CHARLIE X web systems / technical seo / bitcoin

Technical SEO and web infrastructure for Bitcoin companies.

I build and run the systems underneath websites that can't go down: hosting, DNS, SSL, deployment, and the technical SEO that decides whether anyone finds them. Ten-plus years in, the last few inside a top UK SEO practice working on crypto, payments and ecommerce. I also run a Bitcoin full node and publish House of Bitcoin, so I know the space from the inside.

Services

How we could work together.

Three ways in. The first is the easiest place to start.

Fixed scope

Technical SEO audit

Crawl and indexation, Core Web Vitals, schema, internal linking, plus DNS, SSL and email hygiene. You get a prioritised fix list, and I can implement it too.

Retainer

Web operations

Hosting, DNS, SSL, backups, deployments and monitoring, handled by one person who answers. For sites where downtime or an indexing failure costs real money.

Partnership

Data & editorial

Treasury and network data, co-authored research and features through House of Bitcoin. Editorial stays editorial. Anything sponsored is labelled as such.

Projects

Built and run by me.

Domains, DevOps, front ends, email and SMTP, newsletters, SSL and SEO, all done in-house. These are my own sites, so the results are public and you can check them.

Approach

Found. Believed. Fast.

Three jobs that people treat as separate and that are really one.

Search & discovery

Search Everywhere

Technical SEO, crawl and index architecture, backlink strategy, and analytics that show what actually drives growth in an AI world.

Trust & reliability

Building Trust

Clean DNS and SSL, solid email authentication, uptime and security. Content that stays accurate for a natually sceptical and hardened audience.

Performance

Ready to scale

Core Web Vitals, CDN and caching, and deployment pipelines that ship changes without breaking things.

2015 - 2020

Sectors

Where I operate.

The pattern across every long-term client: reliability and trust are the product, not the branding on top of it.

Crypto / blockchain

Bitcoin, Web3 & payment rails

Infrastructure and search-layer work for blockchain, token, and payment-gateway businesses - sectors where trust signals and technical correctness both matter.

Ecommerce

High-volume retail & DTC

Performance, technical SEO, and platform stability for established ecommerce brands operating at competitive scale.

Technical SEO and systems reliability for regulated, reputation-sensitive digital platforms.

Entertainment & events

Bookable experiences

Ecommerce and event-booking systems for entertainment, hospitality, and independent media communities.

Stack

What I run.

AI now writes most boilerplate HTML, CSS, and PHP competently - so that's not where I spend my time or where I differentiate. I specialise in strategy, systems integration, and the judgment calls AI can't make on its own: which platform actually fits a client's scale, how to architect for search, and how to wire automation and APIs into something that holds up in production.
