# 3 - Groups
On this section of campaign creation you set all details (content, number of links, account bucket etc) for each link group separately.
On the left side of the screen **(1)** you can select different filter options to show/hide link groups.
On the right side of the screen **(2)** you set each group settings.
### Group Filters
Group filter help you filter group types according to different criteria. This helps the screen to remain "clear" and less overwhelming.
There are three different filter types:
* **Per Tier View** : filters groups according to their tier level (more info on [**diagram tiers**](https://docs.seoneo.io/~/changes/c3esrpjGy8mxnwIOXO75/additional-information/glossary/tiers))
* **Per Group Type View**: filters groups according to link group type (more info on [**group types**](https://docs.seoneo.io/~/changes/c3esrpjGy8mxnwIOXO75/software-overview/diagram-editor/link-group-types))
* **Groups With Validation Errors**: show only groups with errors while the user sets group data.
To better understand each group filters, we will show you the selected diagram used on this example:
