The verdict in three sentences
A successful WordPress migration in Berlin is judged not at launch but 8 weeks later: if organic traffic returns to its baseline, you have won. The number-one risk is not technical, it is a missing URL in the redirect plan. Realistic 2026 budget: 3,500 to 7,000 EUR, for a controlled traffic loss under 5%.
What actually costs money in an SEO migration
Migration is not just moving files. The line item that protects your rankings is the URL mapping: matching every old address to its new destination, one by one.
| Item | 2026 range (EUR) | What it covers |
|---|---|---|
| Pre-migration SEO audit | 600 - 1,200 | Full crawl, top pages, backlinks |
| URL mapping | 800 - 1,500 | Old-to-new URL matching |
| 301 redirect setup | 500 - 1,100 | Server rules, tests, chains avoided |
| Post-migration QA | 700 - 1,400 | Indexing check, 404 errors |
| 8-week monitoring | 400 - 900 | Search Console, adjustments |
| Total | 3,500 - 7,000 | Fully secured migration |
For a 40-to-80-page corporate site, the mid-range (around 4,800 EUR) is the 2026 norm in Berlin.
The checklist that avoids disaster
These checks happen in order, before and after cutover. Skip a single one and you risk a ranking drop.
| Step | Before/After | Success indicator |
|---|---|---|
| Export full URL list | Before | 100% of indexed URLs listed |
| 301 redirect table | Before | 0 URL without a destination |
| Preserve title/meta tags | Before | Identical or improved |
| Regenerate XML sitemap | After | Submitted to Search Console day 0 |
| 404 error test | After | < 1% of URLs return 404 |
| Internal link check | After | 0 link pointing to old scheme |
| Rankings monitoring | After | Back to normal weeks 4 to 8 |
Typical end-to-end timeline: 3 weeks of prep and cutover, then 4 to 8 weeks of observation.
Mini case study
Take Julian, web manager at an architecture firm in Berlin, with a 62-page site generating 3,200 organic visits per month. Without a migration plan, a redesign would have cost him 30 to 40% of traffic for 3 months, roughly 3,500 lost visits valued at 4 EUR per equivalent click, so 14,000 EUR of value gone. With rigorous mapping at 4,800 EUR, his real loss capped at 4% and everything recovered in 6 weeks. The migration plan paid for itself in the first month.

FAQ
Will I inevitably lose traffic when migrating?
A temporary 3-to-5% dip is normal while Google recrawls the site. Beyond 10%, it signals incomplete mapping or poorly configured redirects.
How long to recover my rankings?
Expect 4 to 8 weeks depending on site size and crawl frequency. A site under 100 pages usually returns in 4 to 5 weeks.
Are 301 redirects enough on their own?
They are essential but not sufficient: you must also preserve title tags, update internal links, and regenerate the sitemap on cutover day.
Can we migrate with zero downtime?
Yes, with a prepared DNS switch and a tested staging environment. Real downtime is limited to a few minutes.
Should we notify Google?
You do not "notify" it, but you submit the new sitemap and watch the coverage report in Search Console from day one.
