Shopify store slow on mobile and campaign traffic
Shopify speed issues directly reduce conversion. Performance work should focus on product, collection, and checkout-adjacent pages first.
If your site is broken right now or your last developer failed to stabilize it, start with audit triage first.
Common problem signals
- -Mobile product pages load slowly and users exit early.
- -Campaign landing pages lag under traffic spikes.
- -Store feels heavy after adding apps and tracking scripts.
Typical root causes
- -Script-heavy app stack and blocking assets.
- -Inefficient Liquid logic and template duplication.
- -Image strategy not aligned with real viewport usage.
How I fix this
- -Prioritize high-traffic revenue pages.
- -Reduce script and theme bottlenecks.
- -Validate gains in both speed and conversion behavior.
