This article introduces Conversion Linker.
What is Conversion Linker
Conversion Linker will automatically detect ad click information, such as gclid, in the conversion page URL, and then store this information in the first-party cookies _gcl_dc and _gcl_aw, which can effectively evaluate conversion and attribution.
Why need Conversion Linker
Because Apple’s ITP rules restrict the use of third-party cookies, and Adwords uses third-party cookies, this will result in conversions not being tracked.
Therefore, Google launched Conversion Linker, which allows the information originally stored in third-party Adwords to be stored in the first-party cookies gcl_dc and _gcl_aw, and can continue to be used to track conversions and attribution normally.
When to use Conversion Linker
- If you installed GA4 and Adwords conversion through hard coding, no installation is required
- In other cases, installation is required
Therefore, Conversion Linker basically must be installed.
