A 35 percent loss that lasts six months is usually recoverable in part, but it does point to a structural problem, not normal post-migration noise. Well-run migrations are reported to stabilise within weeks. So the job is a diagnostic audit in a fixed order: redirects, indexation, content parity, internal links and speed. Fixing the first one found often moves traffic more than everything after it combined.
Below is the audit order, what each finding means, realistic recovery and what cannot be undone. Our Shopify migration service and Shopify SEO tips give the preventive side.
The diagnostic order
Work down the list. Stop and fix when you find a big one.
| Step | Check | Typical finding |
| 1. Redirects | Crawl old URLs from logs, analytics and backlink tools. Test status codes and targets. | 404s, 302s, chains, wrong targets |
| 2. Indexation | Search Console coverage, sitemaps, robots, noindex and canonicals | Pages dropped from the index or blocked |
| 3. Content parity | Compare titles, headings, copy and category text before and after | Thinner pages and removed collection copy |
| 4. Internal links | Crawl navigation and in-copy links | Orphaned pages and broken paths |
| 5. Speed and rendering | Core Web Vitals and mobile rendering | Heavy theme or apps |
| 6. Structured data | Product, breadcrumb and review markup | Lost rich results |
What a six-month gap usually indicates
Five patterns, in rough order of frequency.
Pages that earned traffic return 404 or land on irrelevant targets.
A launch-time noindex, robots rule or canonical error was never reverted.
Category copy, filters or long descriptions were dropped in the new templates.
Taxonomy changes after launch reset signals. Guides advise 90 days of URL stability.
A heavy theme or too many apps cost rankings.
Is 35 percent recoverable, and how fast
Honest ranges.
- Well-run migrations are reported to stabilise in weeks and grow within about two months.
- Badly redirected migrations are reported to lose 30 to 50 percent and take six to twelve months to recover.
- Fixing redirects often shows signs of recovery within weeks of Google recrawling.
- Content and structure fixes usually take longer to show.
- Expect partial recovery first, with gains continuing as pages are re-evaluated.
These ranges come from agency guides and examples, not guarantees. We do not publish a named recovery chart.
The audit that finds it
A one-week method.
- Export pre-migration top pages by organic clicks and revenue from analytics and Search Console.
- Join them to current status codes, indexation state and content length.
- Rank the gap by lost clicks, not by page count.
- Fix the top twenty percent of lost pages first, with redirects or restored content.
- Track recovery by page group weekly.
What cannot be undone
Set expectations early.
Rule of thumb: the longer a fix waits, the less of the original value it recovers.
Recovery audits, and what we cannot show
We audit post-migration SEO and fix redirects and content. We do not have a published recovery case with a traffic chart and the specific fix, so we do not cite one.

Frequently Asked Questions
Often partly. Third-party guides say well-run migrations recover in weeks to a couple of months, so a six-month gap usually points to a structural problem. Fixing it can restore much of the loss, but lost equity is not guaranteed to return.
Redirects, indexation, content parity, internal links and speed, in that order.
Typically a missing or wrong redirect map, pages blocked or noindexed, content or templates thinner than before, URL or taxonomy changes after launch, or a speed regression.
Rankings and links lost to long-running 404s can decay, deleted content may need rewriting, and time out of the index is gone. Redirects added late can still recover part of the value.
It varies with crawl rate and the size of the fix. Redirect fixes show signs within weeks, while content and structure fixes can take months. See how to protect SEO in a migration.
