How to do on page SEO in WordPress

On-page SEO in WordPress starts with your content structure and technical foundation. Install Yoast SEO or Rank Math to handle the mechanics—these plugins give you real-time feedback on keyword optimization, readability, and meta descriptions. More importantly, they force you to think through your target keyword upfront rather than optimizing randomly. Set your focus keyword before writing, and the plugin will guide you on keyword density, placement in headings and the first 100 words, and internal linking suggestions. This removes guesswork for you and your clients.

Beyond the plugin, pay attention to what WordPress handles automatically. Your permalink structure matters—use the post name option (domain.com/post-title/) rather than default numbers. Make sure your site uses HTTPS and has a solid Core Web Vitals score; WordPress plugins can tank performance, so audit them ruthlessly. Image optimization is where many agencies leave money on the table. Compress images before uploading (use TinyPNG or similar), use descriptive filenames and alt text, and let WordPress generate responsive sizes automatically. The alt text is crucial for both accessibility and SEO—describe what's actually in the image, naturally including your keyword when it makes sense.

On-page structure matters for both users and search engines. Use heading hierarchy properly: one H1 per page (usually your title), then H2s and H3s for subsections. This creates the logical structure Google's crawlers expect. Internal linking is where WordPress really shines—you can strategically link to pillar content or related posts with keyword-rich anchor text. Don't overdo it, but if you're writing about "WordPress SEO," link to your comprehensive guide on WordPress optimization when relevant.

Finally, don't neglect the basics that WordPress makes easy to overlook. Write unique, compelling meta descriptions under 160 characters for each page. Set a reading time estimate—it increases engagement signals. Use categories and tags thoughtfully, but don't go overboard; your navigation should be clear for both users and crawlers. Most agencies and freelancers already have Yoast installed, but they're not leveraging the site structure analysis or internal linking recommendations it provides. That's where you'll find quick wins for your clients' rankings.
