I've built design assets for a lot of online coaches now, and there's one mistake I see constantly: people treat their sales slide deck like a school presentation instead of a sales page.

A few things that actually move the needle:

1. One idea per slide. If you're cramming 3 bullet points and a paragraph onto a slide, your audience is reading instead of listening. Cut it down until the slide is basically a headline.

2. Consistent visual hierarchy. Pick ONE accent color for emphasis and use it sparingly — for your price, your CTA, your biggest promise. If everything is highlighted, nothing is.

3. Show, don't just tell, your results. A screenshot of a testimonial DM beats a bullet point that says "great results" every time. Visual proof > claims.

4. Design for the replay, not just the live. Most people watching your webinar/pitch will rewatch it later or skim screenshots. Make sure key slides (offer, pricing, guarantee) make sense as standalone images.

5. Brand consistency compounds. The 10th time someone sees your color palette and fonts, they recognize you before they read a word. That recognition is worth more than any single "clever" design choice.

Small design fixes like these are usually the difference between a deck that looks "fine" and one that actually converts. Happy to break down any of these further if useful.
