I've built my discount code website using Flutter and integrated SEO to get it indexed on Google Search. Regarding SEO, it's working but not performing as well as I'd like. As for page loading speed, it's genuinely problematic when the website has many features. I've tried everything to reduce the page load time from 8 seconds down to 3 seconds, but even 3 seconds is still too long. You can check out my website hosted on Firebase Hosting: https://wong-ancestor.web.app/ It's the same site; I've purchased a domain from GoDaddy and optimized it for Google SEO at https://wongcoupon.com/ (It might change in the future if I decide to switch to a different programming language). You can test the above websites using SEO tools and measure their effectiveness. I'm considering transitioning to a different technology stack to enhance both SEO performance and loading speed. While Flutter is powerful for mobile applications, it may not be the most optimal choice for web projects that require fast load times and effective SEO. Exploring frameworks like React or Next.js, which offer server-side rendering and better SEO capabilities, could be beneficial. Additionally, implementing strategies like code splitting, asset optimization, and leveraging CDNs might further reduce load times. I'm eager to improve the user experience and make the site more accessible to everyone.
