Follow this checklist to migrate your website to a new platform or domain. Brought to you by MangoBlogger.com
For 2026 standards—especially for a modern web project—we need to group these into logical phases (Infrastructure, SEO, Marketing, and UX) and add missing technical requirements like Performance (Core Web Vitals) and Security.
And you also need the essential HTML tags - http://prasannakulkarni.com/essential-html-tags-for-seo/
1. Infrastructure & Security
- Git Management: Ensure
.gitignoreis properly configured (excludenode_modules,.env, and OS-specific files likeThumbs.db). - SSL/HTTPS: * Automatic HTTP to HTTPS redirection (HSTS enabled).
-
Verification of "Green Padlock" on all subdomains.
-
Canonical Redirects: * Strictly enforce WWW vs. Non-WWW. Pick one and 301 redirect the other to prevent duplicate content issues.
- Favicon Suite: Don't just have one
.icofile. Ensure you have high-res versions for Apple Touch Icons and Android Chrome (Manifest.json).
2. Technical SEO & Structure
- Robots & Sitemaps: *
robots.txtpoints to thesitemap.xmlURL. -
Dynamic sitemap that updates when new pages are published.
-
Breadcrumb Schema: (Updated from your snippet) Ensure the JSON-LD is dynamic and reflects the current page hierarchy.
- Schema Markup (JSON-LD): * Organization: Logo, social links, and contact info.
- Local Business: (If applicable) Address and Geo-coordinates.
-
Product/Service: Review stars and pricing if relevant.
-
Open Graph (OG) & Twitter Cards: * Set a default "Fall-back" image for social shares.
- Validate via LinkedIn Post Inspector or Facebook Sharing Debugger.
3. Performance & Core Web Vitals (The "2025 Upgrade")
- Image Optimization:
- Images are in modern formats (WebP or AVIF).
widthandheightattributes set on all images to prevent "Layout Shift" (CLS).-
Lazy loading enabled for off-screen images.
-
Caching & Minification: * Minify CSS, JS, and HTML.
-
Configure browser caching headers for static assets.
-
Page Speed: Aim for a "Green" score (90+) on Google PageSpeed Insights.
4. Tracking & Analytics
- Google Tag Manager (GTM):
- Container snippet placed correctly (Head and Body).
-
Preview mode tested to ensure tags fire on click/submit.
-
GA4: Enhanced measurement turned on (scrolling, outbound clicks, site search).
- Conversion Tracking: * Facebook (Meta) Pixel with Conversion API (CAPI) for better data accuracy.
- Google Ads conversion tags for "Lead Magnet" downloads or "Thank You" page hits.
5. Conversion & UX
- Lead Magnet: * Form validation (ensures email format is correct).
- Automated "Thank You" email or redirect.
-
Privacy Policy link visible near the sign-up button (GDPR/CCPA compliance).
-
404 Page: Custom 404 page with a "Return to Home" button or search bar.
- Accessibility: Ensure a minimum color contrast ratio and
alttext for all images.
💡 Pro-Tip: Breadcrumb Validation
Your JSON-LD snippet looks good, but make sure the position index starts at 1 and includes the Home page if that is part of your site structure. For example:
{
"@context": "https://schema.org",
"@type": "BreadcrumbList",
"itemListElement": [{
"@type": "ListItem",
"position": 1,
"name": "Home",
"item": "https://www.sunbeamlenopack.com/"
},
{
"@type": "ListItem",
"position": 2,
"name": "Industrial Packaging",
"item": "https://www.sunbeamlenopack.com/industrial-packaging"
}]
}
