How to make money by blogging

There are several ways of making money described in another article: http://www.moneyandinternetbusiness.com/2013/10/how-to-make-money-online-without.html

This time I will try to answer these questions:

Does the topic of my blog influence my earnings?
Yes, in many ways.

• Can you attract enough unique visitors to your blog?
• Are your keywords searched a lot? 
• Or is the topic very specific? (e.g Scientific blog about some specific problem) 

This leads to these two questions:

• Are there any advertisers that might be interested in putting their ads to your blog? 

In google adwords, you exactly choose the keywords for which the ads should be shown - So if your blog is about Techniques of measuring distance between the Earth and the Moon - there is a big chance, nobody is interested in such a topic. 

On the other hand, I love RC planes, and often visit pages about them (those pages leave cookies on my PC), and very often if I visit a page absolutely unrelated to RC planes, there are advertisements from RC plane sellers! 

• Are there enough people on earth I can possibly attract?

The best idea is to research your keywords through google keyword planner. 

Don't forget, the more unique visitors a day you can attract, the better. 

Blogs with the same visitors each day, or high amount of returning traffic are not very suitable and their earnings will probably be much lower compared to the blogs with high amount of unique visitors each day. It's called Ad blindness.

Few ideas on how to get more traffic?

• Make a Facebook fan page
• Research keywords suitable for your blog by google keyword planner
• Be an active forum member, put your website in the signature
• Make a contest with a prize for attracting people
• Exchange links/banners with fellow bloggers
• Pay for advertisement
• DO NOT SPAM!
