previous negative keyword still blocking my ads
Re: previous negative keyword still blocking my ads
If you have removed the negative keyword from the list then it should not ideally block the ad for that keyword.
Can you make sure that keyword was added at the campaign level or at ad group level.
There might be a possibility that, keyword has been added as negative at campaign level and also at the ad group level and you removed only from ad group level.
Try checking using the ad preview and diagnosis tool from keyword tab > status column > hover mouse over bubble and click on “ad preview and diagnosis” tool.
Does this help.
