LASEO is a technical SEO agency that writes the code, deploys the schema, and edits the robots.txt directly in your repo. Our engineers have 7 to 14 years inside Shopify Liquid, Next.js, Sanity, Magento and headless stacks. We do not hand recommendations to your developer and disappear. We open the PR.

How a LASEO technical SEO engagement runs
Six tactical phases. Each one ends in something shipped to your repo or your GSC, not a slide. No proprietary methodology you cannot replicate after we leave.
- 01
Log file analysis (weeks 1-2)
30-90 days of server logs ingested into Screaming Frog Log File Analyser or Splunk. We map Googlebot, Bingbot and AI crawler hits against your URL inventory, isolate orphan-crawled URLs, and quantify crawl budget waste on faceted navigation, search pages and parameterised URLs.
- 02
Crawl + canonical architecture audit (weeks 2-3)
Full Screaming Frog and Sitebulb crawl with custom extraction. We map every canonical, hreflang cluster, redirect chain, and pagination signal. Output: a prioritised fix queue with reproduction steps and the exact file path in your codebase for each issue.
- 03
Schema deployment (weeks 3-5)
JSON-LD library shipped as Liquid snippets, Next.js metadata helpers or Sanity schemas. Product, Article, FAQPage, BreadcrumbList, Service, Organization, Review. Validated with Rich Results Test and Schema Markup Validator. Deployed via PR, monitored in GSC Enhancements.
- 04
Core Web Vitals fix sprint (weeks 4-8)
LCP, INP and CLS measured per template using GSC, CrUX and Lighthouse. Render-blocking JS removed, images preloaded and converted to AVIF/WebP, fonts self-hosted with font-display swap, third-party scripts deferred. Verified with WebPageTest filmstrips on real devices.
- 05
JS rendering + indexability fixes (weeks 6-10)
For SPAs and JS-heavy stacks we audit how Googlebot renders your pages using GSC URL Inspector and Mobile-Friendly Test. We then ship SSR, prerender, or dynamic rendering configs depending on your stack: Hydrogen, Next.js, Nuxt, or Cloudflare Workers at the edge.
- 06
Continuous crawl monitoring (ongoing)
Weekly Sitebulb crawl diffed against last week. Alerts wired into your Slack when new 4xx/5xx clusters appear, canonicals drift, hreflang breaks, or schema disappears from GSC Enhancements. Monthly technical health scorecard delivered with the executive report.
Think of us asyour fractional head of technical SEO.
We sit between your CTO and your marketing team. Log files crawled monthly. Canonicals defended weekly. Schema validated on every deploy. Core Web Vitals tracked per template, not just per origin. The function most agencies pretend to staff but cannot ship to production.
What technical SEO actually means
Technical SEO, explained without the audit-deck cliches
Technical SEO is everything between Googlebot and your content: crawling, rendering, indexing, canonicalisation, internationalisation, structured data and speed. When it is wrong, your best content cannot rank because Google cannot read it. When it is right, you stop fighting your own stack.
Technical SEO vs on-page SEO
On-page SEO is what is on the page: title, headings, copy, internal links, image alts. Technical SEO is everything Googlebot needs to reach and render that page: robots.txt, canonicals, hreflang, sitemaps, schema, rendering, speed. Same site, different layer. You need both.
Audit vs implementation
Audit agencies hand you a list of issues. Implementation agencies (us) write the canonical rule, deploy the schema, fix the render-blocking JS, and verify the result in GSC. Most companies do not need another audit; they need the audit shipped.
Generalist agency vs technical SEO firm
Generalist agencies have one technical SEO splitting time across 20+ accounts and rarely touching code. A technical SEO firm has senior engineers who actually open PRs against client repos, defend architecture decisions to CTOs, and own crawl health as a continuous discipline.
In-house developer vs technical SEO engineer
Your developer knows your stack. A technical SEO engineer knows your stack plus how Googlebot processes JS, when prerender beats SSR, why hreflang clusters break in subdomain setups, and how crawl budget reacts to faceted navigation. Both are needed; the engineer briefs the developer.
What a technical SEO audit actually costs
A serious technical SEO audit in Europe runs EUR 4,000-15,000 for a one-off, depending on URL volume and stack complexity. Anything under EUR 2,000 is almost always a Screaming Frog export with a templated PDF. Continuous technical SEO retainers run EUR 4,000-12,000 monthly for active implementation.
When to run a technical SEO audit
Run one before a replatform, after a migration, when traffic drops without a content reason, when GSC reports a sudden indexing decline, before a Core Update lands, or every 12 months as hygiene. Audits between these moments are usually a waste unless something concrete changed.

Why LASEO vs alternatives
Technical SEO agencies compared honestly
Generalist agencies, freelance technical SEOs, and in-house specialists all have legitimate use cases. Here is where LASEO fits and where it does not.
Audits the issue, hands it over
- 60-page PDF or 40-tab Excel with prioritised issues. You hire a developer separately to ship them, often months later.
- Not included, or included as a one-off Excel export of one week of logs with no follow-up.
- Pasted into a doc as JSON-LD examples. You implement them. They drift out of date with your product data.
- One Lighthouse score per page in a deck. No template-level split. No before/after verification.
- One Screaming Frog crawl per quarter. You learn about indexing drops from a traffic chart a month later.
- Account manager forwards your CTO's pushback to the technical SEO. Three days later you get a hedged email.
Audits, ships the PR, monitors
- Git PRs against your repo. Your engineers review and merge. Robots.txt, canonicals, schema, hreflang and CWV fixes shipped to production.
- 30-90 days of logs on day one, then monthly. Crawl budget tracked per URL bucket. Googlebot, Bingbot and AI bot activity isolated.
- Deployed as code: Liquid snippets, Next.js metadata helpers or Sanity schemas, bound to your real product feed. Validated on every deploy.
- LCP, INP and CLS split per template using GSC and CrUX. Fixes shipped as PRs, verified with WebPageTest filmstrips on real devices.
- Weekly Sitebulb crawl diffed against last week. Slack alerts on new 4xx/5xx clusters, canonical drift, hreflang breaks, schema loss.
- Senior technical SEO engineer sits in the architecture call. Defends the decision in real time, in your CTO's language, with reproduction data.

What our technical SEO clients say
Technical SEO in their own words
We had three audits before LASEO, all PDFs, none shipped. LASEO opened 22 PRs in the first month. Six weeks later GSC indexed 38% more URLs and the category templates passed Good CWV.
Their log file analysis caught Googlebot wasting 41% of crawl budget on faceted URLs we had been arguing about internally for a year. They shipped the robots.txt fix the same week. Index quality came back within a month.
What I value is the weekly crawl diff in Slack. We catch canonical drift before it costs us traffic. Previous agencies would tell us a month later, in a deck. LASEO tells us the same day, in a thread, with the fix already in a branch.

Honest answers about technical SEO 
What technical buyers actually ask before signing a technical SEO retainer.
Ask three questions in the pitch. First, will the technical SEO who runs my account write code in my repo, or only hand off recommendations? If only recommendations, you are buying an audit, not an implementation. Second, do you analyse server logs on every engagement, or only Screaming Frog crawls? Logs are where crawl budget waste lives. Third, how do you verify Core Web Vitals fixes, per template or per origin? Per-origin scores hide template-level regressions. Any agency that cannot answer those concretely is selling commodity technical SEO.
