Technical SEO consultant with ten years in search

Technical SEO is the work of making sure Google and AI assistants can find, read and list every page that matters on your site. It's for businesses whose pages are good and still don't rank. I'm Will Sibley, a technical SEO consultant working alone, and I do the fixes myself, from £1,000 a month ($1,500).

Send me your site

I reply myself, usually within one working day.

Proof

Technical SEO results from sites I've worked on

Both numbers come from work I did myself. At The Telegraph I worked across the newsroom on one of the UK's largest sites. On the Shopify store, Google was showing a vendor page and a tracking copy of a product address in place of the real pages, so I fixed that first.

What's included

What technical SEO covers, in plain English

Technical SEO is everything that helps search engines find, read and trust your site. On an established site it's often the cheapest ranking gain going, because the fixes let pages you've already paid for reach Google. It's one part of my wider SEO services, and it covers these seven areas.
  1. 01

    Crawling

    Crawling is Google's software following links to find your pages. I check your internal links, your XML sitemap, which is the list of pages you hand to Google, and robots.txt, the file that tells crawlers where not to go. Google says crawl limits start to matter at around 10,000 pages that change daily.

  2. 02

    Rendering and JavaScript

    Rendering is turning a page's code into what a visitor sees. Some sites send a near-empty page that fills in once JavaScript runs in the browser. Google usually copes with that. The crawlers behind ChatGPT, Claude and Perplexity don't run JavaScript at all, which matters for AI search.

  3. 03

    Indexing and duplicate pages

    Google's index is its list of pages it can show in results. I use canonical tags, the lines that tell Google which address is the real one, and noindex tags, which keep a page out of the results. Each page ends up with one address, and filter pages and tracking copies stay out.

  4. 04

    Site structure and internal links

    Every page that earns money should sit within about three clicks of the homepage. I crawl the site with Screaming Frog and sort the pages by how many internal links each gets. On the sites I audit, that list rarely matches the pages that earn the most.

  5. 05

    Speed and Core Web Vitals

    Core Web Vitals are Google's three measurements of how a page feels to real visitors. The main content should appear within 2.5 seconds, a tap should get a response within 200 milliseconds and the layout shouldn't jump about. I work from real visitor data in Search Console, slowest templates first.

  6. 06

    Structured data

    Structured data, also called schema markup, is a set of hidden labels that tell machines what a page is, such as a product, a review or a business. It's what puts prices and star ratings under a Google listing. I add each type once and check it with Google's Rich Results Test.

  7. 07

    Redirects and site hygiene

    A redirect is the rule that sends an old address to its new one. I check that each one arrives in a single step and that no internal link points at a missing page. If a rebuild is coming, see site migrations.

How it runs

How technical SEO runs, from first look to monthly checks

  1. 01

    Day 1

    A first look

    Send me your address. I check which pages Google has listed, how the site loads on a phone and whether your content shows up with JavaScript switched off. Then I reply with what I found.

  2. 02

    Weeks 1 to 3

    An audit, or a review of yours

    A full SEO audit takes two to three weeks from access to the finished list, with every fix ranked by traffic gained against effort. If you already have an audit from someone else, I'll work from it and tell you what it missed.

  3. 03

    Month 2 onwards

    The fixes

    I make the changes myself where I have access to the site or its code. Where your developers own it, I write specifications they can build from. Fixes on an established site often show in Search Console within a few weeks.

  4. 04

    Every month

    Checks after each release

    I review new releases and read Search Console's indexing report, so fixed faults stay fixed. You get one page on what changed, what I did and what comes next.

Price

What a technical SEO consultant costs

Monthly technical SEO starts at £1,000 a month ($1,500). Audits and migrations are quoted on scope, because a forty-page brochure site and a store with 4,000 products need very different amounts of work. I send a fixed price before anything starts.

How to choose

Should you hire a technical SEO agency or a consultant?

Hire an agency if the work needs several people at once, and a consultant if you want one senior person to find the faults and fix them. Sibley Digital is one consultant, me, so this table sets out when each is the better fit.
An agency is the better choice whenOne consultant is the better choice when
You need developers supplied as part of the same contract.You want the person who audits the site to be the person who fixes it.
You want paid search, content and technical SEO from one supplier.You already have developers and need specifications they can build from.
You run several large sites that each need someone on call every day.You have an audit from someone else and want a second opinion on it.
Your buying process requires a supplier with a team behind it.The site has a set list of faults, which makes it a project with an end date.

Whoever you choose, ask to see a sample audit. Check whether its fixes are ranked by traffic gained or listed in the order the crawler found them. If you run an agency, I do this work under your brand through my white-label service.

Questions

Technical SEO questions

What is technical SEO?

Technical SEO is the work that helps search engines find, read and trust a website. It covers crawling, indexing, site structure, speed and structured data. A fix to one page template improves every page built on it, which no single article can do.

What does a technical SEO consultant do?

A technical SEO consultant finds what stops search engines reading a site, then fixes it or writes the fix up for developers. I crawl the site with Screaming Frog, read your Search Console data and rank every fault by the traffic it costs you.

How much does a technical SEO consultant cost?

Monthly technical SEO with me starts at £1,000 a month ($1,500). Audits and migrations are quoted on scope, and I send a fixed price before any work starts.

What's the difference between technical SEO and on-page SEO?

Technical SEO deals with the whole site, meaning whether its pages can be crawled, listed and served fast. On-page SEO matches each page to a search through its title, headings and text. You need both, and I cover the second under content and on-page SEO.

Is technical SEO a one-off fix or ongoing work?

Mostly a one-off. A site has a fixed number of real faults, and once they're fixed they tend to stay fixed. After that it's a smaller monthly job of checking releases, plus a full review once a year and around any redesign.

How do I know if my site has technical SEO problems?

Three free checks will tell you. Search Google for site:yourdomain.com and compare the count with the pages you really have, then read why pages are left out in Search Console's indexing report. Last, run a key page through PageSpeed Insights.

Which platforms do you work on?

WordPress, Shopify, Webflow and custom builds on frameworks such as Next.js. The checks are the same on each, and the fixes live in different places. See WordPress SEO and Shopify SEO for the detail.
