The Complete SEO Checklist 2026 (Updated for AI Search)

TL;DR

• SEO puts your business in front of people who are already searching for what you do, and most of it is set up once and then maintained in about twenty minutes a month.
• The order matters: the basics first, then your Google Business Profile, then pages Google can read, then content that answers real questions, and then AI search.
• AI search needs nothing extra. Google has said so, and the pages that rank well in Google are the same pages that AI answers quote.
• Write down three numbers from Search Console before you start, because they are the only way to tell what worked.

What does SEO actually do for a small business?

SEO gets your website shown to people who are already looking for what you sell. Google decides which sites to show by how easy they are to find, understand and trust, and every item on this list improves one of those three things. When we rewrote the service pages and page titles for a Gold Coast smart home installer, visits from Google rose 175 per cent, and none of that work cost anything beyond the time to do it. That is the benefit for a small business: SEO costs time rather than money, and it keeps paying off after the work is done. If you would rather have it handled, that is what our search service does. If you want to do it yourself, this page is the order I would do it in.

Why write down three numbers before you start?

Because without a starting point you will never know whether any of this worked. Google Search Console reports how often your site appeared in results, how often someone clicked, and the exact words they typed. Open it now and write down your clicks, your impressions and your top five queries for the last three months. If you have never set it up, that is the first item in Part 1. Every step below is measured against those three numbers, so in three months you will be able to say exactly what changed.

Part 1: The basics

These are the things you do once, and in most of the sites I audit at least two of them are missing.

1. Turn on HTTPS on your own domain. Look for the padlock in the browser bar, and if it is missing, switch HTTPS on in your platform's settings. Browsers label a site without it as not secure and Google treats it as a ranking signal, so turning it on removes a warning every visitor would otherwise see.
2. Give the site a title that says what you do. Write your business name, your trade and your area into the site title, in the form "Smith Plumbing | Hot Water and Blocked Drains, Gold Coast". Google reads the site title before anything else on the page, and a trade plus an area is exactly what a local search is matching against.
3. Write a unique title and description for every page. Keep each title under 60 characters with the main topic first, and each description under 160 characters. The title is the blue link in the results and the description is the text under it, so between them they decide whether a person clicks on you or on the listing below.
4. Connect Google Search Console. Add your site as a domain property and verify it with a DNS record. Search Console is free, it shows you the queries people typed before they found you, and it tells you when something breaks. Verifying by DNS means the connection survives a change of platform.
5. Connect Google Analytics. Add the tracking code or tag to your site and confirm it is recording visits. Search Console shows how people arrive and Analytics shows what they do next, so between them you can see which pages turn a visitor into an enquiry.
6. Submit your sitemap in Search Console. Paste your sitemap address, which on every modern platform is /sitemap.xml, into the Sitemaps section. That tells Google every page you want indexed instead of leaving it to find them on its own.
7. Set up a custom 404 page. Build an error page that links to your services, your contact page and your home page. Links break over time, and a page with your services on it keeps the visitor that a plain error page loses.
8. Add a favicon and a social sharing image. Upload your logo as the favicon and a photo of your work as the sharing image. They decide how your site looks in a browser tab and in a text message, and a blank grey square makes a business look abandoned.

Part 2: Get found locally

For a trades or service business, this part earns more than everything else on the page put together, because most of your customers are searching for a trade plus a suburb.

1. Claim your Google Business Profile and fill in every field. Complete the categories, services, hours, phone, website, description and photos, and leave nothing blank. Google has said that a complete profile is easier to match to searches, and a finished profile outranks a half-finished one for the same search.
2. Choose the right primary category. Pick the category that names your trade, so "Electrician" rather than "Contractor". Google matches the primary category directly against what people search for, which makes it the single biggest lever on the profile.
3. Add real photos. Take real photos of the van, the team and the finished job. Your own photos are far more convincing to a visitor than stock photos, because they show a real business they can picture turning up.
4. Ask for reviews and reply to every one. Ask each customer for a review at the end of the job, and reply to every review you get within a few days. Reviews are a ranking factor and a trust signal at the same time, a steady few a month does more than a burst of twenty, and a reply shows both Google and customers that someone is paying attention.
5. Use one version of your name, address and phone number everywhere. Write them the same way on your website, your profile, your Facebook page and every directory. Google cross-checks those sources against each other, and a mismatch costs you trust that a consistent listing earns.
6. Make a page for each service and a page for each area you work in. Give "Hot water repairs on the Gold Coast" its own page with its own title, rather than a line in a list on your services page. Google ranks pages rather than businesses, so a dedicated page is what competes for that search, and a line in a list cannot.

Part 3: Pages Google can read

Google can only rank what it can read, and these seven items are how you make a page readable.

1. Give each page one topic. Google ranks a page for the thing it is clearly about, so a page that tries to cover three things usually ranks for none of them.
2. Put the topic in the title, the main heading and the first sentence. Those are the three places Google weights most, and once they are done you can write the rest for the person reading.
3. Use plain URLs. An address like /services/hot-water-repairs tells Google and the reader what the page is before it loads, and /page-id-4471 tells them nothing.
4. Add alt text to every image and keep image files under about 500 KB. Alt text is how Google reads a picture, and oversized photos are the most common reason a small business site is slow.
5. Check your speed on a phone. Google publishes the targets it measures: the main image should load within 2.5 seconds, a tap should get a response within 200 milliseconds, and the page should not jump around while it loads. PageSpeed Insights tests your site against those numbers for free, and a site that passes them keeps the visitors that a slow site loses.
6. Link your pages to each other in the body text. Google follows links to understand which pages matter, and so do your visitors. A service page should link to its related article and the article should link back, so both get found.
7. Fix or redirect every broken link. Each old address should land on its new equivalent, because an old address that lands on your home page loses the ranking it had. This matters most after a change of platform, and we learned it the hard way on our own site this year.

Part 4: Content that keeps earning

The pages that keep earning are the ones that answer a real question, and these five habits produce them.

1. Write down the ten questions customers ask you every week. Each one is a page or an article, and together they are a year of content that you already know the answers to.
2. Answer the question in the first sentence, then explain. People skim, search engines skim, and the page that answers fastest is the one that gets read and quoted.
3. Add a short FAQ to every service page. Three to five real questions with direct answers give Google question-shaped content to match, and give the customer the answer before they have to ring.
4. Put your name on the work. Google's guidance on helpful content asks who wrote a page and why, and pages that make it clear do better. A byline and an author page cost nothing.
5. Update old pages instead of only adding new ones. A refreshed page with a real change in it beats a new page on the same topic, because it keeps the ranking history it already has. Changing the date without changing the content does nothing.

Part 5: Does AI search need anything different?

No. Google's own guidance says there are no additional requirements to appear in AI Overviews or AI Mode, no special files to add and no special markup. People now ask ChatGPT, Gemini and Google's AI Mode the questions they used to type into a search box, so this is the question I get asked most this year. AI answers are built from the same web pages Google already ranks, which means everything above still applies. What follows is what I have seen make the difference on our own site and on client sites.

1. Answer first and explain second. An AI answer lifts the sentence that answers the question, so if your first sentence is a warm-up, the answer gets lifted from someone else's page.
2. Write headings as the questions people ask. A heading like "How much does a new website cost?" can be matched to a question, whereas a heading like "Pricing" cannot.
3. Add FAQ sections with real answers and mark them up with FAQ structured data. The markup has to match the visible text, and a matched FAQ is the easiest content for an AI to quote.
4. Keep the facts about your business consistent everywhere. AI tools cross-check your name, address, phone, services and hours across sources, and if your website and your Google profile disagree you lose the citation.
5. Let AI crawlers in. Check that your robots.txt does not block GPTBot, ClaudeBot, PerplexityBot or Google-Extended, because a crawler that cannot read your site cannot quote it. Some platforms have a single setting that blocks all of them, so check yours.
6. Keep pages fast and server-rendered. If the text only appears after a script runs, some crawlers never see it.
7. Test it yourself. Log out, open AI Mode or ChatGPT, and ask the questions your customers ask, then note who gets cited. Do it again next month, and you have a measurement nobody else in your trade is taking.

Search Console counts visits from AI features inside your normal search traffic, so the three numbers you wrote down at the start still measure this part.

Part 6: What does it take to keep it going?

Twenty minutes a month. Most businesses that fall behind on SEO did not fail at anything difficult, they stopped doing the easy things, so once a month do the following.

• Open Search Console and compare clicks and impressions with last month, then look at the queries.
• Fix anything Search Console has flagged.
• Reply to every new review.
• Publish one new page or update one old one.

That is the whole job, and a business that does it every month will be ahead of most of its competitors within a year.

FAQs

How long does SEO take to work? Most small business sites see movement in Search Console within four to twelve weeks of fixing the basics. Competitive terms take longer, and local terms with a finished Google Business Profile often move fastest.

Do I need to pay for SEO tools? No. Google Search Console, Google Business Profile, Google Analytics and PageSpeed Insights are all free, and between them they cover everything on this list.

Is SEO still worth doing now that people use AI? Yes. AI answers are built from web pages, and they favour the same clear, trusted pages that Google does, so a site that ranks well is the site that AI quotes.

What should I do first? Set up Search Console and finish your Google Business Profile, because between them they cover most of what a local business gets from search.

Can you just do this for me? Yes. Start with a free website audit, and you will get a plain-English list of what is missing and what is worth fixing first.
