Preface: 78 Empirical Problems Record, and 67 Graphics and Source List.
This is a task: to ensure that pictures and videos are readable, correspond to the text and adapt to the page experience.
Objective and readiness
The video is both a content evidence and a technical resource that needs to be managed. Prepares a list of material and experience, matching each resource to the page and purpose, checking the address, file type, display size, description and access status.
Key images should be presented through appropriate img elements and resource addresses, and not just CSS background or drawing a canvas to carry products and technical information. The alternative text describes the actual object and use, and does not insert irrelevant keywords. The file name, abbreviation and the surrounding text are consistent, and a picture from a normal scene material cannot be marked as a record of a real customer test in a technical configuration.
Method of operation
The main picture on the front screen, especially the LCP element, should not be mechanically delayed; the next picture can be loaded with appropriate latency, but only to ensure that it is readable and does not depend on a special user click to generate resources.
Video checks whether the player, thumbnail and related address are stable and can be actually viewed. If the business wants to gain access to the video search function, you should further confirm the page and the conditions for viewing a single video.
Apply examples
For example, a technical article on a plastic parts factory should be used, with a picture showing the structure of the component, and the text indicating which interface information the request for a price requires to be checked. The photograph must be clear and complete, and the picture description cannot extrapolate unknown specifications.
Externally hosted pictures and players also need to check resource access, paying particular attention to invalid authorized addresses, over-expired links, and wrong blockages. The publisher should verify on the actual page that the cell phone displays and loads errors, and the video is removed or set in camera.
Outputs and acceptances
A search tool can help to check resource discovery or video status, but technical conditions do not necessarily mean that it will be displayed. You cannot write a single message to the entire media directory to save the address, screenshot and results of the detected problem.
The next structured data can only use this confirmed information and not fill out the viewer's address as a video file address. The exact content supports the SEO page with a stable resource, and compression and tagging are specific measures to serve this goal.
