If Google can’t find your website, neither can anyone else. Sounds obvious. You’d be surprised how many businesses have a beautiful site that Google has barely heard of.
SEO (Search Engine Optimisation) exists to fix that. Its job is to get your website crawled, indexed and ranked so that people searching for what you offer can find you.
It’s the oldest layer of search, and every newer layer sits on top of it. Google’s own documentation on its AI features says the best practices for SEO remain relevant, that AI Overviews and AI Mode rely on its core ranking and quality systems, and that there are no additional requirements to appear in them. In other words, the fancy new stuff is built on the boring old stuff. Get the boring old stuff right.
The Three-Step Journey: Crawled, Indexed, Ranked
Every page on your site has to clear three hurdles, in order.
1. Crawled
Google sends automated bots to visit your site and follow your links. If they can’t reach a page (because it’s blocked, buried, or broken), it’s invisible before the race starts. Common culprits include pages blocked in robots.txt, orphan pages with no links pointing to them, and slow or unreliable hosting. Google’s guidance also reminds site owners to check that crawling isn’t being blocked by their CDN or hosting infrastructure, which catches out more sites than you’d think.
2. Indexed
Once crawled, Google decides whether the page is worth adding to its library. Thin pages, near-duplicate pages and pages that don’t offer anything new often get crawled but never indexed. Being indexed isn’t a given, it’s earned.
3. Ranked
Only indexed pages can rank. Ranking is where Google weighs hundreds of signals to decide who appears where for a given search. This is the step everyone obsesses over, but it only happens if the first two go well.
What SEO Actually Involves
It’s not one trick. It’s a handful of things done consistently.
Technical SEO
The behind-the-scenes plumbing that makes your site easy for Google to read: clean site structure, working links, sensible sitemaps, correct redirects, mobile-friendly design and secure hosting (HTTPS). Fixing technical problems doesn’t create demand, but it removes the roadblocks in front of it.
Core Web Vitals
Google’s measure of how fast and stable your pages feel to real visitors. There are three: Largest Contentful Paint (how quickly the main content loads, with 2.5 seconds or less considered good), Interaction to Next Paint (how quickly the page responds when someone taps or clicks, 200 milliseconds or less), and Cumulative Layout Shift (how much things jump around while loading, 0.1 or less). Google assesses these using data from real users, not just lab tests.
The business case is strong. In a controlled A/B test, Vodafone found that a 31% improvement in Largest Contentful Paint led to 8% more sales. And yet only about 48% of websites pass on mobile, so simply passing puts you ahead of roughly half the web.
High-quality content
Pages that genuinely answer what people are searching for. Not keyword-stuffed filler, and not a rehash of the same ten articles everyone else has published. Google’s guidance for AI features specifically warns against recycling what others have already said.
Topical authority
Google trusts sites that clearly know their stuff. That means covering a subject properly, with a main guide supported by related articles that dig into specifics and link to each other, rather than one lonely blog post. (This article is part of exactly that: a cluster on the five layers of search.)
E-E-A-T
Experience, Expertise, Authoritativeness and Trust. It’s Google’s framework for judging whether content comes from a credible source. In practice: real authors with real credentials, clear information about who you are, genuine reviews, and content that shows first-hand experience rather than generic advice.
Internal linking
Links between your own pages help visitors and Google find their way around, and they show which pages matter most. A page with no internal links pointing to it is like a shop with no door.
Schema markup
A layer of code that tells search engines exactly what your content is: a business, a service, a review, an article. It can make you eligible for rich results and helps machines understand your pages. One important update: Google retired FAQ rich results in May 2026, so don’t expect FAQ markup to earn you those dropdowns anymore. Schema is helpful, not magic.
Backlinks
Links from other reputable sites to yours. They’re still a meaningful signal of trust, but quality beats quantity every time. A handful of relevant, credible links is worth more than hundreds of junk ones.
SEO by the Numbers
- Google handled more than 5 trillion searches in 2024, and grew about 22% that year (SparkToro). Search is very much alive.
- Google held roughly 91% of global search market share in July 2026 (Statcounter, as reported by Ploy).
- 68.01% of US Google searches ended without a click in the first four months of 2026, up from 60.45% in 2024 (SparkToro).
- Around two-thirds of Google searches end without a click regardless of whether an AI summary appears, according to Pew’s study of 900 US adults.
- A 0.1-second improvement in mobile speed was associated with 8.4% higher retail conversions across 37 brands and over 30 million sessions (Deloitte and Google, 2020).
A quick note on a stat you’ll see everywhere: the claim that “organic search drives 53% of all website traffic.” It traces back to a BrightEdge study from 2019. It’s useful history, but it isn’t a universal 2026 benchmark, because the real figure depends heavily on your industry, brand awareness and how much you spend on other channels. Check your own analytics.
What’s Changed (and What Hasn’t)
The big shift is that ranking no longer guarantees a click. AI summaries, featured snippets and instant answers now absorb a lot of searches before anyone reaches a website. Pew found people clicked a traditional result in 8% of visits with an AI summary versus 15% without.
What hasn’t changed is the underlying logic. Google’s AI features draw from its search index. Pages that are crawlable, indexable, trustworthy and genuinely useful are the ones with a chance of being surfaced, whether as a blue link or a cited source. SEO isn’t being replaced. It’s being asked to do more.
Common SEO Mistakes
- Publishing without a plan. Random blog posts don’t build authority. A connected set of pages on your core topics does.
- Ignoring page speed. Especially on mobile, where most searches happen.
- Targeting keywords instead of questions. Match what people actually want to know, not just the phrase they typed.
- Set-and-forget. Google changes, competitors publish, and a neglected site slowly slides.
- Buying links. Cheap link packages are a fast route to a penalty, not a ranking.
- Chasing rankings over revenue. Traffic that doesn’t convert is a vanity metric (see SXO).
How You Know It’s Working
- Rankings: are you moving up for the searches that matter to your business?
- Organic traffic: are more of the right people arriving from search?
- Indexed pages: is Google actually seeing and storing your content? Google Search Console shows you this for free.
- Impressions and clicks: impressions rising while clicks stay flat can mean you’re being seen in answer features, not ignored.
- Enquiries and revenue: the number that matters most. Rankings are a means, not the goal.
Is SEO the Right Move for You?
It’s probably time, if…
- Your website isn’t showing up for searches you should own
- You’re paying for ads to cover a lack of organic visibility
- Your competitors keep outranking you with weaker offerings
- You want a channel that compounds rather than resets every month
It might not be, if…
- Your website is being rebuilt or is still a work in progress
- You need leads this week (paid search is faster, SEO is steadier)
- You want guaranteed rankings. No honest agency will promise them, and we won’t either
