# use cases

Choosing what to build. Compare search demand across use cases and services, then look at CPC (cost per click) to understand how valuable that traffic is. If advertisers pay that much for one click, the revenue behind that service is usually meaningful.

Localization. Compare translated keywords across markets before you localize, and choose the wording people already use when searching.

Content strategy. Run keyword ideas through the API to size a topic before you invest in content, keeping in mind that positions 1 to 3 often capture 30 to 50 percent of clicks.

And more. More SEO tools are coming soon.
