The verdict in three sentences
A technical SEO audit run before a rebuild is the best insurance against losing traffic. In 2026 in Dublin it costs EUR 1 800-5 500, covers 40 to 120 checkpoints and ships in 2 to 3 weeks. It produces a redirect plan, a crawl and indexing map, and an actionable performance roadmap.
The scope of a technical audit in 2026
A serious quote details the areas analysed. Here is the standard scope and what it checks.
| Area | Checkpoints | Deliverable |
|---|---|---|
| Crawl & architecture | Depth, orphans, crawl budget | Map + priorities |
| Indexing | robots.txt, sitemap, canonicals, noindex | Indexing state by type |
| Redirects | 1:1 old/new mapping | 301 redirect plan |
| Internal linking | Silos, anchors, internal PageRank | Linking recommendations |
| Performance | LCP, INP, CLS, page weight | Quick wins + projects |
| Schema & data | JSON-LD, hreflang, markup | Markup fixes |
The number of checkpoints (40 for a small site, 120 for a complex e-commerce) drives the price. A multilingual site with hreflang requires more time.
Price by site size
Budget depends mainly on URL volume and technical complexity. 2026 order of magnitude.
| Site type | URLs | Audit cost (EUR) | Timeline |
|---|---|---|---|
| SME brochure site | < 50 | 1 800 - 2 800 | 1-2 weeks |
| B2B / content site | 50 - 500 | 2 800 - 3 800 | 2 weeks |
| Mid e-commerce | 500 - 5 000 | 3 800 - 5 000 | 2-3 weeks |
| E-commerce / multilingual | > 5 000 | 5 500+ | 3-4 weeks |
| Dublin market average | - | 1 800 - 5 500 | 2-3 weeks |
Mini case study
Aoife, digital lead at a B2B distributor in Dublin, plans a rebuild of her 1 200-URL site generating 45 000 SEO visits/month. She orders a technical audit at EUR 3 200 before the rebuild. The audit reveals 180 high-traffic URLs with no redirect plan foreseen by the rebuild agency. Thanks to the 1:1 mapping delivered, she avoids an estimated 30 % traffic loss over 3 months, i.e. 13 500 visits/month valued at EUR 35/lead on a 2 % conversion rate: roughly EUR 9 450/month preserved. The audit pays for itself at go-live.

Why audit before and not after the rebuild?
Because afterwards the damage is done: broken URLs, missing redirects, ranking drops. Auditing before lets you build the redirect plan and preserve existing SEO value.
Does a technical audit include content?
A purely technical audit focuses on crawl, indexing, redirects and performance. Editorial and semantic analysis is a separate content audit, which can be bundled.
How long does an audit stay valid?
Structural recommendations remain valid 6 to 12 months. Beyond that, or after a major rebuild, a fresh check is recommended to verify indexing and redirects.
Do you provide a ready-to-implement redirect plan?
Yes, we deliver a 1:1 mapping file (old URL to new) directly usable by your developers or CMS, with the 301 rules to apply.
Who should receive the audit: marketing or technical?
Both. We deliver a decision-focused summary for marketing and a detailed technical document for developers, so every fix is prioritised and implementable.
