What Is SEO and Why Is It Important for Research and Knowledge-Based Businesses?

SEO, or Search Engine Optimization, is the process of improving a website’s visibility in organic search results. It focuses on technical optimisation, content relevance, site structure, and authority signals that help search engines rank pages accurately.

In 2026, SEO success depends on trust, clarity, and performance. Google prioritises websites that demonstrate expertise, load quickly, and clearly communicate complex information. For healthcare providers, research organisations, and SaaS companies, SEO is a long-term channel for credibility and inbound growth.
