One of the issues I am facing currently, we have a website with over 10,000 pages and since we built it with CSR (Client Side Rendering) and CSG (Client Side Generation) it is relatively very expensive with the CDN cost. Purely did this because of the SEO and caching issue.

Do you have a solution for this or is this still how everyone doing this bearing the cost of scale as we are?
I find this an expensive deployment for us. I appreciate your thoughts.
