Technical SEO · Developer-led

Technical SEO by the developer who writes the code

Technical SEO is everything that decides whether a page can be crawled, rendered, indexed, understood and served fast: Core Web Vitals, server-side rendering, structured data, canonical and redirect logic, sitemaps, robots and AI-crawler access, internal linking and migrations. Velour Web does it as the developer, not as an agency writing tickets for someone else's developer: we fix the build. Audits with a prioritized fix list from $1,500; fixes on an existing fast site $1,500 to $6,000; rebuilds on Next.js that keep every URL and ranking $8,000 to $25,000. Our 76-site San Diego audit found 42% of local sites load 20 or more scripts and 29% respond in over a second; that is the work.

What technical SEO covers in 2026

Nine areas, in the order they usually fail on a local business site.

Speed and Core Web Vitals: script count, render-blocking resources, image sizing and format, font loading, server response. Target: under one second on a phone, PageSpeed 90 or higher.
Rendering: content present in the HTML the server sends, so Google, Bing and live-reading AI engines read it without running JavaScript.
Structured data: LocalBusiness or subtype with sameAs, Service, FAQPage, Article, Offer, BreadcrumbList and Speakable, generated from the page's own data so it never disagrees with the visible text.
Crawl and index control: one canonical per page, redirects that resolve in one hop, no soft 404s, sitemaps with real last-modified dates submitted to Google and Bing, indexing requested for new pages.
AI crawler access: GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended and Bingbot allowed; llms.txt published.
Site architecture and internal linking: a page per service and city, linked so the site reads as one connected business, with no orphan pages.
On-page basics still broken on a third of local sites: one H1, titles under 60 characters, meta descriptions, alt text, heading order.
Migrations: moving off WordPress, Wix or Squarespace, or between domains, with a URL map, redirects and a rankings watch, so nothing is lost.
Monitoring: Search Console, Bing Webmaster Tools, uptime, Core Web Vitals field data, and a monthly check.

Why the developer should do it

Most technical SEO reports end with a list of recommendations for a developer who was not in the room. Half of them never ship. We are the developer. A finding about render-blocking scripts becomes a change to the build, not a ticket. A schema recommendation becomes a generator that puts the right markup on every page from the data it is built from. On a hand-coded Next.js site this is straightforward; on a plugin-driven site the honest technical audit often ends with 'the build is the problem', and we say so and quote the rebuild that keeps the URLs.

The audit

From $1,500 for a site of up to 100 pages: a crawl, lab and field speed data, rendering checks, structured data validation across every template, index coverage from Search Console, redirect and canonical review, AI-crawler access, internal-link map, and a fix list in order of impact with what each fix takes. Delivered in five business days with a walkthrough call. Credited toward the fixes or the rebuild.

Next.js, headless and static builds

Our own stack: Next.js, TypeScript, static generation, deployed to a global edge network, with every page generated from typed data files. It is why this site ships 170 URLs at 99 to 100 on Lighthouse with a handful of scripts. We build client sites the same way, migrate WordPress and builder sites onto it, and consult for teams already on Next.js or a headless CMS who need rendering, schema or crawl problems fixed by someone who has shipped them.

Where we work

Technical SEO is remote-friendly; we do it for businesses anywhere and meet in person in San Diego County and Los Angeles. Fixed quotes after the audit, no retainers required.

FAQ

Common questions

What is technical SEO?

The work that decides whether a page can be crawled, rendered, indexed, understood and served fast: speed and Core Web Vitals, server rendering, structured data, canonicals and redirects, sitemaps, robots and AI-crawler access, architecture and migrations.

How much does a technical SEO audit cost?

From $1,500 for a site of up to 100 pages, delivered in five business days with a prioritized fix list, credited toward the fixes or a rebuild.

Can you fix Core Web Vitals on a WordPress site?

Often partially: images, fonts, caching and removing plugins. When the theme and page builder are the weight, which is common at 20 or more scripts, the honest answer is a rebuild that keeps the URLs, and we say so.

Do you do site migrations?

Yes. A URL map, one-hop redirects, schema and content parity, sitemaps resubmitted, and a rankings watch for 90 days. Moving off WordPress, Wix, Squarespace or between domains.

Do you work with Next.js?

It is our stack. We build on it, migrate to it, and consult for teams already on it or on a headless CMS.
