I believe that the importance of the ALT attribute of images goes without saying to every SEOer, but some beginners are a little confused about this - what is the role of the ALT attribute of images? How to write it? Let me first talk about what is the image ALT attribute. The so-called image ALT attribute is the text that describes the image. The description text will not be displayed on the page, but will be displayed when we place the cursor over the image. Then there is its importance. When our network speed is too slow, the picture will not be displayed. The ALT attribute of the picture will show the content of the location to the visitor, which increases the user experience. The most important thing is to add the website's content in the description. Keywords can increase the keyword density of a website. When search engines crawl the page, the description of the image can also better help the search engine understand the image, which is beneficial to the ranking of the website. The ALT attributes of images are beneficial to both search engine crawling and user experience, so we must pay attention to the ALT attributes of images. Let’s give an example to specifically explain how to write the ALT attribute of an image.
If we make a picture of a 17.5-meter light special semi-trailer, I. Low-bed semi-trailer, warehouse-rail semi-trailer, light special semi-trailer, compartment-type semi-trailer; II. Light special semi-trailer; III. 17.5-meter light special semi-trailer in gooseneck Double-layer reinforcement is carried out on the axle and axle. From these three options, the description of III is the best. I just piles up keywords, which may be considered by search engines as blackhat cheating. II is just a keyword, which is slightly better, but does not describe the model, structure, etc., and the user experience is slightly worse. By correctly writing image ALT instead of attributes, it can help the website obtain a good keyword ranking, so SEOers must pay attention to this.
