Explanation:
The purpose of 'alt text' in images for SEO is to describe images to search engine crawlers and improve accessibility. Alt text provides a textual alternative to images for web browsers when pictures are loading or if they are not available. This is beneficial for search engines to index and understand the content of the image, aiding in search engine rankings, and it is crucial for users with disabilities who use screen readers to access web content.
When writing alt text, it's important to accurately describe the content or function of the image. This helps improve the user experience for those with visual impairments and also provides context for search engines, which may factor this information into their ranking algorithms. In a scenario where images are not displayed due to loading issues or errors, alt text ensures that the information intended to be conveyed by the images is still accessible.
