1. Nothing is wrong with SEO. But I expected a blog in a similar fashion as your .dev page but I was highly disappointed when all I saw where these "empty" click-bait esque posts.
2. I've seen plenty of apps doing the same trick in the App Store. But if it doesn't affect the search indexing why even bother putting up a long list of apps that could hurt your business.
Nothing but respect for the work that you do and the app you've created.
