What is SEO?

Search Engine Optimisation has changed dramatically since the early days of keyword stuffing and link farms. In 2026, SEO is a multidisciplinary practice that blends technical performance, content quality, user experience, and an understanding of how AI is reshaping search itself.

Here is what effective SEO looks like today.

Core Web Vitals: Performance Is a Ranking Signal

Google has made it explicit: page performance matters. Core Web Vitals measure three key user experience metrics: Largest Contentful Paint (how fast the main content loads), Interaction to Next Paint (how quickly the page responds to user input), and Cumulative Layout Shift (visual stability as the page loads).

A slow, unstable page will underperform in search regardless of how good the content is. Technical performance is now foundational to SEO, not optional.

E-E-A-T: The Trust Framework Google Uses to Evaluate Content

Google evaluates content through the lens of Experience, Expertise, Authoritativeness, and Trust. The addition of Experience to the original E-A-T framework reflects a shift toward valuing first-hand, lived knowledge rather than just academic credentials.

For small businesses, this means writing content from genuine experience and specific knowledge, demonstrating who wrote the content, building a consistent trustworthy brand presence online, and earning legitimate backlinks from reputable sources.

AI and Search: How Google AI Overviews Are Changing the Game

Google AI Overviews now appear at the top of search results for many queries, generating direct answers before users even reach organic listings. This has shifted the goal for many searches from ranking number one to being cited in the AI overview.

Content that is structured clearly, answers questions directly, and demonstrates expertise is most likely to be referenced by AI-generated summaries. Clear headings, concise answers, and authoritative content matter more than ever.

Technical SEO: The Foundation Beneath Everything

Technical SEO ensures that search engines can properly find, crawl, and index your site. Key areas in 2026 include mobile-first indexing (Google indexes and ranks sites based on their mobile version), structured data and schema markup (helps Google understand your content and unlocks rich results like review stars and FAQs), clean URL structures and logical internal linking, and HTTPS security which is a baseline requirement for every site.

Content Quality Over Keyword Density

The era of writing for algorithms is over. Modern SEO requires content that genuinely helps the reader. Keyword research still matters for understanding what your audience is searching for, but the goal is to create content that serves those searchers, not to hit a keyword count. Thin, generic content is actively penalised. In-depth content that addresses the full scope of a topic performs significantly better.

Local SEO: Critical for Businesses Serving a Geographic Area

If your business serves customers in a specific city or region, local SEO is essential. This means optimising your Google Business Profile, earning local citations, building location-specific content, and generating genuine customer reviews. Local search now often surfaces AI-generated answers that pull directly from Google Business data, which is another reason to keep your listing accurate and active.

Voice Search and Conversational Queries

With AI assistants embedded in phones, speakers, and browsers, more searches are now spoken and conversational. Optimising for natural language queries through FAQ content, clear headings, and conversational writing improves visibility for voice and AI-assisted search.
