How Does SEO Work? A Beginner’s Guide to Search Engine Optimisation
I’ve been working in SEO since 2008, and if there’s one thing I’ve learnt, it’s that there isn’t one magic trick that gets your website to the top of Google. Search engine optimisation is made up of lots of different elements working together, and it takes time, experience and ongoing effort to get the best results.
One of the biggest misconceptions about SEO is that it’s all about rankings. Whilst rankings are important, they’re only valuable if they help the right people find your business. I’d much rather help a client rank for keywords that generate enquiries than chase high positions for search terms that never convert.
So, how does SEO work?
In simple terms, SEO is about helping search engines understand your website whilst creating the best possible experience for your visitors. The better Google understands your website and the more useful it believes your content is, the more likely it is to recommend your pages in the search results.
Let’s look at how the process works.
What Is SEO?
SEO stands for Search Engine Optimisation. It is the process of improving your website so that it appears higher in the organic (non-paid) search results when people search for products, services or information related to your business.
Unlike paid advertising, you don’t pay every time someone clicks on your website. Instead, you earn those positions by demonstrating to Google that your pages deserve to rank.
Good SEO isn’t about trying to manipulate Google. It’s about making it easy for search engines to understand what your website offers while providing visitors with useful, relevant information.
When SEO is done well, it can:
- Increase qualified traffic to your website.
- Help more potential customers discover your business.
- Improve trust and credibility.
- Generate more enquiries and sales over the long term.
How Do Search Engines Work?
Before your website can appear in Google’s search results, Google first needs to understand that it exists.
This happens in three main stages.
Crawling
Google uses automated programs, often called crawlers or spiders, to discover pages across the internet.
These crawlers follow links from one page to another, finding new content and revisiting existing pages to check whether anything has changed.
If your website has poor navigation, broken links or pages that are blocked from being crawled, Google may struggle to discover all of your content.
Indexing
Once Google has found a page, it analyses the content and decides whether to store it in its index.
Think of Google’s index as an enormous library containing billions of webpages.
Google looks at many different elements, including:
- Your page content.
- Headings.
- Images and alt text.
- Internal links.
- Page structure.
- Metadata.
If Google can’t understand your content or doesn’t believe it offers enough value, it may choose not to index the page at all.
Ranking
When somebody searches for something, Google doesn’t search the internet in real time. Instead, it searches its index and decides which pages best answer the searcher’s question.
Google considers hundreds of different ranking signals when deciding which pages deserve to appear first. Nobody outside Google knows the exact formula, but years of testing have shown us what consistently helps websites perform well.

Why Keyword Research Comes First
One of the first things I do when working with a new client is keyword research.
This is because there’s very little point optimising a website for phrases that your ideal customer never searches for.
People sometimes become excited about ranking number one for a keyword, but if that keyword never generates enquiries or sales, what have you actually achieved?
Good keyword research focuses on understanding your audience.
What problems are they trying to solve?
What products or services are they searching for?
What language do they actually use?
Only once you know those answers can you start building pages that genuinely match what people are looking for.
Keyword research isn’t just about search volume either. It’s about understanding search intent. Two keywords might look very similar but attract completely different audiences.
Getting this stage right provides the foundation for everything else you do in SEO.
Technical SEO
Once you’ve identified the right keywords, the next step is making sure Google can crawl, understand and trust your website.
This is where technical SEO comes in.
Technical SEO isn’t always the most exciting part of optimisation, but it is one of the most important. If Google can’t properly access your website, even the best-written content can struggle to rank.
Technical SEO covers areas such as:
- Crawlability.
- Indexing.
- Website security.
- Mobile usability.
- Site speed.
- Structured data.
- Internal linking.
- Duplicate content.
We regularly audit client websites because technical issues can appear over time. New pages are added, plugins are updated and websites evolve, so keeping on top of technical SEO is an ongoing process rather than a one-off task.
Creating Content Google Wants to Rank
Content has always played an important role in SEO, but today it’s about much more than simply including your keywords.
Google wants to show the pages that best answer the user’s question.
That means your content needs to demonstrate expertise, provide useful information and satisfy the reason somebody searched in the first place.
Rather than asking yourself, “How many times should I use my keyword?”, ask yourself:
“If I landed on this page, would it answer my question better than the pages already ranking above me?”
That’s the mindset that usually produces the best results.
Google also understands related topics and context far better than it did years ago. You don’t need to repeat the same keyword over and over. Instead, focus on writing naturally and covering the subject thoroughly.

Ultimately, good content is written for people first and search engines second. If your visitors leave your website feeling they’ve found exactly what they were looking for, you’re moving in the right direction.
User Experience Matters More Than Ever
One of the biggest changes I’ve seen since I started working in SEO is Google’s increased focus on user experience.
Years ago, you could often improve rankings simply by optimising keywords and building backlinks. Whilst those things still matter, Google now places much more emphasis on how people interact with your website.
Ask yourself these questions:
- Does your website load quickly?
- Is it easy to navigate?
- Does it work well on mobile devices?
- Can visitors find the information they’re looking for?
- Is your content easy to read?
If the answer is no, you’re making life difficult for both your visitors and Google.
Google wants to recommend websites that provide a positive experience. If users immediately leave your website because it’s slow, confusing or difficult to use, that’s unlikely to help your long-term SEO performance.
Do Backlinks Still Matter?
Backlinks remain one of Google’s ranking signals, but they’re often misunderstood.
A backlink is simply another website linking to yours. Google sees relevant, high-quality links as a sign that other websites trust your content.
However, not all backlinks are good.
Over the years I’ve seen businesses spend thousands of pounds buying links that ultimately did more harm than good.
That’s why I don’t recommend buying backlinks.
Instead, focus on earning links naturally by creating useful content, building relationships within your industry and gaining mentions from reputable websites. A good PR strategy will nearly always deliver better long-term value than trying to manipulate rankings through low-quality link building.
Backlinks still have their place, but they should support a strong SEO strategy rather than become the strategy itself.
SEO Is Never Finished
Another common misconception is that SEO is something you complete once and then forget about.
Unfortunately, it doesn’t work like that.
Google updates its algorithms regularly.
Your competitors improve their websites.
Customer behaviour changes.
Your own business evolves.
All of those things mean your website needs reviewing and improving over time.
One of the easiest ways to lose rankings is to redesign or update your website without considering SEO.
I’ve seen businesses invest heavily in a beautiful new website only to discover they’ve lost months or even years of SEO progress because important pages disappeared, redirects weren’t added or technical issues were introduced during the launch.
Whenever you’re planning a website redesign or major update, I recommend carrying out a full SEO audit beforehand.
Check for things such as:
- Broken links.
- Missing redirects.
- Duplicate content.
- Missing page titles and headings.
- Indexing issues.
- Internal linking opportunities.
Once the new website has been built, test everything before it goes live. Fixing problems before launch is much easier than trying to recover lost rankings afterwards.

How Long Does SEO Take?
This is probably one of the questions I’m asked most often.
The honest answer is that it depends.
Some technical improvements can have an impact within days or weeks, whilst more competitive keywords can take several months to move significantly.
Factors that influence timescales include:
- How competitive your industry is.
- The quality of your existing website.
- Your competitors.
- The amount of work being carried out.
- The authority your website has already built.
Be cautious of anyone promising guaranteed rankings or overnight success.
Good SEO is a long-term investment, and whilst it takes patience, the results are usually much more sustainable than relying solely on paid advertising.
There Are No Shortcuts
SEO has changed enormously since I first started working in the industry, but the fundamentals have remained surprisingly consistent.
Google wants to recommend websites that genuinely help people.
If you focus on creating useful content, maintaining a technically sound website and providing a great experience for your visitors, you’ll already be doing many of the things Google is looking for.
Unfortunately, there are still plenty of outdated ideas about SEO. If you’ve heard advice that sounds too good to be true, it’s worth reading my guide to common SEO myths before putting it into practice.
Is SEO Worth It?
For most businesses, absolutely.
People use search engines every day to find products, services and answers to their questions. Appearing in those search results gives you the opportunity to reach potential customers at exactly the moment they’re looking for what you offer.
Unlike paid advertising, good SEO continues to deliver value long after the work has been completed. That’s why so many businesses see it as one of the best long-term marketing investments they can make.
If you’re just getting started, don’t try to do everything at once.
Focus on understanding your audience, creating helpful content and making your website as useful as possible. Build from there and keep improving over time.
SEO isn’t about finding a secret formula. It’s about consistently doing lots of small things well.
