Most new websites launch with zero visitors because SEO was overlooked from the start. This article provides 25 essential items to check before and after launching your website, ensuring Google discovers and ranks your site as quickly as possible. Divided into 3 phases: Pre-Launch, Launch Day, and Post-Launch.

Every page must have:
- 1.Title Tag - under 60 characters, includes primary keyword, unique per page

- 4.Heading Hierarchy (H2, H3) - H2 for main sections, H3 for subsections
