Detailed Breakdown
Speed Optimization Depth
Avada is an SEO suite that includes speed features. Thunder is a speed optimizer and nothing else. That focus matters.
Thunder scans every installed Shopify app, measures each script's impact on your page load time, and produces per-app speed impact reports. It also provides real-time Core Web Vitals monitoring directly in your dashboard.
Avada's speed features include lazy loading, image optimization, Google Fonts optimization, and preloading. Solid fundamentals, but the same features you'll find in most speed apps. Avada doesn't analyze third-party scripts or tell you which apps are the problem.
SEO Features
This is where Avada dominates — full SEO toolkit: meta tag management, structured data/rich snippets, automatic image ALT tags, broken link detection, 404 redirects, and more. Thunder doesn't do SEO beyond speed.
The All-in-One Trade-Off
Avada is a Swiss Army knife. Thunder is a scalpel. Avada's speed features are good but not best-in-class. Thunder's speed features are its entire product — deeper optimization, more granular reporting, faster iteration on speed improvements.
When to Pair Avada SEO With Thunder
Use both when Avada is handling SEO operations but your store still fails Core Web Vitals. Avada can manage meta titles, schema, image alt text, and SEO audits while Thunder handles the storefront performance layer: app script deferral, critical CSS, and speed monitoring.
This is especially useful for stores with review widgets, popups, analytics tags, subscriptions, bundles, and page builders. Start with the free Shopify speed test, compare dedicated speed tools in the best Shopify speed apps guide, then check Thunder pricing if the bottleneck is speed rather than SEO setup.

Test Your Store Speed Free →Frequently Asked Questions
Is Thunder better than Avada SEO Suite for page speed?
For pure speed optimization, yes. Thunder specializes in page speed with unique features like third-party app script scanning and per-app speed impact reports. Avada includes speed features but as part of a broader SEO suite, so its speed tools are less deep. Thunder has a free plan and paid plans from $19.99/mo with a 7-day free trial.
Can I use Thunder and Avada together?
Yes — this is actually the ideal setup for many stores. Use Avada for SEO features (meta tags, structured data, redirects) and Thunder for speed optimization. Just disable Avada's speed features (lazy loading, image optimization) to prevent conflicts.
Is Avada SEO Suite worth the price compared to Thunder?
They serve different purposes. Avada's paid plans start at $34.95/mo for a full SEO toolkit. Thunder's paid plans start at $19.99/mo (Shopify plan, 7-day free trial) for dedicated speed optimization. If speed is your only concern, Thunder offers much better value. If you need SEO tools too, consider using both — Avada for SEO, Thunder for speed.
Does Avada SEO Suite scan third-party app scripts?
No. Avada's speed features focus on lazy loading, image optimization, and Google Fonts optimization. It doesn't analyze which installed apps are slowing your store down. This is a unique Thunder feature.
Does Avada SEO Suite affect my store's page load time?
Yes — like any app, Avada adds JavaScript to your storefront. Because it's an all-in-one suite (SEO + speed + image optimization), its script footprint is larger than a focused tool. Independent tests show Avada's scripts add 150–300ms to page load on mobile. If you pair Avada with Thunder, Thunder can defer Avada's non-critical scripts to minimize the impact.
Which app should I get first — Thunder or Avada?
If your store is slow, start with Thunder — speed directly impacts conversions and revenue. Thunder's free plan lets you diagnose speed issues immediately. Once your speed is optimized, add Avada for SEO improvements. A fast store with good SEO is the winning combination.
