The check used non-existent phrases (basically gibberish) and found that Google couldn’t discover photographs by utilizing greater than 16 phrases to seek for it.

Utilizing gibberish to check Google tends to end in flawed “website positioning check” outcomes.

That’s type of the first use case of the alt textual content.

We do additionally use the alt textual content as part of the web page. However that to me, that’s normally one thing that’s already seen on the web page anyway.

What Phrases to Use in Alt Textual content

Mueller subsequent started explaining how to decide on the perfect phrases for the picture alt textual content.
