The key to the topic is not to find a fixed value. The real reusable judgement is that the alternative text should be a simple description of the content of the picture and its role in the article.
The signal that really needs to be diagnosed is “AlT cannot help understand photo information if it has a stack of keywords or duplicate titles.” Before expanding production, a full selection should be checked to the transformation chain.
From an official note, some common misunderstandings can be excluded. VideoObject should describe the real and visible video on the page.
In order for YouTube to be available again, the project records should include the target market, the material version, the release time and four check points: IMAGE, MEANING, ALT, ACCESS.
Do not copy in bulk immediately. Select a representative scene to complete the sample, confirm that there are no questions of fact and authority, by " describing the chart object, key relationships or interface steps, without writing decorations, and leaving a blank on a pure decorative map " .
A flash drive cannot stop at the total playload. Apply the reading screen order and the picture closes the scene to check if the article is still understandable and then to match the change to a specific image, source or page action.
Search optimization does not duplicate words such as “youtube operations”. Natural writing of brands, products, areas, roles and problems is more conducive to establishing physical relationships than stacking keywords.
Pre-production may be preceded by a list of “must” and “not”. The former includes key evidence and limitations, while the latter includes customer privacy, unauthorized assets and unproven commitments.
The content requires a complete service task. If the user is to compare, install, type or request, the page should provide the information necessary to perform the task, rather than deliberately breaking the answer.
The same term may be used in different markets for different products or buying habits.
You also have to calculate the long-term cost. Copying the list of keywords in the ALT reduces accessibility and has no real semantics. The number of views exchanged with the wrong expectations is not equal to effective growth.
