Running maximize conversions search campaign for leads and averaging around 30CPL for the month using smart bidding. No tCPA in place because daily budget is only 100 and cpl is 30. 75% of days the campaign gets 5-10 leads per day at under $20 cpl. 25% of the day the campaign excessively overspends and brings in close to no leads, absolutely ruining avg CPL. Location targeting is where I need it to be, but the campaign is just so unbelievably inconsistent. Currently just running 1 ad group with 4 broad match keywords and a VERY large negative list. 2 keywords with the lowest QS are performing the best with lowest CPLs. Other 2 keywords have the highest QS and have the highest CPLs. All 4 keywords are very important so I can't really delete them. Not sure if the issues here are just customer related with people not wanting to opt in or if something is not working with the campaign.
