A Beginner’s Guide to On-Page SEO in 2025
Share
Search Engine Optimisation (SEO) is always evolving—but one thing that never changes is the importance of on-page SEO. In 2025, Google continues to reward websites that provide a seamless user experience, valuable content, and clear relevance.
If you’re just getting started, this guide will walk you through the fundamentals of on-page SEO and how to optimise your website for success.
What Is On-Page SEO?
On-page SEO refers to the practice of optimising individual web pages to improve their search engine rankings. Unlike off-page SEO (like backlinks), on-page SEO is everything you can control directly on your website—from your content to your technical setup.
Key On-Page SEO Elements in 2025
1. Title Tags
Your title tag is the first thing people see in search results. Keep it under 60 characters, include your primary keyword, and make it compelling enough to encourage clicks.

2. Meta Descriptions
Meta descriptions don’t directly affect rankings, but they drive click-through rates (CTR). Aim for 150–160 characters, summarise your page, and include a call-to-action.
3. Headings (H1, H2, H3)
Use headings to structure your content. Your H1 should include your main keyword, while H2s and H3s can organise subtopics. This helps both readers and search engines understand your content.
4. Content Optimisation
High-quality, relevant content is the backbone of SEO in 2025. Focus on:
-
Search intent – Answer what the user is actually looking for.
-
Keyword placement – Use your target keyword naturally in the first 100 words, headings, and throughout the text.
-
Depth & clarity – Cover the topic thoroughly, but make it easy to read.
5. URL Structure
Clean, descriptive URLs perform better. Keep them short, include keywords, and avoid unnecessary numbers or symbols.

6. Internal Linking
Link to other relevant pages on your site to help users and search engines discover your content. Aim for natural anchor text rather than stuffing keywords.
7. Image Optimisation
Images should enhance your content—not slow it down. In 2025:
-
Use compressed images for faster loading.
-
Add alt text with descriptive keywords for accessibility and rankings.
-
Consider webp format for better performance.
8. Mobile-Friendliness
With mobile-first indexing, your site must be fully responsive. Test your site on different devices to ensure a smooth user experience.
9. Page Speed
Google prioritises sites that load quickly. Use tools like Google PageSpeed Insights to check performance and reduce load times.
10. Schema Markup
Structured data (schema) helps search engines understand your content. Adding schema can also get you rich snippets (stars, FAQs, pricing) that increase visibility in search results.
