You can add sites to a slashtag directly from the search results page. You must be logged in to add sites to a slashtag.
- Click on the “add” link on the line directly below the webpage title for the site you’d like to add.
- Enter the name of the slashtag you would like to add the site to.
- Check the box to “add entire site to slashtag” if you wish to add the entire domain and not just that specific link. (If the result is a domain, you won’t see this option).

Problem is that this feature is not remember the last used “slashtag”
When searching blekko index and collecting sites for a new “slashtag” … you need to select the slashtag everytime.. you want to add a site.
