Advertising:-
When trying to add advertising to your blog it is best to know what's on offer, so you can make up your own mind what to use on your blog and also to know how to use them effectively on your blog. There are a range of Advertising sites that have the codes to add to your site and here are a list of some of the best ones that probloggers use on their blogs and I'll evaluate and add more once I've tested them out:-
Kontera - A blog plug in, that delivers high quality text links that pay when someone clicks on the ads that pop up in the form of a preview ad box.
Google Adsense - Adsense is one of the most well known contextual ad networks there is and it is the most used by webmasters and bloggers around the world, all you do is put the code for the ads on your blog or around relevant content and the ads will show relevant results for the content that is being displayed and you earn from the clicks and impressions that the ads generate, but never click your own ads as this is click fraud and you'll lose your Adsense account.
Chitika - This is similar to Adsense were relevant advertisements are served up based on the surrounding content and you earn from the impressions of those ads and plus there is an affiliate referral option were you could earn 10% of the sign ups earnings.
