Im doing a travel review site.. should i put adds in now or hold out for a while? last site i did them as i was making it and has worked out not to bad.. Only down fall about doing it later is inserting them in everywhere.
Personally i usually build my blog, set it up, buy the url, list it in all the social networking places, do my first article and the last thing i do is put the adds in, however i do try to knock this all over in one day. I say why not? if you earn $2 , $2 is $2 more than you had before
