The verdict in three sentences
Securing a rebuild so you don't lose SEO costs an SEO migration plan of 2,200 to 5,500 EUR in Dublin in 2026, with 4 to 8 weeks of monitoring. The core deliverable is an exhaustive 301 redirect plan validated by a before/after comparison crawl. A botched migration can cut organic traffic by 20 to 40 %, a hidden cost often larger than the rebuild budget itself.
The method that protects your rankings
A loss-free SEO migration follows a rigorous process. Every URL on the old site must be mapped, 301-redirected to its equivalent, and the new site must preserve title tags, metas, Hn and structured data. Post-launch monitoring detects any anomaly before it costs rankings.
| Step | Deliverable | Indicative 2026 cost |
|---|---|---|
| Crawl of the current site | Full URL map | 450 - 900 EUR |
| 301 redirect plan | 1:1 mapping file | 700 - 1,600 EUR |
| On-page preservation | Titles, metas, Hn, schema | 550 - 1,300 EUR |
| Pre-launch QA | Before/after comparison crawl | 350 - 800 EUR |
| Post-migration monitoring | Ranking tracking 4-8 weeks | 550 - 1,300 EUR |
| Total migration plan | 2,200 - 5,500 EUR |
The risks to quantify if you neglect migration
A rebuild without an SEO plan is not free: it exposes you to very real revenue losses. Here are the most common mistakes and their estimated impact.
| Mistake | SEO consequence | Estimated traffic loss | Cost to the business |
|---|---|---|---|
| Missing 301 redirects | Mass 404 errors | -20 to -40 % | High |
| Titles/metas not carried over | Loss of relevance | -10 to -20 % | Medium |
| URLs changed without redirects | Loss of page authority | -15 to -30 % | High |
| robots.txt block left in place | Full deindexing | -80 to -100 % | Critical |
| Structured data lost | Loss of rich snippets | -5 to -15 % | Medium |
For a site generating 50,000 EUR/month via organic, a 30 % loss means 15,000 EUR/month: the 2,200-5,500 EUR migration plan is a profitable insurance.
Mini case study
Elodie, marketing director at a Dublin travel operator, is planning a rebuild on a site that drives 62 % of revenue via organic, about 48,000 EUR/month. The migration plan quote is 4,000 EUR. Without a plan, a conservative 25 % loss would cost 12,000 EUR/month over 3 to 4 months of recovery, i.e. over 40,000 EUR. The migration plan is therefore less than 10 % of the risk avoided.
FAQ

Why does a rebuild lose traffic?
Because URLs often change without redirects, tags get dropped and Google takes time to re-map the site. A migration plan anticipates and fixes these breaks before they hit rankings.
How much does an SEO migration plan cost in Dublin in 2026?
Between 2,200 and 5,500 EUR depending on site size: the price covers the crawl, the 301 redirect plan, on-page preservation and post-launch monitoring.
How long should I monitor after go-live?
Expect 4 to 8 weeks of active monitoring. That is the window during which Google re-crawls the site and where anomalies (404s, redirect chains) must be fixed fast.
Can you really guarantee zero ranking loss?
No absolute guarantee exists, but a rigorous plan brings the risk close to zero. Losses almost always come from avoidable errors, not from the rebuild itself.
Should I migrate all at once or in stages?
For a brochure site, a single well-prepared switch is preferable. For a large site, a batched migration reduces risk and eases monitoring.
