Did you know that you can dramatically increase the number of visitors that come to your site on a daily basis from Google? And it's not constantly improving your position in Google search engine result pages(SERPs) for your competitive keywords which can take some time after working on your search engine marketing campaigns.

I take this example from Google because I've experienced it some time back now. Apart concentrating on getting and maintaining a top 10 ranking in Google, there are lots of easy traffic sources that you haven't exploited yet. We are still talking about search engine traffic here.

What's that strategy you ask? The answer might surprise you but it's a technique that works and is pretty legitimate. It's not creating stand alone or doorway pages with practically no content, overly optimized with keywords and a link back to the homepage. Doorway pages work but only if you know how to do it well. And this article will talk a bit about this topic as well.

The strategy is to search for overlooked keyword phrases which are not too competitive and create effective doorway pages related to these keyword phrases. These pages can be promoting a product for instance.

Just by adding a few effective doorway pages, I managed to make 9 sales in just a few short weeks and earned $364.59.

Imagine you come up with several keyword phrases that generate a few monthly searches, you now have several pages. So each page targeting a specific keyword phrase is worth traffic and not any type of traffic but it will be targeted.

So if you have one page which brings you only 1 visitor per day and you have 50 pages, you can easily receive 50 visitors per day for free. You see the potential now.

Keywords that have about 1000 searches on Yahoo! Search Marketing Solutions previously known as Overture at http://inventory.overture.com/d/searchinventory/suggestion are valuable keywords with lower competition.

If you are using Wordtracker at http://www.wordtracker.com, a keyword with only 10 searches per day can get you a good ranking and bring you traffic.

If you have already a website which is generating traffic, you can dramatically increase your numbers, simply by adding relevant doorway pages targeting a specific keyword. These pages have content and have your optimized navigation menu on it with their specific keyword phrases. These pages are just an entry to your site nothing more nothing less.

They should not be overly optimized with keywords but they must have some optimized content which is readable by your visitors and friendly for the search engines as well.

If you have a good website which is crawled by Google's robot called "Googlebot" often, your new pages will get spidered and indexed fast and will start bringing you small loads of targeted traffic.

But be careful when adding pages, don't go in a frenzy with this and add hundreds or even thousands of pages all of a sudden. For eg if your site has 50 pages already indexed in Google and ranking well and you add 100 new pages at once, your indexed pages might suffer a temporary drop in rankings. The key here is to add pages on a regular basis say 1 or 2 pages daily until you reach the total number of pages to be added.

Why not capitalize on this free source of traffic? The key is to research your keywords well first, work on your content and create these pages afterwards.

Your website will grow bigger and bigger with time and it will attract loads of targeted traffic from multiple keyword phrases.

Good luck and happy research and optimizing.
