How can I use ad extensions to increase CTR in Google Ads?

How do you optimize ad extensions (like site link, callout, and structured snippets) to increase the CTR and make your ads stand out more on the SERP?

For sitelinks add links to your most useful pages like pricing, contact, or best offers etc depending on your niche, for callouts mention unique perks like "free shipping", "24/7 support", "discounts", bla bla bla.

but thats pretty obvious.

You need to see what works for your LP and adjust things. Without knowing your niche we cant give a 100% detailed answer

Use ad extensions to add more info, highlight offers, and make your ad stand out – more space equals more clicks!
