SEO Optimization Tips for Next.js

**Issue:**
I want to improve the SEO performance of my Next.js application, and I'm looking for tips and best practices. What are the recommended strategies for optimizing metadata, handling canonical URLs, and ensuring proper indexing by search engines?

**Questions:**
1. How can I customize meta tags for individual pages?
2. What are the best practices for handling dynamic routes and SEO?

**Additional Information:**
- Next.js version: X.X.X
- Current SEO configuration: [insert details]

Start by obtaining the missing Next.js version and current SEO configuration, then clarify whether the request is for project-specific changes or general guidance on metadata, canonical URLs, indexing, and dynamic routes. No files, entry points, or tests are identified, so completion cannot yet be verified.
