When you launch a new website for your business, you will likely hear terms like "SEO", "indexing", "keywords", and "meta descriptions". These terms can feel technical, but the underlying ideas are straightforward. Understanding them helps you have more productive conversations with your web team and marketing partners, and gives you a clearer picture of how your website gets found by potential customers.
This article explains the most common SEO terms in plain language. All definitions are consistent with Google's own Search Central documentation (developers.google.com/search/docs), which is the authoritative source for how Google Search works.
What Is SEO?
SEO stands for Search Engine Optimisation. It is the practice of making a website easier for search engines — primarily Google — to find, understand, and rank, so that people searching for your product or service are more likely to find your site in the results.
SEO is not a single action; it is a combination of technical setup, content quality, and ongoing maintenance. A well-built website with clear, relevant content has a strong SEO foundation from the start.
Key Terms Explained
Crawling
Crawling is the process by which search engine programs — called crawlers or bots (Google's is called Googlebot) — discover web pages by following links across the internet. When Googlebot visits your website, it reads the page content and follows links to other pages on your site and beyond.
A page that has not been crawled cannot appear in search results. This is why having a well-linked site structure matters — it helps crawlers find all of your pages.
Indexing
Indexing is the step after crawling. Once Googlebot has crawled a page, Google processes and stores the page's content in its database — the index. Only indexed pages are eligible to appear in search results.
If a page is crawled but not indexed, it means Google found the page but decided not to include it in the index — this can happen if the page has very thin content, is a duplicate of another page, or has technical issues.
Search Results and SERP
SERP stands for Search Engine Results Page — it is the page Google shows when someone performs a search. The SERP contains a list of results that Google considers relevant to the search query.
Results are divided into two main types: organic results (non-paid listings influenced by SEO) and paid results (advertisements, typically labelled as "Sponsored"). SEO focuses on improving your position in the organic results.
Ranking
Ranking refers to a page's position in the organic search results for a given search query. A page that ranks higher appears closer to the top of the results, which means more people are likely to see and click on it.
Ranking is influenced by many factors, including the relevance and quality of the page's content, the site's technical health, and signals from other websites linking to the page.
Keyword
A keyword is a word or phrase that a user types into a search engine. For example, if someone searches for "IT support Cape Town", that entire phrase is the keyword.
Effective SEO involves understanding which keywords your potential customers use and ensuring that your website content addresses those topics clearly and naturally. This does not mean repeating the same phrase over and over — Google specifically advises against keyword stuffing, which is the practice of unnaturally overloading a page with keywords.
Page Title (Title Tag)
The page title — also called the title tag — is the clickable headline that appears in search results. It is one of the most important on-page SEO signals. Each page on your website should have a unique, descriptive title that accurately reflects the page's content.
A good page title tells both the searcher and Google what the page is about. For example, "IT Support Services in Cape Town | Your Business Name" is more useful than "Home" or "Welcome".
Meta Description
The meta description is the brief summary text that appears below the page title in search results. It does not directly affect your page's ranking, but it does influence whether a searcher decides to click through to your site.
A well-written meta description is concise (typically under 160 characters), relevant to the page content, and gives the reader a reason to visit the page.
Backlink
A backlink is a link from another website to yours. When a reputable, relevant website links to your site, it acts as a signal to Google that your content is trustworthy and valuable.
Not all backlinks are equal — a link from a respected industry publication or a local business directory carries more weight than a link from an unrelated or low-quality site. Building high-quality backlinks happens naturally over time as you create useful content and build your online presence.
Core Web Vitals
Core Web Vitals are a set of performance metrics defined by Google that measure the user experience of a web page — specifically how fast the main content loads, how quickly the page responds to interaction, and whether the layout shifts unexpectedly while loading.
A poor Core Web Vitals score can negatively affect a page's ranking. Google provides a free tool called PageSpeed Insights (pagespeed.web.dev) that measures these metrics for any URL.
Structured Data and Schema Markup
Structured data — also called schema markup — is machine-readable code added to a web page that helps Google understand the content type. For example, structured data can tell Google that a page describes a product, a business address, a review, or an event.
When structured data is implemented correctly, it can enable enhanced search result features called rich results — such as star ratings, product prices, or event dates displayed directly in the search results.
Sitemap
A sitemap is a file — usually named sitemap.xml — that lists all the pages on your website. Submitting your sitemap to Google Search Console helps Googlebot discover all of your pages efficiently, especially on a new site where not many external links exist yet.
Most modern website platforms and content management systems generate a sitemap automatically.
Google Search Console
Google Search Console is a free tool provided by Google that shows how your site is performing in Google Search. It tells you which search queries are bringing people to your site, which pages are indexed, and whether any pages have errors that prevent them from appearing in results.
It is the primary diagnostic tool for monitoring your site's SEO health. Access is free — you just need to verify ownership of your domain.
