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.

Functions are used to perform a well defined task that is normally repeated at various places within a web site, web application, or other software application. The function sometimes needs certain information before performing its task, and sometimes returns a value to the calling page or program.

An example of how to use a simple function in PHP:

 function showMessage() {
echo "{$_SESSION["message"]}"; }

The above example shows a very simple function that displays the contents of a session variable called 'message'. The idea being that while a user is using a web site, etc, various messages are generated and stored in the 'message' session variable. Whenever the showMessage function is called, the contents of the session variable are displayed. So, for example, when the user logs on, you could display a message saying that they have done so. Likewise, when they log off, a different message could be displayed.

Calling a function

To call the showMessage function, you would just need to include the line:

showMessage()

in the web page (wrapped in php tags to distinguish it from normall HTML).

Passing values to a function

Often, a function requires one or more input values in order to perform its task. For example, take the following example that takes two numbers as input, and adds them together. The result is then returned to the calling web page or program.

function addNumbers($number1,$number2) {
$answer = $number1 + $number2;
return $answer; }

In the calling program we would have something similar to the following:

$number1 = "5";
$number2 = "6";
$sumOfNumbers = addNumbers($number1,$number2);
echo "$sumOfNumbers";

Obviously, in a real program you would not have the numbers hardcoded like this, but they would be obtained from user input or by some other means. Notice also that although the name of the returned variable is $answer, the calling program makes no reference to that. We could, if we wanted to, change the calling program to:

$answer = addNumbers($number1,$number2);
echo "$answer";

which might make things slightly easier to understand.

Not every site needs a site map, they can certainly be a good idea. Site maps provide a dual purpose: They provide search engine spiders easy access to all of your site pages and they provide site visitors easy access to all of your site pages. The difference is that search engines and visitors access your site map differently and therefore there are different methods that need to be applied to creating site map(s) that are friendly for both engines and search spiders.

Small sites typically don't need a site map so long as all pages are linked in the main navigation. Once you get into main and sub-navigation menu's then site maps are helpful in allowing search engines and visitors to quickly find anything they are looking for within just a couple of clicks. A single site map can be used for both purposes or multiple site maps can be created. Here we'll address creating site maps for spiders and humans separately.

Site Map For Spiders

.xml file

An .xml document should be added to your site's root directory containing links to all site pages. This .xml file should then be referenced should be compiled and placed into a proper .xml document which should be uploaded into the root directory.

Robots.txt file

With your .xml site map file in place you must then make it accessible to search spiders. Reference the site map in your robots.txt file by adding a line for sitemap: URL (example: sitemap: http://www.polepositionmarketing.com/sitemap.xml)

Keep current

Be sure that your .xml file is updated and uploaded frequently, or at least as often as pages are added or removed from your site. Large sites should implement an automated site map update monthly or even weekly or daily.

Site Map For Visitors

Navigation links

A site map designed for human visitors is just like any other website page. Link to the site map page should be included in the primary navigation or the site's global footer. Visitors should be able to find this link without too much searching.

Additional page links

Site map should also be linked from various pages within the site such as Help pages and your custom 404-redirect page. This helps point visitors to the site map as a quick and easy means to find what they need.

Overview

It's helpful to provide a short overview paragraph at the top of your site map page. This can be a nice introduction should someone land on this page directly from a search engine or elsewhere.

Heading and layout

The layout of the site map should present a clear visual hierarchal structure or your website. Both headings and sub-headings should be used above properly grouped links.

Text links & descriptions

Site map should primarily use textual links and page should not be cluttered with images or other distractions. It is also a good idea to provide an additional short description (provided there is room) for each link that allows the visitor to better understand where each link will take them.

Keep current

Be sure that your site map is updated and uploaded frequently, or at least as often as pages are added or removed from your site.

As I said above, not every site needs a site map. But those that do should be sure that the site map(s) they create are actually benefiting them. And the best way to do that is to make sure your site maps provide maximum usability for visitors and search engine spiders.
