Your profile holds the potential to affect your readership base
5 ways to manage your profile to turn profile visitors into sticky readers:
A person maybe compelled to visit your profile if your blog he has landed on is interesting enough to urge him to find out more about you, to find whether you have any other blogs that would make a good read. So this fact should be understood very well that the 1st thing that is noticed in your profile is your blogs. In this scenario, owning too many blogs is okay till you have them regularly updated and just as interesting as the one profile visitor came from.
On the other side, the visitor might happen to be coming from another blog of yours that is not regular updated and/or offer quality content expecting to find something better. In this scenario, having too many blogs may have a negative effect if the “good blog” is not easily spotted. So, I suggest if you are experimenting with many blogs at a time, or have too many blogs but are seriously involved in a single blog, updating and maintaining it well and offering quality content then you should use dummy accounts for maintaining the other blogs. You should not let your experiments or try-outs become stones hindering your success.
