Do you mean you want visitors from blogger.com to go to your blog or do you want visitors to your blogger blog? Either way, get some quality backlinks going...comment on similar blogs and maybe email the owners for a blogroll link. Just a start...
Just like any sites, for you to have more visitors, put some interesting content to your blog and spread it all over the internet through link building. In this way, there's a big chance of getting more visitors to your blog.
If you write something interesting, controversial or any manner that people would interest to read, they will surely find you in any way.
Write unique and good content, create solid backlinks, post in forums and other blogs, use social media and social bookmarking.
If you are referring to the blogspot bloggers, I mean the followers, then I would advice you to go in the social network site called blogcatalog.com and register your blog there. There are millions of bloggers who will accept your friend request and even become your followers on your blogger blog. However if you are just asking for a traffic from any source to your blog, then you have to make some link building plan to increase your backlinks
Considering you don't have a budget for buying links and advertisements. Youtube is your friend. The easiest and fastest way to get traffic on your websites.
Daily update your blog with quality content. Perform social bookmarking of each published post and build some quality links for your blog.
There is nothing as effective as content and backlinks. So update your content regularly and keep continuing link building.
It is same method used to increase traffic no matter on blogger or self-hosting blog I strongly suggest use SEO and SMO
Good content then put your links in social media , and u can create Facebook page for your blog and post ur links on it
Promote RSS feeds, try that maximum people subscribe RSS feeds, create backlinks, Blog commenting and last and most important SMO
In case of blog the main thing is the content should be unique if it is not unique then you can't get much traffic, the way of promotion may be many, you can join blog network like technorati, you can join some related forums as well.
Thanks for the very useful directory which I will add to my blog. I should get back into directories again, but perhaps restrict to just a couple. Often I used to get saturated with members promoting groups/private messages/etc, but found them very time consuming to partcipate...
