What does the listing checker look at?
Everything Apple's public data says about a listing: the app name and its length, the description, how many iPhone and iPad screenshots there are, ratings in that country's App Store, the date of the last update, whether What's New has text, languages, price, category, age rating and size.
It puts the things worth a look first, each with the reason from Apple's product page guidance. There's no score. A score would pretend to know what Apple's ranking does, and nobody outside Apple does.
Why can't it see my subtitle and keywords?
Apple doesn't publish them. The subtitle, the keyword field, promotional text and app previews aren't in Apple's public lookup data, so no outside tool can read them reliably. Check them with the character counter instead.
How many screenshots should an app have?
Apple allows up to 10. The first one to three appear in search results when there's no app preview, so those few do most of the work: make them show the app doing its main job. The screenshot size checker tells you whether each file is a size Apple accepts.
How do I get my first ratings?
Ask at the right moment. Apple lets an app show its rating prompt up to three times in 365 days, so use it after someone has just finished something that went well, not on first launch.
The checker shows ratings for the country in your link. A US link shows US ratings.
Why does What's New matter?
Apple shows What's New on the product page and in the Updates tab, so it's one of the few places an existing user reads about your app again. An empty one is a missed chance. A first version doesn't have one, and the checker knows that.
Does it store anything?
No. Your browser asks Apple's public lookup service directly, and nothing is saved, on our side or anywhere else.
