So I'm launching my first google ads standard shopping campaign for my ecomm brand. My plan is to use manual CPC until I get 30 conversion in a 30 day period and then switch to targeted ROAS. I think I know what I'm doing but I have some questions. I'm not sure I can get enough conversion volume to make a target ROAS strategy work long term. My products are relatively niche and the keyword planner doesn't give me much insight on volume. Is there a way to know the viability of a target ROAS campaign before spending thousands on manual cpc to try to get the minimum conversion data or do i just have to try it? I launched the campaign a couple days ago but am not seeing many impressions (about 60 a day) and no clicks. Does it take time for more volume of impressions to start or are my bids just not high enough? Any insights would be appreciated, thanks.
