/ Technical SEO services for sites Google struggles to read
Technical SEO services that fix the root cause.
Our technical SEO services find out what Google actually crawls, renders and keeps on your site, then remove what stands in the way: indexing gaps, JavaScript rendering, slow templates, broken redirects. We ship the fixes on Shopify, WordPress or Webflow, or hand your developers tickets they can build.
Findings from your actual site, checked by hand. Not a 300-row tool export.
Choosing who to hire? Technical SEO agency: how we work
Illustrative growth curve. The totals are real, rounded down, across four stores using our SEO playbook.
Each fix recrawled and confirmed/ Sound familiar?
Good pages. Google can't see them.
Technical problems rarely announce themselves. Traffic slides, new pages never appear, and the cause sits in a template, a header or a script nobody has opened in years.
Pages stuck as not indexed
Search Console lists thousands of URLs as crawled or discovered but not indexed, and nobody on the team can say which ones matter or why it happens.
Content that only exists after JavaScript
Product text, prices and links load client side. Google renders later and sometimes only partly, and links built as buttons are never followed at all.
Traffic never recovered from the relaunch
A redesign or replatform went live with missing or chained redirects. The old URLs held the links and rankings, and the new ones started from zero.
Templates that fail Core Web Vitals
Oversized hero images, tag managers and chat widgets push mobile load times past Google's thresholds. Rankings slip a little, and conversion rates slip a lot.
We begin with what Googlebot really does on your site, not with what a tool score says.
/ What's included
What our technical SEO services cover, layer by layer.
We work from the bottom up. Speeding up a page Google refuses to index is wasted effort, so crawl control comes first and polish comes last.
Crawling & indexing
Every engagement in our technical SEO services starts with control over which URLs Google finds, crawls and keeps. We make robots.txt, XML sitemaps, canonicals, noindex tags and internal links all give the same answer.
Why it matters: mixed signals, like a canonical pointing at a noindexed URL, force Google to guess, and it often guesses against you.
- The Search Console page indexing report worked through reason by reason
- XML sitemaps that list only indexable, canonical URLs
- Robots.txt rules tested against what you want crawled
- Redirect chains, loops and soft 404s removed
- Parameter, session and duplicate URLs consolidated
- Filter and variant rules via our ecommerce SEO services
Rendering & JavaScript
React, Vue, Angular and Next.js sites often look complete to visitors and half empty to crawlers. We compare the raw HTML response with the rendered page for each template and close the gaps that cost you rankings.
Why it matters: if main content or links appear only after client-side scripts run, every page depends on Google rendering it correctly.
- Raw HTML and rendered DOM compared template by template
- Navigation and pagination built as real anchor links
- Server-side rendering or prerendering where it pays off
- Lazy-loaded content and infinite scroll made crawlable
- Blocked JavaScript and CSS resources found and released
- Empty shells and hydration errors flagged to your developers
Speed & Core Web Vitals
We work on Largest Contentful Paint, Interaction to Next Paint and Cumulative Layout Shift using field data from real Chrome users, grouped by template. Lab scores help us debug. Field data decides what we fix first.
Why it matters: rankings use field data, so a page can pass a Lighthouse test and still fail for most of your mobile visitors.
- Field data from CrUX and Search Console, split by template
- Hero images sized, compressed and given fetch priority
- Render-blocking CSS and JavaScript trimmed
- Third-party tags and apps audited, deferred or removed
- Layout shifts from fonts, banners and embeds fixed
- Caching, CDN and image delivery settings reviewed
Architecture & structured data
Structure tells Google which pages matter. We cut click depth to your revenue pages, link orphaned URLs back in, tidy URL patterns and add structured data that matches what visitors actually see.
Why it matters: a page five clicks deep with two internal links rarely ranks, however well it is written.
- Click depth and internal link flow mapped per section
- Orphan pages found and linked from relevant hubs
- Consistent URL patterns and breadcrumb trails
- Product, Article, FAQ and breadcrumb schema validated
- Hreflang handled with our international SEO services
- Pagination that keeps deep catalogue pages reachable
Migrations & log files
A migration is where technical work earns its fee, or where skipping it costs the most. We map every URL before launch and verify every redirect after. Server logs then show where Googlebot really spends its time.
Why it matters: logs are the only record of what Googlebot actually requested, and no crawler can reproduce that for you.
- URL-by-URL redirect map signed off before launch
- Staging crawled and diffed against the live site
- Launch-day checks on redirects, robots.txt and canonicals
- Indexing and rankings watched for weeks after go-live
- Googlebot requests analysed from raw server logs
- Crawl waste on junk URLs cut and redirected
/ How it works
From diagnosis to deployed fixes.
A technical SEO project only counts once changes are live. Here is the path from findings to shipped, verified fixes.
Crawl and collect
A rendered crawl of the full site, Search Console and Core Web Vitals data, and your server logs if you can share them.
You get: a clear view of what Google crawls against what you want indexed.
Diagnose and rank
Each issue checked by hand, traced to a template, plugin or setting, and ranked by the traffic and revenue it puts at risk.
You get: a ranked fix list with tickets ready for development.
Ship and verify
We implement on Shopify, WordPress or Webflow, or work through your developers' sprints, then recrawl to confirm each fix held.
You get: the first fixes live within two weeks of kickoff.
Protect
Pre-release crawls of staging, regular log reviews and indexing checks, so new features and content don't undo the work.
You get: a site that stays technically healthy as it grows.
/ Results
Clean foundations, compounding clicks.
Technical fixes are the first thing our SEO playbook ships. Here is what that playbook delivered across four ecommerce stores over 16 months, with technical work running alongside content and links.
SEO, across four stores
16 monthsclicks from Google, without paying for a single one
One of these stores now makes 20 to 30 sales every week from search alone.
Our clients' data stays theirs, so we show rounded totals rather than their dashboards.
/ Is this for you?
Technical SEO services for sites like these.
✓A great fit if you are
- A large or fast-growing site with thousands of URLs or many templates
- Built on a JavaScript framework such as React, Vue or Next.js
- Planning a migration or redesign and determined to keep your rankings
- Running an in-house dev team that needs SEO requirements it can build to
- Seeing pages stuck as not indexed with no clear cause in Search Console
✕Probably not a fit if you
- Run a small, healthy site. Our SEO audit services may be all you need
- Can't deploy any changes. Technical SEO only works when fixes ship
- Want a perfect Lighthouse score. We fix what affects real users and rankings
- Mostly lack content or links. Technical work alone won't close that gap
/ Before you choose
What a good technical SEO service should include.
Most proposals look alike on paper. These details separate a technical SEO service that changes your rankings from one that produces a long report and stops. Use them to compare any offer, ours included.
Findings tied to templates, not URLs
A list of 4,000 URLs with missing tags is noise. A useful report names the template causing it, how many pages it affects and the traffic on them, so one fix closes the whole group.
A ranked order, with reasons
Every issue should carry an estimate of impact and effort. If the top item is missing alt text while half your products are not indexed, the priorities came from a tool, not a person.
Tickets your developers can build
Ask to see a sample ticket. It should state the problem, the evidence, the exact change, the affected templates and how to test it on staging. Advice like 'improve site speed' never ships.
Rendering checked, not assumed
If your site runs on React, Vue or Next.js, the offer should mention comparing raw and rendered HTML. Otherwise nobody has checked whether Google sees your content at all.
Verification after every release
Fixes regress. Themes update, plugins change, developers refactor. A serious service recrawls after release and confirms the change held, instead of closing the ticket the moment it is merged.
A clear plan for migrations
Ask whether a redesign or replatform is covered, and how. You want a full redirect map, a staging crawl and monitoring after launch. Our technical SEO company page explains how we cover them over time.
If an offer can't answer these points, a cheap audit tool will tell you just as much.
/ Your options
Tool, developers, agency, or us?
Technical SEO can be handled several ways. Here's where each one is strong and where it falls short.

|---|---|---|---|---|
| Finding issues | Hundreds of warnings, no context | Fix what they're told about | Tool export plus commentary | ✓Checked by hand, ranked by cost |
| JavaScript rendering | Partial, depends on settings | Know the code, less so how Google renders it | Varies by team | ✓Raw and rendered HTML compared per template |
| Migrations | Not covered | Focused on launch, less on redirects | Usually a redirect spreadsheet | ✓Full URL map, staging crawl, post-launch checks |
| Implementation | None | Yes, in their own sprints | Often recommendations only | ✓Directly, or tickets your developers can ship |
| Cost | Low monthly subscription | Developer time | Varies widely | ✓Fixed quote after the free audit |
