Technical SEO

Technical SEO Services

The invisible plumbing that decides whether Google can rank you at all

You can write the best content in your market, earn the best links, and still lose — because Google can't crawl the page, can't index it, or gives up before it loads. Technical SEO is the layer nobody sees and every ranking depends on. It's also the layer most agencies quietly skip, because fixing it means touching your code, and they can't.

Why it matters

Google's crawler is the gatekeeper standing in front of every ranking

Before a page can rank, Google has to do four things in order: discover it, crawl it, render it, and index it. Every one of those stages is a filter, and every one can silently drop your page before ranking is even on the table. Content and links are what most people obsess over — but they live downstream of a crawler that has to actually reach the URL, load the JavaScript, and understand what's on the page.

That's why technical SEO is the least glamorous work in the field and the most neglected. It doesn't produce a shiny blog post you can show a client. What it produces is a site Google can read completely and quickly — which is the precondition for everything else you're paying for to work.

It's also the highest-leverage work there is. A single fix to a page template, a canonical rule, or a crawl directive can correct thousands of URLs at once. Get the plumbing right and every future piece of content inherits a foundation that actually ranks.

The full scope

Everything that lives under technical SEO

Make sure Google can find, reach, and keep every page that matters

Half of technical SEO is getting Google to see the right pages and ignore the wrong ones. We run log-file analysis to see exactly how Googlebot spends its crawl budget on your site, then clear the traps that waste it — infinite faceted URLs, session parameters, orphan pages nobody links to, and pages accidentally blocked by robots.txt or a stray noindex.

  1. Log-file analysis of real Googlebot behavior
  2. Crawl-budget recovery on large and e-commerce sites
  3. XML sitemap and robots.txt cleanup
  4. Orphan-page discovery and internal-link repair
  5. Accidental noindex / canonical audits

Real fixes to real speed problems — not a plugin and a prayer

Core Web Vitals are a ranking factor and, more importantly, the difference between a visitor who converts and one who bounces before the page even paints. We diagnose LCP, INP, and CLS at the code level: render-blocking resources, oversized images, layout shift from ads and fonts, and bloated JavaScript bundles — then we actually ship the fixes.

  1. LCP, INP, and CLS diagnosed at the code level
  2. Render-blocking CSS/JS elimination
  3. Next-gen image formats, lazy-loading, and CDN setup
  4. JavaScript bundle reduction and caching strategy

Markup that earns rich results and feeds AI Overviews

Structured data is how you tell Google exactly what a page is instead of making it guess. Done right, it wins rich results — star ratings, FAQs, product pricing, breadcrumbs — that steal clicks from higher rankings, and increasingly it's what makes your content eligible to be cited in AI Overviews and answer engines.

  1. JSON-LD for Product, FAQ, Article, LocalBusiness, and more
  2. Rich-result eligibility and validation
  3. Entity and organization markup for knowledge panels
  4. Schema that feeds AI Overviews and answer engines

Internal linking and canonicalization that stops your pages competing with each other

A big site with no architecture is a big site fighting itself. We map internal linking so authority flows to the pages that should rank, kill the duplicate and near-duplicate URLs cannibalizing each other, and set canonical and pagination rules so Google consolidates signals instead of splitting them.

  1. Internal-link maps that route authority to money pages
  2. Canonicalization and duplicate-content resolution
  3. Faceted-navigation and pagination handling
  4. URL-structure and taxonomy cleanup

Replatform or redesign without torching your rankings

Migrations are where rankings go to die — one botched redirect map and years of equity vanish overnight. We plan the whole move: full URL inventory, 1:1 redirect mapping, staging QA against a technical checklist, and day-one monitoring so anything that slips is caught in hours, not months.

  1. Complete URL inventory and 1:1 redirect mapping
  2. Staging QA against a full technical checklist
  3. Parity checks on metadata, schema, and internal links
  4. Day-one crawl monitoring and rollback readiness

How we work

How a Swarm technical engagement runs

01

We crawl your site the way Google does

A deep technical crawl plus log-file analysis of real Googlebot behavior. We map every reachable URL, every error, and every place crawl budget or link equity is leaking.

Full technical crawl

Every URL, status code, canonical, and directive on the site.

Log-file analysis

How Googlebot actually spends its time on your site.

Core Web Vitals baseline

Field and lab data for LCP, INP, and CLS.

02

We rank every fix by impact versus effort

Not all technical debt is worth paying down. We sort findings into what moves rankings now, what protects you later, and what can wait — so you never spend a budget on cosmetic fixes.

Impact scoring

Each issue tied to the pages and keywords it affects.

Effort estimate

Honest scope so quick wins ship first.

A shared fix log

One living list you can watch us work through.

03

We make the changes — in your codebase

This is the step other agencies can't do. We write and ship the fixes ourselves, tested in staging first, so recommendations turn into deployed changes instead of a PDF gathering dust.

Staging first

Every change tested before it touches production.

Real code changes

Templates, redirects, schema, and performance — done, not described.

Careful rollout

Migrations and high-risk changes shipped with a rollback plan.

04

We re-crawl, monitor, and prove it moved

A fix you can't measure is a fix you can't trust. We re-crawl, watch Search Console, and report the before-and-after so you can see exactly what changed and what it earned.

Re-crawl and validate

Confirm the fix resolved and nothing regressed.

Search Console tracking

Indexation, impressions, and Core Web Vitals over time.

Ongoing monitoring

New technical debt caught before it costs you.

The difference

We’re the developer — so the fixes actually get made

Most SEO agencies hand you a report of technical problems and tell you to go find a developer. We are the developer. That's the whole difference — the audit doesn't end in a PDF, it ends in fixes that are live on your site. If your rankings are stuck despite good content, the plumbing is usually why.

By industry

Technical SEO looks different in every industry

E-commerce

Large catalogs are technical minefields: faceted navigation spawns millions of crawlable URLs, product variants duplicate content, and pagination buries your best sellers.

We tame crawl budget with parameter handling and canonicalization, add Product and Review schema for rich results, and keep pagination and out-of-stock logic from leaking equity — so Google spends its crawl on pages that actually sell.

Local & Multi-Location

For local and franchise brands, architecture is everything: hundreds of location pages have to be crawlable, internally linked, and marked up consistently or they cannibalize each other.

We build location-page architecture that scales, keep NAP and LocalBusiness schema consistent across every branch, and route internal links so each market page can rank in its own city.

Learn more

SaaS & Tech

SaaS sites lean on JavaScript frameworks that Google struggles to render, and their docs and programmatic pages often number in the tens of thousands.

We fix JS rendering and hydration issues so content is actually indexed, structure documentation for crawlability, and make programmatic page templates that scale without tripping thin-content or duplicate filters.

Healthcare

Healthcare is YMYL — Google holds it to a higher trust bar, and content-heavy medical sites are often slow and hard to crawl.

We shore up page speed on heavy content, implement MedicalOrganization and author markup that signals expertise, and keep the site architecture clean so trust signals consolidate instead of scattering.

Learn more

Legal

Law firms build huge libraries of practice-area and location pages that look near-identical to Google and quietly compete for the same rankings.

We resolve that cannibalization with canonicalization and internal-link strategy, differentiate templated pages, and add the schema that helps individual attorney and practice pages stand on their own.

Learn more

Real Estate

Listing sites carry enormous, constantly-changing inventories — the classic crawl-budget and index-bloat problem, made worse by expired listings.

We handle expired and out-of-inventory URLs cleanly, prioritize crawl budget toward active listings and money pages, and keep the sitemap and internal linking in sync with a database that never stops moving.

Common questions

Frequently Asked Questions

How do I know if I have technical problems?

The usual tells: traffic is flat or sliding despite good content, pages you publish never show up in Google, load times are slow, or Search Console is flagging coverage and Core Web Vitals issues. The fastest way to know for sure is the free technical audit — we crawl the site and show you exactly what's wrong.

Will these changes break my site?

No. Every change is tested in a staging environment before it touches production, and high-risk work like migrations ships with a rollback plan and day-one monitoring. We're engineers — safe deployment is how we work by default.

Why can you do this when my current SEO agency can't?

Most SEO agencies are marketers who can identify technical problems but can't fix them — they hand you a report and tell you to find a developer. We're engineers who do SEO, so we write and deploy the fixes ourselves. The work actually gets done.

Is technical SEO a one-time project or ongoing?

The big foundational fixes are largely one-time — clean them up once and every future page benefits. But technical debt accumulates as your site grows, plugins update, and Google changes its thresholds, so we monitor and catch new issues before they cost you rankings.

How does technical SEO affect AI Overviews and answer engines?

Heavily. AI Overviews and answer engines can only cite content they can crawl, render, and understand — the same technical foundation that helps you rank in classic search is what makes you eligible to appear in AI answers. Clean structured data and crawlability are increasingly the price of entry.

How long until I see results?

Speed and crawlability fixes can show up in weeks as Google re-crawls and re-indexes. Bigger architecture and migration work compounds over months. We track it all in Search Console so you can watch indexation and rankings respond to each fix.
