Update (5/17): Starting October 30, 2018, parallel tracking will be required for all AdWords accounts. See the AdWords blog post for details.
AdWords now allows you to
enable parallel tracking for all advertisers from frontend and API. People who click your ads will go directly to your landing page while their browser handles click measurement requests in the background. This helps reduce lost visits which can happen if a customer clicks on your ad but never sees your landing page because they navigate away before the redirect from your tracking URL completes.
All ads using third-party click measurement will begin using parallel tracking at a later date. However, you should start developing for compatibility as soon as possible to give yourself enough time for the migration. If you implement your own click measurement server or provide this service to your customers, refer to our newly
published guide for help with implementation. If you are an advertiser who uses a third-party measurement solution, reach out to your service provider to prepare for the switch.
