Unsolved Google Ads Subdomain in sitelinks & Composition Change for Strategy Status

[rauoff]

I have a basic query but could not find a definite answer on the internet. I am currently running a campaign for the main website of a big education brand and they also have a secondary learning website on subdomain, and I want to add sitelinks of subdomain to the campaign, but I am not sure whether it is allowed or not.

The brand I am running ads for is https://www.rauias.com/ and the secondary website is https://compass.rauias.com/ branded slightly different in a subdomain, so should I add the sitelinks of Compass to the main campaign?

Also one more silly question

My Max Conversion search campaign gave me this status today.

"Learning (composition change): Campaigns have been added to or removed from the bid strategy. Google Ads is now adjusting to optimize bids.

5 days left for learning"

What does this mean exactly? And Why does it reenter the learning phase whenever I make a small change?

@rauoff Adding sitelinks of a subdomain to the main campaign is generally allowed by Google Ads, but with certain considerations:

1. Relevance: The subdomain sitelinks should be relevant to the main campaign and ad groups. Users clicking the ad should expect to find similar content on both the main website and the subdomain.

2. User experience: Ensure a smooth user experience when clicking the subdomain sitelink. The subdomain website should be visually consistent with the main website and offer a positive user experience.

3. Brand consistency: Maintain consistent branding across both websites to avoid confusing users.

4. Performance: Monitor the performance of the subdomain sitelinks and adjust as needed. If they are not attracting clicks or conversions, consider removing them from the campaign.
