Many people do website SEO optimization, will put too much energy on the chain website content optimization, website code optimization, website link optimization and other aspects, but found that the picture is not seriously optimized. For websites, the capacity of images not only affects the loading speed, switching speed, response speed, reading comfort and browsing experience, but also has a very important impact on the crawling and crawling of engine spiders. Today, I'd like to explain how to optimize the website pictures!
1. The originality of pictures is very important
Plagiarism is a thing everyone despises, so does search engines. Many people do optimization, only stay in the original text, not enough attention to the original degree of the picture, casually find a piece on the top, but the actual weight of the website is not helpful. Original pictures can get more attention and value recognition. Whether it is to optimize the content of the website or to optimize the website pictures, the original things are more likely to make the search engine fall in love with your website. Use the website building treasure box self-help website building tool to build an original website belonging to you, so that the search engine will like you more.

If you do this for a long time, the weight of the website will be lost.
4 add ALT and title tags
ALT tag is too important. Engine spiders rely on this to judge pictures. Although engine spiders are becoming more and more intelligent, it still needs some time to develop from 100% accurate and complete recognition of images and flash content. And the title tag is often forgotten by SEO people, what is this? It is for the browser to see, when the mouse can be displayed. It can be said that ALT and title tags are language tags for engine and viewer to recognize image content, which are very important.
5. The principle of less use of three pictures
That is, less pictures can be replaced with CSS styles, less thumbnails can be used for lists, and less large images can be used as background for color replacement. If we grasp these points well, we can greatly improve the effective implementation of pictures in SEO.
