still can't write paragraph writing - what am i missing?

If it feels disconnected, look at how each paragraph starts. The first few words should link back to what you just said - so, but, that's why, the other option is. Without those the paragraphs read like separate notes stuck together, even if each one is fine on its own.

Topic sentence, support, wrap. That's the order. Keep them to 2-4 sentences for web copy since people read on phones and a big block looks like a wall. Does your draft feel too long, or too disconnected?
