Deep Tech SEO Audit | Forensic Technical Analysis
Professional technical SEO audit: comprehensive forensic analysis of crawl budget, Core Web Vitals, JavaScript rendering and penalty recovery. Discover the technical brakes on your site.
What is the Deep Tech Audit?
The Deep Tech Audit is an in-depth technical analysis of your website, designed to identify all the issues preventing Google from properly crawling, indexing and ranking your pages.
It’s not just an automated Screaming Frog report. It’s a manual forensic analysis where every data point is interpreted in the context of your business, your niche and your growth objectives.
At the end of the audit you’ll receive a strategic document with clear action priorities, organized by impact/effort, ready to hand to your development team.
Who is it for
Sites in decline
You lost traffic after an algorithm update or migration and don't understand why.
Blocked indexing
You publish content but Google doesn't index it, or indexes it but doesn't rank it.
Slow sites
Core Web Vitals in red, users abandoning, mobile penalties.
E-commerce or SaaS
Complex platforms with thousands of pages, filters, JavaScript rendering.

Specific FAQ
How long does a complete audit take?
From 5 to 7 working days from tool access to report delivery. For very large sites (>10,000 pages) a few extra days may be needed. I’ll communicate a precise timeline after the kickoff call.
Does it include implementation of fixes?
No, the Deep Tech Audit is a diagnostic service. I provide the report with all detailed technical indications, but implementation is handled by your development team. I can support them during implementation with a separate hourly consulting package.
Which tools do you use for analysis?
I combine professional tools (Screaming Frog, Sitebulb, PageSpeed Insights, WebPageTest, Log Analyzer) with manual analysis. I don’t stop at automated data, but interpret every metric in the context of your business.
Is it suitable for e-commerce too?
Absolutely yes. In fact, e-commerce sites benefit most from an in-depth technical audit, given their greater complexity (filters, faceted navigation, duplicate product sheets, stock management). I have specific experience on Shopify, WooCommerce, Magento and custom platforms.
