Faculty Forum / Facebook offering e-retailers sales tracking tool

Facebook offering e-retailers sales tracking tool [/color]

Facebook will begin rolling out on Friday a new tool which will allow online retailers to track purchases by members of the social network who have viewed their ads.

The tool is the latest of the new advertising features Facebook is offering to convince marketers that steering advertising dollars to the company will deliver a payoff.

Facebook, with roughly 1 billion users, has faced a tough reception on Wall Street amid concerns about its slowing revenue growth.

"Measuring ad effectiveness and outcomes is absolutely crucial to all types of businesses and marketers," said David Baser, a product manager for Facebook's ads business who said the "conversion measurement" tool has been a top customer request for a long time.

The sales information that advertisers receive is anonymous, said Baser. "You would see the number of people who bought shoes," he said, using the example of an online shoe retailer. But marketers would not be able to get information that could identify the people, he added.

The conversion tool is specifically designed for so-called direct response marketers, such as online retailers and travel websites that advertise with the goal of drumming up immediate sales rather than for longer-term brand-building.

Such advertisers have long flocked to Google Inc's Web search engine, which can deliver ads to consumers at the exact moment they're looking for information on a particular product.

But some analysts say there is room for Facebook to make inroads if it can demonstrate results.

"The path to purchase" is not as direct on Facebook as it is on Google's search engine, said Debra Aho Williamson, an analyst with research firm eMarketer. But she said that providing information about customer sales conversion should help Facebook make a stronger case to online retailers.

"It lets marketers track the impact of a Facebook ad hours or days or even a week beyond when someone might have viewed the ad," said Williamson. "That allows marketers to understand the impact of the Facebook ad on the ultimate purchase."

Marketers will also have the option to aim their ads at segments of Facebook's audience with similar attributes to consumers that have responded well to a particular ad in the past, Baser said.

Online retailer, which has tested Facebook's new service, was able to reduce its cost per new customer acquisition by 39 percent when it served ads to consumers deemed most likely to convert, Facebook said. Facebook defines a conversion as anything from a completed sale, to a consumer taking another desired action on a website, such as registering for a newsletter.


Shares of Facebook, which were priced at $38 a share in its May initial public offering, closed Thursday's regular session at $22.17.

In recent months, Facebook has introduced a variety of new advertising capabilities and moved to broaden its appeal to various groups of advertisers.

Chief Operating Officer Sheryl Sandberg said in October that Facebook saw multi-billion revenue opportunities in each of four groups of advertisers: brand marketers, local businesses, app developers and direct response marketers.

Facebook does not disclose how much of its ad revenue, which totaled $1.09 billion in the third quarter, comes from each type of advertiser. Pivotal Research Group analyst Brian Wieser estimates that brand marketers and local businesses account for the bulk of Facebook's current advertising revenue.

Earlier this year, Facebook introduced a similar conversion measurement service for big brand advertisers, such as auto manufacturers, partnering with data mining firm Datalogix to help connect the dots between consumer spending at brick-and-mortar and Facebook ads.

And Facebook has rolled out new marketing tools for local businesses such as restaurants and coffee shops, including a revamped online coupon service and simplified advertising capabilities known as promoted posts.

The new conversion measurement tool is launching in testing mode, but will be fully available by the end of the month, Facebook .

PHP Tutorial
Part 2 - Displaying Information & Variables

Introduction :

In the last part of the tutorial I explained some of the advantages of PHP as a scripting language and showed you how to test your server for PHP. In this part I will show you the basics of showing information in the browser and how you can use variables to hold information.

Printing Text :
To output text in your PHP script is actually very simple. As with most other things in PHP, you can do it in a variety of different ways. The main one you will be using, though, is print. Print will allow you to output text, variables or a combination of the two so that they display on the screen.

The print statement is used in the following way:

print("Hello world!");

I will explain the above line:

print is the command and tells the script what to do. This is followed by the information to be printed, which is contained in the brackets. Because you are outputting text, the text is also enclosed instide quotation marks. Finally, as with nearly every line in a PHP script, it must end in a semicolon. You would, of course, have to enclose this in your standard PHP tags, making the following code:

print("Hello world!");

Which will display:

Hello world!
on the screen.

Use of Variables :
As with other programming languages, PHP allows you to define variables. In PHP there are several variable types, but the most common is called a String. It can hold text and numbers. All strings begin with a $ sign. To assign some text to a string you would use the following code:

$welcome_text = "Hello and welcome to my website.";

This is quite a simple line to understand, everything inside the quotation marks will be assigned to the string. You must remember a few rules about strings though:

Strings are case sensitive. so $Welcome_Text is not the same as $welcome_text
String names can contain letters, numbers and underscores but cannot begin with a number or underscore
When assigning numbers to strings you do not need to include the quotes so:

$user_id = 987
would be allowed.

Outputting Variables :

To display a variable on the screen uses exactly the same code as to display text but in a slightly different form. The following code would display your welcome text:

$welcome_text = "Hello and welcome to my website.";

As you can see, the only major difference is that you do not need the quotation marks if you are printing a variable.

Formatting Your Text :

Unfortunately, the output from your PHP programs is quite boring. Everything is just output in the browser's default font. It is very easy, though, to format your text using HTML. This is because, as PHP is a server side language, the code is executed before the page is sent to the browser. This means that only the resulting information from the script is sent, so in the example above the browser would just be sent the text:

Hello and welcome to my website.

This means, though, that you can include standard HTML markup in your scripts and strings. The only problem with this is that many HTML tags require the " sign. You may notice that this will clash with the quotation marks used to print your text. This means that you must tell the script which quotes should be used (the ones at the beginning and end of the output) and which ones should be ignored (the ones in the HTML code).

For this example I will change the text to the Arial font in red. The normal code for this would be:

<font face="Arial" color="#FF0000">

As you can see this code contains 4 quotation marks so would confuse the script. Because of this you must add a backslash before each quotation mark to make the PHP script ignore it. The code would change to:

<font face=\"Arial\" color=\"#FF0000\">

You can now include this in your print statement:

print("<font face=\"Arial\" color\"#FF0000\">Hello and welcome to my website.</font>");

which will make the browser display:

Hello and welcome to my website.
because it has only been sent the code:

<font face="Arial" color="#FF0000">Hello and welcome to my website.</font>

This does make it quite difficult to output HTML code into the browser but later in this tutorial I will show you another way of doing this which can make it a bit easier.

PHP Tutorial 1

Part 1 - Introduction


Up until recently, scripting on the internet was something which very few people even attempted, let alone mastered. Recently though, more and more people have been building their own websites and scripting languages have become more important. Because of this, scripting languages are becoming easier to learn and PHP is one of the easiest and most powerful yet.

What Is PHP?

PHP stands for Hypertext Preprocessor and is a server-side language. This means that the script is run on your web server, not on the user's browser, so you do not need to worry about compatibility issues. PHP is relatively new (compared to languages such as Perl (CGI) and Java) but is quickly becomming one of the most popular scripting languages on the internet.

Why PHP?

You may be wondering why you should choose PHP over other languages such as Perl or even why you should learn a scripting language at all. I will deal with learning scripting languages first. Learning a scripting language, or even understanding one, can open up huge new possibilities for your website. Although you can download pre-made scripts from sites like Hotscripts, these will often contain advertising for the author or will not do exactly what you want. With an understanding of a scripting language you can easily edit these scripts to do what you want, or even create your own scripts.

Using scripts on your website allows you to add many new 'interactive' features like feedback forms, guestbooks, message boards, counters and even more advanced features like portal systems, content management, advertising managers etc. With these sort of things on your website you will find that it gives a more professional image. As well as this, anyone wanting to work in the site development industry will find that it is much easier to get a job if they know a scripting language.

What Do I Need?

As mentioned earlier, PHP is a server-side scripting language. This means that, although your users will not need to install new software, you web host will need to have PHP set up on their server. It should be listed as part of your package but if you don't know if it is installed you can find out using the first script in this tutorial. If you server does not support PHP you can ask your web host to install it for you as it is free to download and install. If you need a low cost web host which supports PHP I would recommend HostRocket.

Writing PHP

Writing PHP on your computer is actually very simple. You don't need any specail software, except for a text editor (like Notepad in Windows). Run this and you are ready to write your first PHP script.

Declaring PHP

PHP scripts are always enclosed in between two PHP tags. This tells your server to parse the information between them as PHP. The three different forms are as follows:

PHP Code In Here
//* It also known as short tag

PHP Code In Here
//* We prefer his style

<script language="php">
PHP Code In Here

All of these work in exactly the same way but in this tutorial I will be using the first option (<? and ?>). There is no particular reason for this, though, and you can use either of the options. You must remember, though, to start and end your code with the same tag (you can't start with <? and end with </script> for example).

Your First Script

The first PHP script you will be writing is very basic. All it will do is print out all the information about PHP on your server. Type the following code into your text editor:


As you can see this actually just one line of code. It is a standard PHP function called phpinfo which will tell the server to print out a standard table of information giving you information on the setup of the server.

One other thing you should notice in this example is that the line ends in a semicolon. This is very important. As with many other scripting and programming languages nearly all lines are ended with a semicolon and if you miss it out you will get an error.

Finishing and Testing Your Script

Now you have finished your script save it as phpinfo.php and upload it to your server in the normal way. Now, using your browser, go the the URL of the script. If it has worked (and if PHP is installed on your server) you should get a huge page full of the information about PHP on your server.

If your script doesn't work and a blank page displays, you have either mistyped your code or your server does not support this function (although I have not yet found a server that does not). If, instead of a page being displayed, you are prompted to download the file, PHP is not installed on your server and you should either search for a new web host or ask your current host to install PHP.

Tutorial : HTML Multimedia

What is Multimedia?

Multimedia comes in many different formats. It can be almost anything you can hear or see like text, pictures, music, sound, videos, records, films, animations, and more. On the Internet you can often find multimedia elements embedded in web pages, and modern web browsers have support for a number of multimedia formats.

In this tutorial you will learn about different multimedia formats and how to use them in your web pages.

Browser Support
The first Internet browsers had support for text only, and even the text support was limited to a single font in a single color. Then came browsers with support for colors, fonts and text styles, and the support for pictures was added.

The support for sounds, animations and videos is handled in different ways by different browsers. Some elements can be handled inline, and some requires an extra helper program (a plug-in).

Multimedia File Formats  :

Multimedia elements (like sounds or videos) are stored in media files.
The most common way to discover the media type is to look at the file extension. When a browser sees the file extensions .htm or .html, it will assume that the file is an HTML page. The .xml extension indicates an XML file, and the .css extension indicates a style sheet. Picture formats are recognized by extensions like .gif and .jpg.

Multimedia elements also have their own file formats with different extensions like .swf, .wmv, .mp3, and .mp4.

Video File Formats :
   The MP4 format is the new and upcoming format for internet video. It is supported by YouTube, Flash players and HTML5.

Format        File         Description
AVI              .avi         The AVI (Audio Video Interleave) format was developed by Microsoft. The AVI format is supported by all   
                                      computers  running Windows, and by all the most popular web browsers. It is a very common format on   
                                      the Internet, but not always possible to play on non-Windows computers.

WMV   .wmv         The Windows Media format is developed by Microsoft. Windows Media is a common format on the Internet, but
                                      Windows Media movies cannot be played on non-Windows computer without an extra (free) component   
                                      Some later Windows Media movies cannot play at all on non-Windows computers because no player is

MPEG  .mpg .mpeg         The MPEG (Moving Pictures Expert Group) format is the most popular format on the Internet. It is cross-
                                      platform and supported by all the most popular web browsers.

QuickTime      .mov         The QuickTime format is developed by Apple. QuickTime is a common format on the Internet, but QuickTime   
                                      movies cannot be played on a Windows computer without an extra (free) component installed.

RealVideo     .rm .ram       The RealVideo format was developed for the Internet by Real Media. The format allows streaming of video
                                      (on-line video, Internet TV) with low bandwidths. Because of the low bandwidth priority, quality is often

Flash   .swf  .flv         The Flash (Shockwave) format was developed by Macromedia. The Shockwave format requires an extra
                                      component to play. But this component comes preinstalled with web browsers like Firefox and Internet
Mpeg-4   .mp4           Mpeg-4 (with H.264 video compression) is the new format for the internet. In fact, YouTube recommends using
                                      MP4. YouTube accepts multiple formats, and then converts them all to .flv or .mp4 for distribution. More and
                                      more online video publishers are moving to MP4 as the internet sharing format for both Flash players and
