The bloggers has to monetize their blog so they could afford their hosting and household expenses. The biggest disadvantage of monetizing with advertisement is this that you are sending your visitor to another site. It is something similar to hitting yourself. By doing this we are allowing our visitors to leave our site immediately. We have a solution or suggestion for this.
Put widget for recent post and post popular post on your blog. Your visitor will keep revolving around your site by doing this.
If you want to earn from your site then try to sell or buy things at your own blog rather monetizing it. Uo will get more traffic and as well as direct profit from buying and selling.
If you have any suggestion for this then please share it.
