What Is On-Page SEO?

On-page SEO refers to everything you can control directly on your website—like page titles, headings, content structure, and image alt text—to help search engines understand what your page is about.

Think of it as labeling each section of a physical store so customers (and search engines) can find exactly what they need without confusion.

Focus on Page Titles First

Your page title is the first thing search engines and users see. It should be clear, concise, and include your main keyword.

For example:

  • Bad: My Blog Post About Cooking
  • Good: Easy Vegan Pasta Recipe | Healthy Dinner Ideas

Use Headings to Structure Content

Headings (H1, H2, H3) help both readers and search engines navigate your content. Use them like a table of contents.

Aim for one main heading per page (the H1), then break down supporting topics into H2s and H3s as needed.

Optimize Image Alt Text

Alt text describes images for search engines and screen readers. Don’t skip it—it’s a small effort with big SEO benefits.

Instead of:

  • Bad: image123.jpg
  • Good: vegan pasta dinner on wooden table

Your Checklist for On-Page SEO

  • Write a unique title tag for each page with your main keyword
  • Use one H1 per page, followed by clear H2s and H3s
  • Include alt text on all images describing the content
  • Add internal links to related pages within your site

Taking It Further: Tools That Help

For Mac users, tools like Google Search Console and Screaming Frog SEO Spider (available on macOS) can help identify issues without overwhelming you.

Start small. Pick one or two items from your checklist each week.
