NextJs and SEO

I want to start my first affiliate website around cam affiliates.

I was thinking of using NextJs to create the website because I like the freedom, and I'm more familiar with it than WordPress.

Are there any contraindications to using NextJs for this kind of stuff?
Is vercel a good option for hosting for SEO?

Do I need to add posts to the website to make it rank up? If so, should I use a cms with next?

Interesting I would like to know this too

PWA are very tricky when it comes down to SEO.
The key here is to make indexable every single part of the web that has unique queriable content

And to make it indexable you need:
a) A reachable URL
b) Unique content easily crawlable and readable in the DOM (not a JSON or anything like that)

My recommendation: Don't go with NextJS for your first project, it still has some downsides and some improvements regarding performance are still in beta. I recently helped built a few medium/big websites in NextJS, it was a pain and still is.

Take a look at AstroJS, has quite a lot more SEO ready packages. AstroJS is still pretty fresh, so do keep that in mind. The performance and language are great, very small learning curve when you know NextJS.

Also if you do go with NextJS, Vercel is better than Netlify (until their edge routing is fully ready). As for the CMS, take a look at Strapi.

HI, did you start project? Can I join? I am pretty good at Nextjs

Next.js is great for building dynamic, fast websites, which is good for SEO. Just be ready for more hands-on SEO work compared to WordPress. Vercel is solid for hosting - fast and reliable. And yes, adding quality content is key for ranking. Consider integrating a headless CMS with Next.js for easier content management.

If it's possible with WordPress then go with WP.
WP is best for SEO.
NextJS also has SEO facilities. Just research with it.
