Visa and MasterCard are both trying to improve their credit card verification system to cut down on fraud.
Visa said, "...while just 6 cents of every $100 spent with Visa cards as a whole is fraudulent, that number jumps to 24 cents for Web transactions."
Although MasterCard declined to reveal how they are going to work out a more secure system until this weeks CardTech- SecurTech show in Las Vegas, this is what Visa plans for their 3D secure system:
"Based in part on Arcot Systems Inc.'s TransFort payment authentication software, 3D Secure enables card-issuing banks to confirm a card holder's identity to an online merchant during the checkout process. When a shopper on a PC or a Wireless Application Protocol-enabled phone is ready to check out, the Arcot technology launches a pop-up screen where customers are required to enter a password after they enter their credit card information. The password is authenticated, not by the site, but by the bank that issued the customer's Visa card, before the transaction can go on."
A doorway page is built to rank high for a particular keyword or search phrase. When your doorway page is visited by the searcher it simply has a "click me" button which links to your web site. The major search engines accept these pages as long as the end result does provide what the searcher is looking for. If you are discovered to be using doorway pages for irrelevant keywords you can expect to have your entire domain unlisted. For instance, one of our doorway pages is built to rank high for the search term -netobjects 5 download---which is quite acceptable because when the searcher gets here he can download a trial version of the software from our site. If however, it weren't available for download then we would risk the wrath of the all powerful search engines.
Once you have selected your keywords and phrases (about 50 would be the normal) you need to build a doorway page for each keyword and ideally, for each major search engine. All the major engines look for different keyword density in the text, title and description so you need to do some research by doing a search using your chosen phrase or keyword and studying the top 10 results at each engine (if you can spot them, study high ranking doorway pages).
Make notes of how many times the phrase or keyword is used in the title, description and body text. Is it used in header text etc? Once you have built a picture of what your doorway page should look like you can build it using your favorite html editor.
Once you have done one for a particular engine the other 50 or so pages can be done by simply replacing keywords for keywords. After you have done a page for each keyword move on to the next search engine. Remember that your body text is not important but make each page unique or it may be considered spamming. It is your keyword or phrase density that you are attempting to get right. The page, when visited by a person, will be recognized for what it is, simply a link to the real content so don't worry too much about what it looks like. When a search engine spider visits the page it is only interested in counting the keyword density in your body text.
As you have probably worked out there is quite a lot of work involved. 50 phrases or keywords=50 pages X the top 8 search engines= 400 pages. In reality though, you are only creating 8 doorways, 1 page for each search engine. For all the other pages you simply have to substitute the keyword for the next and alter the text around so as not to finish with 50 identical pages. OK, nearly finished but the next step is crucial if your doorways are to work.
Put all your pages in a folder on your server e.g. Mydomain/doorways/. Then create 2 more pages that have a link and a small description to each of your doorways (200 on each) and to each other. These are called corridor pages because the spider travels down them, visiting each page linked off them.
Call these 2 pages index and home and place them in the folder with your doorway pages. Then place links to these two pages from your main index page so that a spider will be able to find them and list all your doorways. You can use a small 1x1 pixel graphic as a link. Submit only your index page and your 2 corridor pages. Do not submit your doorways to the engines.
Ideally, and if you can afford it, you should set up a new domain and host for your doorways. This isn't essential but it does have benefits. These are: If you do get over zealous with your doorways and an engine does ban you for spamdexing at least your real site will be safe. Engines rank sites higher if they have lots of links to them from other domains. You can put your most important keywords in your new domain name, which will increase the ranking of the doorway pages containing those keywords.
Now all you have to do is wait for the engines to update their databases. We have had the best results with Google.

I hope this helps in your future marketing decisions.
