Implement specific schema markup for your SPA's content. This structured data helps search engines understand the context and relationships between different elements on your pages, potentially leading to enhanced rich snippets in search results.
Encourage user-generated content, such as comments and reviews, as it can enhance SEO by adding valuable content and keywords to your SPA. Ensure that user-generated content is monitored for quality and spam.
Understand that Google primarily uses the mobile version of your SPA for indexing and ranking.
