5 CRO Questions - Thank you so much for your time in answering!

For reference, I sell higher ticket jewelry / watch products.

1. Highlighting Discounts Effectively

What are the most effective ways to display discount pricing on a Shopify product page to increase conversion? (e.g., strikethrough original price, $ saved, % saved, etc., color choices)?

Any styling techniques or apps you recommend for high-converting presentation?

2. “Buy It Now” vs “Add to Cart” Optimization

Are there any best practices around the visual hierarchy between “Add to Cart” and “Buy Now” buttons? My default theme makes the Add to Cart very dull so it doesn’t compete with the Buy button.

3. Sticky Add to Cart – Scroll vs Action

Long product page due to reviews with images. Due to this I have added an “Add to Cart” button that is persistent on the page. I’m trying it out. Have you seen higher conversion from sticky “Add to Cart” bars that actually add the item to cart vs those that just scroll to the main button (this is how my theme is set up by default). Is it worth customizing this to take the action directly instead of just scrolling?

4. Font & Design Perception

Curious if font choices have a meaningful impact on conversion — have you seen certain font pairings or styles lead to better perceived value / trust on DTC sites? I had this recommendation from a friend to use a more “premium” or “luxurious” font.

What’s the best way to determine if a design or copy change is actually improving conversion?

5. Measuring CRO Impact

I’ve been making minor updates, but it’s tough to know what’s working without formal A/B testing. Any tools, tips, or simplified methods you recommend for someone early on in CRO testing? If I want to do A/B testing what are the best way(s) to do it?

Hey! Great set of questions. Here’s how I’d approach each one, especially for high-ticket items like jewelry or watches:

1. Highlighting Discounts Effectively

Strikethrough pricing tends to work well, and showing either the % or $ saved can help. For higher-ticket items, showing the actual dollar value (like “Save $150”) usually hits harder. Just make sure it still looks clean and on-brand. You don’t want the discount style to cheapen the overall feel.

2. “Buy It Now” vs “Add to Cart” Optimization

If it’s not an impulsive purchase, you might actually be better off removing the “buy now” option. Most people want to double-check details or browse a bit more. In that case, “Add to Cart” should clearly be the main CTA — visually and structurally.

3. Sticky Add to Cart – Scroll vs Action

I’ve seen both setups work. For higher-end products, it often makes more sense for the sticky bar to scroll back to the main selectors instead of auto-adding. That way people can reconfirm their choices before committing. If you do switch to direct-add, just make sure it handles all required selections without issues.

4. Font & Design Perception

Fonts matter a bit for trust and overall look, but I’ve never seen a font swap move the needle on conversion. Choosing a more premium-looking font can help from a brand perspective — just don’t expect it to be the reason someone buys. Readability and consistency usually matter more than the actual font style.

5. Measuring CRO Impact

If you’re just getting started, I’d go with controlled changes. Basically, log what you changed and when, and keep an eye on your metrics after. It’s not perfect, but better than guessing. Once you’ve got a bit more traffic or a steady flow of orders, A/B testing becomes a lot more useful. Tools like Intelligems or Convert can help with that when the time comes.

Hope this gives you a few ideas to run with.
