How the Product URLs status works
URL Status:
Missing: If the retailer's field in a product is empty then this URL status indicates "missing".
Pending: When you first add a URL to Manage Account then this URL status converts from missing to pending until the next crawl cycle (once per day/week depending on your plan).
Working: it means that the URL is working and we are able to collect data for this product from the retailer.
Not listed: If you know that this product is not listed in this specific retailer you can select this option and stall future searches for this URL.
Not Working: If a URL status changes to "not working", it means that the product page is not available anymore. In this case, the URL should be investigated and replaced with a working URL to continue with data collection.
