1. What is SEO?

Search Engine Optimisation is the practice of enhancing your website to increase its visibility for relevant searches. The better visibility your pages have in search results, the more likely you are to attract attention and drive prospective and existing customers to your business.


2. Why SEO Matters

2.1. Increased Visibility and Traffic

Higher rankings on search engine results pages (SERPs) lead to increased visibility, which can result in more website traffic.

2.2. Builds Credibility and Trust

Websites that rank well are generally perceived as more trustworthy and credible by users.

Unlike paid advertising, organic SEO traffic is free. Investing in SEO can yield long-term benefits at a relatively low cost.

SEO involves improving site structure and content, which enhances user experience and increases engagement.

Understanding how search engines operate is essential to effectively optimise your website.

3.1. Crawling

Search engines use bots, known as crawlers or spiders, to discover new and updated content by following links on web pages.

3.2. Indexing

Once content is discovered, it's stored and organised in an index—a massive database of web pages.

3.3. Ranking

When a user performs a search, search engines provide results by ranking pages based on relevance and quality, using complex algorithms.
