Technical SEO

The structural work that compounds.

The infrastructure layer of search — crawlability, rendering, indexation, schema, performance. Invisible when it works. Painfully visible when it doesn’t. We do the careful, methodical work that turns a site into one search engines can read, trust, and rank.

01 — What’s Included

Nine sub-techniques.
One honest foundation.

Technical SEO is not a single deliverable. It is a coordinated set of audits, fixes, and configurations that together determine whether a search engine can crawl your site efficiently, render your pages correctly, and decide they are worth ranking.

Every engagement begins with a full technical audit, every fix is documented, and every change is verified in Search Console once it has propagated.

N° 01

Crawlability

Foundational

Whether Googlebot, Bingbot, and the AI crawlers can discover and access every page worth ranking. We audit the site’s internal link graph, surface orphan pages, identify broken redirect chains, fix redirect loops, and tune crawl budget for larger sites so important pages are visited in the right rhythm. For sites with millions of URLs, this work alone is the difference between a healthy index and a slow rot. We use Screaming Frog for full-site crawls, Search Console crawl-stats for verification, and log-file analysis where the situation warrants it.

N° 02

Core Web Vitals & Performance

User experience

Google’s three field metrics — Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift — are now genuine ranking signals, and they are what your visitors actually feel. We measure your real-user data through CrUX, identify the bottlenecks, and resolve them at the source: image optimisation, deferred JavaScript, font loading strategy, server response times, render-blocking CSS, and layout-shift causes like late-loading ads or unsized images. Performance work overlaps with our hosting and CDN advice, and we coordinate accordingly.

N° 03

Indexation Management

Inventory control

Not every page on your site should be indexed, and not every page that should be indexed currently is. We audit the indexed inventory in Search Console, identify thin or duplicate pages that dilute topical authority, set up the right combination of noindex, canonicalisation, and consolidation, and remove low-value URLs from search. The result is a leaner, more confident index where every URL Google holds is one that earns its place — and the average page-quality signal across your domain rises accordingly.

N° 04

Structured Data & Schema

Machine-readable

JSON-LD schema is how you tell search engines what your content actually is — an article, a product, a local business, a legal service, a FAQ. We implement the right schema for each page type, validate it against Google’s tests, and monitor for rich-result eligibility. Beyond rich snippets, structured data is increasingly the connective tissue between your content and the AI search layer: when an LLM cites your page, it is often because the schema made the entities and relationships unambiguous.

N° 05

XML Sitemaps

Discovery

A clean, accurate XML sitemap is the single best signal a site can give a search engine about which URLs are canonical and worth crawling. We build sitemaps that reflect only indexable, canonical URLs, segment by content type for larger sites, set sensible lastmod values that update on real content changes, and reference them from robots.txt and Search Console. We also remove the noise that plugin-generated sitemaps tend to accumulate — paginated archives, parameter URLs, and stub pages that confuse rather than clarify.

N° 06

Robots Directives

Access control

The robots.txt file and meta-robots tags are deceptively simple and easy to misuse. We audit your existing directives, identify the disallowed-yet-indexed URLs that are leaking through, and configure access rules that match the site’s actual content strategy. We also tune access for the new generation of AI crawlers — GPTBot, Google-Extended, ClaudeBot, PerplexityBot — so your content shows up where you want it cited and stays out of training corpora you would rather opt out of.

N° 07

Canonical Tags

Consolidation

Duplicate and near-duplicate URLs are unavoidable on most sites — pagination, faceted navigation, tracking parameters, HTTPS variants, trailing-slash inconsistencies. Without correct canonical signals, Google has to guess which version is the real one, and it does not always guess in your favour. We audit canonical implementation across the site, fix self-referential errors, resolve conflicts between canonical tags and other directives, and consolidate ranking signals onto the URLs that actually matter.

N° 08

Mobile-First Readiness

Index parity

Google has indexed the mobile version of your site as the primary version for several years now. That means anything missing from the mobile rendering — content hidden behind unexpanded accordions, structured data that only renders on desktop, internal links that disappear at smaller breakpoints — is effectively missing from search. We audit mobile-desktop parity, ensure the mobile experience is genuinely complete rather than stripped down, and fix the responsive-CSS issues that most often hide content from the mobile crawler.

N° 09

JavaScript Rendering

Modern web

Single-page applications, headless front-ends, and JavaScript-heavy themes all create the same risk: content that loads for users but never reaches the search index. We test your site through Google’s URL Inspection tool, mobile-friendly test, and dedicated rendering crawls to confirm what is actually indexable. Where rendering fails, we work with your developers on the fix — server-side rendering, dynamic rendering for crawlers, or static-generation hydration — depending on the stack and the constraint.

02 — Our Approach

Audit. Prioritise.
Fix. Verify.

Technical SEO benefits more than most disciplines from a disciplined sequence. We do not start fixing until we know what is broken, we do not move on until we have confirmed the fix landed, and we do not declare victory based on a tool’s all-green dashboard.

i

Full audit before any fix

The first deliverable is a written technical audit covering crawlability, indexation, performance, schema, sitemaps, and rendering. Every issue is documented with its location, its severity, the evidence we used to identify it, and the recommended remediation. We work from this document — not from a dashboard — and you keep it as a reference long after the engagement ends.

ii

Prioritised by ranking impact

Not every technical issue is worth fixing today. We rank findings by their likely impact on rankings and indexation, the effort required to fix them, and the risk of leaving them in place. The first month focuses on the small number of high-impact items that move the needle. Lower-priority items are documented for future passes rather than padding an inflated invoice.

iii

Implementation, not just recommendations

We do the work, not just the report. Most issues are fixed by us directly — schema deployment, sitemap regeneration, robots tuning, redirect cleanup, performance work. Where a fix needs your developer or hosting provider, we write a clear specification and stay involved through QA. The audit document itself does not lift rankings; the executed fixes do.

iv

Verified in Search Console

Every fix is followed up in Search Console once the change has had time to propagate — typically two to four weeks. We confirm crawl errors clear, indexation moves in the right direction, Core Web Vitals shift on real-user data, and rich-result eligibility appears where expected. If a fix did not land, we revisit it. No item is closed without verification.

03 — Who It’s For

Sites where the
foundation is leaking.

Technical SEO is the right starting point for any site where good content already exists but rankings have stalled, dropped, or never quite materialised. It is also the necessary first step before any content or link-building investment will produce its full return.

A few recurring profiles where the structural fix is the unlock.

  • i Sites that have lost rankings without a clear reasonSometimes the cause is an algorithm update; often it is a quiet technical drift — a botched redeploy, a corrupted sitemap, a CDN change that broke rendering. A technical audit surfaces what changed.
  • ii Sites preparing for a redesign or migrationMigrations multiply technical debt. Doing the audit before the migration means the new site launches without inheriting the old one’s structural problems — and without losing accumulated equity in transit.
  • iii JavaScript-heavy sites and SPAsAnything built on React, Vue, Next.js, or a headless CMS where content is hydrated client-side. Rendering parity, indexation completeness, and Core Web Vitals all need verification — not assumption.
  • iv Larger sites with crawl-budget concernsE-commerce catalogues, faceted-navigation systems, programmatic content, news archives. When a site has tens of thousands or millions of URLs, crawl efficiency becomes a meaningful ranking input.
  • v Sites that have invested in content without seeing returnsIf you have published consistently for a year and the traffic curve has not bent, the bottleneck is rarely the content itself. It is usually a crawl, indexation, or rendering issue suppressing the work that has already been done.

Technical SEO is also a prerequisite for AI search visibility. The same structural cleanliness that helps Google index a page makes it easier for an LLM to read, cite, and surface that page in a conversational answer. The investment serves both channels at once.

05 — Frequently Asked

Questions we get
about technical SEO.

If a question is missing here, the contact link at the foot of the page goes straight to the person who would answer it. No ticket queues, no funnels.

i How is technical SEO different from on-page SEO?
On-page SEO is about the content of a given page — the title, the headings, the body copy, the internal links — and how clearly it signals what the page is about and who it serves. Technical SEO is about whether search engines can reach that page at all, render it correctly, and decide it is canonical. The two work together: brilliant on-page work cannot rank a page that Googlebot cannot crawl, and a flawless technical foundation will not lift rankings on a page with thin content. Most sites need both, but technical issues need to be resolved first because they cap the ceiling of every other investment.
ii Do I need a technical audit if my site looks fine and ranks reasonably well?
Often, yes. A site that ranks reasonably well despite technical issues is a site that is leaving rankings on the table. The most common pattern we see is a domain with strong content and decent authority being held back by a handful of crawl, indexation, or rendering issues that nobody has caught because the site has never been audited end to end. Even a clean site benefits from a periodic audit — every redeploy, plugin update, theme change, and CMS upgrade is an opportunity for new technical debt to creep in. A baseline audit every twelve to eighteen months is sensible insurance.
iii How long does a technical SEO engagement take?
A standard initial engagement runs four to eight weeks. Week one is the audit. Weeks two and three are remediation of the high-priority items. Weeks four and beyond are verification, monitoring, and the second pass on lower-priority issues. The verification window is important — Google can take two to four weeks to recrawl, reprocess, and reflect changes in Search Console, so we deliberately leave that runway in the schedule. Larger or more complex sites can run longer; a focused single-issue engagement (Core Web Vitals only, schema only, migration prep) can run shorter. We scope honestly upfront based on the audit findings.
iv Will technical SEO improve my Core Web Vitals scores in PageSpeed Insights?
Yes, where the diagnosis is correct. A common mistake is to optimise for the synthetic Lighthouse score in PageSpeed Insights rather than the field data Google actually uses for ranking. The synthetic score is useful as a debugging tool; the field data — drawn from real Chrome users via the Chrome User Experience Report — is what counts. We work against both, but we prioritise the issues that show up in field data because those are the ones that affect real visitor experience and real ranking signals. The lab number tends to follow the field number once the underlying problems are fixed.
v Can technical SEO recover a site that has lost rankings?
Often, but not always — and the honest answer depends on what caused the drop. If the cause is a technical issue introduced by a redeploy, plugin change, hosting migration, or CMS update, recovery is usually straightforward once the underlying problem is identified and reversed. If the cause is an algorithm update that shifted how Google evaluates content quality, technical fixes alone will not recover the rankings; the content itself needs work. The audit will tell you which scenario you are in. We do not promise recovery upfront — we diagnose first, then advise on whether the right intervention is technical, editorial, or both.
vi Do you handle the implementation, or do we need our developers?
We handle most of it directly. Schema deployment, sitemap regeneration, robots configuration, redirect cleanup, canonical tag fixes, image optimisation, performance tuning — all of this we do ourselves. Where a fix requires deeper access to your codebase or infrastructure — for example, server-side rendering changes on a custom application, or hosting-level configuration — we write a precise specification for your developers and stay involved through implementation and QA. We never throw a fifty-item PDF over the wall and consider the engagement done.
