Hi @Kavia11
Sorry for the delayed response.
While every theme can have different optimization opportunities, I recommend throwing your store URL into the Shopify Analyzer to identify any actions you can take.
Based on your results from the Shopify Analyzer, I’d recommend checking out our in-depth optimization guide: How to Optimize a Shopify Site: Complete Guide to Faster Load Speed. It can help walk you through some common website optimizations.
Hope this helps! If you have any questions or want to send me your store URL, I can do a more detailed analysis.
Thanks!
