What is SEO?

SEO (Search Engine Optimization) covers every tactic used to improve a website's visibility in the organic (unpaid) search results of search engines such as Google and Bing — and increasingly of AI answer engines like ChatGPT, Perplexity and Google AI Overviews. The goal: when someone searches a relevant query, your site appears as high as possible — ideally position 1, or at least on page one.

Why it matters: the first three Google results capture more than 55% of all clicks combined, with position 1 alone taking around 27%. Anything beyond page one is essentially invisible. Unlike paid ads, which only run while the budget lasts, SEO compounds — a strong article can drive traffic for years at zero marginal cost.

The 3 pillars of SEO

  1. Technical SEO: Page speed (Core Web Vitals), mobile-friendliness, clean site architecture, HTTPS, sitemap, robots.txt, structured data (Schema.org), no broken links, and crawlability for search bots
  2. On-page SEO: Keywords in the right places (title, H1, first 100 words), meta descriptions, descriptive URLs, internal linking, content depth and quality, image alt text, and a clean heading hierarchy
  3. Off-page SEO: Backlinks from trustworthy sites, social signals, brand mentions (even unlinked), local listings (Google Business Profile), reputation and authority

Key SEO concepts

  • Keywords: The queries you want to rank for. Distinguish head terms ("shoes", high competition) from long-tail queries ("best waterproof hiking shoes for women", lower competition, higher purchase intent)
  • Search intent: What does the user actually want? Informational ("what is SEO"), navigational ("publy.ch"), commercial ("best SEO tools") or transactional ("buy SEO tool")
  • E-E-A-T: Experience, Expertise, Authoritativeness, Trustworthiness — Google's content quality framework. Especially critical for YMYL topics (Your Money or Your Life)
  • Core Web Vitals: Google's performance metrics — LCP (loading), INP (interactivity), CLS (layout stability)
  • Crawl budget: How often Google revisits your site — important for large sites

SEO for small businesses: the highest-leverage moves

Small businesses rarely beat large competitors on generic head terms — and they don't have to. The wins come from:

  • Local SEO: Optimise the Google Business Profile, keep NAP (name, address, phone) consistent, collect reviews, target local intent ("bakery Brooklyn")
  • Long-tail content: Answer the specific questions your audience actually types, the ones big brands ignore
  • Niche expertise: Deep articles on a tightly-defined topic outperform thin all-rounder content
  • Internal linking: Connect related articles so Google understands your topical authority

How SEO and social media reinforce each other

Social and SEO don't compete — they amplify each other:

  • Social content can earn backlinks when bloggers and journalists pick it up
  • Strong content gets shared, increases brand awareness, drives more brand searches, and lifts brand-keyword rankings
  • Social profiles (LinkedIn, Instagram, YouTube) usually rank in the top 3 alongside your website on brand searches
  • Use social as a low-cost testbed for blog ideas — what gets engagement there often works as long-form content
  • YouTube videos can appear as video snippets in Google SERPs and pull traffic to your site

GEO: Generative Engine Optimization

Since 2024, optimising only for classic search engines is no longer enough. AI answer engines (ChatGPT, Perplexity, Google AI Overviews, Bing Copilot) cite websites as sources — and being cited drives both visibility and qualified traffic. Key GEO factors:

  • llms.txt: A structured site description aimed at AI crawlers
  • Citable content: Short, precise paragraphs that work well as a snippet
  • Clear author attribution: E-E-A-T signals matter for AI engines too
  • Don't block AI crawlers: Allow GPTBot, ClaudeBot, PerplexityBot in robots.txt

Common SEO mistakes

  1. Keyword stuffing: Cramming keywords leads to penalties today
  2. Thin content: 200-word articles barely rank in 2026
  3. Ignoring page speed: Slow sites lose both users and rankings
  4. Duplicate content: The same text on multiple URLs without a canonical tag
  5. Buying backlinks: Risk of a manual Google penalty
  6. Skipping meta descriptions: A free chance at a higher SERP click-through rate left on the table
