SEO today is far more than sprinkling keywords into a page. At Web Anatomy, we view SEO as a holistic ecosystem — a combination of strategies that together make your site discoverable, credible, and useful to both search engines and users.
To succeed in 2026 and beyond, you need to understand the full spectrum of SEO types and how they interact to drive sustainable growth. Below, we break down 15 essential SEO types, explain why they matter, and share actionable tips for each.
1. On-Page SEO – Optimising What Your Audience Sees
On-page SEO ensures that each page communicates its purpose clearly to both users and search engines.
Key elements:
- Page titles, meta descriptions, and headings that match search intent
- Well-structured, readable content
- Internal links that guide visitors and establish topical relationships
- Optimised images and multimedia with descriptive alt text
Why it matters: Proper on-page optimisation ensures relevance, improves user engagement, and signals to search engines that your content is authoritative.
Web Anatomy tip: Audit your most important pages to make sure headings, keywords, and content align with what people are actually searching for.
2. Technical SEO – Making Your Site Search-Engine Friendly
Technical SEO is the foundation of every strong SEO strategy. It ensures your site can be crawled, indexed, and interpreted correctly by search engines.
Focus areas:
- Site speed and Core Web Vitals
- Mobile-first, responsive design
- Secure HTTPS connections
- XML sitemaps, robots.txt, and canonical tags
- Structured data for content types (articles, products, events)
Why it matters: Even great content can’t rank if search engines can’t access it properly.
Web Anatomy tip: Use tools like Google Search Console to identify and fix crawl errors before scaling your content strategy.

Off-page SEO focuses on external signals that demonstrate your site’s credibility and authority.
Tactics include:

- Brand mentions in reputable media
- Partnerships and co-created content
- Social amplification to increase visibility
Why it matters: Search engines see off-page signals as votes of confidence in your content.
Web Anatomy tip: Focus on quality relationships, not just link volume — one authoritative backlink is more valuable than ten low-quality ones.

With most web traffic coming from mobile devices, Mobile SEO ensures a smooth experience for smaller screens.
