The scheduler allows you to schedule tasks such as building shopping feeds, schedule custom reporting, importing your store, etc. Simply check off the tasks to run and select the frequency of the task to run, then click on Activate / Deactivate. It is advised to run most feeds every few days. It is not advised to run a feed daily if the size of the feed is larger than 50,000 products. Some sites (such as share-a-sale) do not allow you to send product data more than a few times a month. For these sites, set the frequency to 7 days. You can view the product count relative to the product import.
