SOP: New Site Launch SEO Checklist

1. Overview

Launching a new website without a structured checklist is a primary cause of organic visibility failure. The technical decisions made in the first 30 days determine how quickly search engines discover, crawl, and index content.

This SOP sequences critical tasks across three phases: Pre-Launch (Foundation), Launch Day (Execution), and Post-Launch (Validation).

Epistemic Marker — Heuristic: Timelines below are standard for mid-sized sites. Complex enterprise migrations may require extended lead times.

2. Phase 1: Pre-Launch (2–4 Weeks Before Go-Live)

The Pre-Launch phase establishes the technical and strategic foundation. Errors here compound after launch.

2.1 Technical Infrastructure

Reference: Crawlability & Indexation
The pipeline is Crawl → Render → Index. Ensure bots can access the site.

• [ ] Clean Domain: Verify the domain has no spam history (use Ahrefs/Google Transparency Report).
• [ ] Enforce HTTPS: Ensure valid SSL and force 301 redirects from HTTP to HTTPS.
• [ ] Robots.txt: Allow crawling of public content. Note: Disallow does NOT prevent indexing; use noindex tags for that.
• [ ] XML Sitemap: Generate a clean sitemap excluding noindex, redirects, and 404s.
• [ ] Canonical Tags: Ensure every page has a self-referencing rel="canonical" tag. (Ref: Site Migrations)

Reference: Page Speed & Core Web Vitals
Performance must be built-in, not retrofitted.

• [ ] Metrics: Target LCP < 2.5s, INP < 200ms, CLS < 0.1.
• [ ] Optimization: Compress images (WebP/AVIF), defer non-critical JS, and utilize a CDN.

2.2 Site Architecture & Content

Reference: Internal Linking & Keyword Research
Define the structure before writing content.

• [ ] Pillar-Cluster Map: Ensure pillars link to clusters, and clusters link back.
• [ ] Click Depth: Key pages must be within 3 clicks of the homepage.
• [ ] Intent Mapping: Assign every keyword an intent type (Info/Comm/Trans) and target URL.
• [ ] URL Hygiene: Use lowercase, hyphen-separated, descriptive URLs. No parameters.

2.3 On-Page & Data

Reference: Title Tags & Schema
Metadata is the first interaction with both users and AI agents.

• [ ] Title Tags: Front-load keywords, < 60 chars, 100% unique.
• [ ] Meta Descriptions: Active voice, implied CTA, < 160 chars.
• [ ] Structured Data: Implement JSON-LD for Organization, WebSite, and Article/Product.

2.4 Staging Audit (Crucial)

Crawl the staging site to verify:
– [ ] No broken internal links (404s).
– [ ] No redirect chains > 2 hops.
– [ ] Critical: Verify noindex tags are present on Staging but planned for removal on Production.

3. Phase 2: Launch Day Execution

Launch day is for execution, not experimentation. Verify these within 24 hours of go-live.

4. Phase 3: Post-Launch Monitoring (Days 1–90)

Transition from setup to validation.

4.1 Week 1: Crawl Validation

• Monitor GSC: Check “Pages” report for “Discovered – currently not indexed” spikes.
• Server Logs: Verify Googlebot is actively requesting pages.
• Fix 404s: Resolve any broken links immediately.

4.2 Weeks 2–4: Baselines

• Keyword Impressions: Monitor GSC Performance. Rankings will fluctuate (Sandbox effect).
• CWV Field Data: Check GSC Core Web Vitals report once data populates.
• Orphan Check: Re-crawl to ensure no pages were orphaned during launch.

4.3 Days 30–90: Growth

• Publishing: Begin regular cluster content updates to signal freshness.
• Link Building: Initiate digital PR or outreach to build initial domain authority.
• CTR Optimization: Refine titles/metas for high-impression/low-click pages.

5. Common Launch Failures

6. Key Takeaways

1. The Launch is a System: It is not a single event but a cycle spanning Pre-Launch preparation, Launch Day execution, and 90 days of Post-Launch monitoring.
2. Technical Access is Foundational: If search engines cannot crawl, render, and index the site (Rule 2.1), no amount of content or link building will produce results.
3. Architecture Before Content: Define the pillar-cluster structure and keyword-intent map before writing a single page to avoid costly restructuring later.
4. Data Integrity: Ensure analytics and tracking are verified immediately upon launch to establish a reliable performance baseline.
