Hi Duong,
Thank you for reaching out to us. I see that you'd like to get landing page recommendations. In Google Ads API, we do have a
Recommendation Service that helps you improve your campaigns by introducing new and relevant features, getting more out of your budget by improving bids, keywords and ads, and increasing the overall performance and efficiency of your campaigns. However, it currently doesn't include landing page recommendations. I can request for this feature to be added. In the meantime, please keep an eye on
our blog for further updates and releases regarding this concern. Let me know if you have further questions.
Thank you,
Bryan, Google Ads API Team
