So you are passionate about a particular subject and you want to take your passion online. At this point you may not know where to start and this is where I hope I can help you. After all you deserve to share your passion with others and they will benefit from it also.

The key to building any website is to build it with your visitor in mind. What can you truly do for them that will add value to their experience when visiting your site? Let's take for example that you enjoy building model planes. The first place you are going to visit is the online forums.

The reason I choose forums is because this is where conversations take place relative to any given topic. This will give you a measure of interest. The first step is to see how up to date the forum is and secondly how many posts it receives per day. Additionally how many people respond to those posts on any given day?

Obviously the more the better, the more interest the better for you. The next thing you are going to look for is, what are the questions being asked and can you engage in the conversation and offer solutions. If this is the case your next task is to look for keywords. What keywords do people use to seek out solutions for their needs?

The next thing to do is look for a keyword tool. I am going to use Google's keyword tool for this example. Keyword tools by the way are not by any standard of the imagination an exact science. They give you a rough guide as to how many times a given keyword is searched. So do not think that the numbers you get are exact.

Your task right now is to develop a list of keywords.

Once you have this list you are now going to look at the level of competition. Starting out we do not want too much competition but remember competition is good as it means there is money to be made in that market.

We at this point are just looking for cheaper ways to enter the market. To do this enter your keyword into the search box in quotes. Then check how many websites are coming up for that keyword. If it is in the millions that is not good if it is in the thousands then that is great.

You will now be refining your list based on competition. Once the list is completely refined you will now have the general structure of your site. These keywords will make up individual web pages.

To conclude this is how to lay the foundation then once you have these keywords you will be ready to structure each of the pages on your site using each individual keyword with content relative to that. To learn how to put all this together select any of the links provided.

Reusing pieces of HTML code is a common way of making web sites (or web applications) more consistent, reliable, and more manageable. Even a small web site consisting of perhaps 20 or 30 web pages can benefit from reusing code for header and footer sections, for example. If the same header or footer is used across all the pages on the site, it makes sense to put the header and footer code in separate files, and then call those files to insert their contents where required.

PHP offers two statements that can be used for inserted the contents of one file inside another: include() and require(). These two statements are virtually identical, with the only real difference being that if require() fails, it gives a fatal error, whereas if include() fails it just gives a warning. For this reason I tend to use the include() statement as it just seems slightly more friendly.

So, to include the contents of a file called header.inc inside a web page called index.php, you would just need to insert the following line of code (wrapped in PHP opening and closing tags) inside index.php.

Include 'header.inc';

As PHP takes no notice of the extension used for the included file, you can use whatever extension you want to. Be careful though, if you put passwords inside an include file with a .inc extension, they will be visible. You can get around this by putting include files that contain sensitive information outside the document tree to prevent people from browsing to them.

In Part 2 we'll look at the use of functions when developing web sites and applications.

Many business owners or ordinary individuals consider building a website so as to give themselves a presence online. In the event you are considering building a site you might want to go online to visit some sites to get a few ideas first.

A website can add credibility to your business. These days many folks jump online in order to research products and services. Having a website will enable prospective clients find out more about your business. This will also help you to present your products and services in a more detailed fashion.

The key to building a successful website lies within understanding what the web is all about. The internet in its former years was called the information super highway. The reason why people use the internet is to gather information for multiple reasons.

What is needed is to understand how people search for information online. What keywords they use and how best to get your website in front of their eyes. So while they may not search for your particular product or service you may find relative terms that you can use that would be relevant.

Once you do this you then need to consider constructing your web pages so that they are both relevant to the individual searching and relevant to the search engines.

This way your web pages will get indexed and ranked for your chosen keywords sooner rather than later. This will enable your site to get free traffic and having your site found in the search engines will also add further credibility.

To conclude the main reason any business considers building a website is to enable them to reach a broader range of customers and as a result increase their business. So when building your website understand the fundamentals and build it with the customer and search engines in mind.
