Off-the-shelf SEO plugins don't exist for custom-built platforms. Whether you run Odoo ERP, a headless React or Next.js storefront, or a proprietary CMS, our engineers work in the codebase: server-side rendering, database structure and custom schema. That is custom website SEO optimization that search engines can actually reach.
React, Next.js and other JavaScript-heavy frontends often render content only in the browser. Without server-side rendering fixes, whole pages can vanish from search.
Odoo instances and custom CMS builds often have unindexed loops and mismatched metadata across systems, the waste a technical SEO for custom websites audit is built to catch.
Multi-company pricing, SKU variants and B2B tiers can create duplicate content at the database level, a problem generic SEO for custom website services rarely diagnose.
As an engineering-first custom website SEO agency, we don't apply templates. We audit server delivery, streamline rendering and build custom crawl rules so search engines index your content accurately.
From deep Odoo ERP structures to headless JavaScript layouts: architectures built to be visible, fast and authoritative at scale.
Our technical team handles code-level optimization and high-intent keyword targeting together, not as separate jobs.
| Platform type | Technical SEO challenges | AdvertX engineering strategy |
|---|---|---|
| Odoo ERP systems | Messy QWeb layouts, parameter string loops and unoptimized backend tables. | Clean module overrides, structured XML template maps and automated sitemap updates. |
| Custom code & PWAs | Client-side execution blocks, hidden text and unrendered JavaScript frameworks. | Server-side rendering, lean API execution and clean semantic structure. |
| Proprietary CMS builds | Missing SEO fields, rigid metadata controls and untracked code frameworks. | Custom middleware extensions, schema scripting and direct server configuration. |
Most agencies stop at plugin settings. When your platform has no plugin ecosystem, because it's Odoo, a headless React build or a proprietary CMS, that approach doesn't work. Our custom website SEO process is built on engineering, not templates.
Our specialists work in raw code (Python, Node.js, PHP, XML) to build search features natively, without pre-built SEO apps.
Every engagement opens with an audit of your rendering, database indexing, schema and crawl paths, because each platform builds pages differently.
Complex multi-company setups with accurate hreflang, multi-currency rules and localized translation, without splitting your domain authority.
Indexing fixes run through version-controlled staging environments, so your live operational databases stay protected.
We don't quote a fixed price or timeline upfront; every project is scoped on a call. We don't promise fixed rankings or set timelines; no credible custom website SEO agency can. We commit to code-level engineering, transparent reporting and a process built around how your platform really works.

Custom website SEO needs code-level work: server-side rendering, database indexing and hand-built schema, because no plugin ecosystem exists to do it. Every fix is built into the platform's codebase.
Yes. Odoo ERP storefronts need dedicated ERP SEO: QWeb template cleanup, database parameter controls and automated sitemap updates, since Odoo builds pages differently from standard ecommerce platforms.
A custom SEO website package usually covers server-side rendering fixes for JavaScript frameworks, database-level duplicate content fixes, structured data and a technical crawl audit scoped to your tech stack.
Technical fixes like rendering and schema can be deployed within weeks. Ranking gains from custom website SEO usually build over three to six months as search engines re-crawl the corrected architecture. No agency can guarantee rankings.
Yes. Custom SEO websites for small law firms and other service businesses benefit from clean, purpose-built architecture without template bloat, usually with a smaller scope than an enterprise ERP project.
Custom builds usually cost more upfront than template platforms. But the SEO advantages of custom websites, like precise schema control and faster pages, can reduce long-term reliance on paid ads.
We structure product, service and page data with verified entity markup and clean, citation-ready content, which generative engines use for AI Overviews and other AI answers, alongside traditional technical SEO.
