+In memos, the tag is written in the content and displayed by a regex parser. If you have some misrecognized tags, you need a good way to manage your tags accurately, especially where they are written.
+
+## Best practices
+
+Put tags always in the first or last line of content.
+
+```markdown
+#Mark #Website 
+The place for anyone from anywhere to build anything
+Whether you’re scaling your startup or just learning how to code, GitHub is your home. 
+Join the world’s largest developer platform to build the innovations that empower humanity. 
+Let’s build from here.
+```
+
+```markdown
+GitHub Copilot is your AI pair programmer that empowers you to complete tasks 55% faster by turning natural language prompts into coding 
+suggestions.
+#Mark #Utils 
+```
+
+## Not a good practice
+
+DO NOT add tags in the middle of the content. For example, in the GitHub markdown codeblock, the tag syntax will not be recognized.
+
+```markdown
+GitHub Actions automates your build, test, and deployment workflow with simple and secure CI/CD. #Mark 
+```
+
+```markdown
+GitHub Mobile fits your projects in your pocket, #Mark 
+so you never miss a beat while on the go.
