You guys haven't set me wrong yet so I'm asking again. http://www.joysandsorrows.co.uk/?page_id=10 See the Google Ads at the top of the page? Someone wants to replace that banner - sitewide. The blog is ranked PR 6 and gets around a thousand uniques per day. How much - roughly - should I be charging per month? Any help appreciated.
Well you could just shift the google advert to the bottom of the posts. Then I'd look at your cpm for the google adverts say its $1.5 cpm and multiply that by the number of impressions that its gonna get, say 2000 a day = 60,000 a month = 60 x 1.5 = $90 That's just a theory, I just thought of it now it seems a bit expensive, guess it depends how much they want the advert.
Whatever you do, don't base what your charge for CPM on the number of unique visitors. Base it on the number of page views.
