OpenCart Canonical Link + Domain Selector

Problem Statement:

OpenCart's default system does not include proper canonical URLs, which can lead to duplicate content issues, negatively affecting SEO rankings. Additionally, multi-store setups often require a single canonical domain across all stores, which OpenCart does not natively support.

Purpose of the Extension:

This extension is designed to give OpenCart store owners full control over their canonical URLs, ensuring the correct domain and URL version is indexed by search engines. It is particularly beneficial for multi-store OpenCart users who need to enforce a primary domain across multiple stores to maintain SEO integrity.

Features:

• Set canonical URLs for product, category, manufacturer, and information pages.
• Customize the canonical domain for multi-store setups.
• Prevent duplicate content issues by defining a preferred version of a page.
• Supports multi-language stores by ensuring the correct language-specific canonical links.
• Works seamlessly with SEO-friendly URLs to maintain clean and optimized links.
• Simple and easy-to-use admin settings to control canonical links effectively.
• Fully compatible with OpenCart's multi-store feature, allowing different domain preferences.
• Improves SEO rankings by providing a clear structure for search engines.
• Lightweight and optimized for performance with minimal impact on page load speed.
• No core file modifications required – uses OCMOD for safe integration.

How to Use:

1. Install the extension using the OpenCart extension installer.
2. Enable and configure the settings from the admin panel.
3. For multi-store setups:
   • Go to the Product Edit Page in the admin panel.
   • Enter your preferred canonical domain in the provided field.
   • Save changes, and the canonical URL will be updated accordingly.
4. The canonical links will now reflect the specified domain across all stores.

Benefits:

• Eliminates duplicate content penalties in search engines.
• Improves search ranking by defining the correct canonical page.
• Provides flexibility for multi-store users by setting a preferred canonical domain.
• Enhances user experience by directing visitors to the most relevant version of a page.
• Easy to manage with a simple admin interface.

Use Cases:

• Single Store Users: Define canonical URLs for SEO improvement.
• Multi-Store Users: Ensure a single domain version of pages across multiple stores.
• SEO Agencies & Developers: Optimize OpenCart stores for better search visibility.

Expected Results:

• Increased SEO performance by avoiding duplicate content penalties.
• Proper indexing of preferred URLs by search engines.
• Better traffic distribution by consolidating link authority to the preferred domain.
