How can I advertise my blog :)?

[Monkey]

The best free advertisement is to be highly ranked with the main search engines (Google, Yahoo! and Bing). You need to write your post following SEO best practices. There are many free WordPress plugins to help you do that. Try to use rich snippets as well to catch readers' attention in Google results.

Other free methods that are time consuming include blog commenting, forum participation, blog directories subscription, guest posting, etc... But time and money are interchangeable. So if it's a free method, it means you will need to spend a lot of time on it. Paying for advertisement means removing that hassle with money. There is no free and hassle-free way to promote a blog. Social networks are the closest to that if you have enough connections.
