How do I sync iPhone Contacts to Google Contacts?

How do I sync my iPhone Contacts to Google Contacts? Google’s instructions say: > 1. On your iPhone or iPad, open the Settings app. > 2. Tap Contacts. You might need to scroll down. > 3. Tap Add account. If you've already synced a Google Account to your device, tap Accounts. > 4. Tap Add account and then Google. > 5. Follow the instructions to sign in to your Google Account. > 6. Choose which Google apps to sync with your device. You can update these settings at any time. > 7. Tap Save. > > To start syncing, open your iPhone or iPad's Contacts app. Upon doing that, I now see in iPhone Contacts app several “Lists”: One for “All Contacts” with 7,425 contacts; a second for my Google account with “0” contacts; and a third for “All iPhone” with 7,425 contacts. Looking online at contacts.google.com , I see zero contacts. So… How do I get my contacts from my iPhone into my Google account?
