How Search Engine Optimisation Is Different to Online Marketing
- Written by Times Media

In the digital world, businesses often hear the terms search engine optimisation (SEO) and online marketing used interchangeably. While both aim to attract customers through digital channels, they are distinct disciplines with different strategies, goals, and metrics. Understanding the difference is essential for anyone wanting to build a strong online presence and achieve sustainable business growth.
The Core Definition of SEO
Search Engine Optimisation, or SEO, refers to the process of improving a website’s visibility on search engines like Google, Bing, and Yahoo. The main goal is to increase organic (non-paid) traffic by making a site more relevant and accessible to users and search engine algorithms.
SEO typically involves three main areas:
-
On-Page SEO: Optimising website content, titles, meta tags, URLs, and internal links to improve search rankings.
-
Off-Page SEO: Building backlinks and improving the site’s reputation through other websites, directories, and online mentions.
-
Technical SEO: Ensuring a site is fast, mobile-friendly, and easily crawlable by search engines.
In essence, SEO focuses on aligning a website’s structure and content with what search engines consider valuable and trustworthy. It is a long-term strategy designed to improve organic visibility and sustain traffic without ongoing advertising costs.
The Broader Scope of Online Marketing
Online marketing (or digital marketing) is a much broader concept. It encompasses all the ways a business can promote itself online — both paid and organic. SEO is just one component within this larger ecosystem.
Online marketing includes:
-
Search Engine Marketing (SEM): Paid ads that appear on search engines (e.g., Google Ads or Bing Ads).
-
Social Media Marketing: Using platforms like Facebook, Instagram, TikTok, or LinkedIn to build brand awareness and drive engagement.
-
Email Marketing: Sending newsletters or promotional emails to nurture leads and encourage repeat sales.
-
Content Marketing: Creating valuable articles, videos, or infographics that attract and educate audiences.
-
Affiliate and Influencer Marketing: Partnering with individuals or organisations who promote your brand for a commission or fee.
-
Display Advertising and Retargeting: Using banner ads or targeted campaigns to reach potential customers across websites.
In short, online marketing is a comprehensive approach to reaching customers wherever they are on the internet, combining multiple tools and channels to create a cohesive brand experience.
