Have a blog with adverts

If you take good photos and can write an interesting blog about your caravan trips (or about anything else, for that matter!) that you think other people may want to follow, (www.blogger.com for instance) you can 'monetize' (just love these made-up words!) your blog by including related adverts- you then get paid for the number of people who have visited your site and so have supposedly read the adverts (if they don't have an advert blocker!).
