# Feedlinter > Feedlinter audits, fixes and monitors XML product feeds for ecommerce teams, helping prepare product data for Google Merchant Center and other sales channels. The free audit accepts a public XML product feed URL and checks up to the first 10,000 records without an account. It identifies issues such as missing identifiers, invalid prices and availability, and product or image URL problems. Paid plans provide configurable transformation rules, published output feeds and scheduled refreshes. Feedlinter does not guarantee approval by Google Merchant Center or other platforms. Public content is available in English and Polish. Consult the current pricing and product pages for plan limits, supported channels and compatibility details. ## Product - [English homepage](https://feedlinter.com/): Product overview, free audit, workflow, pricing and frequently asked questions. - [Polish homepage](https://feedlinter.com/pl/): Product overview, pricing and frequently asked questions in Polish. - [Free product feed audit](https://feedlinter.com/audit): Audit an existing public XML feed. - [Bezpłatny audyt feedu](https://feedlinter.com/pl/audyt): Product feed audit in Polish. - [ChatGPT product feeds](https://feedlinter.com/chatgpt-product-feed): Product feed preparation for ChatGPT, including compatibility details and limitations. - [WooCommerce product feed plugin alternatives](https://feedlinter.com/alternatives/woocommerce-product-feed-plugins): Comparison of a hosted product feed workflow with WooCommerce feed plugins. ## Guides - [English blog](https://feedlinter.com/blog): Product feed validation, error fixes and optimization guides. - [Polish blog](https://feedlinter.com/pl/blog): Product feed guides in Polish. ## Optional - [Contact](https://feedlinter.com/contact): Contact the Feedlinter team. - [Privacy policy](https://feedlinter.com/privacy): Personal data and privacy information. - [Terms of service](https://feedlinter.com/terms): Terms governing use of Feedlinter. - [Sitemap](https://feedlinter.com/sitemap.xml): Current public pages and published blog articles. - [Robots policy](https://feedlinter.com/robots.txt): Crawling rules for automated clients.
