GSA Search Engine Ranker V7.18 - How to use the edit single option feature
All check boxs accept values 1 and 0 :
1 is to enable the checkbox
0 is to disable the checkbox
For single options with multiple possibilities, you can deduce what value is needed by editing 2 projects with the options you want, then selecting only those to projects to edit with the single edit option.
The default value shown in the prompt is the value for that option.
Hope this helps!
