Facebook for WooCommerce is Meta’s official integration plugin for WooCommerce stores. In WordPress, you’ll usually see it as “Facebook for WooCommerce” (sometimes branded as Meta). It links your store with Meta Business tools so you can sync products to a Facebook/Instagram catalog, set up tracking, and run ads. It’s designed for WooCommerce stores, not just normal WordPress pages. After installing, the plugin walks you through connecting your Business Manager, Facebook Page, ad account, and Commerce catalog, then it starts product sync and tracking setup. You’ll need admin access to the Page and Business Manager, plus a verified domain for best results.

If you mean an alternative to selling through Facebook for WooCommerce, the best options are other sales channels and ad platforms. For social selling, try Instagram Shopping, TikTok Shop, Pinterest Shopping, and Google Merchant Center for free listings. For marketplaces, use Amazon, eBay, Etsy, Walmart Marketplace, or Flipkart, depending on your niche. For advertising, Google Search and Shopping ads often convert well for buyer intent, and YouTube can drive demand. For direct communication, build email marketing with Klaviyo or Mailchimp, plus WhatsApp Business for follow-ups. Also invest in SEO and content so you own long-term traffic.

Variants in WooCommerce are called product variations. They are different versions of one variable product, based on attributes like size, color, material, or style. For example, one “T-Shirt” product can have variations like Small/Blue, Medium/Blue, Large/Black, and so on. Each variation can have its own SKU, price, stock quantity, image, weight, and shipping class. Customers choose attribute options on the product page, and WooCommerce selects the matching variation to add to cart. Variations help keep your catalog cleaner because you don’t need separate products for every option combination.

You can create more than 50 variations, but WooCommerce loads them in batches in the admin. Go to the variable product → Variations, and use “Generate variations” from attributes to create many at once. Use “Bulk actions” to set prices, stock status, or shipping settings across all variations. If the variation list stops loading, increase PHP memory limit, max execution time, and upload limits on your server. Disable heavy plugins while generating variations, and clear object cache if it becomes stuck. For very large variation sets, import variations via CSV, or use a product import plugin, then optimize database and hosting.

WooCommerce does not set a strict fixed limit on variations, but performance becomes the real limit. Many stores work fine with a few hundred variations per product. When you reach thousands, the product edit screen, imports, and checkout can slow down. The practical maximum depends on hosting resources, database size, caching, and how many attributes you load on the product page. Variable products also increase admin load because each variation stores price, stock, image, and shipping data. For large catalogs, consider splitting products, using fewer attributes, or using plugins that handle variations more efficiently.

If the WooCommerce add to cart button is missing, first confirm the product is purchasable. Check product type, price, stock status, and catalog visibility. If it is external or grouped, the button may differ. Switch to a default theme temporarily to rule out theme conflicts. Disable plugins one by one to find conflicts, especially custom cart, caching, or page builder plugins. Verify WooCommerce templates were not overridden incorrectly in your theme. Re-save permalinks and clear all caches. Ensure you did not enable “Catalog mode” or hide prices. Check custom code removing hooks like woocommerce_after_shop_loop_item. Finally, update WooCommerce, theme, and PHP version for compatibility.

To make the cart link update via Ajax, ensure WooCommerce cart fragments are enabled. Most themes load wc-cart-fragments automatically. If your cart count or mini cart does not update, check that caching/minification plugins are not delaying or removing cart fragment scripts. Exclude wc-ajax=get_refreshed_fragments and the cart/checkout pages from cache. If you want a dynamic cart count in the header, add a cart icon with a span for count and update it using WooCommerce fragments or a small custom script that listens to added_to_cart events. Many header builder plugins also provide an Ajax cart
