Data is 100% permanent once it hits Adobe Analytics data collection servers. As an alternative, you can apply a filter to exclude those particular items from any important reports:
- Log in to Adobe Analytics and access the report you would like to exclude the line items from
- Just below the graph, there is a search filter. Click advanced next to it
- Select the dropdown 'Does Not Contain', enter a value to exclude. Repeat for all pages you'd like to omit.
- The resulting report will not have the specified line items included.
