Depending on where you want to take your business, a multiple niche website can be an excellent platform with which to expand your business and cover a larger market. It could also be a good choice for you if your interests and expertise vary greatly. However, you also have a choice to just focus all your energies on building one site and staking your reputation on it. So will a multiple niche website be a good choice or will one big authority site increase your chances of success? Let's take a look at the benefits and limitations of each option:

Multiple Niche Websites:

A multiple niche website offers you an opportunity to reach several different segments of the market all at once, allowing you to cover as much ground as you can using just one or a few sites.

Advantages

A multiple niche website lets you communicate to multiple groups of potential customers and possibly close a business transaction from there. It also helps maximize your initial website building efforts, particularly because you only need to build each site around a single design concept.

Multiple niche websites can also showcase your flexibility and comprehensiveness of services that you offer. It's like having a multi-specialty site that attracts clients and customers from several different market segments and then doing business with them. Once your site has been around for sometime, it could easily pick up a minimum of 1,000 to 3,000 hits per day - even more when you've gained enough reputation and recognizability in the business.

Disadvantages

The disadvantage of a multiple niche website rests mainly on its design. Since you will be promoting different products and/or services from a single site, imagine how it would look like to a visitor. One site = hundreds of related links. And we're not just talking about internal links either.

A multiple niche website is essentially your store from which you'll be running your business. Once you're actively participating in the industry, it shouldn't be long until you find external links that you might want to refer to your visitors. Now imagine the chaos - dozens of links, banners, buttons, ads, graphics, pages upon pages, all coming from just one direction, each one crying out for attention.

If you can't manage it well, a multiple niche website can grow to be a multi-headed monster, each one heading for a different direction and demanding a different type of approach. In the end, there is a danger that you could be competing with no one else but yourself.

Build multiple niche websites if...

- You have the expertise and the experience in the specific niches you want to focus on.

- You have the skills, time or manpower to devote for the development of each niche.

- You have the resources to spend for the demands that a multiple niche site will require.

- You have established an organized and well-designed business processing system to handle transactions such as sales, discounting, customer service, subscription, etc.

- You have the patience of a saint and the eye for detail of an IRS auditor.

Single Authority Site

The single authority site is just that - one site offering excellent products or services pertaining to a single niche or industry.

Advantages

One big authority site is perfect for people who want to build their expertise in only one field or niche. If there's one thing you can do well and you want to make it your business, take this route. It's easy to set up, doesn't require a lot of resources and is relatively cheaper to run. You could also concentrate all your efforts here and become a respected guru in a specific field instead of being the internet marketer who juggles with multiple industries and never quite achieving expert status.

Disadvantages

If you made a mistake in your choice of niche, a single authority site can fizzle out like a short matchstick. When it goes, it goes and there's nowhere else you can turn to or fall back on, unlike a multiple niche website where there are other things going on for you.

You could also miss the opportunity of providing products and services for a wider market segment, thus limiting your income potential. If the niche you chose has a limited market, your site's traffic counter will reflect that in the number of hits it receives.

Build one big authority site if...

- Your expertise is limited to only one area and you are confident you can comfortably grow in it.

- You want to become a known authority in that niche.

- You have limited knowledge or training.

- You want to focus all your time, effort and money developing one big authority site versus a multiple niche website.

An SSL, or Secure Socket Layer, is technology that has been developed that allows web browsers and web servers to communicate over a secured connection.

The system uses cryptography that uses two keys to encrypt data  a public key known to everyone and a private or secret key known only to the recipient of the message. It’s a way to encrypt data, like credit cards numbers (as well other personally identifiable information), which prevents the "bad guys" from stealing your information for malicious intent.

The recently introduced SSL v3 improved upon SSL v2 by adding SHA-1 based ciphers, and support for certificate authentication. SSL v2 was known to be flawed in a variety of ways. Identical cryptographic keys are used for message authentication and encryption. The older version did not have any protection for the handshake, meaning a Man-in-the-middle downgrade attack could go undetected.

SSL has recently been succeeded by Transport Layer Security (TLS), which is based on SSL and is included as part of both the Microsoft and Netscape browsers and most Web server products. SSL uses the public-and-private key encryption system from RSA, which also includes the use of a digital certificate.

SSL-enabled client software can use standard techniques of public-key cryptography to check that a server's certificate and public ID are valid and have been issued by a certificate authority (CA) listed in the client's list of trusted CAs. Client authentication allows a server to confirm a user's identity. It’s a way to assure a client that they are dealing with the real server they intended to connect to. It can prevent any unauthorized clients from connecting to the server, preventing anyone from meddling with data going to or coming from the server.

From the very beginning SSL was designed to provide security between client and server, and to avoid any kind of 3-way man-in-the-middle attack.

Conceptually it’s quite simple: it negotiates the cryptography algorithms and keys between two sides of a communication, and establishes an encrypted tunnel through which other protocols (like HTTP) can be transported. It can also be easily passed through firewalls and proxies, as well as through NAT (Network Address Translation) without issues.

What is PHP?

PHP stands for PHP: HyperText Preprocessor, it is a server-side scripting language, and as the name goes, it is to create dynamic and interactive Websites for your visitors. Maybe you currently make your Websites in HTML? HTML alone cannot create dynamic Web pages, HTML is clearly defined as a static language, as it is always static and mainly is used for structuring (or styling, in some cases) a document (or a Web page, if you like).

What do we mean by server-side scripting?

You may already know, but HTML is a client-side language, so the browser translates the HTML code into "bytecode" that the computer can understand, and so the computer translates bytecode into what we can clearly understand, text, for example. Server-side scripting is a little different, a little bit more added to the story. As with PHP, server-side scripting languages have an interpreter inside a machine, that translates the code (in our case, PHP code) to HTML code (that the browser can understand), and then the same process will take place with the browser translating the HTML code to bytecode, and so forth. With server-side scripting languages, you don't need anything adding to your browser or computer, as the interpreter inside the machine that hosts the particular Website does most of the work.

What's the fuss with server-side scripting languages, then?

The thing that makes server-side scripting a must nowadays is because it can generate dynamic Web pages, but what do we mean by dynamic Web pages? Well, imagine you wanted to start a forum, and you used HTML. Okay, you used a form to submit the data and it is sent to your e-mail address, and you have to edit the static Web page every time you want a new post added. That, to me, would be the most annoying job of creating a Website. However, with PHP (or any other server-side scripting language, for that matter), can be completely automated, and you'd not have to edit your file even once! The thing that PHP does, is sends the form data to a different page, saves it in "pre-defined" variables (things that store a value), and using something called a "while loop" that continually loops all the posts saved in the Web page - and that's it! PHP stores the posts in a MySQL database (something that holds data, if you like, like member accounts, etc) and uses that as long-term memory.

But if we're talking about server-side scripting languages, what makes PHP different from the rest? Well, simply put, PHP is probably the best thing that has come into the server-side scripting genre. If you have heard about other scripting languages like Perl or ASP/ASP.NET, you'll come to find that they are extremely hard to learn from. Put it this way, the majority of Web developers that use ASP.NET, for example, are those who have come from a different programming background, like have known VBScript, or other languages that's in relation to ASP.NET, the same with Perl. The difference between PHP and the rest, is PHP is incredibly easy to learn, especially for the newbies towards this industry, and PHP has took several steps to ensure an easy introduction to those newbies to the world of programming. Let's do an example, lets see which is the easiest to understand, out of PHP, VBScript and Perl, by doing a simple "Hello World" program, that outputs text to a Web page:

PHP:

echo "This is some text that'll be shown in a Web page...";

VBScript/ASP.NET:

Response.Write("This is some text that'll be shown in a Web page...");

Perl:

#!/usr/bin/perl

print "content-type: text/html nn";

print "This is some text that'll be shown in a Web page...";

Okay, now I am not going to say things like "well, obviously PHP is the easiest to understand" - as obviously, we all have different preferences, but what I can say is, that they all do the same thing. Which seems the most logical to you? In my opinion, the two most logical ones for me is PHP and VBScript/(ASP.NET).

Now it's up to you which one you want to go ahead with, experiment which one is best for you, after all, we all have dfferent tastes.

Good luck!
