Every time I login to write a new blog I'm presented with the option to 'make money from your blog'. IE to add Google adverts to the Travelling Online blog site.
Tempting.... but no.
We already have enough Google text ads on the Travel-Lists.co.uk site, and I tightly control them so they don't become too obtrusive (eg not on the home page or slowing up any navigation pages).
Sometimes you can have just too much of a good thing!
