Technical SEO is three questions a machine asks about your website. Can I reach this page. Can I understand it. Is it the right one to show. Everything filed under the term is one of those three questions wearing specialist vocabulary.
Nearly everything written on this subject is aimed at people who do it for a living. That is reasonable, and it leaves business owners buying something they cannot evaluate. This piece is the owner's version: what the words mean, what breaks in practice, how to tell whether yours is broken without buying a tool, and what it is fair to pay.
- Technical SEO answers three questions: can a machine reach the page, understand it, and tell it is the right one. Every term in the field belongs to one of those three.
- The failures that matter most are total rather than partial. A page blocked from crawling does not rank badly, it is absent.
- Four checks, fifteen minutes, no tools: a site: search, reading your own robots.txt, loading the site on mobile data, and searching your own headline in quotation marks.
- Technical work makes a page reachable, readable and unambiguous. It does not make the page worth reading, and a flawless site saying nothing anyone searches for ranks for nothing.
- It is mostly a one-off correction plus light maintenance. An ongoing monthly technical retainer on a site that rarely changes is monitoring, which is fine if it is described as monitoring.
The three questions
Can I reach this page? A search engine finds pages by following links and reading a list you provide. If a page is linked from nowhere, blocked by a rule in a file most owners have never opened, or sitting behind a login, it might as well not exist. This is the category where the failures are total rather than partial: the page does not rank badly, it is absent.
Can I understand it? Once reached, the page has to be readable. That means the text is genuinely in the page rather than assembled afterwards by scripts that a machine may not run. It means headings that describe sections, images that carry a description, and a page that loads before anyone gives up.
Is it the right one? If four addresses show the same content, which is the real one? If you have a page for Manchester and one for Leeds and they are ninety per cent identical, which answers a search for either? Ambiguity here does not produce an error message. It produces a quiet decision made without you.
The vocabulary, translated
The terms you will see on a proposal, in plain words, with what actually goes wrong.
What actually breaks on small business websites
Audit reports run to eighty items. In practice a small number of failures account for most of the damage, and they are unglamorous.
- A blocking rule left in place from the build. The site was hidden while it was being made and nobody removed the instruction afterwards. Total invisibility, trivial fix, and it can sit undiscovered for a year.
- A redesign with no redirect map. Every old address returns an error. Whatever the previous site had earned is discarded, and the drop arrives a few weeks later when everyone has stopped watching.
- Four versions of the same homepage at four addresses, none of them nominated as the real one.
- Images straight from a camera. A single unresized photograph can outweigh the rest of the page combined. The most common cause of a slow small business site by a wide margin.
- A page for every service and town, all near-identical. Thin pages built to catch searches, competing with each other and diluting the site.
- Nothing in the code saying what the business is. No structured data, so both Google and the AI assistants are inferring from prose rather than reading a statement.
Checking yours without buying anything
Four checks, about fifteen minutes, no tools beyond a browser.
- Search for
site:yourdomain.comin Google. The rough number of results is how many of your pages are stored. If it is far below your real page count, you have a reach problem. If it is far above, you probably have duplicates or thin generated pages. - Visit
yourdomain.com/robots.txt. If you seeDisallow: /on its own, your site is asking not to be listed at all. That single line is the highest-stakes character string on most websites. - Open your site on a phone, on mobile data, not office wifi. Count the seconds before you can read something. Over four and you are losing people before the content is even a factor.
- Type your best page's exact headline into Google in quotation marks. If your own page does not come back, it is not stored, and no amount of content work will help until that is fixed.
These are blunt instruments. They will not find a subtle canonical problem. They will find the failures that matter most, which are the total ones.
What technical SEO is not
It is not content, and it is not keywords. Technical work makes a page reachable, readable and unambiguous. It does not make the page worth reading. A technically flawless site saying nothing anybody searches for will rank for nothing, and that is not a technical failure.
It is also not permanent, but it is close. Most of it is a one-off correction plus light maintenance. Anyone selling you an ongoing monthly technical retainer for a site that does not change much is selling you monitoring, which is fine as long as it is described as monitoring.
One note on AI assistants, because the question always comes: the same work that lets a search engine read your pages is what lets an assistant read them too. Whether they can find and describe your business is a separate subject, and we cover it on the AI visibility page rather than here.
The three-question framing, the grouping of terms under it, and the list of what most commonly breaks on small business sites are our editorial account drawn from client audits, not a ranked measurement or a published Google framework. The four self-checks are deliberately blunt and will not surface subtle canonical or hreflang problems. The $500 technical SEO foundation line, the $4,900 build total and the $1,350 a month SEO and AI search rate are our published prices, listed in full on the pricing page. The 47% organic traffic figure over 90 days is from our own client engagement and its measurement method is on the case study page.
What it should cost
On a new build with us it is a line called technical SEO foundation, $500, inside the $4,900 total, and it covers schema, speed, sitemaps and llms.txt from day one. Every line is itemised on the pricing page.
On an existing site it is a fix rather than a subscription. Ongoing SEO and AI search work starts at $1,350 a month, and technical maintenance is a small part of that; most of the money goes to content and the things that actually move rankings once the plumbing works.
For a UK fashion house we rebuilt the site in thirty days and cleared its technical SEO debt before touching content at all. Organic traffic rose 47% in 90 days while their paid spend came down. The case study sets out what was broken and how the number was measured. The sequence matters there: the technical work did not create the traffic, it removed the reason the existing pages could not earn any.
If you are holding a proposal full of the words in the table above, ask which of the three questions each line answers, and what specifically is broken on your site right now. A good answer is short and names actual pages. A vague one means the audit was generic.
