Access the SEO tab to:
1) Control the social, SMS and search previews that are seen when your app is shared.
2) Control if your app will be visible to search engines
Once you have added the SEO "metadata," test it by texting the app to yourself. You will see the preview. Change this important marketing message as often as you want.
Remember that social previews work even if SEO if off and the app is not visible to search engines. When SEO is on, the metadata is also used for search ranking and for search previews.
