Key takeaways
- Replo migrations are typically heavier on landing pages than other Shopify page-builder migrations because Replo’s audience leans paid-traffic LP teams.
- The sequence is the same as other migrations: inventory, share each URL with Fudge, rebuild on a dev theme, test, publish to live (same URL), uninstall. No new slugs, no redirects.
- Track conversion rate on each migrated LP closely - paid-traffic LPs are usually the highest-stakes pages in the catalogue.
- Don’t migrate active high-spend campaigns first. Start with a medium-priority LP to validate the cycle.
This guide covers moving from Replo to Fudge AI on Shopify. Replo positioned around landing pages for paid traffic; that’s the pattern we see in most migrations from it.
Replo is a capable tool. Teams migrate for structural reasons - native theme code, no app runtime, pages that survive uninstall. See Replo vs Fudge for the broader comparison.
Why you can trust us
Four years inside Shopify, dozens of LP migrations across Replo and other tools. We build Fudge.
The sequence
Same as any page-builder migration, with a few Replo-specific notes.
Step 1: Inventory every live Replo page
In particular, identify:
- Pages with active ad spend (most important to migrate cleanly)
- Pages with high organic traffic (next priority)
- Test variants you can deprecate (Replo experiments that didn’t win - just retire them)
- Pages that haven’t been touched in 6+ months (consider archiving instead of migrating)
Record URL, monthly traffic, ad-platform usage, and last edit. Save the inventory in a shared sheet.
Step 2: Build a non-critical page first
Don’t start with your top-ROAS LP. Pick a medium-traffic, low-stakes Replo page and run the full cycle: share the URL with Fudge, test on dev theme, publish to live, monitor.
This gives you the muscle memory for the high-stakes migrations later.
Step 3: Rebuild in Fudge
Paste the live Replo page URL into Fudge. It reads the existing page and regenerates it as native Liquid + CSS + HTML on an unpublished dev theme at the same URL. Iterate with prompts.
A Replo-specific gotcha: Replo pages built by LP teams often lean on precise pixel positioning (DTC LP aesthetic). When rebuilding, take the chance to switch to flow-based, mobile-first layout. The result usually feels lighter and converts at least as well.
Step 4: Test
Lighthouse Mobile. Add-to-cart through to checkout. Pixel events (Meta, GA4, TikTok, X). Slow-4G simulation.
For paid-traffic LPs especially, confirm UTM handling and ad-platform tracking continue to fire correctly on the dev theme preview. Because the live URL doesn’t change after publish, no ad creative needs to be updated.
Step 5: Publish to live, watch
Publish the dev theme. The URL is unchanged — your theme code now serves the slug instead of the Replo runtime. No 301 redirects, no ad-creative updates, no new analytics entries.
Watch ROAS and conversion rate in the ad platform for 24-48 hours. If anything looks off, investigate before rolling out further migrations.
Step 6: Repeat for the backlog
In priority order. Don’t try to migrate everything in one sprint.
Step 7: Uninstall Replo
After every page is migrated, 14+ days of live analytics confirm no regression, and the theme is clean of Replo script/CSS imports.
A note on test variants
Replo is often used for A/B-tested LP variants. If you have many variants on the same page:
- Identify the winner; rebuild that one
- Retire the losers (don’t migrate)
- If you’ll continue A/B testing post-migration, plan the Fudge build to be variant-friendly (Fudge supports building multiple page variants from prompts)
For Shopify A/B testing tooling see our A/B testing guide.
Why this migration is worth doing for an LP-heavy store
Two compounding wins:
- Page speed. LP-heavy stores often see meaningful mobile LCP improvement after removing the Replo runtime — see our Shopify page builder speed test for the measurement methodology. On paid traffic, even small LCP gains compound on CR.
- Output ownership. Your LPs are now part of your theme, version-controllable, editable by developers, durable across app changes.
For the broader category and other migrations: PageFly to Fudge, GemPages to Fudge, Instant to Fudge, AI vs drag-and-drop.
FAQ
Will my ad ROAS drop during the Replo to Fudge migration?
It shouldn’t, if the new page is built well. The URL is unchanged through the migration, so existing ad creative keeps working. We typically see CR hold or improve after migration because page speed improves. Test on lower-spend campaigns first to confirm before migrating top-ROAS LPs.
Is the Fudge LP workflow as fast as Replo for paid-traffic teams?
Different rhythm. Replo is hands-on visual editing optimised for LP teams. Fudge is prompt-driven and generates a full draft in seconds. After the initial prompt, refinement is also prompt-driven. Most LP teams settle into Fudge in 1-2 weeks of daily use.
Can I keep using Replo’s template library?
No - that’s a Replo-exclusive asset. Fudge has its own template library plus the option to describe a page from scratch. For LPs you’re not happy with structurally on Replo, the migration is a chance to rebuild better.
What about pixel and conversion tracking?
Site-wide pixels (Meta, GA4) usually fire from your theme.liquid and continue working. Replo-specific tracking integrations may need re-implementing in your theme.
Do my Replo pages disappear instantly when I uninstall?
Un-migrated Replo pages typically revert to a Shopify default page or 404 on uninstall. Migrated pages are unaffected — they’re already theme code at the same URL. Migrate or archive every live Replo page before uninstalling.
