Search engine optimization (SEO) is the practice of improving a website so search engines can discover, understand, and present its pages to people looking for relevant information. Strong SEO combines technical accessibility, useful content, clear site architecture, and a good user experience.
1. Start with search intent
Before drafting a page, identify what the searcher is trying to accomplish. A query may signal that someone wants to learn, compare options, complete a task, or reach a specific destination. The page format should match that need.
- Informational intent: explain a topic or answer a question.
- Commercial investigation: help readers compare approaches or products fairly.
- Transactional intent: make the next step clear and easy.
- Navigational intent: help people reach a known brand or resource.
2. Keep the technical foundation healthy
Search engines need to access pages and interpret their content. Check that important URLs return successful responses, internal links work, pages are not accidentally blocked, and canonical tags point to the preferred URL. Use descriptive titles, meaningful headings, and a mobile-friendly layout.
For a static GitHub Pages site, also verify that the repository publishes the correct branch and folder, asset paths work on nested pages, and your sitemap lists only live canonical URLs.
3. Publish genuinely helpful content
Build each page around a clear audience need. Answer the main question early, use headings that describe what follows, provide examples, cite reliable sources when making factual claims, and update content when it becomes outdated. Avoid writing multiple near-identical pages just to target tiny keyword variations.
Make every page easy to scan
- Use one clear page title and a logical heading hierarchy.
- Write short paragraphs and define specialist terms.
- Use tables or lists when they genuinely improve comprehension.
- Link to related pages with descriptive anchor text.
- Include original experience, analysis, or useful detail where possible.
4. Improve on-page signals
Write unique title tags that accurately describe each page. Meta descriptions should summarize the page and give searchers a reason to click, but they are not a direct ranking guarantee. Use descriptive image alt text when an image communicates information; decorative imagery should not receive keyword-stuffed alt text.
5. Measure outcomes, not just rankings
Track relevant impressions, clicks, organic landing pages, conversions, and engagement against a baseline. Use the data to find pages that deserve better coverage, titles that do not communicate value, or technical issues that block discovery. Rankings fluctuate, so avoid making major decisions based on a single day of data.
A practical SEO checklist
- Important pages can be crawled and indexed where intended.
- Each page has a distinct purpose and descriptive title.
- Content answers the searcher's actual question.
- Internal links connect related resources.
- Pages load well and work on mobile screens.
- Broken links, redirects, and canonical URLs are checked.
- Performance is reviewed with consistent metrics.
How SEO connects with AEO and GEO
SEO remains a useful foundation for discovery, but audiences increasingly encounter information through answer engines and generative experiences. Clear structure, accessible pages, reliable sourcing, and helpful content support all three disciplines. The tactics differ by platform, so measure results and avoid assuming one optimization guarantees visibility everywhere.
