Legacy URL Suffix & SEO Preserver

Description

Don’t Let Your SEO Rank Vanish During a Migration.

Migrating a legacy website to WordPress is a massive win for your workflow, but it can be a disaster for your search engine rankings. If your old site used .php extensions (e.g., domain.com/about-us.php), moving to standard WordPress « Clean Permalinks » will turn every one of those established links into a 404 Page Not Found error.

PHP to Pages is the lightweight, « set it and forget it » solution that bridges the gap between your legacy architecture and modern WordPress flexibility.

The Value Proposition

« Seamlessly transition from legacy PHP sites to WordPress while maintaining 100% URL consistency. No complex .htaccess coding, no broken backlinks, and zero SEO drop-off. »

Why Choose PHP to Pages?

When you change your URL structure, you lose the « link juice » accumulated over years. This plugin ensures that your existing backlinks from social media, external blogs, and Google search results remain active and functional.

  • Instantly Append .php Suffix: Automatically transforms yoursite.com/sample-page/ into yoursite.com/sample-page.php.
  • SEO Preservation: Keep your indexed URLs exactly as they appear in Google Search Console to avoid the dreaded « re-indexing » phase.
  • Zero-Configuration Setup: No need to dive into your server’s .htaccess or Nginx config files. Just activate and your permalinks update instantly.
  • Developer Friendly: Built with standard WordPress Rewrites API, ensuring compatibility with most well-coded themes and plugins.
  • Lightweight Performance: No bloat, no database-heavy queries. It simply tells WordPress how to read and display your URLs.

Who Is This For?

  • Agencies & Freelancers: Moving a long-term client from a static PHP site to WordPress.
  • SEO Specialists: Ensuring that a site migration doesn’t result in a loss of organic traffic.
  • Legacy Site Owners: Anyone who has a decade’s worth of backlinks pointing to .php files and doesn’t want to manage thousands of manual 301 redirects.

How It Works

  1. Install & Activate: Simply upload the plugin to your WordPress dashboard.
  2. Permalinks Refresh: Go to Settings > Permalinks and click « Save Changes » to flush your rewrite rules.
  3. Done: Your pages will now resolve with the .php extension.
