[UA] View filter recommendations

View Filters are a set of rules applied to the data coming into a Google Analytics view to help create reports that meet the needs of the view’s users. As each filter acts on the resulting data from all preceding filters, the sequential order in which filters are applied is paramount.

Applying a view filter has the following effects:

• It will take effect within several hours
• It will affect all new data coming into the Google Analytics view
• It is applied to raw visitor data as the data is processed into the database, that is
  • new filters will not affect historical data
  • Analytics cannot reprocess historical data through the new filter

For the above reasons, it is best practice to apply any new filters to a test view first. Only once the data is considered accurate should the filters be applied to the intended views.

The following filters are generally recommended:

Lowercase Hostname

Use a lowercase filter type on the Hostname

Lowercase Campaign data

Use a lowercase filter type on the Campaign Source

Use a lowercase filter type on the Campaign Medium

Use a lowercase filter type on the Campaign Name

Use a lowercase filter type on the Campaign Term
