How to do on-page SEO step by step

Start with keyword research to identify the primary keyword and 2-3 related secondary keywords you want to rank for on that specific page. You're looking for terms with actual search volume and reasonable competition for your client's situation. Once you've selected your primary keyword, incorporate it naturally into your page title (keep it under 60 characters), making sure the keyword appears near the beginning. The title should actually entice clicks—it's not just for search engines. Your meta description should be 155-160 characters and include the primary keyword while clearly describing what visitors will find on the page. This description appears in search results and significantly impacts click-through rates, so write it as you would marketing copy.

On the page itself, use your primary keyword in the H1 tag (you should have exactly one H1 per page), then structure the content with secondary keywords distributed across H2 and H3 subheadings. This creates a logical hierarchy that helps both search engines and readers understand your content. Write substantive content—at least 800-1,200 words for competitive topics—that comprehensively answers the search intent behind your target keyword. Don't stuff keywords; instead, write naturally and let them appear where they make sense. If your keyword is "commercial HVAC repair," you'd naturally use it a few times throughout, plus variations like "commercial air conditioning maintenance" and "HVAC system repairs for businesses."

Include 2-4 internal links pointing to other relevant pages on your site using descriptive anchor text (not "click here"). This distributes page authority and helps search engines understand your site structure. For external links, cite reputable sources when relevant—this builds credibility and shows you're providing well-researched information. Make sure your page loads quickly (under 3 seconds), is mobile-responsive, and has a clear user experience. Add an image or two related to your content, optimize the image file size, and use descriptive alt text with your keyword naturally incorporated. Finally, ensure the URL is clean and descriptive (like example.com/commercial-hvac-repair) rather than something with random numbers or parameters. These steps form the foundation of solid on-page optimization that actually impacts rankings.
