If you own a business but your agency or developer owns the website, a technical SEO checklist written for practitioners is no use to you. You cannot open Search Console. You cannot edit a file. This checklist is built differently. Every check below runs from the outside, with no logins, in about twenty minutes. You will finish knowing whether your site is technically broken, and you will have the exact words to send to whoever can fix it. That second part matters more, because a problem you can name is a problem someone can be held to.
Key Takeaways
- Most technical SEO problems are invisible to the business owner. Your website can look perfect in your browser and still be unreadable to Google.
- You do not need site access to diagnose the problem. Your robots.txt, your sitemap and your page source are all public files. So is your speed score.
- Not showing up is not always technical. It can be technical, it can be content, or the site can simply be too new. Working out which comes first.
- AI search has raised the stakes. Most AI crawlers do not run JavaScript, so a site Google can just about read may be invisible to ChatGPT and Perplexity.
- The most valuable output of this checklist is a request, not a fix. Knowing what to ask your developer for is what actually gets things changed.
This checklist comes from someone who found technical SEO intimidating too
I have a non-tech background. For a long time, technical SEO felt like something other people were qualified to do. I would open a guide, hit the word “canonical” somewhere in the third paragraph, and quietly close the tab. If that is roughly where you are with your own website, you are in the right place, because I remember that feeling clearly.
Then I found Screaming Frog tool, and it changed how I work. Now when I audit a website I feel a bit like a doctor. Symptoms first, then the diagnosis, then the fix. (Given the tool is named after a frog, and most of us met our first one on a dissection tray, the medical comparison rather writes itself.)
The certificate is not a mastery badge, and I am still learning. What the training changed was not my ability to run a crawl, because anyone can press the button. It was learning which findings actually matter and which ones you can safely ignore. That is the whole difference between an audit that moves your traffic and a PDF full of red boxes.
So the checklist below is written the way I wish someone had written it for me. No assumed knowledge, no logins required, and every technical term explained the moment it appears.
Is your website technically broken, short on content, or just too new? How business owners can tell before spending a penny
If your site does not appear in Google at all, that is usually technical. If it appears when you search your business name but nowhere else, that is usually content or authority. If the site is under six months old and you have published very little, it may simply be too early. Work out which of the three you have before you pay to fix any of them.
This is the step almost everyone skips, and it is why so many business owners spend money on the wrong thing.
Type site:yourdomain.co.uk into Google. If nothing comes back, or only your homepage comes back, you have a technical problem and this checklist is exactly what you need. If dozens of your pages come back but none of them rank for anything a customer would search, your technical foundation is probably fine. Your problem sits in your on-page SEO or in the authority you have built off your site instead.
In short: technical SEO decides whether Google can find and read your pages. Content and authority decide whether Google chooses to show them. Fixing the wrong one costs you months.
The technical SEO checklist business owners can run without a single login
Every check here works from outside the site. You need a browser and nothing else. Run them in order, note what looks wrong, and take the whole list to your developer at the end rather than sending eight separate emails. Twenty minutes now saves a quarter of guessing.
1. Check Google has indexed your pages, so customers can find more than your homepage
Search site:yourdomain.co.uk. Google shows you roughly which of your pages it has stored. Count them against the pages you know exist. A ten page site returning two results has a problem. A site returning nothing has a serious one.
2. Read your robots.txt to see whether your site is accidentally blocking Google
Go to yourdomain.co.uk/robots.txt. This public file tells crawlers where they may go. You are looking for Disallow: / sitting under User-agent: *. On its own, that line blocks your entire site from everything. It is rare, it is catastrophic, and it usually happens when a staging site goes live without the setting being changed.
3. Check your sitemap includes the service pages that actually make you money
Try yourdomain.co.uk/sitemap.xml or /sitemap_index.xml. This is the list of pages your site hands to search engines. Scan it for the pages that bring in enquiries. If your main service page is missing, Google is being told it does not matter. Worth knowing: submitting a sitemap gets you discovered, not indexed.
4. Test your mobile load speed, because that is where your customers actually arrive
Put your homepage into Google PageSpeed Insights and read the mobile score, not the desktop one. Do not fixate on the number. What matters is the diagnostics underneath it, which name the specific files slowing you down. Those are what your developer needs to see.
5. Check your content is readable without JavaScript, or AI tools will see an empty page
Right click your homepage and choose View Page Source. Use Ctrl+F to search for a sentence you know is on the page. If you find it, your content sits in the raw HTML and every crawler can read it. If you cannot find it, your content is being built by JavaScript after the page loads. Google usually copes. Most AI crawlers do not.
6. Check your site loads at one address, not four competing versions
Type your domain four ways: with and without www, and with http and https. All four should land at the same address. If they load separately, search engines may treat them as different sites competing against each other.
7. Check every key page has one clear H1, so Google knows what you sell
On a key page, use View Page Source and search for <h1. You want one per page, describing what the page offers in the words a customer would use. Pages with no H1, or six of them because of a page builder, give Google nothing to work with.
8. Check you have structured data, so search engines describe your business accurately
Run your homepage and one service page through Google’s Rich Results Test. Structured data is code that tells search engines what kind of business you are and what you offer. Without it you rely on Google guessing. With it, you become far easier for both Google and AI assistants to describe correctly.
What a full technical SEO audit finds that these eight checks cannot
The eight checks above catch the problems that stop your site being found at all. A full audit catches the slower leaks: broken links, redirect chains, duplicate page titles, pages nothing links to, and thin pages competing against your own service pages. These rarely make a site invisible. They quietly hold it back for years.
A crawler visits every page on your site the way a search engine would, then reports what it found. I use Screaming Frog for this. It produces a list of everything wrong with a website, which is a humbling document no matter whose site it belongs to.
The skill is not running the crawl. Any tool can produce four hundred flagged issues. The skill is knowing which twelve of them are costing you enquiries, and which of the rest are noise. That judgement is the part you are paying for, and it is why a full audit sits at the front of my SEO services rather than being sold as an add-on.
None of this is theoretical. Working with a healthcare brand, I ran the technical side alongside on-page and off-page work, and domain authority moved from 15 to 28 in six months. The technical fixes were not the glamorous part of that project. They were the part that made everything else work.
How business owners can check whether ChatGPT and Perplexity can read their website
Search engines and AI assistants read your site differently. Google renders JavaScript, with a delay. Most AI crawlers do not render it at all. That means a site Google can just about understand may be entirely invisible to the tools your customers increasingly ask for recommendations.
This is why check 5 matters more than it used to. If your content only appears once JavaScript has run, ChatGPT sees an empty page where your services should be.
Two things to look at. First, that page source test. Second, your robots.txt again, this time looking for lines naming GPTBot, PerplexityBot, ClaudeBot or Google-Extended. If any of those are disallowed, somebody has decided your business should not appear in AI answers. Sometimes that was deliberate. More often a plugin or a host made the decision for you and nobody mentioned it.
Once the technical door is open, the next question is what makes an AI tool choose your business over a competitor. I went through that process on my own site and wrote up the workflow I used to get cited by ChatGPT.
In short: if your content is not in the raw HTML and your robots.txt blocks AI crawlers, no amount of content strategy will get your business mentioned in an AI answer.
What to send your developer: the exact words that get each technical SEO fix done
The gap between finding a problem and getting it fixed is usually wording. A vague request gets deprioritised. A specific one gets done. Here is what to send for each check, written so you can paste it into an email without having to defend it technically.
| What you found | What to send |
Missing pages in your site: search | “Several of our pages are not appearing in Google. Can you check the indexing report in Search Console and tell me which pages are excluded and why?” |
Disallow: / in robots.txt | “Our robots.txt appears to block all crawlers. Can you confirm whether that is intentional and, if not, correct it today?” |
| Service pages missing from your sitemap | Our sitemap does not include X page. Can you make sure every published service page is in it?” |
| A poor mobile speed score | “PageSpeed Insights flags [issue] on mobile. Can you look at the diagnostics and tell me what is realistic to fix and what it would take?” |
| Content missing from page source | “Our page content does not appear in the raw HTML. AI crawlers cannot read JavaScript-rendered content. Can we server-render the main content on key pages?” |
| Multiple versions of the domain loading | “Our site loads on both www and non-www. Can you set up redirects so everything resolves to one version?” |
| Missing or duplicate H1s | “This page has no clear H1 heading. Can we set one that describes the page in plain language?” |
| No structured data | “We have no structured data. Can we add Organization and Service schema so search engines and AI tools understand what we do?” |
One more request, and it is the most important one on this page. Ask to be added as an owner on Google Search Console and Google Analytics. If somebody else holds sole access to data about your own business, that is worth a conversation. Not because they are doing anything wrong, but because you should be able to see it.
Technical SEO mistakes business owners make when they assume the plugin has it covered
The expensive mistakes here are not things business owners do. They are things they assume have already been done. Five come up again and again, and every one of them costs months.
- “We have Yoast installed, so technical SEO is handled.” An SEO plugin generates a sitemap and gives you fields for titles. It does not audit anything, and it will happily let you publish a page marked noindex.
- “A redesign will fix our rankings.” Redesigns break more SEO than they fix. URLs change, redirects get missed, and traffic that took two years to build disappears over a weekend.
- “We submitted the sitemap, so we are indexed.” Submitting means discovered. Google can hold a page and still decide not to show it.
- “Posting more on social will lift our rankings.” Google has been clear that likes and follower counts are not ranking factors. Shares can indirectly earn links, and links do count, but that is a longer road than most people expect.
- “SEO takes time, so there is nothing to worry about yet.” It does take time. It is also the most common cover for nothing happening. Three to six months is fair for seeing movement. Three to six months with no report, no list of completed work and no access to your own data is a different situation entirely.
Technical SEO Frequently Asked Questions from business owners
As a business owner, my website only shows up when I search my business name. Is that a technical SEO problem?
Usually not. If Google finds you for your business name, it has indexed you, which means the technical door is open. That pattern normally means you have no pages targeting what customers actually search for, or you have them and other sites carry more authority. Run the site: check to confirm your pages are indexed. If they are, your next investment is content and links rather than technical work.
My website looks completely fine to me, so how can it have technical SEO problems?
Because you are not seeing what a crawler sees. You are looking at a rendered page in a browser, often cached, often while logged in. A search engine reads raw code, follows instructions in files you have never opened, and gives up after a certain amount of effort. A site can look immaculate and still be telling crawlers to stay out.
As a business owner with no website logins, which technical SEO checks can I still run myself?
All eight in this article. Your robots.txt, sitemap and page source are public files anyone can view. PageSpeed Insights, the Rich Results Test and a site: search need no access at all. What you cannot do without logins is see Search Console data, and you cannot make changes. That is exactly why the wording section above exists.
Should my SEO agency have given me access to Google Search Console?
You should be an owner on both Search Console and Analytics for your own domain. Plenty of good agencies set these up under their own account without thinking about it, so ask before assuming anything. The answer tells you a lot either way. An agency that adds you within the day is one thing. An agency that explains why you do not need it is another.
How does a business owner check whether ChatGPT and Perplexity can read their website?
Two checks. View your page source and search for a sentence from the page. If it is not there, AI crawlers probably cannot read your content. Then open your robots.txt and look for GPTBot, PerplexityBot or ClaudeBot being disallowed. You can also simply ask ChatGPT to summarise your homepage. If it cannot, or it invents something, that is your answer.
As a business owner, how long after technical SEO fixes should I expect more enquiries?
Indexing fixes can show within days, because you are removing a blocker rather than building something new. Speed and structure improvements take longer, generally three to six months before they show up as enquiries rather than impressions. Be careful of anyone promising faster, and equally careful of anyone who cannot show you what they have actually changed.
Your website should not be a black box you pay for
You should not have to become technical to know whether the thing you are paying for is working. That is the honest version of this problem, and it is why I wrote the checklist this way round.
Run the eight checks. Send the requests. If something comes back that you do not understand, or the answers you get do not sound right, book a free technical SEO audit and I will crawl your site and tell you the three things costing you the most visibility, in plain English. No obligation, and no report full of red boxes designed to frighten you into a retainer.
