The Playful Sparkle – Google Sitemap extension for OpenCart 3.x+, 4.x+ offers a refined XML sitemap generation solution that aligns with search engine standards and SEO best practices. This extension supports detailed customization, allowing OpenCart merchants to tailor sitemaps to include specific product pages (with images), category pages (with images), and manufacturer pages, all tagged to support complete, accurate indexing by search engines.

A key feature of the extension is its use of PHP’s XMLWriter class to generate standards-compliant XML sitemaps per the Sitemaps.org protocol. This ensures that search engines can efficiently crawl site content, aided by the <lastmod> attribute included on product and category pages. The <lastmod> attribute, which tracks the date of the most recent content update, allows search engines to prioritize updated pages, increasing the likelihood of timely indexing.

To streamline sitemap accessibility, the extension can automatically update the .htaccess file, enabling users and Google Search Console to access sitemaps using clean, SEO-friendly URLs like /en-gb/sitemap.xml instead of the default OpenCart URL format, such as index.php?route=extension/feed/ps_google_sitemap&language=en-gb. This improvement ensures compatibility with Google Search Console requirements and simplifies sitemap management.
