SEO (Search Engine Optimisation) is the practice of structuring your website, content, and external signals so search engines (Google, Bing, increasingly AI Overviews) rank you higher for relevant queries. It splits into: technical SEO (site structure, speed, schema), on-page (content matching search intent), off-page (links, brand signals, citations), and now AEO (answer engine optimisation for AI citations) plus GEO (geographic / local SEO). In 2026, ranking matters less than being cited — AI Overviews appear on 25–35% of commercial queries and divert clicks away from rank-1.
1. Technical SEO: site speed (Core Web Vitals: LCP, CLS, INP), crawlability, indexability, schema markup, internal linking architecture, mobile responsiveness.
2. On-page SEO: matching content to search intent, keyword research, title / H1 / meta optimisation, structured headings, image alt text, internal links to relevant resources.
3. Off-page SEO: backlinks from authoritative sites, brand mentions and citations, online reviews and reputation, social signals (lower weight but real).
4. AEO + GEO: AEO = optimising content for citation by AI Overviews, ChatGPT, Perplexity. GEO = local 3-pack capture via Google Business Profile, NAP consistency, borough-specific content.
AI Overviews now appear on 25–35% of commercial queries. Click-through rate on rank-1 organic drops by 30% when an AI Overview is present. Zero-click rate on Google searches is 60% generally and 80%+ on AI-Overview queries.
Implication: ranking for keywords matters less. Being cited by the AI Overview matters more. AEO tactics: lead with direct answer, use structured data (FAQPage, HowTo, Article schema), cite authoritative sources, date-stamp content.
"Optimising for rank-1 alone in 2026 is shrinking your TAM. Optimise for citation. The traffic doesn't go to your site — the trust does, and warm leads who saw the citation convert better than cold rank-1 clicks."
First rank movement: 6–12 weeks. First meaningful organic traffic: 3–6 months. First strong revenue contribution: 6–12 months. Compounding flywheel kicks in around month 12–18.
This is why SEO is patient money. Anyone promising 'top of Google in 30 days' is either lying or using paid placement disguised as organic.
Monthly: technical audit follow-through (page-speed fixes, schema, internal links), content (4–8 articles or page improvements), link acquisition (4–8 quality links), reporting tied to your KPIs.
Quarterly: full technical audit refresh, topical authority review, competitive gap analysis, backlink audit.
Annual: site-architecture review, content audit (deindex thin pages, refresh dated content), keyword universe re-mapping.
DIY SEO works for: (1) solopreneurs with time but no budget, (2) writers and consultants whose product is content, (3) anyone willing to invest 5–10 hours/week for 18+ months.
Agency SEO works for: (1) businesses where SEO is an acquisition channel but not the team's core competence, (2) anyone above £500k revenue where senior strategy time pays back fast, (3) e-commerce / SaaS where speed of execution matters.
