On-page SEO refers to all the optimisations you make directly on your website to help it rank higher in search results. Unlike off-page SEO — which involves earning backlinks from other sites — on-page SEO is entirely within your control. This guide covers everything you need to know.
Title Tags
Your title tag is the most important on-page SEO element. It appears as the clickable headline in search results and should include your primary keyword near the beginning. Keep it between 50–60 characters to avoid being truncated.
Header Tags (H1, H2, H3)
Use one H1 tag per page — this should be your main page title. Use H2 and H3 tags to structure your content into logical sections. Include relevant keywords in your headers naturally to help search engines understand your content structure.
Content Quality and Length
Google rewards comprehensive content that thoroughly answers a searcher’s query. Aim for content that covers a topic in-depth rather than thin pages with minimal information. Use related keywords, synonyms, and semantic phrases throughout your content.
Internal Linking
Link to other relevant pages on your website using descriptive anchor text. Internal links help search engines discover and index your pages, spread authority across your site, and keep visitors engaged with more of your content.
Image Optimisation
Always add descriptive alt text to your images. This helps visually impaired users understand your content and gives search engines additional context about what your page covers.
