Migration and multisite – Advanced WordPress management

Two topics that scare beginner administrators: “How do I move a site without breaking anything?” and “What is this magical Multisite and do I need it?”. Let’s tackle them.

Part 1: WordPress migration

Moving a site (e.g., from local server to production or changing hosting) is a 3-step process:

1. Files: Copy everything from public_html (via FTP).
2. Database: Export the .sql file (e.g., through phpMyAdmin).
3. Domain Change (Key moment!): WordPress stores the site address in many places in the database (in wp_options, but also in post content as image links).

Amateur mistake: Manually editing the SQL file in notepad. This breaks “serialized data” (serialized arrays) of plugins and widgets. Professional method: Use WP-CLI (wp search-replace 'old.com' 'new.com') or Better Search Replace script. They maintain data integrity.

Part 2: Backups

The 3-2-1 rule:

• 3 copies of data.
• 2 different media (e.g., server + cloud).
• 1 copy off-site (outside the office).

Don’t rely solely on hosting. Install UpdraftPlus or Duplicator and send copies to Google Drive/Dropbox. It’s your insurance policy against hacker attacks or server room fires in Strasbourg (greetings to OVH).

Part 3: WordPress multisite

Multisite (MU) is a feature that allows running 100, 1000 or a million sites on one WordPress installation.

• One set of files (core, themes, plugins).
• One database (with separate tables for each site).
• One super-administrator.

When to use?

• You have a network of franchise sites (e.g., newyork.company.com, boston.company.com).
• You’re a university giving a blog to every student/professor.
• You run a multilingual service (though WPML/Polylang on a single installation often works better here).

When NOT to use?

• When you have 5 sites for completely different clients. If one site “dies” (PHP error), they all go down. Shared user database can also be problematic.

Multisite is a powerful tool, but requires a solid server and admin knowledge. Don’t enable it “for fun”.

Advanced Implementation Strategies

Successfully implementing these SEO techniques requires a systematic approach that balances technical optimization with content quality. Here’s how to execute each strategy effectively.

Technical Setup and Configuration

Begin by conducting a comprehensive audit of your current SEO setup. Use tools like Google Search Console, Screaming Frog, or SEMrush to identify existing issues and opportunities. Document your baseline metrics including current rankings, organic traffic, and conversion rates.

Content Optimization Workflow

1. Keyword Research Phase

   • Identify primary and secondary keywords
   • Analyze search intent for each term
   • Map keywords to existing content
   • Identify content gaps

2. Content Creation/Optimization

   • Write compelling titles and meta descriptions
   • Structure content with proper header hierarchy
   • Include relevant internal and external links
   • Optimize images with descriptive alt text

3. Technical Implementation

   • Ensure mobile responsiveness
   • Improve page load speed
   • Implement schema markup
   • Fix crawl errors

Measuring Success

Track these key performance indicators:

• Organic traffic growth
• Keyword ranking improvements
• Click-through rates (CTR)
• Conversion rates
• Bounce rates

Regular monitoring allows you to adjust your strategy based on what’s working and what’s not. SEO is an ongoing process, not a one-time task.
