Blogging is a great way to make some money including side income or even more income than your current job makes.
Some bloggers make as little as $100.00 per month while others make $3,000.00 , $5,000.00 and even as high as $10,000.00 to 20,000.00 per month if there blog is popular enough and has been around long enough.
I have a blog that started out making nothing for the first few years it was online but during those years and after I continued to write new blog posts and as the blog got older it started making $500.00 per month and then $1,000.00 per month and now 10 years late the blog is bringing in $8,000.00 per month.
If I continue to work on the blog it could even make more money than that over the years.
You must work hard at the blog though and I make all that money from Adsense alone but some people sell E Books and other affiliate programs to make even more money.
Blogging won't bring in an instant income but if you continue to work on the blog you'll see results from Adsense or even other income sources after some years of blogging.
If you continue to blog you could have a very nice retirement income after all those years of blogging as it costs very little to keep a blog going.
The longer the blog is online and the more often you post quality blog posts that get lots of searches the more income you will make because you'll have more website visitors which equals more income.
You could even eventually sell your own ad space which could make even more money than Adsense or other income sources.
