SEO Romeo and Juliet Introduction: What should we pay attention to in image optimization in website SEO?

1. The content of the website comes first, don’t use pictures

Search engines can already perform simple recognition of the content of images, but search engines are unable to recognize the content in most images. For navigation or important locations on a web page, it is recommended to use text to describe them instead of using pictures.

2. Reasonable use of ALT tags
The alt tag refers to the descriptive label of the image. Simply put, it is the product description on the box when we buy a product. When search engines judge the content of images, they will mainly refer to the content in the alt tag. The alt tag is usually added inside the tag.

When using the alt tag, describe the image. Do not write content that is irrelevant to the image, or directly stuff keywords.

3. The text near the website pictures should be detailed. The text around the picture (picture context) will affect the search engine's judgment of the picture. We recommend that the text and images be relevant. For example, if you put a picture of a tractor in a description of how to cook delicious food, it would be difficult for people to understand. In addition, another important place is the title of the article.

4. The image pixels and size should be moderate. The higher the image pixels, the clearer it is. The SEO forum recommends that each image should not be larger than 200K. If the image size is too large, it will affect the loading time of the website. This results in a poor user experience. In addition, the picture size should be appropriate, with a ratio of four to three.
