3. On-Page SEO (Type 1)
What Is On-Page SEO?
On-page SEO refers to optimising the content and HTML elements on your website to help search engines understand the content of your pages. This is where you have direct control.

What Is Off-Page SEO?
Off-page SEO is all about strengthening your website’s authority outside your website. It includes activities that show Google your brand is credible and trustworthy.
Why Off-Page SEO Matters
Google uses external signals—especially backlinks—to determine if your content deserves to rank. The stronger your backlink profile, the stronger your domain authority becomes.
Effective Off-Page SEO Techniques
Here are essential off-page SEO techniques:
- Backlink strategies (guest blogs, niche edits, resource links)
