page. Users can click on an image to view more details or visit the website hosting the image.
