Massive Income Network writes from experience running blogs for years, and the strongest post here admits the expensive lessons that came with it rather than only the wins, correcting the common misconception that blogging produces easy money once you understand it is genuinely a lot of consistent work first.
The AdSense post is the most specific of the four, explaining that earning meaningful money from Adsense clicks requires real traffic volume, and that this traffic has to actually match your content rather than arrive from unrelated sources, since mismatched visitors will not click regardless of how much of them you attract. The Ezine article post makes a parallel point about how article marketing has changed, noting that early Ezine writing aimed mainly at pleasing search engines while today's version aims more at readers first.
None of the four posts name specific numbers or a specific blog by name, staying general enough to apply to nearly any online marketing effort rather than to one traceable project.
Read the blogging lessons post first for the most honest material. The AdSense and Ezine posts work as a pair if you are choosing between those two traffic strategies.
