Free Word Tracker

Using Google's Adwords tool, simply enter in a keyword phrase that you feel is best targeted towards your niche market. I

By simply clicking the search volume tab, you can sort it by the number of searches, so that you can see which keywords are receiving the most volume and which ones are likely to be less competitive, which will be easier to rank for.

Search engines like Google.com will rank your blog pages based on a variety of keyword related factors including:

Accuracy and Relevance of your keywords
Frequency in which your keywords appear within content.
Concentration of your keywords overall.
Closeness of your keywords in relation to each other.
Placement of the keywords within your content.

This means that you want to be sure to feature your keywords throughout every single post or page that you create on your website.

Do NOT just include your keywords within the page titles, but in the actual content as well. While you want to avoid keyword stuffing (where you include so many keywords that your content fails to flow smoothly), you need to do your best to include your primary keyword phrases and long-tail keywords within your content whenever possible.

To create your free Technorati account, visit http://www.Technorat.com and click on the Sign Up link to get started. You simply have to create your profile, and claim your blog so that it can be instantly added to Technorati's database.

Be sure to notify Technorati's search engine of your new blog submission once you have claimed your blog by pinging it at: http://technorati.com/developers/ping/

Another great traffic strategy is to put aside 30 minutes a day to visit other blogs that relate to your niche market, and posting useful comments on these websites that include your website URL in either the body of your comment, or in the information field.

If you focus on high ranking, popular blogs that receive a lot of daily traffic, you can begin to generate traffic to your website instantly, at absolutely no cost.

One thing to keep in mind however, is that your posts should be useful, informative and relevant to the existing discussion. You should focus on participating in the conversation, and increasing back links to your website from relevant prospects. There's no sense in posting comments on blogs that don't share the same target audience as you do.

Do your best to engage the audience and give them a reason to follow your link. Simple comments like "I agree with your statement", or "Great post!" won't do the trick, you need to take it a step further and elaborate on an existing comment, share an opposing viewpoint, or provide a useful resource or tool that those reading the thread are likely to appreciate.

Focus on the most recent discussions as opposed to refreshing an old thread, so that you don't look as if you are only participating in discussions to generate new traffic to your site.

Also be sure to use the same name, avatar (or gravatar) and website URL for each niche market that you focus on so that you are able to build a brand and a following while continuing to establish your online identity.

You will also want to make sure that the blogs you are focused on offer a link back, (dofollow) so that you receive link juice from all of your comments and posts. You can download a fully functional free version of Fast Blog Finder that will help you locate high profile blogs in your niche market that offer back links based on your participation:

There is also a Firefox plugin that will reveal whether a blog contains 'do follow' or not available at: http://www.quirk.biz/searchstatus

This plugin also provides information on page rank, Alexa ranking and other useful information to help you determine the popularity and ranking of any blog you are considering engaging with in order to generate traffic.

There is also a plugin that many professional bloggers have integrated into their website, known as the "Top Commentator" plugin. If you participate in discussions that have integrated this plugin, you can appear as one of the leading posters on high profile blogs, which will expand your outreach and drive in more targeted traffic, easily.

You can investigate potential blogs that feature both the Top Commentator plugin as well as dofollow links by visiting: http://www.dofollowblogs.com/

The more involved you are within the blogging community, the more traffic you will be able to generate to your website absolutely free. While you could set up pay per click campaigns or purchase advertising space on related websites, if you are interested in jump-starting your blogs traffic without having to invest anything more than your time, blog commenting, blog communities and blog directories will help you get started, quickly and easily.

Another effective method of launching your website is by taking advantage of the blog directories online. Some of these services will submit your blog into dozens of directories at once for reasonable prices, while others allow you to manually submit your blog individually into each database.

One of the most popular directory submission services online is called FeedShot and it's available at http://www.FeedShot.com

Take some time to explore the many different options out there and create your marketing "swipe file" that contains links to different blogs and social communities that you can use to further your outreach.

Social communities such as http://www.Twitter.com and http://www.FaceBook.com are also great ways of not only driving in targeted traffic to your website, but in evaluating a market's profitability based on existing demand, questions, products and competition. With both of these social communities, you can link your blog to your social profile with free plugins available on their websites, so take some time to create your marketing strategy and get involved!
