Here are some tips to optimize Magento's layered navigation URLs for SEO:

1. Use clean and descriptive URLs: Use keywords that are relevant to the product category and make sure the URL is easy to read and understand.
2. Use rel=canonical: Add rel=canonical tags to prevent duplicate content issues and improve crawling efficiency.
3. Include only necessary filters: Include only those filters that are relevant to the user's search and avoid adding too many filters that confuse the user.
4. Enable URL rewrites: Enable URL rewrites to make the URLs more user-friendly and search engine friendly.
5. Use robots.txt: Specify which pages you want to be indexed by search engines and which ones you want to exclude using the robots.txt file.
6. Use meta tags: Use title tags and meta descriptions to optimize search engine visibility for each category or subcategory.
7. Avoid dynamic URLs: Avoid using dynamic URLs that contain special characters and instead use static URLs that are easy to read and remember.
8. Optimize for mobile: Make sure your URLs are optimized for mobile devices so that users can easily navigate and find what they're looking for.
