What Is SEO and How Does it Work?

If you’ve ever asked yourself, “Why does one website show up first on Google while another barely gets seen?”, the answer is SEO. So, what is SEO and how does it work in practical terms? At Johnston Marketing, we help businesses understand and use SEO to drive targeted traffic, build visibility, and generate consistent enquiries.

What Is SEO?

SEO stands for Search Engine Optimization. It’s the process of improving your website so that it appears higher in search engine results for relevant searches. The better your SEO, the more likely it is that potential customers will discover your business when they’re actively looking for what you offer.

In simple terms: SEO helps the right people find you online without paying for ads.

At Johnston Marketing, we take a strategic approach to SEO. That means improving your technical setup, optimising your content, and positioning your brand as trustworthy and relevant in the eyes of search engines.

How Does SEO Work?

To understand how SEO works, it helps to know what search engines actually do. Search engines like Google use automated programs, often called crawlers, to scan the internet and collect information about web pages. That information is stored, analysed, and then ranked whenever someone types in a search.

Here’s what happens step by step:

1. Crawling

Search engines send crawlers to discover your pages. They follow links, scan your site structure, and gather data. If your website is easy to navigate and technically sound, it’s easier for these crawlers to access and understand your content.

2. Indexing

After crawling, your content is added to the search engine’s index. During indexing, the search engine tries to understand what each page is about, which topics you cover, and which keywords are relevant.

3. Ranking

When someone searches for a phrase, like “marketing support for small businesses,” the search engine instantly ranks all relevant indexed pages. Pages considered most useful, trustworthy, and relevant are placed higher. Effective SEO aims to make sure your website appears in those top results.

So when we talk about what is SEO and how does it work, this is the core idea: you’re aligning your website with what search engines consider valuable.

The Main Parts of SEO

At Johnston Marketing, our SEO approach is built on three key areas that work together to deliver long-term results.

On-Page SEO

On-page SEO is everything we optimise directly on your website. This includes using the right keywords, writing high-quality page content, structuring headings, and improving title tags and meta descriptions.

We make sure every page on your site sends clear, relevant signals to both customers and search engines. Our team at Johnston Marketing also performs in-depth keyword research so your site targets the exact search terms your ideal audience is already using.

Off-Page SEO

Off-page SEO focuses on building your credibility across the web. This often includes earning high-quality backlinks and strengthening your brand reputation. When other reputable sites point to your website, search engines view you as more authoritative.

Johnston Marketing develops off-page strategies that position you as a trusted source in your space and help improve your rankings over time.

Technical SEO

Technical SEO is about performance and accessibility. Search engines prefer websites that load quickly, work smoothly on mobile, and are secure. Clean code, fast speed, and clear structure all make it easier for search engines to understand and rank your pages.

We handle this technical foundation for you. From crawlability to mobile experience, Johnston Marketing ensures your site is built for both users and search engines.

Why SEO Matters

Strong SEO is one of the most effective ways to grow your business online. Most buying journeys begin with a search, and most people click one of the first few results. If you’re not showing up where your potential customers are looking, your competitors are.

Done properly, SEO helps you:

  • Bring in qualified leads who are already interested in what you offer
  • Build trust and authority in your market
  • Increase brand visibility and awareness
  • See better long-term return than traditional outbound marketing

Unlike paid ads, SEO keeps working over time. When your site ranks well, you continue to attract visitors without having to pay for every single click.
