What are the potential drawbacks or delays in using Google Analytics for tracking Adwords campaigns compared to PHP methods?

One potential drawback of using Google Analytics for tracking Adwords campaigns is that there may be delays in data reporting, as Google Analytics can take up to 24 hours to process and display the data. To mitigate this issue, you can implement real-time tracking using PHP methods to get immediate insights into your Adwords campaign performance.

// PHP code snippet for real-time tracking of Adwords campaigns

// Set up a connection to Google Analytics API
$client = new Google_Client();
$client->setAuthConfig('client_secrets.json');
$client->setScopes(['https://www.googleapis.com/auth/analytics.readonly']);
$analytics = new Google_Service_Analytics($client);

// Get real-time data for Adwords campaigns
$realTimeData = $analytics->data_realtime->get('ga:XXXXXXX', 'rt:adClicks,rt:adCost', array('dimensions' => 'rt:source,rt:medium'));
print_r($realTimeData);
