2024-07-25

Web performance is one of the practical levers that changes what a website is worth at exit. This guide covers how to apply it in a flipping workflow—build, improve, document, and sell—without turning the site into an untransferable personal project.

Common Mistakes to Avoid

These errors show up again and again in failed flips and discounted sales.

What Buyers Want to See

Document these items before you list. Clear evidence shortens diligence and supports a higher ask.

• CrUX or Lighthouse reports
• Before/after conversion notes

Practical Checklist

• Capture a baseline metric related to web performance before changes
• Ship the highest-leverage fix first
• Document the before/after in your data room
• Add or update an SOP so the improvement survives handoff
• Mention the improvement briefly in the listing proof block

Conclusion

Performance is not vanity. It is a ranking, conversion, and diligence signal—optimize it before buyers ding your price.
