What are the key metrics that you look for Web App optimization?

Note: I'll try to include the most relevant metrics on the Part 4 of my Front End Developer Automation series. If you'd like to collaborate, please let me know @papaponmx.

For me the depending on the topic, some of those are:

  • <meta> tags presence and confirm that they include relevant content.
  • Validate all html tags.
  • First meaningful paint.
  • Number, size and latency of initial requests and their relevance.
  • Font sizes and images size on mobile devices.
  • Color contrast ratio.
  • Can I traverse the app just with the keyboard?

What are yours?

Academically it should, in practice most companies will not schedule the time for the work required to make this happen. It's just a cost sink for them.

Having said that, if your app is a mithril or react app written in javascript, what exactly is supposed to happen for someone with javascript disabled?

Just a: "Please enable javascript to use this site" seems good enough for them.

Should it? Under which circumstances someone might disable Javascript?

But that's a totally different thing.
