PHP & Laravel Coin WebSite SEO Optimization

I have a live coin-market style website built on PHP 8 and Laravel. Right now the pages load quickly and the data feed is solid, but very little of that matters if Google can’t find the site. I want the codebase tightened up from an on-page SEO perspective so rankings start to climb...
