With a catalogue, you can upload your inventory to Catalogue Manager and then promote your inventory in multiple places, including Facebook, Instagram, the Audience Network and Messenger. Catalogues can be used across a variety of business types and across different solutions, from e-commerce to travel. Use this guide to learn how to effectively use catalogues.

Choosing how to add items to a catalogue

How you add inventory to a catalogue depends on how you want to use your catalogue:

• If you want to use retargeting ads (for example, dynamic ads): Set up a data feed for your inventory. A data feed is a file that contains information about the inventory that you want to upload to Facebook. You enter different attributes about your inventory so that Facebook can take the information and populate your catalogue.
• If you want to tag your inventory in posts on Facebook or Instagram, or you don't have the resources to create a data feed: Add products manually to a catalogue. You can individually add items from your inventory to your catalogue without creating a data feed. You can add images, names, descriptions and prices for each item that you're adding to your catalogue.
• If you host your inventory on another platform: Connect your Shopify, WooCommerce, BigCommerce or Magento account without needing to set up your inventory again on Facebook.

Setting up a data feed

• Review the images in your catalogue to ensure that they are eligible for all placements and compliant with our content guidelines: Products that do not meet content guidelines or image specifications will not appear in your dynamic ads. For square (1:1) aspect ratios in the carousel ad format, your image should be 600 x 600 (500 x 500 for Instagram). For single image ads, your image should be at least 1,200 x 630 (500 x 500 for Instagram). It's also recommend that you use high-resolution photos (1,080 x 1,080) for the best-quality imagery.
• Check your URLs: Each item in your inventory should have a destination URL. URLs should start with http, https, ftp or sftp. When people see an ad from your data feed and select an item, they'll go to your website or app to learn more about the item. If the URL is incorrect or not properly formatted, your ad won't link to a destination.
• Create a product set: Product sets allow you to filter groups of similar items that you want to advertise in a particular Facebook ad. With product sets, you can control the items that appear in your ads.
• Associate a Facebook pixel and/or app to your catalogue: Associating a pixel and/or app to your catalogue allows you to maximise the potential size of the audience. You can then see how many people interacted with the items in your catalogue based on pixel or app activity.
• Consider providing "product_category" and "product_type" as columns in your feed (e-commerce): Using these columns may allow for more reporting options, delivery optimisation and targeting options (cross-sell/upsell).
• Make sure that every product in your catalogue has a unique identifier (e-commerce): Providing unique global trade item numbers (GTIN), part numbers, unique titles and descriptions can help prevent duplicative records and improve your ads' delivery.

Maintaining your catalogue

• Keep your catalogue up to date: Add high-quality and accurate information about your inventory to help improve ad performance. For example, showing in-stock products with correct prices can help conversion rates and create a better experience for shoppers.
• Schedule uploads (data feeds): If your catalogue changes constantly and your feed is hosted on another server or website (such as Dropbox or an FTP client), you should consider scheduling updates to your catalogue. Learn more about scheduled uploads.
• Review your pixel data (data feeds): Check that your pixel is correctly firing the right events by visiting the corresponding product page with the "link" value in the product feed, checking that the pixels fired with Pixel Helper and comparing the "content_type" and "content_ids" against the data feed used.

Uploading info to your catalogue

• Compress data feed files for large files: You can upload compressed data feed files that are up to 30 GB in size. The limit is on the file size for the entire data feed rather than number of products in the data feed.
• Make faster changes to your data feed using the Update Schedule option in Catalogue Manager. You can access the scheduling options by going to the catalogue in Catalogue Manager, selecting Settings and choosing Update Schedule. Updating the schedule and not replacing the schedule ensures that your data feed isn't completely deleted.
• Save time by splitting your data feeds if you have an hourly schedule. It takes much longer for one large data feed to be uploaded than it does to upload multiple data feeds.
• Consider using the Products Batch API (for developers). The Products Batch API was designed for large catalogues with quickly changing inventory. It allows you to create, update and delete multiple items in a single HTTP request. Learn more about the Products Batch API.
