Technical SEO removes silencers: blocked resources, chaotic canonicals, slow LCP, soft 404s, and schema that lies. Without this layer, publishing more pages rarely helps—and GEO cannot cite what bots cannot fetch cleanly.
Audit modules
Crawl & index
robots, sitemaps, parameter handling, duplicate clusters, orphan URLs.
CWV & delivery
LCP candidates, image formats (WebP), JS/CSS weight, caching headers.
Architecture
Internal links, pagination, hreflang, staging hygiene.
Structured data
Validate Organization/Service/FAQ/Product types against visible content.
How it pairs with GEO
After technical blockers clear, we layer entity consistency and answer content via Generative Engine Optimization. Combined retainers follow the same honest SEO/GEO pricing posture (VI reference ~8–15M VND/month after audit).
- Week 1Read-only audit + prioritized backlog.
- Weeks 2–4Critical fixes with before/after evidence.
- MonthlyMonitoring, regressions, and release hygiene.

FAQ
Do you only advise?
We implement when given access—or pair with your engineers via clear tickets.
Is this separate from GEO?
Technical SEO is the substrate. GEO builds entity/answer layers on top. Many clients buy both.
Reporting?
Work log + GSC (when granted) + CWV field/lab notes. No fake rank screenshots.

JavaScript and modern frameworks
Client-rendered apps can rank, but only with deliberate rendering strategy, clean internal links, and status codes that reflect reality. We inspect what crawlers receive—not only what users see after hydration.
For marketing sites, we often prefer static or server-rendered HTML for critical landing templates, keeping interactivity progressive. For apps, we isolate indexable content from authenticated views.
Release hygiene
Staging domains must stay noindex. Preview deployments should not leak into sitemaps. Redirect maps accompany URL changes. We treat SEO as part of CI awareness: broken canonicals after a redesign are preventable.
Evidence-based prioritization
Not every warning in an audit tool is equal. We prioritize issues that block discovery or conversions, then schedule polish. Clients receive a backlog with severity, effort, and owner—engineering or content—so work does not die in a PDF.
When GEO is in scope, technical SEO tickets land first; entity and FAQ work follows. That sequence avoids decorating a site bots cannot reliably fetch.
Working with in-house SEO or agencies
We can be the technical implementer behind your SEO strategist. Tickets arrive with expected outcome and verification steps; we return proof (headers, screenshots, GSC annotations). That division of labor keeps strategy and engineering honest.
If you have no SEO owner, we can combine technical work with lighter content guidance—but we will not pretend a technical sprint alone creates topical authority in competitive tech categories.
International technical considerations
Hreflang mistakes create the wrong regional page in SERPs. CDN misconfiguration can geo-serve stale HTML. We verify what Googlebot and users receive from major regions when international SEO is in scope. Combined with GEO, we also check that public entity facts do not diverge across language domains.
Migrations deserve redirect inventories before DNS cutover. We have seen brands lose years of equity to blanket 302s and homepage funnels—avoidable with disciplined maps.
Tooling stance
We use standard crawlers and Search Console—not proprietary mystery scores. When we recommend a tool, it is optional. The deliverable is a healthier site, not a dashboard subscription.
