Beyond that, naming things with human-friendly names, rather than “DSC1352.JPEG”, will help search engines and assistive technology see that image and understand what it is. It’s also important to put images on the page with more detail in context. You want to enlighten the user with some extra content, give them a sense of what’s going on, or give them more context about what you’re talking about. Add information like images, not just to show up in a Google image search.
Video is a little different. It's a series of changing images. So I always say to myself, "How can I make sure that the user can pause the video when they have a thought?"
When we talk about ease of use and providing a great russia mobile database video player experience for any user, having clear playback controls is essential. We talked about images having text alternatives. Videos need text alternatives, too, but they need to be in sync with the video. Otherwise, they will be meaningless in the context of the information.
The same thing is true between video and audio. We think of foreground and background as being easily distinguishable. If your video feels blurry, if your audio feels muddy and requires me to strain my ears or strain my eyes to see what's going on, then you need to be a little bit clearer and make it clearer to understand those two things.
And then there's the transcript. Just like you need closed captions for video, you need a transcript for audio, and let's say I'm in a place where it's really loud, so I can't hear the audio, and if I don't have headphones plugged in, I need to use assistive technology to hear the audio.
These are all things you need to pay attention to when reviewing code as a technical SEO.
