The verdict in three sentences
A technical SEO audit only pays off when it is ordered against a specification with measurable requirements: crawl scope, indexing checks, performance thresholds and a prioritised fix list. For a Chicago B2B company with a JavaScript heavy site, the realistic scope is a full crawl of 2,000 to 50,000 URLs, a review of crawl budget and JavaScript rendering, mobile Core Web Vitals and 30 to 80 prioritised fixes. Without that written scope you get an 80 page tool export nobody acts on.
Why the specification changes the outcome
Picture the digital lead of an industrial parts distributor in Chicago's West Loop, with a 15,000 SKU catalog built on a React front end, faceted navigation generating thousands of filter URLs, and buyers searching for part numbers and terms like 'hydraulic fittings supplier Chicago'. The audit must answer three questions: can Google crawl and render the right pages, do they load fast enough on mobile, and which fixes bring the most qualified quote requests for the least engineering time.
Ready to fill specification template
| Section | Measurable requirement | You fill in |
|---|---|---|
| Scope | Full crawl of 2,000 to 50,000 URLs incl. subdomains | Estimated URL count, subdomains |
| Crawl budget | Server log analysis over 30 days, share of Googlebot hits on low value URLs | Log access |
| JavaScript rendering | Compare raw HTML vs rendered DOM on 10 page templates | Templates list |
| Indexing | Crawled vs indexed URLs from Search Console | Read access to Search Console |
| Performance | LCP under 2.5 s, INP under 200 ms, CLS under 0.1 on mobile field data | Priority templates |
| Faceted navigation | Rules for parameters, canonicals, noindex | Filters that drive revenue |
| Structured data | Product, Organization, BreadcrumbList validated | Data sources |
| Deliverable | 30 to 80 fixes with impact, effort, owner and test method | Engineering capacity |
Add one clause: every fix must name the affected URLs or template, the expected change and how to verify it in production.

| Kolonell visibility audit | Technical diagnosis, rankings, competitors, priorities | 100,000 FCFA (about €152), deducted from setup if you start within 30 days | 5 to 10 days |
| Freelance technical audit | Crawl plus template review | $2,500 to $6,000, 2026 estimate | 2 to 3 weeks |
| Agency technical audit with log analysis | Full crawl, logs, rendering, 80 fixes | $6,000 to $20,000, 2026 estimate | 3 to 6 weeks |
| Traffic Engine Presence to Flood | Implementation follow up with weekly report | about €191 to €534 a month over 12 months | Ongoing |
The Traffic Engine setup is 300,000 FCFA (about €457). An audit creates no results on its own; it is worth what the implementation behind it is worth, so name owners for each priority before you sign.
| Priority | Rule | Example for a parts distributor |
|---|---|---|
| P1 | Blocks indexing or revenue | Product pages rendered client side with empty HTML |
| P2 | High impact, medium effort | 40,000 filter URLs wasting crawl budget |
| P3 | Medium impact | Duplicate title tags across 3,000 SKUs |
| P4 | Nice to have | Missing breadcrumb markup |
If the audit touches analytics or form data, keep it within your privacy policy; Illinois and several US states now have consumer privacy rules, so share only what the auditor needs.
Mini case study
Illustrative example: Marcus, digital lead at a Chicago parts distributor with 18,000 URLs, of which only 6,500 are indexed. An average order is $3,500 with a 25% margin.

FAQ
How many URLs should the crawl cover?
All of them, typically 2,000 to 50,000 for a B2B catalog. Sampling 200 pages misses faceted navigation and duplication issues.
Why include JavaScript rendering checks?
If key content only appears after JavaScript runs, indexing can be delayed or incomplete. Comparing raw and rendered HTML on 10 templates takes about a day and often finds the biggest issue.
What performance thresholds should I require?
Google's good thresholds are LCP under 2.5 seconds, INP under 200 ms and CLS under 0.1. Ask for field data on at least 3 templates.
How much does a technical SEO audit cost in Chicago?
From about $2,500 for a freelancer to $20,000 for an agency audit with log analysis (2026 estimate). The Kolonell visibility audit costs 100,000 FCFA, about €152.
What happens after the audit?
Fix P1 items within a month, then track indexing and quote requests weekly. That is what the Traffic Engine plans are built for.
