SemaFeed

Why SemaFeed

Exporting products to Google Merchant Center by hand is work that comes back every time a price or a stock level changes. SemaFeed does it for you — and, more to the point, does it so the feed is accepted.

• Prices match to the cent. They are calculated through VirtueMart's own API, so discounts, tax rules and shopper groups agree with what a visitor sees in the basket. A price mismatch is the most common reason an item gets disapproved.
• The feed never goes live half-written. It is built in a temporary file and moved to the published address only once complete. The previous valid version stays online throughout.
• Works on shared hosting. Generation is chunked, so it runs into neither the time limit nor the memory limit.
• Variants done properly. Colours and sizes are sent individually and tied together by g:item_group_id. Images and categories are inherited from the parent.

Features

• Several feed profiles side by side — different range, currency or rules
• Mapping of VirtueMart categories to the Google taxonomy, inherited by subcategories
• Google taxonomy import by download or manual file upload
• Attribute mapping: colour, size, material, age group, custom labels
• Price range, category exclusion, in-stock only, products without a category
• Per-product overrides — replace a value or keep the product out of the feed
• Scheduled generation through the Joomla Task Scheduler
• A log of every run with the reason for each skipped product, exportable to CSV
• Generated feed check — missing attributes, duplicate IDs, malformed prices
• Unit pricing — package volume or weight from a custom field or the product name, so Google can show a price per litre (with a coverage preview before you publish)
• Optional gzip compression, unguessable feed URL
