What is SEO, Really? A Plain-English Guide

Most people who come to me already know that SEO stands for Search Engine Optimisation, and that – at its most basic level – it means “getting found on Google”. What they may not understand is:

  • Why it’s not just about Google
  • What SEO involves
  • Why it takes time
  • Why it’s not just about keywords
  • Why technical health matters
  • Why content needs strategy
  • Why rankings alone are not the whole point
  • Why a new website doesn’t come with SEO built-in

Let’s set it all in plain English.

What SEO actually means

We can sum it up with the following definition:

“SEO is the practice of improving your website so that search engines – and increasingly AI-powered search tools – can understand it, trust it, and show it to the right people at the right time.”
Mandy Cochrane

Google was (and still is) by far the search engine with the biggest market share, with Bing and others sharing a much smaller slice of the pie.

In the age of AI, there are now far more platforms on which to be visible, although Google continues to dominate, even as the popularity of AI interfaces such as ChatGPT grows.

What SEO is not

If I had a pound for every time someone said to me, “Can you just SEO this bit..?”, I’d be a rich woman. The truth is, there’s no magic button, no secret process that only us SEOs know about. A plugin or automated software can’t do it for you, and if your SEO “expert” has talked you into a pick-and-mix package with Bronze, Silver and Gold labels, sorry, you’ve been sold a pup.

Misconceptions about SEO often lead to wasted budgets, failed marketing strategies, and penalties from search engines, so here’s a quick sum-up of what SEO isn’t.

SEO is not just installing Yoast or Rank Math: Plugins can help with some on-page checks, but they don’t create a strategy, understand your audience, fix weak content, or decide what work matters most.
SEO is not chasing traffic for the sake of it: A thousand irrelevant visits are less useful than a smaller number of visitors who are genuinely looking for what you offer.
SEO is not a one-off tidy-up: Audits and fixes are valuable, but the strongest results usually come from ongoing improvement, measurement and refinement.
SEO is not a way to cheat search engine algorithms for instant traffic: Good SEO works within search engine guidelines; shortcuts and “black hat” tactics may look tempting, but they can put your visibility at risk.
SEO is not paid advertising: SEO focuses on visibility in organic search results. Paid advertising can be valuable too, but it’s a separate strategy. Paying for Google Ads does not directly improve your organic rankings.
SEO is not cheap. There, I said it! An SEO consultant worth their salt has experience and expertise that puts them on a par with any other professional person. Their decisions and advice impact the success of your business, which is a huge responsibility. Be wary of cheap service offerings, especially if they promise the earth.
SEO is not a pick-and-mix sweet shop. Done right, SEO is a holistic effort that combines on-site, off-site, technical and local SEO elements. Would you expect your car to run properly if you fixed its tyres but left the battery uncharged and the exhaust on the floor? Don’t expect SEO to work if you choose a cheap Local SEO service, but decide not to fix poor quality on-site content or improve page-load speed.

What good SEO should achieve

Effective SEO should help your site achieve two goals:

  1. To attract more free, organic (unpaid) traffic from people when they are actively searching for your specific products, services, or information. SEO should provide you with strong, long-term visibility that drives relevant visitors, more qualified leads and conversions, and clearer journeys through your site.
  2. Increasingly, good SEO can also improve the chances of your brand or content being referenced in AI-generated answers, particularly when your site demonstrates clear expertise, authority and usefulness.

For clarity – some people describe the practice of improving a site’s visibility in AI-generated answers as GEO (Generative Engine Optimisation). At the moment, I prefer to stick with one acronym, SEO, because the strategies for SEO and GEO are effectively very similar. I could get on my soap-box about that particular debate, but I’ll save it for a different article!

Why SEO matters for businesses

  • Free (“organic”) traffic: Unlike paid advertising (such as Google Ads), you don’t pay the search engine when someone clicks the link to your site in search results or an AI citation.
  • High-intent visitors: If your site shows up prominently when people are actively searching for specific solutions, products, or answers, they are more likely to convert into customers.
  • Long-term value: Paid ads stop generating traffic the moment you stop paying, but high quality, well-ranked organic content could attract targeted visitors for months or even years*.

*For example, I originally wrote this article for an SEO client around 2013, and – with a few updates since – it’s still one of the most visited pages on their site.

How search engines work

It might seem a little boring, but to understand SEO, it’s important to at least have a rudimentary idea of how platforms like Google put together search results:

  1. Crawling: Search engines use automated software programs called “crawlers” or “bots” to constantly explore the web and discover new or updated pages.
  2. Indexing: With so much content being published now, search engines are increasingly evaluating each new piece they discover to decide what value it offers. If a discovered page is sufficiently useful, unique, or interesting, search engines store and organise it in a massive database called a search index. You could think of it as a vast digital library.
  3. Ranking: When a user enters a query, search engines use complex algorithms to evaluate hundreds of quality signals across the index, deciding which are the most relevant and high-quality results to display.

Basic SEO strategies

SEO can be complex, involving many tasks over a period of time, but an effective SEO strategy can be broken down into four distinct areas of focus:

Focus AreaWhat It Focuses OnCommon Actions
On-Page SEOOptimising visible content on individual pages.Writing high-quality, well researched content, using relevant keywords, and organising headings.
Technical SEOImproving back-end site infrastructure for search engine and AI crawlers.Boosting page load speed, fixing broken links, and ensuring mobile-friendliness.
Off-Page SEOBuilding your website’s reputation and authority.Earning backlinks (links from external sites) and managing brand mentions.
Local SEOCapturing location-based search traffic for local service-providers and retailers.Optimising your Google Business Profile and targeting “near me” queries.

1. On-Page SEO (Content)

This involves optimising the actual words, pages, images, videos and other media on your site to help both humans and search engines easily understand them.

  • Topics and Keywords: Researching and writing about the exact topics and keywords your audience is searching for; spotting gaps that your competitors haven’t taken advantage of yet. A well-researched and implemented content strategy is your bible for this element of SEO.
  • Search Intent: Understanding what information your audience needs. What questions do they have while they’re researching a service or product? What pain-points or obstacles might prevent them converting? When you understand the reasoning and the intent behind a user’s search, you can create content that thoroughly meets their needs at every stage of their journey through your website.
  • Quality, Expertise and Experience: Google’s quality rater guidelines refer to experience, expertise, authoritativeness and trustworthiness, often shortened to EEAT. In plain English, this means your content should make it clear that you know what you’re talking about and can be trusted.

2. Technical SEO (Essential Foundations)

I know, I used the word “technical”! But please bear with me, I promise I’m not getting geeky. This is often the part of SEO people only notice when something is going wrong – pages not appearing in Google, the site feeling slow, or important content being buried too deeply for users and search engines to find easily.

Technical SEO focuses on the back-end elements of your website – often things a user can’t see when they visit – to ensure search engines can easily find, crawl, and index your pages. Many of these technical elements are ranking factors.

  • Site Speed: Optimising web pages to load as quickly as possible.
  • Mobile-Friendliness: Ensuring the site functions perfectly on any size screen, e.g. desktop monitors, laptops, smartphones and tablets.
  • Site Structure: Using clean URLs and logical navigation so bots can easily browse your site.

3. Off-Page SEO (Trust and Reputation)

This is less tangible, less easy to control. It involves building your website’s credibility, authority and reputation across the wider internet.

  • Backlinks: Earning links from other well-known, high-quality websites. Search engines view links to your site as “votes of confidence,” and over time, they can signal that your site is trustworthy. This might involve creating genuinely useful resources that other sites have a reason to reference, or building relationships with relevant organisations, publications or industry partners.
  • Reviews: Independent reviews of your business on reputable platforms such as Google Reviews, Trustpilot, Feefo, etc. can underline your expertise, experience or high service levels, which again, search engines use as a signal of the value of your site. It should be a regular part of your post-service or post-sale routine to reach out to customers for a review.

4. Local SEO

Local SEO optimises your website’s online presence to attract more business from local searches. It’s an important focus area for small businesses, physical store-fronts, or service-area businesses such as plumbers or electricians.

  • Key Practices: Claiming and optimising a Google Business Profile, generating positive customer reviews, getting listed in local online directories, and using localised keywords on web pages.

To build a truly effective digital strategy, all four focus areas of SEO must work together. Search engines evaluate hundreds of ranking signals – although not all have equal weight – and so it’s important to work on every area regularly as part of an ongoing SEO project.

Measurement

As well as these four basic focus areas, an often-overlooked aspect of SEO is measurement. It’s impossible to know how effective your SEO strategies are, and to prioritise the next steps, unless you have a baseline of where you started, and regularly track progress over time.

I use a mix of analytics, search performance, auditing, local SEO and user behaviour tools to track what is changing and why.

I also keep detailed records of every change made to a site, as well as new content published, with dates, to have some way of associating both good and bad performance impacts with actions on the site.

Why SEO takes time

There are several reasons why patience is a virtue with SEO.

  • The four main pillars of SEO outlined above take time to implement. It’s a great deal of work, although AI tools – used correctly – help speed up some aspects of it these days.
  • SEO sets out to improve how your website is understood, trusted, and structured to match real search intent – that happens over time, and relies on search engines and users to react positively to those gradual changes.
  • Every improvement you make to your site can take time to be reflected in search results. If Google crawls your site frequently (more common on larger sites that are updated frequently), some changes might take effect in a few hours, but others could take several months, for example the next time Google updates an aspect of their algorithm.

Not every change will make a difference

Keep in mind that not all changes you make to your website will have a noticeable impact in search results. Part of the skill involved with SEO is understanding what changes are likely to be beneficial, and prioritising the work that will have the most impact. For example, a new blog post on a topic that has been covered multiple times elsewhere must either bring some fresh angle to that topic, or else raise the bar in the quality of its coverage to have any hope of it performing well in search.

If you’re not happy with the impact you’re getting from your efforts, it could be worth discussing a fresh approach to your SEO strategy.

What next?

For anyone interested in learning about SEO themselves, Google itself has published an easy-to-read SEO starter guide, Google Search Essentials, which I highly recommend to understand exactly how search engines discover and rank websites.
