4/8 HTML tags SEO - Picture SEO (HTML alt tag SEO) - important HTML tags involved in SEO optimization

 HTML tags SEO -  Picture SEO (HTML alt tag SEO): The main goal of alt text for images is accessibility, while the SEO goal of alt attributes is image indexing.

The main goal of image substitute text is to help users understand the image. For example, some people in the same picture understand different meanings. Adding the image substitute text makes it easier for users to understand the meaning of the original author. There is another situation, that is, when the web page loads slowly, or some other reasons occur that make it impossible to load the image, you can use alternative text to describe the content in the image instead of viewing the image.

From an SEO point of view, search engines cannot recognize the content of images by themselves. Alternative text is an important part of how to index images in Google search. Therefore, if your work has visual elements-whether it's product images, works, stock images or artwork, then you should definitely consider using images instead of text.

Picture ALT SEO considerations

The prerequisite for adding an alt text tag is to find all images without it.

You can use tools like WebSite Auditor to crawl your website and compile a list of images with alternate text. To

Be concise, but descriptive - the alternate text should be one or two lines of text so that people can understand the content of the picture.

Don't be too succinct - one word or several words may not be able to make people understand better or even distinguish the image from other images. Consider all possible attributes of the display: object type, color, material, shape, finish, lighting, etc.

Don’t deliberately do keyword stuffing - SEO optimization of pictures only focuses on the description of the content of the picture. This is the key point. Don’t deliberately add keywords to the picture in order to optimize a certain keyword. It would be better if keywords can be naturally integrated into the description of the picture.
