Custom websites give you total control — over design, code, and performance. Our custom website SEO makes sure that control helps your rankings instead of hurting them: rendering Googlebot can read, clean URLs, and an architecture built to earn organic traffic.
What’s covered
A hand-built site has no plugin safety net. No SEO tool auto-generates your sitemap, no theme handles your canonical tags, no cache plugin papers over slow code — every technical detail is a decision someone made, and each one affects how Google crawls, renders, and ranks your pages. Custom website SEO is the discipline of getting those details right — here are the 8 technical angles we cover for custom-built and headless sites:
Many custom sites run on React, Vue, or Next.js, and client-side-only rendering can leave crawlers staring at an empty page. We check how your pages render for Googlebot, apply the right fix — server-side rendering, static generation, or prerendering — and verify noindex rules and sitemaps stay correct across builds.
Database-generated URLs often come out messy: IDs, query strings, inconsistent slugs. We design clean, keyword-friendly URL patterns for your data model, canonical rules so each page lives at one address — plus redirect logic in your routing layer, since custom routers ship with no redirect manager.
Custom code means full control over page speed — and full responsibility. We set Core Web Vitals budgets (LCP, INP, CLS), track down the scripts, fonts, and images eating into them, and keep every page fast on real mobile connections.
No plugin constraints means each page gets exactly the structured data it needs. We map schema types to your templates — Product, Article, FAQ, LocalBusiness, BreadcrumbList — and implement valid JSON-LD that qualifies your pages for rich results.
Headless setups — a CMS feeding a separate front-end via API — bring SEO pitfalls: preview URLs getting indexed, content not matching rendered HTML, sitemaps that don't know your real pages. Bespoke CMS dashboards with no SEO fields have the same problem. We lock down indexation for previews and staging, verify API content is crawlable, and build the front-end's sitemap and metadata layer.
Most custom-site SEO damage happens before launch: indexed staging sites, empty meta templates, key content lost in the redesign. We embed SEO in your workflow — noindex and auth on staging, launch checklists for metadata and redirects, and a pre-launch crawl.
Rebuilding or replatforming changes every URL — that's where rankings get lost. We map every old URL to its new counterpart, implement and test 301 redirects before launch, preserve titles and headings, and monitor indexation and traffic after the switch.
Custom sites let you design linking architecture from scratch — and many waste it on nav-only structures. We build hub pages, contextual links, and breadcrumb trails that push authority to priority pages and keep every key URL a few clicks away.
How we work
Custom builds need an SEO process that speaks your developers’ language:
We crawl your site the way Google sees it: rendered HTML, JavaScript dependencies, status codes, canonicals, indexation directives, mobile rendering. You get a findings report that separates real ranking blockers from cosmetic issues.
On custom builds, templates matter as much as individual pages. We review your page templates, metadata logic, URL routing, and sitemap generation to find the systemic issues repeating across every page.
Every finding is ranked by SEO impact and implementation effort, so your developers know what to fix first. Where you lack developer resources, our team can implement many fixes directly in your codebase or CMS.
We work alongside your developers: specs they can implement, pull-request reviews for SEO impact, and direct fixes where we have access. Nothing gets lost between the audit document and the deployed code.
After changes go live, we re-crawl to verify every fix, check Core Web Vitals on real devices, confirm schema validates, and monitor indexation and search performance. You get a completion summary with before-and-after evidence for each fix.
