Google has a [product data specification list](https://support.google.com/merchants/answer/7052112) that outlines the necessary data and formatting guidelines. Adhering to these specifications helps Google accurately match customer queries to your products, increasing visibility and sales. However, the requirements can be overwhelming. This guide will simplify the process by breaking down the **essential product attributes** and providing best practices for optimizing your feed. ### Table of Contents 1. [Required Fields for All Products](#1-required-fields-for-all-products) 2. [Additional Attributes for Shopping Ads](#1-additional-attributes-for-shopping-ads) **Let's start with the required fields for all products.** # Required Fields for All Products 1. [id](https://support.google.com/merchants/answer/6324405) This is your product’s unique identifier. Therefore, you need to use the product SKUs as the IDs since the SKUs are unique. Moreover, SKUs help Google to understand the structure of your landing page. 2. [title](https://support.google.com/merchants/answer/6324415) Your product’s name. You are able to describe your product in up to 150 characters. However, make sure that the important information are placed at the start, because Google will show only the first 35 characters. ![](https://storage.crisp.chat/users/helpdesk/website/ab8a6f89b0a19000/image_c1ffw8.png) 3. [price](https://support.google.com/merchants/answer/6324371?hl=en&ref_topic=6324338) The price needs to match with the one from your landing page, and the currency needs to be related to the market you have chosen for the feed.

[image](https://support.google.com/merchants/answer/6324350?hl=en&ref_topic=6324338) This is the main product image. If you have many different images, you can use the additional_image_link attribute to list them. The ideal main image should be the one taken with a white background that shows a clear view of the product. ![](https://storage.crisp.chat/users/helpdesk/website/ab8a6f89b0a19000/image_1voek6t.png) ![](https://storage.crisp.chat/users/helpdesk/website/ab8a6f89b0a19000/image_k2d0lr.png) 5.

[description](https://support.google.com/merchants/answer/6324468?hl=en&ref_topic=6324338) The product description is the part you can show all the product details. Make sure to include the most relevant features such as size, brand, age and gender to keep your target audience informed.

[google_product_category](https://support.google.com/merchants/answer/6324436?hl=en&ref_topic=6324338) The Google product category shows Google what category your products belong to. If you do not set up categories for your products, Google will assign them to your products automatically. Nonetheless, you should choose the category yourself to make sure it matches your product the best. Luckily, you can do it using FeedHub following this [instruction](https://help.onecommerce.io/en/article/make-your-targeting-more-precise-with-google-product-categories-1374xke). ![](https://storage.crisp.chat/users/helpdesk/website/-/c/b/9/2/cb92164b6e8ef000/1_18b4fd0.png) 8.

If your **price** and **sale price** meet certain requirements, your original price may show along with the sale price, allowing people to see the difference between the two. Similar to the **price** attribute, the sale price also needs to match the one shown in your store. | Google places importance on your feed's accuracy, so make sure every field you set in the feed matches the data on your website. Especially, these following attributes **condition, availability, sales price**, and **price** needs to be updated frequently. Luckily, FeedHub is here to help. You can [set your sync schedule](https://help.onecommerce.io/en/article/introducing-the-new-product-sources-and-enhanced-sources-settings-for-further-feed-optimization-1jxzlqw/) and [your submit schedule](https://help.onecommerce.io/en/article/keep-your-feed-of-highest-quality-with-our-new-enhanced-product-feed-1k7wow8/) to have your products always updated.

For more details on what to do when your product does not have a GTIN, please refer to Google guide [here](https://support.google.com/merchants/answer/160161#withoutgtin). 14.

In this case, the **identifier_exists **needs to be set to **false** or **no**. Since FeedHub uses feed file to submit the feed to Google, you need to set the value as **no**. ![](https://storage.crisp.chat/users/helpdesk/website/-/c/b/9/2/cb92164b6e8ef000/3_p8ru3e.png) 15.
