Keyword tags are used in Seelk Studio's Competition app. They allow you to associate multiple keywords under a single category (i.e. tag). 

The main reason to tag keywords if for when you want to analyse the Share of Voice of two or more keywords. 

STEP 1 - Go to Competiton > Keywords
To tag your keywords you first need to go to Seelk Studio's Competition app.

Once you're inside the Competition app select the country for which you wish to analyse your share of voice. 

After you've select your country to will enter the Keywords section of the application where you have various data visualisation of your share of voice for organic, sponsored product and sponsored brands advertisements.

STEP 2 - Select your keywords
Inside the Keywords section you'll notice a list of all your keywords.

To tag keyword(s) simply click on checkbox next to the keywords and then hover on the "tags & groups" button at the top left of the keyword table.

Select "tags". You'll notice a modal that opens. Under "Search, select & add new tags" type the tag you wish to add. If you already have a pre-existing tag, you can select them from the list or simply type for auto-completion. When you're done click "Save". 

Once you've added tags to your keywords, you can apply one or more keyword tags as a filter to your Competition dashboard. 

To add a keyword tag as a filter click on the "+Add Filter" button at the top of the interface inside the filter bar. 

Select "tags" and hit "Apply".

Once this is done you'll notice that all of the data visualisation widgets on the dashboard are now filtered according to the keywords associated with that tag. If you scroll down to the keyword list you'll only see the keywords associated with the tag on which you have set the filter.

To remove the keyword tag filter simply click the "x" next to the filter and hit "Apply".
