1. There were too many navigation links distributed throughout the blog, and I originally intended to remove the sidebar links. However, since the sidebar provides a count of articles for each category, I decided instead to eliminate the header navigation.
2. The biggest improvement was moving the search box to the top. Personally, I believe that in SEO learning and work, Seoers should understand searching better and make full use of it to solve problems because it is more targeted.
3. I added a "Blog Post List" for users who are "too lazy to search." They can browse the page to find articles of interest. The "Blog Post List" is a simple static page, so there is no issue with slow webpage loading speeds.
