# The Ultimate On-Page SEO Checklist
On-page SEO is the foundation of search visibility. Here is everything you need to optimize.
## Title Tags
Keep under 60 characters, include primary keyword near the beginning, and make it compelling.
## Meta Descriptions
Write unique descriptions for every page, 120-155 characters, with a clear call to action.
## Header Structure
Use a single H1 per page, organize with H2s and H3s, and include keywords naturally.
## Content Quality
Follow E-E-A-T: experience, expertise, authoritativeness, and trustworthiness.
## Image Optimization
Compress images, use descriptive file names, always include alt text, and implement lazy loading.
