Top mistakes a blogger makes which cost you lots of money

I am writing here the mistakes that i have made and saw other make the same mistakes .

1) Early shift to wordpress

you may see many ads and blog post about the quality of wordpress and self managed hosting  and shift your blog from blogger to wordpress .

I suggest you shift to wordpress when you earn atleast 5$ per month . 

your expenditure should be less than income that you earn online . 

2) Building email list 

website traffic is important for us we need as much as traffic as possible every month to make maximum amount of money . Get subscribers to your blog . 

The main mistake in sending blog post as email to your subscriber .

when you build the email list don't send your everyday blog post to them . if you want to send make a separate list . Most time send your subscribers with ways to make money online or offers that will help them to save money on purchases and you to make money 

3) No of blog post 

people starts a new blog and post some post then they sit and wait for their blog to get million hits . i see people do that and i did that once :P . That is so stupid . If you want more traffic you should have more blog post
