What Is On-Page SEO?
On-page SEO (sometimes called on-site SEO) is the process of optimising individual web pages so they can rank higher in search engines like Google.
That means:
- Using the right keywords in the right places
- Writing useful, relevant content
- Creating a great user experience (fast, readable, mobile-friendly)
It’s one part of the SEO puzzle, alongside off-page SEO (like backlinks) and technical SEO (like site structure and crawlability).
Main Elements of On-Page SEO
1. Page Title (Meta Title)
This is what shows up in Google results and the browser tab.
Best practices:
- Include your target keyword
- Keep it under 60 characters
- Make it click-worthy (add benefits or emotion)
Example:
“Massage Therapy in Leeds | Book a Relaxing Treatment Today”
2. Meta Description
This is the short description under the title in Google search results.
- Include the keyword naturally
- Keep it under 160 characters
- Use a call to action (e.g. “Book online”, “Find out more”)
3. Headings (H1, H2, H3…)
Headings break up your content and help Google understand the page structure.
- Only one H1 (this is usually your page title)
- Use H2s for sections, H3s for subsections
- Include keywords in headings where it makes sense
4. URL Structure
The page URL should be short, clean, and descriptive.
Example: /on-page-seo
is better than /page?id=12345
- Use hyphens (not underscores)
- Include the target keyword
5. Keyword Placement
Use the keywords naturally throughout your page.
Include keywords in:
- Page title (H1)
- First paragraph
- Subheadings
- Image alt text
- Meta description
- Page URL
6. Content Quality & Relevance
Google wants to show pages that truly help the searcher.
- Write for humans, not algorithms
- Be useful and easy to read
- Match the search intent
Bonus tips:
- Use short paragraphs
- Include examples and visuals
- Cover the topic in depth
7. Internal Linking
Linking between your own pages helps Google understand your site and keeps visitors engaged.
Tips:
- Use descriptive anchor text (not just “click here”)
- Link to both pages and blog posts
8. Images & Alt Text
Images should support your content, not slow it down.
- Compress images to improve speed
- Use relevant file names (e.g.
massage-leeds.jpg
) - Add alt text to describe the image
9. Mobile-Friendliness
More than 60% of users browse on mobile. Google now ranks mobile versions first.
- Use a responsive design (most WordPress themes are)
- Test your site on mobile regularly
- Avoid pop-ups that block content
10. Page Speed
Fast pages = better rankings + better user experience.
Tools to test speed:
- Google PageSpeed Insights
- GTmetrix
- Pingdom Tools
Quick wins:
- Compress images
- Minimise plugins
- Use a caching plugin
