Technical SEO services.
Ongoing technical SEO for sites that keep shipping — crawl, render, index, and Core Web Vitals held to standard, release after release.
A technical SEO agency built for drift
Technical SEO services manage everything that decides whether a site can be crawled, rendered, indexed, and served fast — and keep those four things true while the site keeps changing. That second half is the actual job. Any competent shop can fix what's broken today. The work that compounds is making sure next month's release doesn't quietly break it again.
Because sites don’t fail once. They drift. A developer ships a new filter component and the crawl space triples. A CMS update rewrites canonical logic on two hundred templates. Marketing installs a script that adds 400 ms to every page’s input delay. None of these show up in the browser, nobody files a bug, and Search Console won’t complain for weeks. Ongoing technical SEO exists because the gap between “we fixed it” and “it stayed fixed” is where most organic traffic actually goes to die.
What our technical SEO services cover
Eight standing workstreams, each owned continuously rather than revisited annually:
- 01Reachcrawl · index
- 02Renderjs · dom
- 03Understandschema · entities
- 04Trustvitals · signals
Crawl management
budget allocation, parameter and facet control, redirect hygiene, orphan prevention. Large sites get log-file monitoring so we watch what Googlebot fetches, not what we assume it fetches.
Rendering QA
raw-versus-rendered DOM diffs whenever a template changes, so content and links that exist only after JavaScript are a known quantity, never a surprise.
Indexation control
coverage deltas tracked against a known-good baseline, declared canonicals reconciled with Google’s selections, noindex and robots directives enforced as configuration rather than folklore.
Core Web Vitals
field p75 per template, with every regression traced to the release that caused it. The bar is the one we publish and build to ourselves: LCP under 2.5 s, INP under 200 ms, CLS under 0.1.
Structured data
the JSON-LD graph kept valid and connected as entities, pages, and products change. One organization node, no orphan references, nothing asserted that the page doesn’t show.
Internal architecture
click depth to money pages, link equity routed where revenue is, pagination and hub structures that distribute instead of hoard.
Incident response
when traffic drops, triage with evidence: what changed, in which system, affecting which URL sets, confirmed against which data source.
Framework and platform specifics
Next.js and React rendering behavior, Shopify’s canonical and tag-page mechanics, WordPress plugin sprawl, headless setups where the CMS and the front end disagree about what exists.
Content-layer work — titles, intent alignment, entity coverage — isn’t on this list because it’s a different discipline with its own page: on-page SEO. And when findings need engineering muscle beyond fixes, our web development arm builds it. Same people, same standards, no translation loss. And when the target is being cited by answer engines rather than ranked by one, that layer is generative engine optimization — built on this foundation, never instead of it.

How the engagement runs
Every engagement follows the same five stages. The names never change; the depth of each stage scales to the site.
- 01Audit. We start with the full Six-Gate teardown — crawl, indexation, rendering, experience, structure, meaning — because retained work without a baseline is guesswork with a monthly invoice. If you’ve already bought the audit as a one-time engagement, this stage is done and the findings carry straight over.
- SEO Audit The full six-gate teardown opens every engagement.
- 02Scope. Findings become a written, fixed scope. We sequence fixes by traffic impact against implementation effort and match the plan to your release cadence, not an idealized one. What we won’t do is also in writing — a scope that only lists inclusions isn’t a scope.
- 03Implement. Fixes ship as ticket-ready specs your developers can execute, or we implement them ourselves through the web-development arm. Either way the spec exists first: current behavior, required behavior, affected templates, acceptance check. Nothing gets “handled” verbally.
- 04Verify. A fix isn’t done when it’s deployed. It’s done when Search Console shows the coverage change, the field data moves, and the crawl confirms the new behavior — on production, not staging. We close findings against evidence, and findings that don’t verify get reopened, not archived.
- 05Retain. The site keeps shipping, so the discipline keeps running. This stage has its own machinery, and it’s the reason retained clients stay retained.

Drift Watch — what Retain actually contains
Drift Watch is our standing cadence for catching regressions before Google prices them in. Releases get a pre-deploy pass on the surfaces that break silently: robots directives, canonical output, noindex flags, and a rendering diff on every changed template. Between releases, the watch runs on deltas — index coverage against baseline, CWV field p75 per template, crawl-stat anomalies, structured-data validity on anything the CMS touched. Log sampling continues on sites large enough for crawl budget to be a real constraint rather than a talking point.
The distinction that matters: monitoring tools alert on symptoms. Drift Watch attributes cause. When INP degrades, the finding names the script and the release that introduced it. When indexed pages jump by four thousand, the finding names the template minting them. Alerts without attribution just generate meetings.
Working with us
You get a direct line to the people doing the work. An accountable lead directs the engagement end to end — no account-manager relay, no work lost in hand-offs, no re-explaining your stack every quarter. Questions go to an engineer who has your crawl data open, and answers come back with evidence attached.
Retainers run at a flat monthly rate against the written scope. Project-shaped work — a migration risk assessment before a replatform, a one-time teardown — is quoted as a fixed scope with a fixed number. Nothing is metered hourly, and you’ll never find a pricing page here because the honest number depends on your site, and we’d rather look at it first.
We work remote, worldwide, and async-first — which in practice means your time zone gets findings in writing with the evidence linked, not a calendar invite for everything.
Technical SEO FAQ
What are technical SEO services?
Technical SEO services are the ongoing management of a site’s search infrastructure — crawlability, rendering, indexation, performance, and structured data — as opposed to its content. The distinction from a one-time audit is continuity: the service exists because sites regress with every release, and catching regressions early is cheaper than diagnosing traffic drops late. Ours runs as eight standing workstreams under a five-stage engagement, with fixes verified in Search Console and field data before they’re closed.
How do I choose the right technical SEO agency?
Ask who you’ll actually talk to, and ask to see one finding from a real engagement. The finding tells you whether you’re buying diagnosis or tool exports — it should carry evidence, affected URLs, and a spec a developer could ship. The access question tells you whether the people selling the work are the people doing it. Then ask how they verify fixes: “we deployed it” and “Search Console confirmed it” are different answers, and only one of them is the job.
How does working with a technical SEO agency work?
It starts with a full teardown and runs as a retained cadence afterward. In our case: a Six-Gate baseline, a written fixed scope sequenced by impact, implementation through your developers or ours, verification against index and field data, then Drift Watch — pre-release checks and delta monitoring as the site keeps changing. Communication is direct and written; you always know what was found, what shipped, and what the data did next.
How is technical SEO different from on-page SEO?
Technical SEO governs infrastructure — whether pages can be crawled, rendered, indexed, and served fast. On-page SEO governs the content layer — whether pages match intent, cover their entities, and earn the click. They fail independently: a perfectly optimized page on a broken stack stays invisible, and a flawless stack can’t rescue content nobody searched for. We run them as separate disciplines with a shared boundary, which is why each has its own page here.
