SEO (Search Engine Optimization, search engine ranking technology) has never been a very profound subject. Personally, I think SEO is actually made up of many details. Modifying one small part may not have much impact on the website, but when many details are combined, it can bring about significant effects. As an SEOer, the most important thing is to be patient and persistent. I believe that as long as you keep working hard, there will be rewards, and hard work will pay off! We also need to continuously monitor the latest changes in Baidu and Google, and learn from our competitors' methods to improve ourselves by adopting their strengths and compensating for our weaknesses.
