As most of you would be knowing, display network performance is being shown on keyword level nowadays. Does this indirectly imply one can use broad match modifier + symbol to keywords on display network?
For example, earlier if I was bidding on keywords like mechanical jobs and engineering jobs, now will I be able to bid on +mechanical jobs, +engineering jobs etc? This will prevent my ads to get displayed on pages with closely similar keywords like electrical jobs, machine tool jobs etc and I would prefer this way because I know these 'closely similar' keywords are not going to contribute to my ROI.
In case if this works, this will help me to increase the relevance of pages where my ad will be displayed and the process will be much easier than adding negative keywords.
Please someone help.
