WooCommerce is a company behind the WooCommerce eCommerce platform, best known for its WordPress plugin that helps businesses sell online. It builds and maintains WooCommerce core, plus related tools like WooCommerce Payments, extensions, and support resources. WooCommerce focuses on open-source commerce, giving store owners flexibility and control while using WordPress. The brand is part of the broader WordPress ecosystem and works closely with hosting partners, developers, and merchants to power online stores worldwide.

The best size for a product image depends on your website layout, but common recommendations work well for most stores. For WooCommerce, a product image size of 800 × 800 pixels is ideal. This size keeps images sharp on desktop and mobile screens. Square images work best for consistent layouts and clean grids. Images should be high quality but not too heavy. A file size under 200 KB is recommended for faster loading. Use JPG format for photos and PNG for images needing transparency. Always use the same image size for all products.

To integrate FedEx with WooCommerce, create a FedEx account and request API/Web Services credentials (account, meter, key, password). In WordPress, install a FedEx shipping plugin for WooCommerce (official extension or an alternative). Go to WooCommerce → Settings → Shipping, add a Shipping Zone, then add the FedEx shipping method. Paste credentials, choose allowed services (Ground, 2Day, Overnight), set origin address, packaging type, and handling fees. Enable live rates at checkout and decide whether to show delivery estimates. Test with sandbox or low-value orders. Finally, ensure product weights/dimensions are filled, and configure label printing and pickup if your plugin supports it.

WooCommerce supports Ajax add to cart on archive pages by default. Go to WooCommerce → Settings → Products and enable “Redirect to the cart page after successful addition” OFF. Then enable “Enable AJAX add to cart buttons on archives” ON. Your theme must support it, so use a WooCommerce-ready theme and avoid disabling WooCommerce scripts. For single product pages, Ajax is not default for variable products. Use a plugin like “WooCommerce Ajax Add To Cart” or a custom script to submit the form via Ajax. Finally, test cart updates, mini cart refresh, and caching exclusions.

To add a product category filter in WooCommerce, you can use built-in widgets or blocks. Go to Appearance → Widgets or Appearance → Editor, depending on your theme. Add the Product Categories widget or block to your shop sidebar or filter area. Choose display options like dropdown or list, and save changes. For block-based themes, you can also use the Filter by Category block on shop pages. If you need advanced filters, install a product filter plugin. These plugins add AJAX filters, checkboxes, and mobile-friendly layouts without reloading pages.

To keep WooCommerce emails out of spam, send mail through authenticated domains. Set up SPF and DKIM records, and add DMARC with a monitoring policy. Use a dedicated SMTP provider (SendGrid, Mailgun, Amazon SES, etc.) instead of PHP mail, and verify your “From” address matches the domain. Avoid spammy subject lines, excessive caps, and too many links. Include your business address and unsubscribe/notification preferences where appropriate. Keep templates clean, mostly text with one logo image, and test with mail-tester. Warm up new domains/IPs gradually, and monitor bounces and complaints. Also ensure your server has rDNS, TLS, and consistent sending volume.
