Put the subscription dialog on your permalink pages

Of course you have the subscription form or link on your main blog page (right? right! Just checking...).

But if a user clicks on a link to your blog in a search engine like Google or Yahoo, they're much more likely to land on your individual post or item page, where your content stands alone.

Go on, try it - visit your own blog and click through to the individual entry. Can you subscribe from there? You should be able to! Update your template to include subscription options in your sidebar for all posts in all pages, not just your blog's main page, or include subscription links in each individual post. Don't forget to republish the entire blog when you're done.

If the form is too much, try the FeedBlitz chicklet - not only does it show your subscriber growth, it is a link to a signup form for visitors.
