I know many successful bloggers who maintain more than one blog very efficiently. In this post, I want to share my experience on my advantages of having multiple blogs. When I launched KishPress, I wrote post on my blogs and put some banners on my blog. I also did some campaigns on Google Adsense and FaceBook Ads.
Good news is I could do much more than I expected with the sales of my plugins. I did a detailed study of my campaigns and noted that 95% of the sales was from my own blog. I had run external campaigns only for a few days, got some traffic but the sales from those campaigns were not impressive.
Bottom line is that when you have a blog which has a decent traffic and user base, then you can use that blog to market your new services or even existing products.
