A LASEO technical SEO audit service combines a Screaming Frog and Sitebulb crawl, a JavaScript render check, log file analysis when available, Core Web Vitals data from PageSpeed plus real CrUX field data, schema validation and a full GSC plus GA4 review. Every issue is mapped to the specific template, route or component that causes it, with reproduction steps your engineers can actually use.

Five phases over three to four weeks
A fixed-scope audit that always ships the same six artefacts, no matter how complex the site. You see the timeline on day one and we hit it.
- 01
Discovery call to align on commercial priorities (day 1)
Sixty minutes with your commercial owner to understand which revenue lines, geographies and product categories matter most. The audit is technically thorough across the whole site, but priorities are weighted to the URLs and templates that drive your money. Without this call most audits over-index on long-tail problems that do not move revenue.
- 02
Crawl plus render audit (days 2-8)
Screaming Frog crawl with JavaScript rendering enabled, a Sitebulb crawl for the structural hint reports, plus a separate render audit that compares the raw HTML against the rendered DOM. We log every internal link, every canonical, every hreflang annotation, every meta directive and every status code. Outputs land in the audit shared drive as we go.
- 03
Log file plus GSC plus GA4 baseline (days 8-14)
If you can hand over 30 days of server logs we run a crawl-budget waste analysis. We then pull twelve months of GSC data (clicks, impressions, average position by query and landing page), GA4 data (organic sessions, revenue and conversion rate per landing page) and stitch them together to identify which audit issues sit on URLs that already earn or could earn.
- 04
Schema plus Core Web Vitals deep dive (days 14-20)
Schema validation across every template using the Schema.org Validator and the Rich Results Test. Core Web Vitals analysis combines Lighthouse CI synthetic runs with real CrUX field data for LCP, INP and CLS, broken down per template, per device and per country. We produce a separate CWV remediation plan as part of the audit.
- 05
Prioritised report plus 90-day implementation plan (days 20-28)
Final deliverables: a 30-50 page audit PDF, a 90-minute Loom walkthrough, the prioritised fix queue in your Notion or Linear, the schema validation report, GSC alert setup, and a 90-day implementation plan ranked by impact-to-effort. We either hand it to your team or stay on to execute, your call.
A fix queue,not a recommendations doc.
Every audit ends with the same artefact: a prioritised fix queue inside your Notion or Linear, with each ticket linked back to the audit finding, the page or template affected, and the expected impact on rankings or revenue. Your engineering team has everything they need to start shipping in the same week the audit is delivered.
What an SEO audit actually covers
What goes into a serious technical SEO audit
When buyers compare audits they often look at page count, which is the worst possible metric. A 100-page audit can be padded with screenshots. A 35-page audit can contain every fix that moves the needle. What matters is the depth of each layer, the tooling that backs it up, and how shippable the output is.
Crawl audit and render audit are not the same thing
A Screaming Frog crawl tells you what URLs exist, what status they return and how they link together. A render audit tells you what Googlebot actually sees after JavaScript hydrates. On modern React, Vue and headless setups the two views disagree often. Skipping the render step is the single most common reason audits miss real indexation problems.
Log file analysis is where crawl budget gets diagnosed
Every other audit tool guesses how Googlebot crawls. Log files show exactly what it crawls, how often, with what user agent, against what status code. For sites over 25,000 URLs a log file audit consistently surfaces a top-five revenue-relevant issue that no crawler would catch.
Schema validation goes beyond a passing badge
The Rich Results Test will say 'valid' for schema that is technically correct but missing recommended properties. A serious audit validates every type against schema.org, checks for missing recommended fields, checks for entity nesting issues and verifies the schema matches what is actually on the page.
Core Web Vitals needs both lab and field data
Lighthouse gives you a controlled lab score on one device. CrUX field data shows you what real users on real connections actually experience. Both matter, and the gap between them is often where the actual problem hides.
Backlink and content audits belong in technical audits too
A backlink profile audit (Ahrefs plus GSC links report) reveals toxic links, orphaned authority and lost link equity from migrations. A content gap analysis surfaces topics competitors rank for that you do not. Both belong inside the technical audit because they often explain technical findings.
GSC plus GA4 audit anchors everything in revenue
A pure technical audit ranks findings by technical severity. A LASEO audit cross-references every finding with GSC impressions and GA4 revenue per landing page, so the order of the fix queue is anchored in money rather than tooling severity scores.

How a LASEO audit compares
Audits compared honestly
Free audit tools, generalist agency audits and in-house audits all have legitimate use cases. Here is where a LASEO audit fits and where it does not.
Generic findings, low shippability
- Free or freemium tool spits out a crawl issues export with no human review. No render audit, no log file analysis, no real CrUX data.
- Junior consultant or in some cases an automated tool with a templated narrative wrapped around the export. Seniors only show up on the sales call.
- Spreadsheet of issues with severity scores, or a 100-page PDF heavy on screenshots. Engineering team has to translate each item into work themselves.
- Sorted by technical severity score from the tool. Nobody knows which fixes will move revenue or which will not.
- Audit lands in a Drive folder, the consultant moves on, your team gets back to roadmap work and the audit goes stale within 90 days.
- Quoted as part of a bundled retainer, or priced 'on request' with the real number revealed after a sales process.
Senior judgement, Git-ready fixes
- Screaming Frog plus Sitebulb plus a separate JS render audit, log file analysis when logs are available, PageSpeed plus CrUX field data, GSC plus GA4 cross-reference.
- Senior consultant with 7+ years of technical SEO leads every audit, with a second senior reviewing the report before it ships. No juniors learning on your account.
- Every finding becomes a ticket in your Notion or Linear with template name, reproduction steps, fix description and expected impact. Engineers can pick up and ship without translation.
- Sorted by impact-to-effort, cross-referenced with GSC clicks and GA4 revenue per landing page, anchored in your commercial priorities from the discovery call.
- We hand the fix queue to your team with a 90-day implementation plan, or we stay on to execute, or both. Either way the audit ships into production, not into a folder.
- EUR 4,500 for sites under 5,000 URLs, EUR 8,500 for sites up to 250,000 URLs or international setups. Fixed scope, told on call one.

What audit clients say
Audit findings in their own words
The LASEO audit found a canonical tag conflict on our product templates that had been suppressing indexation for 14 months. Two weeks after fixing it our category pages added 38 percent organic revenue. The audit paid for itself in the first month.
We had three audits before LASEO and they all said roughly the same generic things. LASEO ran log file analysis and found Googlebot wasting 71 percent of its crawl budget on faceted URLs that should have been blocked. Nobody else had even looked at the logs.
What I valued most was the fix queue in our Linear. Every previous audit landed as a PDF and died. The LASEO ticket structure let us start sprint planning the same week. We shipped 47 of 62 tickets in 90 days.

Honest answers about a technical SEO audit service 
What buyers actually ask before commissioning a senior SEO audit.
A LASEO technical SEO audit service runs three to four weeks end to end. Week one covers the discovery call and the initial Screaming Frog and Sitebulb crawl plus the render audit. Week two covers log file analysis, GSC and GA4 baselines, and the start of schema and Core Web Vitals work. Week three finalises the deep-dive findings and starts assembling the report. Week four delivers the 30-50 page PDF, the 90-minute Loom walkthrough, the prioritised fix queue in your Notion or Linear, and the 90-day implementation plan. Faster turnarounds are possible for smaller sites but compress the analysis depth, which is rarely worth it.
