I am considering advertising on Facebook. What is holding me back is knowing that AdBlock can simply prevent all the ads from view. I use a browser that has Adblock built in. I never see ads when I visit Facebook. I cannot find any studies that report on how many people use Adblock or how many use Adblock to block ads specifically on Facebook. I guess what I am wondering is how much does Adblock affect Facebook advertising. Does anyone have any thoughts on this issue? Thanks.
