Product XML Sitemap

When the product sitemap is enabled, the plugin serves its own set of XML sitemaps through rewrite rules, separate from any sitemap an SEO plugin generates. The sitemaps are built for large catalogs, with pagination, caching, batching, and memory guards.

Sitemap URLs

URL	Contents
/wog-sitemap.xml	Sitemap index that links to the others
/product-sitemap-1.xml (and -2, -3, …)	Products, paginated
/product-category-sitemap.xml	Product categories
/product-brand-sitemap.xml	Product brands, when a brand taxonomy exists

The index lists one product sitemap page per block of products, plus the category and brand sitemaps when they have content.

What is included

• Products: published, non-hidden products (products excluded from catalog or search are left out). Each entry has the URL, last-modified date, change frequency, priority, and the featured image.
• Categories: non-empty product categories, with last-modified date, change frequency, priority, and the category image when set.
• Brands: read from the first available brand taxonomy among product_brand, pwb-brand, yith_product_brand, and pa_brand.

Change frequency and priority are calculated per item (for example, featured, on-sale, in-stock, well-reviewed, and highly rated products get a higher priority).

Products per sitemap page

The number of products per sitemap page is set by the Products Per Sitemap option (default 500, allowed range 100 to 1000).

Generation and caching

• Sitemap output is cached for one hour per page in transients.
• A daily background event, wog_generate_sitemaps, regenerates all sitemaps.
• Saving or updating a product or product category schedules a regeneration about ten minutes later.
• From the settings page you can trigger an immediate regeneration or test the sitemap. See Settings Reference.

robots.txt

When the sitemap is enabled, the index URL is added to the site’s robots.txt output so search engines can discover it.
