It’s not a requirement but we’d definitely recommend it for any theme, not just ours. This is because Shopify’s code arrangement is sub-optimal in the eyes of Google PageSpeed Insights and page-load times.
The SpeedBoost Ninja App reconfigures the code so your store achieves a higher PageSpeed Insights score and a faster page-load speed.
This way your store will load faster, improving your conversions, particularly on mobile. It will also improve your organic search rankings bringing you more free visitors. Finally, your improved load time will lower your paid ad cost-per-click.
