I’m guessing that if you do any kind of Internet marketing that you’re already familiar with Google’s Search-Based Keyword Tool. If not, you need to be. It’s still in Beta as of this writing on March 20,  2009, but it works great.

I’ve gotten several emails from other marketers, some with videos, on Google’s newish tool that is one that you’ll use regularly if you’re looking for niche markets often

If you haven’t been using the keyword tool, you can go to Google.com/sktool to check it out. It really is very useful, and although I use Micro Niche Finder, and now Market Samurai on a daily basis (well, at least MNF, MS still has some bugs, but it looks very promising, it does certain functions now though), having this Google tool just a click away will surely be extremely helpful.

Actually, with just the resources available for free online, you can easily find just the right (micro) niche for you, and do all the keyword, domain, competiton and affiliate research that is necessary to become profitable in a wisely chosen niche. If you’re really tight on money you can actually start generating an income from the Internet with nothing more than a computer and Internet access.

I guess you’re actually using the Search-Based Tool in reverse, as it looks as though it’s intended to help you find the best keywords for an existing site that you may have. Of course it doesn’t really matter, as long as it shows you the keywords, you can then use the standard Adwords Keyword Tool in conjunction, to find the best little niches that anyone could hope for.

When doing niche research, just click ‘Or see top keywords across all categories’ across the bottom of the screen.

Happy searching.

Here’s how Google describes the Search-Based Keyword Tool – complete with their disclaimer.

What is the Search-Based Keyword Tool ?

The Search-based Keyword Tool generates keyword and landing page ideas highly relevant and specific to your website. In doing so, the tool helps you identify additional advertising opportunities that aren’t currently being used in your AdWords ad campaigns.

Based on your URLs, the Search-based Keyword Tool displays a list of relevant user queries that have occurred on Google.com (and on other Google search properties, such as google.co.uk) with some frequency over the past year; these suggestions can be found under the Keywords tab, in the New keywords related to (site) section. In the Keywords related to your search section, you can see a broad list of keyword ideas that are also relevant, but aren’t necessarily based on your site.

The keywords are also organized by category. Click any category to expand and view its subcategories. If applicable, you’ll also see the keywords organized by brand names.

Important note: We can’t guarantee that these keyword suggestions will improve your campaign performance. Additionally, we reserve the right to disapprove any keywords you add to your campaigns. You’re responsible for the keywords you select and for ensuring that your use of the keywords doesn’t violate any applicable laws or our Terms of Service.
