The verdict in three sentences
A B2B site stuck in the results almost always has technical blockers: unindexed pages, wasted crawl budget, missing structured data, weak internal linking. In 2026 in Amsterdam, a technical SEO audit costs 1,500 to 4,500 EUR and delivers a list of fixes prioritized by impact. Typical result: +20 to 40% more indexed pages and a ranking breakthrough in 6 to 12 weeks.
What a technical SEO audit covers
A technical audit doesn't judge content: it verifies that Google can crawl, understand and index the site. We analyze URL structure, HTTP codes, robots.txt, canonical tags, the sitemap, performance, internal linking and structured data (JSON-LD). Each issue is graded by severity and effort.
| Audit scope | What we check | SEO impact |
|---|---|---|
| Crawl & budget | Orphan pages, loops, waste | High |
| Indexing | Stray noindex, canonicals, sitemap | Critical |
| Performance (CWV) | LCP, INP, CLS, weight | High |
| Internal linking | Depth, anchors, clusters | Medium-high |
| Structured data | JSON-LD, rich results eligibility | Medium |
| Mobile & rendering | JS rendering, viewport, usability | High |
2026 pricing and monitoring in Amsterdam
Price varies with site size and depth (express audit vs deep audit with server logs). The action plan costs and prioritizes fixes; monthly monitoring drives implementation and measures gains in Search Console.
| Service | 2026 range (EUR) | Timeline |
|---|---|---|
| Express audit (< 100 pages) | 1,500 - 2,500 | 1 - 2 weeks |
| Deep audit (+ logs, large site) | 3,000 - 4,500 | 2 - 4 weeks |
| Prioritized action plan | 900 - 2,500 | Included or +1 week |
| Monthly monitoring & steering | 400 - 1,200 /month | Ongoing |
| Technical fixes (dev) | 80 - 140 /hour | Per backlog |
| Quarterly re-audit | 700 - 1,500 | Per quarter |
Mini case study
Sophie, marketing director at a consulting firm in Amsterdam, has a 180-page site with only 96 indexed due to misconfigured canonicals and a stale sitemap. She orders a deep audit at 3,400 EUR then monitoring at 700 EUR/month. After fixes, 158 pages are indexed (+65%), and organic traffic rises from 4,200 to 6,100 visits/month in three months. At a 1.8% contact rate and 3,200 EUR value per qualified lead, the 34 extra converted visits per month more than justify the investment, paid back in under two months.

What's the difference between a technical audit and a full SEO audit?
The technical audit (1,500-4,500 EUR) covers crawl, indexing and performance. The full audit adds content, semantics and backlinks, for 3,000 to 8,000 EUR.
How long until results show?
Indexing gains appear 2 to 6 weeks after fixes; ranking follows over 6 to 12 weeks. Critical blockers (noindex, canonicals) deliver the fastest effects.
Do I need monthly monitoring?
Recommended for the first 3 months (400-1,200 EUR/month) to drive fixes and measure gains. After that, a quarterly re-audit is often enough.
Does the audit include the fixes?
No: the audit and action plan list and prioritize; technical implementation bills at 80-140 EUR/hour or as a fixed package depending on the backlog.
How many pages can I expect to re-index?
On a site with blockers, +20 to 40% more indexed pages after fixes is common, widening the surface for capturing traffic.
