On-page SEO, at it’s most basic level, is the practice of optimizing your site’s pages and posts. That includes both content and under-the-hood code.
To get an idea of where your problem areas might be, ask yourself the following questions:
- Is your site mobile responsive?
- Have you done keyword research for all of your major pages?
- Do all of your images have targeted alt-tags?
- How long does it take your site to load?
