One of these bricks and mortar truths that applies online is fact that difference between a new struggling business and an older more prosperous one is simply database of clients and prospects. In most cases, unless products have been totally rejected by customers, larger this data base, more successful business is. And also faster a business can build up this list of prospects and customers, quicker it will grow and reach success.

This database of clients is of course known as an opt-in email list online and same offline truths apply.

When doing an articles marketing campaign it is absolutely crucial that your strategy includes a way of building up your very own opt-in email list, using resource box at bottom of your articles.

There are various ways of doing this. The most effective is to offer valuable information via email. Something related to what attracts readers most to your articles that will force some of your readers to write for more information. Store this information in a auto responder (there are quite a number of free ones online) and your list will grow steadily without too much input and work from you. Initially it will grow slowly but as you build up your number of articles posted online, it will start to grow at a faster rate, reflecting growth of your online business.

2) You can carry out your research on Wordtracker (http://tinyurl.com/8vtcg) and then import your keyword list from a text file. I highly recommend using Wordtracker for your PPC keywords research, because as you will soon find out, keyword counts by Adwords Analyzer can be heavily flawed.

3) The Adwords Analyzer is regularly updated with new features.

Cons:

1) In some cases, Adword Analyser keyword counts are vastly over-estimated as software uses Overture's Keyword Selector Tool to find number of monthly searches. Overture's keyword plurals and mispellings are lumped together. Besides, keywords counts are flawed due to webmasters using Overture for their own keyword research.

2) The software might get you into trouble with Google because it queries Google search engine for its results. Google doesn't allow any automatic query tools.

3) Although it's quite easy to use software, Adwords Analyser lacks a more detailed supporting documentation.

The Adwords Analyzer is a very strong product and offers lots of useful features that can be used in PPC marketing, however, it's not suitable for search engine optimization or profitable niche markets development.

In my opinion, WordTracker still remains one and only reliable tool for profitable keywords research.
