Since leaving my day job I turned on ads on this blog, via the inbuilt WordAds – managed by WordPress. I thought I’d be back writing this and here I am, in 3 months I’ve earned a total of $1.18. This helps pay 1/10 of my monthly phone bill i.e. not worth the impact on the trackers being enabled and the terrible terrible ads that WordAds serves you. If you are looking to work out your stats then it’ll be around a $0.10 CPM.
Even on a large site this isn’t going to bring in much money and will require other methods of monetisation like sponsorship.
For me I’m turning off ads straight after I’ve posted this and will need to rethink.
