This guide organizes search engine optimization (SEO) into a study path from search fundamentals to implementation and evaluation. SEO improves a site’s eligibility to appear in relevant unpaid search results; it does not guarantee rankings.
Learning outcomes #
- Explain crawling, indexing and ranking.
- Research keywords by intent and audience need.
- Review on-page, technical and off-page SEO.
- Diagnose common indexability and usability issues.
- Use relevant metrics without confusing correlation with causation.
Core study areas #
- Search fundamentals: how search engines discover pages, process content and select results.
- Keyword research: search intent, topic coverage, long-tail queries and mapping pages to user needs.
- On-page SEO: useful content, descriptive titles, headings, internal links, image alternatives and readable URLs.
- Technical SEO: crawl access, indexation, canonicalization, XML sitemaps, robots directives, mobile usability and Core Web Vitals.
- Off-page SEO: earning relevant editorial links and building credibility without manipulative link schemes.
- Measurement: impressions, clicks, click-through rate, landing-page outcomes and query/page trends.
Practical audit checklist #
- Confirm the page answers a clear search intent and adds original value.
- Check that important pages are internally linked and can be crawled.
- Review title, main heading, content structure and descriptive image text.
- Check canonical tags, redirects, broken links and duplicate or thin pages.
- Inspect mobile experience and page performance.
- Compare Search Console trends over an appropriate period and annotate site changes.
Practice exercise #
Choose one page and create a table with target audience, likely intent, primary topic, supporting questions, internal links, technical checks and a measurable outcome. Prioritize fixes by expected impact, confidence and effort rather than changing every element at once.

Be ready to explain the difference between crawling and indexing, how intent affects page selection, why canonical tags matter, and why rankings alone are not a complete measure of SEO success.
