Understanding SEO: A Simple Guide to Essential Terms
Search Engine Optimisation (SEO) is one of the most powerful ways to grow your online presence, but the terminology can often feel overwhelming. Whether you're a business owner looking to improve your search rankings or a marketing professional wanting to sharpen your SEO knowledge, this glossary will help you navigate the most important terms.
By understanding these key concepts, you'll be better equipped to make informed decisions about your website’s optimisation, user experience, and long-term digital strategy. Let’s break it all down.
Essential SEO Terms You Should Know
301 Redirect
A permanent redirect that automatically takes users (and search engines) from one URL to another. Used when moving pages or restructuring a site without losing SEO value.
404 Not Found
An error message that appears when a page can’t be found, often due to broken links or removed content. Too many 404 errors can negatively impact user experience and SEO.
Anchor Text
The clickable text in a hyperlink. Effective anchor text gives search engines context about the linked page and improves internal linking strategies.
Backlink
A link from another website to yours. High-quality backlinks signal to search engines that your content is trustworthy and authoritative, helping improve rankings.
Black Hat SEO
Unethical SEO tactics that attempt to manipulate rankings in search engines, often violating guidelines. These include keyword stuffing, cloaking, and link schemes. Google penalises sites that use black hat SEO.
Bounce Rate
The percentage of visitors who leave a site after viewing only one page. A high bounce rate could indicate poor user experience, slow loading speed, or irrelevant content.
Canonical URL
A preferred version of a webpage that prevents duplicate content issues. Used when multiple pages have similar content to ensure search engines index the correct one.
Crawlers (Search Engine Bots)
Automated programs used by search engines to scan and index website content. Also known as spiders or bots, they help search engines determine how pages should rank.
Keyword
A word or phrase that users type into search engines to find information. Proper keyword research and implementation improve search rankings and attract targeted traffic.
Link Building
The process of acquiring high-quality links from other websites to boost your site’s authority and search visibility.
Meta Description
A short summary that appears under a webpage’s title in search engine results. It helps improve click-through rates by giving users a preview of the page’s content.
NoIndex Tag
A directive that tells search engines not to index a particular page. Useful for preventing duplicate content issues or keeping certain pages private.
On-Page SEO
Optimisations made directly on your website, including content, meta tags, headings, internal links, and mobile-friendliness.
Off-Page SEO
Factors that impact rankings from outside your website, such as backlinks, social signals, and brand mentions.

Page Speed
How quickly your website loads for visitors. Faster websites improve user experience and can positively impact SEO rankings.
Ranking

The practice of optimising a website to improve its visibility in search engine results. SEO includes technical, on-page, and off-page strategies.
SERP (Search Engine Results Page)
The page displayed by search engines after a user enters a query. It includes organic results, paid ads, and featured snippets.
Sitemap
A file that lists all the important pages on your website, helping search engines discover and index them more efficiently.
