Do your products’ prices change more than once per day?
Or do products easily go out of stock during the day?
If so, this script might be of interest to you:
Fetch Google Shopping Feeds Every Hour of the Day
URL: https://nilsrooijmans.com/google-ads-script-increase-shopping-feed-update-frequency/
What it does: This script fetches your shopping feed every hour. This way, all the data in your Merchant Center and Shopping Ads is always up to date.
Why you care: The Google Merchant Center interface only supports once-per-day updates of the product data in your shopping feed. Because of this fetch rate limitation, your shopping campaigns may show outdated product listing ads on the Google SERP.
