How much should one spend on Google Ads for a new ecommerce startup?

[Margaret]

So i will be creating a company that is pretty similar to Music Magpie, Ziffit, We Buy Books etc, in that I will be selling second hand goods that I will be acquiring from customers via mail. My question is, how much should one be spending on Google Ads per month to get the word out and to advertise the site? What would you recommend? Thanks – by /hq/prankster999 – –
