Spelling it out: How to rank higher
Did you know there are apps out there to help you deliver error-free texts? One of them is called Grammarly. The app suggests improvements, and it's up to you to accept or trash those suggestions.
Grammarly corrects spelling errors, grammar problems, hard-to-read sentences and even suggests improvements to the general "tone" or "engagement." But it doesn't do this automatically. You have to accept each change.

It'd be tremendous with an app that can fix all errors by itself, but that is not the case just yet. It's not as easy as you might think, and you can't just accept all suggestions as even apps like Grammarly get it wrong now and then.
Grammarly can be installed as an app you copy your text into, or as a browser extension, or even a keyboard extension on iPad/iPhone. With the extension, checking texts is supposed to be quick and easy, without copying text back-and-forth between the apps. But in reality, that iOS keyboard extension does not work well, so you'll need to copy the text back and forth every time you check it. The Chrome extension seems to work a little bit better than the keyboard extension.
