301 Redirect is a HTTP response that permanently sends users and search engines from one URL to another.

Properly configured redirects help preserve relevant search reach, backlinks, and user access during website changes.
404 Error is a HTTP status code showing that a server can't find the resource requested by a browser or search engine. It usually appears when a page has been deleted, moved without a redirect, or entered with an incorrect URL.

The visible area depends on the device, screen size, browser window, zoom level, orientation, and layout. It often contains a page’s primary heading, value proposition, navigation, imagery, or call to action, but its exact boundaries are not fixed.
Alt Text is written text attached to an image in HTML that describes the image’s purpose or meaning. Screen readers can announce this description to people who can't see the image.

It's shaped mainly by crawl capacity, which limits server load, and crawl demand, which reflects site size, freshness, quality, and popularity. Crawl Budget affects discovery, not guaranteed indexing.
Domain Authority is a third-party SEO score that estimates how likely a website is to rank in search results compared with other websites.
