SEO 101

Introduces the core practices for improving a site's organic visibility in search engines: ensuring crawlability, relevance, user value, and authority.

If you think SEO is just keyword placement, you miss the technical and authority signals that actually determine rankings.

Key points

  • Start with crawlability: search engines must be able to discover and read your pages via links and sitemaps.
  • Create high-quality, user-focused content that directly answers the queries people actually search for.
  • Optimise titles, descriptions, URLs, and images for clarity, relevance, and search intent.
  • Earn reputable inbound links as trust signals; avoid spammy or low-quality link schemes.

A beginner's first SEO fix

A new vegan recipe blog had 10 pages of duplicate content, no title tags, and a disallow all in robots.txt. After removing the block, writing 20 unique recipes with descriptive titles and meta descriptions, and getting a mention from a food blogger, organic traffic went from zero to 150 visits per month within two months.

Three things SEO 101 is not

  • Not a one-time fix SEO requires ongoing monitoring and updates as search algorithms, user behaviour, and your own site change over time.
  • Not just keyword stuffing Modern SEO prioritises content quality and user intent over exact-match keywords; thin or irrelevant keyword repetition harms rankings, as SEO history has shown.
  • Not paid advertising SEO targets organic, non-paid search results. You cannot pay Google to rank higher organically; that is what Google Ads does.

Three ways beginners go wrong

  • Blocking important pages Using robots.txt or noindex on pages you want indexed, or blocking CSS/JS resources that search engines need to render content.
  • Publishing thin content Creating short or duplicate pages that fail to fully answer the searcher's query — a common topic SEO mistake — resulting in low engagement and poor rankings.
  • Chasing low-quality links Buying links or participating in link schemes can trigger manual penalties; focus on earning relevant, authoritative mentions instead.

Three core areas to focus on

  • Crawlability and indexing Ensure search engines can discover your pages via sitemaps, internal links, and accessible resources. Check for crawl errors in Search Console — a foundational step in any 3 month SEO plan.
  • Content relevance and quality Create unique, user-focused content that matches search intent. Use keyword research to align topics with what people actually search for.
  • Authority and trust signals Earn reputable inbound links and mentions. Google treats these as signals of trustworthiness and expertise. Following a consistent SEO process helps you identify and attract such links.
