SEO Optimised

Adjusts a webpage’s content, structure, and HTML so search engines can understand it and rank it for relevant queries.

If you think SEO Optimised means you just need to add keywords to your page, you are missing the broader goal of relevance, structure, and user experience.

Key points

  • Start with the page’s purpose and audience, not just keywords.
  • Include clear headings and descriptive URLs to help search engines parse your content.
  • Optimise images by using descriptive filenames and alt text.
  • Avoid duplicate content; each page should be unique and offer its own value, not just rephrase what others have written.
  • Use internal links to guide users and search engines to related pages.
  • Follow basic SEO tips like keeping titles concise and matching content to user intent for better visibility.

A travel blog post transformed

A blog post about 'best hikes in Scotland' was not SEO Optimised: it had a vague title, no headings, and images named 'img456.jpg'. After adding a descriptive URL, an H1 matching the query, subheadings, and alt text like 'hikers on the West Highland Way', the page rose from page 5 to page 2 for its target term. The content itself had always been strong; the structure and HTML were the missing links in the SEO process. The author also incorporated off-page SEO techniques like building backlinks from outdoor forums, and studied SEO history to avoid outdated tactics from 2014.

Three common mistakes when aiming for SEO Optimised

  • Keyword stuffing Repeating a target phrase unnaturally hurts readability and can trigger spam filters. Search engines value user-first, helpful content over forced repetition.
  • Ignoring HTML elements Optimising only body copy while leaving title tags, meta descriptions, headings, URLs, and image alt text unoptimised misses critical signals.
  • Duplicate content Using the same or thin page copy across multiple URLs confuses search engines about which version to rank. Each page needs unique content SEO that adds genuine value.

Four elements you must check on every page

  • Title tag Should include the primary keyword near the start and stay under 60 characters to avoid truncation in search results.
  • Meta description A 150–160 character snippet that summarises the page and entices clicks, even though Google may rewrite it. Write it for humans, but include the target phrase naturally.
  • Headings (H1, H2, etc.) Use a single H1 that matches the page topic, followed by logical subheadings to structure content for users and search engines.
  • Image alt text Describe the image accurately and naturally, including relevant keywords only when they fit the image context. This helps accessibility and gives search engines more context.

Three ways it affects your ranking

  • Relevance signals Search engines match page content, titles, and headings to user queries. Strong on-page SEO improves relevance and ranking potential.
  • Crawlability Clean code, descriptive URLs, and internal links help search engine bots discover and index your pages efficiently. This is a foundational step in the SEO process.
  • User experience A well-structured, scannable page with fast load times and clear navigation reduces bounce rates and signals quality to search engines.
