The migration is done, the DNS has switched, and you're live on Shopify. Now what? The first 30 days after migration are critical — this is when issues surface, SEO rankings adjust, and your team adapts to the new platform. This guide covers what to monitor, what to fix, and what to optimize week by week.

Day 1: Launch day monitoring

On launch day itself, keep the following open in separate browser tabs:

Shopify Admin → Orders (refresh every 15 minutes)
Shopify Analytics → Sessions (verify traffic is flowing)
Google Analytics Real-Time → verify pageviews are tracking
Your email inbox (for customer support issues)

Launch day quick checks:

First real customer order: confirm it appears in Shopify Admin and triggers the order confirmation email
At least one redirect: visit an old WooCommerce URL and confirm it redirects to Shopify
Mobile: browse your store on your phone — categories, product pages, checkout
Tracking pixels: open browser developer tools → Network tab → add a product to cart and verify Facebook/GA4 events fire

Days 2–3: Systematic verification

Submit sitemap to Google Search Console

Google Search Console → Sitemaps → Add sitemap
Enter: https://yourdomain.com/sitemap.xml
Shopify automatically generates the sitemap

Check Google Search Console for crawl errors

Coverage report: look for new 404 errors (these are old URLs without redirects)
For each 404: create a redirect in Shopify Admin → Online Store → URL Redirects

Verify Google Analytics is tracking correctly

GA4 → Reports → Real-time: should show active users during your test session
GA4 → Events: verify "purchase", "add_to_cart", "view_item" events are firing
Compare yesterday's data to previous Tuesday's data from WooCommerce (WooCommerce GA data may be in same GA4 property if you kept the same ID)

Review first orders

Check every order from days 1–2 in Shopify Admin
Verify order confirmation emails were sent (check if customer received it)
Confirm payment captured correctly in your payment gateway dashboard
Verify shipping rates are calculating correctly

Days 4–7: Fix issues found in first days

Common first-week issues and fixes

Missing redirects (404s in Search Console)
Fix: add individual redirects in Online Store → Navigation → URL Redirects

Wrong shipping rates
Fix: Admin → Settings → Shipping → review zone configurations and rate conditions

Tax calculating incorrectly
Fix: Admin → Settings → Taxes → verify nexus settings and tax-inclusive vs exclusive configuration

Notification emails look different than expected
Fix: Admin → Settings → Notifications → edit template HTML, send test

Some products missing from collections
Fix: for automated collections, verify product tags are set correctly. For manual collections, add missing products.

Cart not showing correct item images
Fix: verify product images are fully synced to Shopify (check a few products in Admin → Products)

Week 2: Analytics and performance baseline

Establish baseline metrics

By end of week 2, you should have enough data to compare against WooCommerce:

Conversion rate: GA4 → ecommerce → compare to WooCommerce baseline from same period last year
Average order value: Shopify Analytics → Overview
Traffic sources: GA4 → Acquisition → verify organic, direct, email traffic proportions
Page load speed: Google PageSpeed Insights → test your homepage, a product page, and a collection page
Bounce rate / engagement rate: GA4 comparison (note: GA4's engagement rate ≠ WooCommerce's bounce rate — different definition)

Speed comparison

Most WooCommerce → Shopify migrations improve Core Web Vitals significantly:

Run PageSpeed Insights on 3–5 key pages
Compare against saved WooCommerce scores from before migration
If score is worse than expected: check if all Shopify app scripts are loaded correctly (some apps add JS weight)

Week 2–3: SEO monitoring

What to expect from rankings

Rankings typically follow this pattern after migration:

Days 1–7: Little change (Google hasn't recrawled extensively yet)
Days 7–21: Some fluctuation as Google processes the redirect signals
Days 21–42: Rankings begin to stabilize, most pages recover to near pre-migration levels
Days 42–90: Full recovery for properly redirected pages; any permanent losses indicate missing redirects

Monitoring tools

Google Search Console: Performance report → compare clicks/impressions week over week
Google Analytics Organic Traffic: Organic sessions week over week
Rank tracking tool (SEMrush, Ahrefs, Moz): monitor your top 20 keywords weekly

Red flags that need immediate action

Organic traffic drop >40% by day 14 (expected: 10–20% temporary dip)
Large number of 404 errors in Search Console (missing redirects)
Key product pages not appearing in Google's index after 3 weeks

Week 3: Conversion rate optimization

With baseline data available, start optimizing:

Checkout funnel analysis

GA4 → Funnel exploration: create a funnel from product page → add to cart → checkout → purchase
Identify drop-off points vs WooCommerce baseline
Common issues: cart abandonment rate higher than WooCommerce? Check if payment options (Shop Pay, PayPal) are visible

Product page improvements

Verify all products have complete descriptions (check for any truncated HTML from migration)
Check product images: all variants have images? Images loading fast?
Are reviews showing? (If using Judge.me or Okendo, verify reviews are loading)

Mobile experience

50–70% of ecommerce traffic is mobile — test complete checkout on iOS and Android
Verify product images look correct on small screens
Check that buy button is above the fold on mobile product pages

Week 4: Cleanup and future planning

WooCommerce decommission decision

After 30 days stable on Shopify, assess WooCommerce:

Are all remaining tasks that need WooCommerce done? (Order history lookup, any missed data migration)
If yes: keep WooCommerce on read-only for 6 months, then plan decommission
If no: continue using WooCommerce in parallel for specific tasks

Shopify optimization tasks

Set up automated collections properly (review if tag-based collections are working)
Install and configure review app (if not done before launch)
Set up loyalty program (if not done)
Configure upsell/cross-sell apps
Review app performance: are all installed apps working as expected?

30-day success metrics

At the end of 30 days, your migration is successful if:

Revenue is within 20% of pre-migration baseline (temporary dip is normal)
Organic traffic has stabilized or started recovering
No critical 404 errors in Google Search Console from missing redirects
Customer support tickets related to migration are near zero
All payment methods are working correctly (zero failed payment processing issues)
Email marketing automations are firing correctly (abandoned cart, order confirmation)
Google Analytics is tracking accurately (verified against Shopify Analytics)

30-day post-migration checklist summary

Day 1:    Monitor orders, verify redirects, tracking pixels live
Day 2:    Submit sitemap to Search Console, review first orders
Day 3:    Fix any 404s found in Search Console
Days 4-7: Fix issues found in first week
Week 2:   Establish analytics baseline, page speed check
Weeks 2-3: Track SEO rankings, fix missing redirects
Week 3:   Checkout funnel analysis, mobile test
Week 4:   WooCommerce status decision, Shopify optimization
Day 30:   Review success metrics vs pre-migration baseline

The first 30 days are about discovery and stabilization. Most problems surface in the first 7 days and are straightforward to fix. By day 30, you should have a clear picture of how Shopify is performing for your specific store — and the confidence that the migration was the right decision.
