What is SEO and examples?
On-page and technical SEO
On-page SEO covers everything within your control on a given page: titles, meta descriptions, heading structure, and how naturally your target keywords appear in the body content. Underneath this sits technical SEO, and examples include page speed, mobile-friendliness, clean URL structures, and structured data (schema markup) that helps search engines and AI systems understand what a page is actually about.
Off-page SEO and content SEO
Off-page SEO is primarily about earning backlinks from other reputable websites — each one acts as a vote of confidence that search engines weigh when deciding how trustworthy your site is. Content SEO is the discipline of producing genuinely useful, well-researched material that satisfies what a searcher actually wants to know, rather than content written purely to contain keywords.
Four types of SEO and examples from a local bakery
Imagine a local bakery's website. On-page SEO means its product pages have clear titles like "Sourdough Loaf — Fresh Baked Daily, [Town]" rather than just "Product 12". Technical SEO means the site loads quickly on a phone. Off-page SEO means a local food blog links to them after a review. Content SEO means they've written a genuinely useful guide on "how to store sourdough bread" that answers a real question people search for.
How the four pillars work together
These four areas of SEO rarely operate in isolation — a page can have excellent content but still rank poorly if it loads slowly (technical) or has zero backlinks (off-page), and equally a technically flawless site with no useful content will struggle regardless of speed. Treating SEO as a single combined discipline, rather than four separate checklists, tends to produce more consistent results.
A second worked example: a local service business
Consider a plumbing company. Content SEO means writing a genuinely useful guide on "how to fix a dripping tap before calling a plumber" — content that satisfies a real search, even if it occasionally talks someone out of calling. On-page SEO means their "Emergency Plumber [Town]" page has that phrase naturally in the title and heading. Off-page SEO means they're listed and linked from local business directories. Technical SEO means the site doesn't time out when someone searches from their phone mid-emergency.
How AI search is changing what "SEO examples" look like
Traditional SEO examples focused almost entirely on ranking in a list of blue links. Increasingly, the same four pillars — on-page, technical, off-page and content — also need to support how AI-powered search summarises and cites sources directly. A well-optimised page today benefits not just from ranking well, but from being clearly structured enough that an AI assistant can confidently quote it as a source.
How to measure whether each pillar is actually working
On-page SEO can be checked by reviewing whether titles and headings genuinely match target search terms. Technical SEO is measured through page speed scores and crawl error reports. Off-page SEO is tracked through the number and quality of referring domains. Content SEO is best judged by engagement metrics like time on page and whether visitors take a meaningful next action.
Key Takeaways
- SEO covers four areas: on-page, technical, off-page and content.
- Each area reinforces the others — none works well in total isolation.
- A simple real-world example makes the four areas easier to recognise in practice.

Frequently asked questions
What are the four main types of SEO and examples of each?
SEO spans four areas. On-page SEO covers everything within your control on a page, including titles, meta descriptions, heading structure and natural keyword use. Technical SEO sits underneath, covering page speed, mobile-friendliness, clean URL structures and structured data. Off-page SEO is mainly about earning backlinks from reputable websites, each acting as a vote of confidence. Content SEO means producing genuinely useful, well-researched material that satisfies what a searcher wants to know. These areas rarely work in isolation, so treating SEO as one combined discipline tends to produce more consistent results than four separate checklists.
What is a simple real-world example of SEO?
Imagine a local bakery. On-page SEO means its product pages have clear titles such as a sourdough loaf, fresh baked daily, with the town name, rather than a label like Product 12. Technical SEO means the site loads quickly on a phone. Off-page SEO means a local food blog links to the bakery after writing a review. Content SEO means the bakery has written a genuinely useful guide on how to store sourdough bread, answering a real question people search for. Together, these four pillars help the right customers find the business.
How do you measure whether SEO is working?
Each pillar can be measured differently. On-page SEO can be checked by reviewing whether titles and headings genuinely match target search terms. Technical SEO is measured through page speed scores and crawl error reports. Off-page SEO is tracked through the number and quality of referring domains linking to the site. Content SEO is best judged by engagement metrics such as time on page and whether visitors take a meaningful next action. Because AI-powered search now summarises and cites sources, a well-optimised page should also be structured clearly enough for an AI assistant to quote.
