Search engine optimisation has been around for as long as search engines themselves — and it has changed almost beyond recognition in that time. What worked in 2005 would get your site penalised today. What works today will look different again in five years. Understanding that history matters, because it explains why SEO is the way it is and where the pressure on it is coming from now.
Where SEO began
The first recognisable search engines appeared in the early 1990s. Archie, launched in 1990, indexed FTP files. The World Wide Web Wanderer, created in 1993, was one of the first true web crawlers. By 1994, AltaVista, Yahoo, and Lycos had launched — and with them, the first attempts to game search rankings.
- 1994 — AltaVista launches. Early SEO is almost entirely keyword stuffing and meta tag manipulation.
- 1996 — Larry Page and Sergey Brin begin developing PageRank at Stanford. The idea: links as votes of authority.
- 1998 — Google launches. PageRank makes link building the central SEO strategy for the next decade.
- 2003 — Google Florida Update. Mass penalisation of over-optimised sites. The first major signal that Google would fight manipulation.
- 2011 — Panda Update. Targets thin, low-quality content. Content farms collapse overnight.
- 2012 — Penguin Update. Targets manipulative link building. Bought links stop working.
- 2015 — RankBrain. Google’s first machine learning ranking component. Intent starts mattering more than keywords.
- 2019 — BERT. Google begins understanding natural language at sentence level. Conversational queries handled properly for the first time.
- 2023–2026 — AI Overviews roll out globally. Search results pages begin answering queries directly, without users needing to click.
How search works today
Google remains the dominant search engine globally, handling over 90% of all search queries. For most UK-focused businesses, Google is the only search engine that materially affects organic traffic.
Modern search ranking is determined by hundreds of signals, but the core ones are well understood: content relevance and quality, backlink authority, page speed and Core Web Vitals, mobile usability, and increasingly, user experience signals like dwell time and click-through rate.
The AI Overview problem
Google’s AI Overviews — the AI-generated summaries that appear above organic results — are now visible across more than 200 countries. When an AI Overview is present, click-through rates drop from around 15% to 8%. Organic CTR for queries triggering an AI Overview has dropped 61% year-on-year between mid-2024 and late 2025.
The practical implication: for informational queries — “what is X”, “how does Y work” — AI Overviews are now handling a significant share of the demand that would previously have gone to blog posts and articles. This doesn’t make SEO irrelevant, but it does change what SEO should be optimising for.
- AI Overviews appear on around 25% of all Google searches
- 74% of problem-solving queries now trigger an AI Overview
- Long-tail queries are 60% more likely to trigger an AI Overview than short ones
- Only 1% of users click a link within an AI Overview (Pew Research, 2025)
Despite this, organic search traffic declined by only around 2.5% year-on-year between early 2024 and late 2025 — far less than the “SEO is dead” narrative suggests. The largest sites actually grew organic traffic. The sites losing out are mid-tier publishers producing generic informational content that AI can now replicate.
Voice search in 2026
Over 157 million users in the US interact with voice assistants, and 65% use voice search on a weekly basis. Globally, 1.1 billion mobile users are expected to use voice search weekly.
The SEO implications of voice search optimisation are well established: voice queries are longer, more conversational, and more often phrased as questions. Structuring content to answer specific questions — through FAQ sections, clear headings, and concise answers — improves visibility in both voice results and AI Overviews.
Local SEO and Google Business
For businesses serving a specific geographic area, local SEO remains one of the highest-return channels available. Local searches carry strong commercial intent — someone searching “web designer Manchester” is actively looking to spend money.
Google Business Profile is the central tool for local visibility. Businesses with complete, actively managed profiles appear in the local pack — the map results shown above organic listings for local queries. Reviews, consistent NAP data, and regular posting all influence local rankings.
What SEO looks like now — and where it’s going
The shift happening in SEO isn’t that it’s dying — it’s that the tactics that worked are changing faster than they used to. The fundamentals remain: create content that genuinely answers what people are searching for, earn links from credible sources, ensure the technical foundations of your site are sound, and make the user experience good enough that people stay and engage.
What’s changing is the context around those fundamentals. AI search tools are handling more informational queries directly. Brand search and navigational queries are becoming a larger share of valuable organic traffic. Appearing in rich results and AI-generated answers requires structured data, clear content, and demonstrable expertise.
The businesses that will do well in search over the next five years are those producing content that AI can’t replicate: original research, genuine expertise, first-hand experience, and strong brand signals. The era of ranking on volume of generic content is over. The era of ranking on quality and authority is more important than ever.
