AI helps medium-large website to improve their SEO performance?

I have a website with over 400 articles, and some of them cover similar topics or contain highly relevant content. While our SEO performance is already quite good, we want to improve it further. However, we lack the human resources to manually review each article for relevance and add internal links where appropriate. I’m wondering if there are any AI tools that could help websites like ours manage this process. Originally, I was considering building my own tool to address this issue. My idea is to leverage a large language model combined with a RAG (Retrieval-Augmented Generation) system, possibly using something like Supabase, to manage and optimize a large website. Does anyone know how to build tools like this?
