How much money do you earn from every 1000 people you get from Search engines. Please also precizate your industry
it is also very important how targeted is the traffic, even if it is from SE, some have wider range of kws while others have very targeted which of course has better conversion
Do you sell your own products?! Or you advertise other websites using affiliates link?! Or AdSense?! I mean you earn those 200 USD from direct/indirect sales?! or from PayPerClicks?! (Adsense)
