Depsite upgrading to the Professional plan, my site continues to hit max capacity

Some friendly advice, YMMV!

I would strongly recommend splitting your approach - rebuild your site with something more purpose built for content / affiliate. You wont get very far in the SEO game when competitors are just gonna load faster by a wide margin (see lighthouse below):


For your interactive piece, move that to a subdomain and use bubble. Then you get best of both worlds (I did this recently with my own site)
