Technical SEO Services That Fix What’s Actually Blocking You
Great content on a broken site produces nothing. We find the technical issues stopping Google from crawling, rendering and ranking your pages — and we fix them, not just report them.
We Fix It, We Don’t Just Flag It
Most technical audits are 90-page PDFs that sit in a folder. We deliver a prioritized fix list — and because we build in WordPress and Next.js in-house, we can implement it too.
What Is Technical SEO?
Technical SEO is the work that makes your website crawlable, renderable, indexable and fast — so search engines can actually access and understand what you’ve published.
It’s the foundation everything else sits on. You can have the best content in your industry, but if Google can’t crawl it, can’t render it, or gives up because your server is slow, none of it ranks.
It’s invisible. Content is a deliverable you can see. Backlinks are a number that goes up. Technical SEO is a set of problems that, when solved, produce… nothing visible. The site just works.
Which is exactly why it’s where most underperforming campaigns are actually stuck. We regularly audit sites that have been paying for content and links for two years while a single indexation problem quietly prevented half their pages from ranking at all.
Crawlability
Can Googlebot reach your pages? Robots.txt rules, internal linking, orphan pages, crawl traps from faceted navigation or calendars.
Indexability
Once crawled, do pages get indexed? Noindex tags, canonical conflicts, duplicate content, thin pages consuming index budget.
Rendering
If your site relies on JavaScript, does Google see your content? This is the most common invisible failure on modern sites — the page looks fine in a browser and is largely empty to a crawler.
Site speed and Core Web Vitals
Largest Contentful Paint, Cumulative Layout Shift, Interaction to Next Paint. Direct ranking factors and direct conversion factors.
Site architecture
How pages connect, how deep important content sits, how authority flows internally.
Structured data
Schema markup that tells search engines and AI models what your content means rather than making them infer it.
International and mobile
Hreflang correctness, mobile-first indexing, responsive implementation.

Our Technical SEO Services
Technical SEO audit
Full crawl, log file analysis where available, rendering tests, Core Web Vitals field and lab data, indexation review, and competitive technical benchmarking.
Core Web Vitals optimization
LCP, CLS and INP fixed at the cause: render-blocking resources, image delivery, layout stability, JavaScript execution, and server response time.
Crawl budget optimization
Log file analysis to see what Googlebot actually crawls, then eliminating waste — crawl traps, duplicate parameters, low-value pages consuming budget.
JavaScript SEO
Rendering diagnosis for React, Vue, Angular and headless builds. Server-side rendering, dynamic rendering, or hydration fixes depending on what your stack supports.
Schema & structured data
Complete implementation across page types, validation, conflict resolution, and coverage designed for both rich results and AI retrieval.
Site architecture & internal linking
Flattening deep hierarchies, fixing orphan pages, redistributing internal authority toward pages that convert.
Migration support
Replatforms, domain changes, HTTPS moves, URL restructures. Redirect mapping, pre-launch testing, and post-launch monitoring.
International technical SEO
Hreflang implementation and validation, geo-targeting, and multi-region indexation.
How We Prioritize
Most audits list a hundred issues with no guidance on sequence. That’s how audits end up unimplemented.
We rank everything on two axes: impact and effort. Then we sequence:
That last category is the one most agencies won’t give you, because listing more problems looks like more value.

Technical SEO Services That Fix It, Not Just Flag It
Most technical audits are ninety page PDFs that get opened once and filed. We deliver a prioritized fix list, tell you what to ignore, and because we build in WordPress and Next.js in house, we can implement it too.
We Tell You What Not to Fix
Most audits list every issue a crawler can find, because more problems looks like more value. We rank by impact and effort, then explicitly name the items that are not worth your developer time.
What Is Technical SEO?
Technical SEO is the work that makes your website crawlable, renderable, indexable and fast, so search engines can actually access and understand what you have published.
It is the foundation everything else sits on. You can have the best content in your industry, but if Google cannot crawl it, cannot render it, or gives up because your server is slow, none of it ranks.
Why technical SEO gets skipped
It is invisible. Content is a deliverable you can read. Backlinks are a number that goes up. Technical SEO is a set of problems that, once solved, produce nothing visible. The site simply works.
Which is exactly why it is where most underperforming campaigns are stuck. We regularly audit sites that have paid for content and links for two years while a single indexation problem quietly prevented half their pages from ranking at all.
The three pillars
A page that looks fine in your browser can be almost empty to a crawler.
The seven areas we cover
Crawlability
Robots.txt rules, internal linking, orphan pages, crawl traps generated by filters, calendars or session parameters.
Indexability
Noindex tags, canonical conflicts, duplicate content, and thin pages consuming index budget that should go elsewhere.
Rendering
JavaScript content invisible to crawlers. The most common silent failure on modern sites, and often unnoticed for years.
Speed and Core Web Vitals
LCP, CLS and INP failures caused by render-blocking resources, heavy templates and slow server response.
Site architecture
Important pages buried five clicks deep, authority trapped in the wrong places, internal links pointing nowhere useful.
Structured data
Missing, invalid or contradictory schema across plugins, themes and templates fighting each other.
International and mobile
Broken hreflang, mobile-first indexing problems, and responsive implementations that fail on real devices.
What Technical Problems Actually Cost You
Pages that never rank because Google never sees them. Crawl traps, orphan pages and indexation errors can leave entire sections invisible while you keep paying to add more.
Content investment producing nothing. Publishing on a technically broken site is pouring water into a leaking bucket. The content is fine. The delivery is broken.
Rankings you had and lost. Deployments introduce regressions. Plugins conflict. Redirect chains form. Most technical debt accumulates quietly between audits, and rankings decay before anyone notices.
AI invisibility. AI engines rely on clean rendering and structured data to retrieve and cite content. A site they cannot parse does not get cited, regardless of how good the writing is.

How We Prioritize, Including What to Ignore
Most audits list a hundred issues with no guidance on sequence. That is precisely how audits end up unimplemented. We rank everything on two axes, impact and effort, then sort into four buckets.
High impact, low effort
Ship this week. These are the changes that produce visible movement fastest, usually because you are unblocking pages Google already wanted to rank.
High impact, high effort
Worth doing, needs scoping. We write these as developer-ready specifications with acceptance criteria so they can enter a sprint without translation.
Low impact, low effort
Bundle into a maintenance sprint. Individually trivial, collectively worth an afternoon.
Low impact, high effort
We say so explicitly. This is the bucket most agencies will not give you, because listing more problems looks like more value even when it wastes your budget.

Our Technical SEO Services
Scoped to your platform, site size and where the actual constraint sits. We audit before we propose, always.
Full technical audit
Complete crawl, rendering tests across every template, Core Web Vitals field and lab data, indexation review, schema validation and competitive benchmarking.
Core Web Vitals optimization
LCP, CLS and INP fixed at the cause. Render-blocking resources, image delivery, layout stability, JavaScript execution and server response time.
Log file analysis
What Googlebot actually crawls, rather than what a tool guesses. The only way to see crawl budget waste on a large site.
JavaScript SEO
Rendering diagnosis for React, Vue, Angular and headless builds, then server-side rendering, static generation or hydration fixes depending on your stack.
Schema and structured data
Complete implementation across page types, conflict resolution between plugins and themes, and validation sitewide.
Architecture and internal linking
Flattening deep hierarchies, fixing orphan pages, and redistributing internal authority toward pages that convert.
Migration support
Replatforms, domain changes, HTTPS moves and URL restructures with redirect mapping and staged testing.
International technical SEO
Hreflang implementation and validation, geo-targeting configuration and multi-region indexation.
Continuous monitoring
Automated alerting so regressions surface in days rather than at the next quarterly review.
Technical SEO for AI Search
AI engines have their own requirements
AI retrieves passages, not pages. A model does not rank your article, it extracts a chunk of it. Whether that chunk stands alone is a structural question, and structure is technical work.
AI often cannot render what Googlebot eventually can. If your content requires JavaScript execution to appear, many AI crawlers will never see it at all.
Structured data is how AI knows what content means. Without schema a model has to infer. With it, the meaning is explicit and citable.
Crawler access, configured deliberately
Each obeys robots.txt independently. Most sites have never made this a decision rather than an accident.
Server-side rendering or static generation so content exists in the initial HTML response rather than after execution.
Organization, Service, FAQPage, Article, Breadcrumb and Product where relevant, implemented cleanly and checked sitewide.
Headings that describe meaning rather than styling, proper landmark elements, and content that chunks cleanly for retrieval.
Emerging standards for declaring what AI systems may access and how your content should be understood.
