Shopify’s app store has thousands of options — and installing too many is a fast route to a slow store. The trick is choosing a few that earn their keep. Here are nine categories worth your attention.

  1. Email & SMS (Klaviyo) — the highest-ROI channel in ecommerce. See our email marketing service.
  2. Reviews & UGC — social proof that lifts product-page conversion.
  3. Search & filtering — better on-site search helps customers find and buy faster.
  4. Subscriptions — turn one-off purchases into recurring revenue where it fits.
  5. Loyalty & referrals — reward repeat buyers and turn them into advocates.
  6. Upsell & cross-sell — raise average order value at the cart and checkout.
  7. Bundles — increase AOV and move stock with curated product bundles.
  8. Back-in-stock alerts — capture demand you’d otherwise lose.
  9. Analytics & tracking — server-side tracking so your data (and ad platforms) stay accurate.

A word of warning

Every app adds weight and potential conflicts. Audit regularly, remove what you don’t use, and favour native Shopify features where they’ll do the job. Performance is a feature — protect your Core Web Vitals.
