Doing effective on-page SEO starts with keyword research to understand what terms your target audience uses. Craft compelling, keyword-rich title tags (under 60 characters) and meta descriptions (under 160 characters) that encourage clicks from search results. Structure your content with a single H1 tag containing your primary keyword, then use H2 and H3 subheadings to organise information logically. Write comprehensive, valuable content that thoroughly addresses user intent, incorporating keywords naturally without stuffing. Optimise images with descriptive file names and alt text, ensure fast page loading speeds, and create clean, descriptive URLs. Add internal links to relevant pages on your site, implement structured data markup where appropriate, and ensure your page is mobile-friendly.
