Image optimization plays an important role in SEO
Beautiful images can make users look pleasing to the eye and add beauty. If the website has a large number of images, and these images have not been optimized, it will affect the collection and ranking of search engines, and will also lose a lot of traffic.
Search engines can only recognize text content, and some non-text content cannot be recognized, including pictures and flash. It is difficult for search engines to capture the content of images, even images relevant to the website.
If you have a lot of images on your website, you need to optimize the images accordingly. The easiest way is to add the ALT attribute to the image, that is, name the image and tell search engines what the image is about, so that search engines can identify the content of the image.
The benefits of image optimization
- The search engine can well identify the content of the picture, which is easy to crawl, which is conducive to finding the corresponding picture in the picture search and brings more traffic to the website.
In addition to being able to find images in image searches, if they contain popular keywords, they can also appear in search engine search results, which can also increase website traffic.
- Keywords can be added to the ALT attribute of the picture, which can increase the keyword density and help improve the keyword ranking.
2. Which images need to be optimized in the website
The pictures in the website do not need to be optimized for the website, as long as the important pictures are optimized so that the search engines can identify and crawl them.
