This post covers: how we picked these apps, shogun (landing page builder), judge.me (reviews and ugc), klaviyo (email and sms recovery), reconvert (post-purchase upsells), hotjar (heatmaps and session recording).
1. How We Picked These Apps
The Shopify app store is full of apps that promise to "boost conversions." Most of them don't deliver measurable results. We picked these 7 based on a specific criteria: we've seen them produce measurable conversion improvements across multiple client stores, not just one.
This list isn't based on affiliate deals or app store ratings. It's based on what we've installed, tested, and measured in the Shopify stores we manage. Some are free. Some are expensive. Price doesn't determine value, results do.
One important caveat: every app you install adds JavaScript to your store and can slow down your page load time. Only install what you'll actually use, and regularly audit your installed apps to remove anything that's no longer pulling its weight.
2. Shogun (Landing Page Builder)
What it does: Drag-and-drop page builder for Shopify. Create custom landing pages, product pages, and collection pages without writing code.
Why it matters for conversion: Building dedicated landing pages for paid ads is one of the highest-impact things you can do for conversion rate. Shogun lets you build these quickly, and their higher plans include built-in A/B testing so you can test variations without another tool.
The numbers: Stores that switched from sending ad traffic to product pages to Shogun-built landing pages saw an average 65% increase in conversion rate across our client base. Some saw 2x or more.
Pricing: Starts at $39/month. A/B testing available on $149/month plan.
3. Judge.me (Reviews and UGC)
What it does: Product review collection and display. Sends automated review request emails, supports photo and video reviews, and adds review widgets to your store.
Why it matters: Social proof is one of the biggest conversion drivers for cold traffic. Products with reviews convert 2-3x higher than products without. And photo reviews are even more effective because they feel authentic.
Why Judge.me specifically: It's significantly cheaper than Yotpo and Stamped (the other major review platforms), has a generous free plan, and the page speed impact is lighter. The free plan is genuinely usable, which is rare.
Pricing: Free plan covers most needs. Paid plan at $15/month adds features like review carousels and Q&A.
4. Klaviyo (Email and SMS Recovery)
What it does: Email and SMS marketing platform built for ecommerce. Automated flows for abandoned carts, post-purchase follow-ups, win-back campaigns, and more.
Why it matters: Abandoned cart email flows recover 5-15% of lost revenue on average. That's revenue from visitors who already showed purchase intent. The ROI on setting up Klaviyo flows is usually very high because the revenue is incremental.
The setup that matters most: Abandoned cart (3-email sequence), browse abandonment, and post-purchase follow-up. These three flows alone handle the highest-value automation opportunities. Everything else is a bonus.
Pricing: Free for up to 500 contacts. Paid plans start around $20/month and scale with list size.
5. ReConvert (Post-Purchase Upsells)
What it does: Adds upsell and cross-sell offers to your order confirmation page and thank-you page. Buyers can add items with one click after purchase, no need to re-enter payment details.
Why it matters: Post-purchase upsells convert at 10-15%, far higher than pre-purchase cross-sells. Because the buyer has already committed, the psychology shifts from "should I buy?" to "should I add one more thing?" That's a much easier conversion.
The impact: Across our clients using ReConvert, average order value increased by 8-12%. The key is offering relevant products, not random items from your catalog. For details on checkout optimization, see our Shopify checkout optimization guide.
Pricing: Free for up to 49 orders/month. Paid plans from $7.99/month.
6. Elevar (Conversion Tracking)
What it does: Server-side conversion tracking for Shopify. Ensures your Meta Pixel, Google Ads, and GA4 tags fire correctly and capture all conversion events.
Why it matters: This isn't a traditional "conversion app." But broken tracking means your ad platforms don't know which clicks convert, so they can't properly adjust bidding. Fixing tracking doesn't change your website conversion rate directly, but it dramatically improves your ad campaign performance by feeding better data to the algorithms.
When you need it: If you've noticed discrepancies between Shopify orders and Google Ads or Meta reported conversions, Elevar is probably the fix. It routes conversion data server-side, bypassing ad blockers and iOS tracking restrictions.
Pricing: Starts at $150/month. Worth it for stores spending $5K+/month on ads.
7. Lucky Orange (Real-Time Analytics)
What it does: Heatmaps, session recordings, form analytics, and live visitor dashboard. Shows you exactly how visitors interact with your pages.
Why it matters: You can't improve what you can't see. Watching 20-30 session recordings of visitors on your landing page reveals friction points that analytics numbers alone can't show. You'll see where visitors get confused, where they hesitate, and where they leave.
Practical use: Before running any A/B test, watch session recordings to form a hypothesis. "Visitors seem to scroll past the CTA without seeing it" is a better starting point than "let's test a different button color."
Pricing: Free plan includes 500 sessions/month. Paid plans from $32/month.
The bottom line: install the apps that address your specific conversion bottleneck. If you don't have reviews, Judge.me. If you're losing carts, Klaviyo. If your ad traffic bounces, Shogun for landing pages. Don't install all 7 at once, because the combined script weight will slow your store and create a new problem.

Frequently Asked Questions
Yes, most apps add JavaScript that increases page load time. The impact varies from negligible to significant. Only install apps you actively use, and regularly audit installed apps. Use Google PageSpeed Insights to measure the before and after impact of each app.
It depends on your biggest bottleneck. For stores running paid ads, a landing page builder like Shogun usually has the biggest impact. For stores with low trust signals, a review app like Judge.me is more important. Identify your weakest point and address that first.
Some are. Judge.me's free plan is genuinely useful. Klaviyo's free plan works for small stores. But most free apps have limitations that matter at scale. If you are spending significant money on ads, the paid versions usually pay for themselves in recovered conversions.
