Only started running these recently and was totally surprised by the results.
Only problem is that I attached them to one specific campaign targetted at blue widgets, but the google product feed uses every widget we sell, so in effect the campaign running is for everything we sell rather than the limited campaign.
Is the simple answer to now develop a range of product feeds, i.e. a blue widget feed, a red widget feed, a baby widget feed, a metal widget feed... and on and on and on. do you see where this is going?
I've scanned a number of pages but cannot find a definitive answer to my question.
Is it best (for me and my budget) to make a number of product feeds OR do I have a number of product Ads or Groups or Campaigns each using the same product feed but with filters.
I don't trust Google not to show inaccurate adverts, i.e. if I leave it to Google to use the product_type to work out what it's going to show I'm sure it'll work it out that I have a product that always meets it's 'algorhythm' in order to burn through the budget.
