Step-by-Step guide to Facebook Conversion Tracking

Step 1: Once you log in to your ‘Ads Manager’ tab, click on the Conversion Tracking button on the left side bar.

Step 2: Then click on the ‘Create Conversion Pixel’ tab to begin the process.

Step 3: You will be directed to this pop-up, which will ask you for a:

1. Name: An appropriate name will help you remember what you are tracking. (Example: Lead Generation – GATE Ad)

2. Category: This will help you decide the type of action that you want to track on your site. You can choose from the following:

1. Checkouts

2. Registrations

3. Leads

4. Key Page Views

5. Adds to Cart

6. Other Website Conversions

(For the purpose of this example, we have selected ‘Leads’).

Step 4: You will be able to see a pop-up window with a JavaScript code. This is the code that you will have to add to the page where the conversion will happen. This will let you track the conversions back to ads which you are running on Facebook.

The code should be placed on the page that a user will finally see when the transaction is complete.

Here is the tricky part. The code should not go on all pages. For that matter, it should not even go to the landing page of your product. The code should be placed on the page that a user will finally see when the transaction is complete.

For Example: If you want to track when students register for your GATE coaching, paste the code on the registration confirmation page/thank you page and not on the form that they need to submit.

How do you confirm that your conversion is working properly?

1. Check that the javascript snippet has been placed on the correct conversion page. Visit the page where the pixel has been embedded, right click and go to ‘View Page Source’ to find the pixel. The code should have the tag of the HTML. See image below.

2. Check that Facebook is receiving the conversion events from your website. Go to the conversion tracking tab in your Ads Manager account. There you will see a list of the conversion tracking pixels that you have created. If the conversion tracking pixel has been successfully implemented and a conversion event has been recorded, it will be reflected in the Pixel Status column. If the status shows active, it means that the page which contains the pixel has been viewed by users. If it shows inactive, it means that over the last 24 hours, the page with the pixel has not been viewed.

3.Later, when you  create your Facebook ad , you need to check the track conversions box under the campaign, pricing and schedule tab to enable tracking.

Facebook buys facial-recognition startup

Facebook Inc (FB.O) is paying $55 million to $60 million to buy Face.com, according to people familiar with the matter, acquiring the company that provides the facial-recognition technology used by the world’s largest social network to help users identify and tag photos.

The deal bolsters one of Facebook’s most popular features — the sharing and handling of photos — but the use of the startup’s

has spurred concerns about user privacy.

The No. 1 social network will pay cash and stock for Face.com, potentially paying as much as $60 million, two sources with knowledge of the deal said. Media reports in past weeks have pegged the transaction at $80 million to $100 million.

Neither Facebook nor Face.com disclosed terms of the deal, which is expected to close in coming weeks.

Facebook, which will acquire the technology and the employees of the 11-person Israeli company, said in a statement that the deal allows the company to bring a “long-time technology vendor in house.”

Face.com, which has raised nearly $5 million from investors including Russian Web search site Yandex (YNDX.O), launched its first product in 2009. The company makes standalone applications that consumers can use to help them identify photos of themselves and of their friends on Facebook, as well as providing the technology that Facebook has integrated into its service.

Facebook uses the technology to scan a user’s newly uploaded photos, compares faces in the snapshots with previous pictures, then tries to match faces and suggest name tags. When a match is found, Facebook alerts the person uploading the photos and invites them to “tag,” or identify, the person in the photo.

Responding to inquiries from U.S. and European privacy advocates, Facebook last year made it easier for users to opt out of its controversial facial-recognition technology for photographs posted on the website, an effort to address concerns that it had violated consumers’ privacy.

The deal is the latest in a string of acquisitions by Facebook in recent months, including the $1 billion acquisition of mobile photo-sharing service Instagram. U.S. antitrust regulators are undertaking an extended review of the Instagram deal, which Facebook expects to close by the end of the year.

Shares of Facebook, which continue to trade below the price at which they were offered during the initial public offering in May, closed Monday’s regular session up 4.7 percent at $31.41.

Social Gestures and the Social Web – Part I

FROM the Below Article was Copied from the website http://blog.engag.io/2012/04/15/social-gestures-and-the-social-web-part-i/

The Original Author – MR.  William Mougayar

Social Gesturing is at the heart of the social web. Those little signals have a small footprint but a large impact.

The crowd-sourced nature of social gestures adds up to a lot of value. After all, Facebook with all its might was mostly based and founded on 3 basic social gestures: liking, sharing and linking, each taking a fraction of a second to accomplish.

I’ve been thinking a lot about the hierarchy of social gestures in terms of value and potential.  And I came-up with the following way to organize them into a taxonomy where certain gestures are grouped with each other according to the objective they are meant to achieve and the purpose they target: People, Interests or Content.

The graph below is self-explanatory. The objective of social gesturing is to a) grab Attention, b) Express yourself, c) Curate interests (or content), d) develop Relationships, or e) Engage with people.

The most commonly used Social Gestures are Sharing, Linking and Liking when it comes to Content, and Following or Friending when it comes to People. But the area that holds the most promise is Engagement with People.

There is an ascending amount of time it takes to accomplish each gesture. If you look at the two extremes, Discussing something with someone is a lot more time-consuming than Clicking on content or Sharing it.

Personally, and for Engagio, I’m very interested in the gestures around Social Engagement. I think we’re just getting started in that segment, and I plan to cover more on that topic in Part II of this post.

In the meantime, what is your opinion on the following 3 questions:

• Are there other Social Gestures that you are seeing?

• Do you see new ones that are emerging?

• Which ones do you use the most?

Engagio: Recognize & Build Relationships On Social Network Easily

Engagio helps you to track your online conversations and allows you to develop meaningful relationships from them. In short, it is your tool to find quality relationships.

Pitched as ‘Your inbox for online conversations and relationships’, it is a tool much like Gmail, but is for managing your conversations in social networking sites and commenting systems. Engagio gives you visibility about the people behind these conversations and reveals their social identities profile. It saves you much time and allows you to connect with others in a much better and deeper way.

Although social media has many advantages, sometimes we fall short of managing our many relationships on social networking sites. With so many friends, family members, colleagues, classmates and relatives in our contacts list, we miss out on building quality relationships with people who matter. Engagio helps you to do that and more.

Engagio believes that commenting and conversations are strong social signals. They are stronger than likes, shares and links. Comments are implicit linkages about people. After all, you only care to comment on somebody’s post and take time to do it when you like that person or what s/he has to say. Like is easy, commenting takes time and thought. Engagio studies all that and more, and give you full visibility into the potential relationships behind your comments and conversations.

The service is frictionless and derives implicit data from your normal, everyday interactions. It does not matter whether your conversations are on social networks or inside your Engagio inbox, Engagio tracks them all. You connect to your social networks and Engagio starts to track, record, analyze and report on your interaction activity.

All you need to do is to signup from the entry page or jump to your inbox. You can easily track your conversations on Facebook, LinkedIn, Twitter, Google+, Disqus-enabled sites, Hacker news comments, Foursquare and more. This is a wonderful service for everybody who wishes to build up on great relationships without putting in much time and effort.

Mobile Trading

The Procyon Holdings (PROHD) name is expanding again as we push out into another development area — the Android framework. When I abandoned my BlackBerry, the choice to move to the Android platform was an easy decision. Market saturation, the development community, and fluidity between devices make this platform shine.

I’ve been having a few end user problems with the current iteration of our trading website. First, the native Android Gingerbread browser lacks SVG support, an issue that has bewildered me since I read about it. I can solve this issue by using another browser such as Opera, but I would like to use the native one.

Also working with a HTML + Ajax website on a device with a touch interface feels like you are not getting the full user experience. I want to scroll down lists with my finder, click and hold to expose options, and speed around menus.

Mobile Architecture

We had to expand our design and create a few new pieces to get data to the mobile world. New items include the creation of a daemon to simply database population, exposing data via XML, and working with an existing library to enable Push notifications.

Information Flow

The Daemon runs on our server, periodically pulls transactions from the Eve API, and places that information in our wallet table.

Our previous design was that you would have to hit the transactions webpage and it would trigger an update. Getting a page to refresh on a desktop connected via broadband versus a mobile phone is quite the different experience.

Android has a framework called C2DM(Android Cloud to Device Messaging) which enables you to send lightweight push notifications to devices.

Our vision is that when a sell order clears, a large/special sale has occurred, or a significant milestone has been reached, we send a notice. This will be visible on phone’s Status Notification Bar and cause me to act if deemed important. I have been forgetting to buy or trade a particular item after the sell orders have cleared. Forget things — loose profit.

Getting data out of our database required the creation of a webservice to produce XML output from our wallet table.

Here is an example of the sale of one item in our XML feed:

<?xml version="1.0"?>  
<TransactionList>  
<Transaction>  
<transactionDateTime>2012-04-19 06:21:04</transactionDateTime>  
<typeID>21096</typeID>  
<typeName>Cynosural Field Generator I</typeName>  
<quantity>1</quantity>  
<price>1948939.91</price>  
<profit>147803</profit>  
<stationName>STATION</stationName>  
<icon>21096_32.png</icon>  
</Transaction>  
</TransactionList>

Alpha Screenshot

This screenshot is our first proof of concept. We’re able to get information from an XML feed, display it, and get/cache images from the Eve image server. Major credit goes to my trading and corporation partner James, who has been doing the development work and educating me on the Android framework.

There is a lot we want to do with the mobile version. Menus, tabs, charts, reports, and the ability to add items to a shopping cart/wish list are all things on the drawing board.

Future Collaboration

This project is our first exposure to the Android framework and after the initial learning curve, we might perhaps coolabrate with the Aideron Robotics team on Aura. So maybe some of our trading mechanics will make their way into the Aura application.

Getting the Distance between Locations using Google Maps API

Modifying my post on drawing directions in a MapView using Google's API, I have come up with a solution to get the distance between two locations. Considering the same example I modified getDirections() to the method given below which returns distance as a string in kms(or meters).

public String getDistance(double lat1, double lon1, double lat2, double lon2) {
	String result_in_kms = "";
	String url = "http://maps.google.com/maps/api/directions/xml?origin=" + lat1 + "," + lon1 + "&destination=" + lat2 + "," + lon2 + "&sensor=false&units=metric";
	String tag[] = {"text"};
	HttpResponse response = null;
	try {
		HttpClient httpClient = new DefaultHttpClient();
		HttpContext localContext = new BasicHttpContext();
		HttpPost httpPost = new HttpPost(url);
		response = httpClient.execute(httpPost, localContext);
		InputStream is = response.getEntity().getContent();
		DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
		Document doc = builder.parse(is);
		if (doc != null) {
			NodeList nl;
			ArrayList args = new ArrayList();
			for (String s : tag) {
				nl = doc.getElementsByTagName(s);
				if (nl.getLength() > 0) {
					Node node = nl.item(nl.getLength() - 1);
					args.add(node.getTextContent());
				} else {
					args.add(" - ");
				}
			}
			result_in_kms = String.format("%s", args.get(0));
		}
	} catch (Exception e) {
		e.printStackTrace();
	}
	return result_in_kms;
}

How to get more page views for your blog

“What makes a blog popular? What drives page views?” These are the questions that we’ve been trying to answer over the last few weeks. We were on a mission to dig into the data and analyze the strongest parameters that influence the flow of visitors to WordPress.com blogs.

Out of the 30+ million blogs on WordPress.com, we randomly selected a sample of almost 100,000 blogs to perform a regression analysis. Here are our findings, together with a few recommendations. We hope that this provides some new information, and kudos to you in case you’ve already incorporated these tips into your blog – the data suggests that you’re on the right track. Keep it up!

Make your blog easy to follow – It almost sounds obvious, but the simplest way to build more awareness is to make it easier to do so. Make sure that you have the follow widget as visible as possible. If your readers receive a notification every time you post, or see your post in their reader, there is a much higher chance that they will revisit your blog.

Comments, Comments, Comments – The most successful blogs, we found, created and encouraged a dialogue with their readers. The best way to make people more engaged with your writing is for you to engage back and start a conversation. In your posts, encourage people to comment. Also, make sure that you reply to people’s comments and continue the dialogue. This back and forth conversation is a significant driver of page views; holding all else equal, every additional comment can potentially drive up to 18 incremental page views! You can start by simply asking follow-up questions at the end of each post: ”have you ever done X?”; “do you think Y is acceptable?”. You can read some more thoughts on how to build your audience  and how to get more comments.

Post Frequently and Regularly – Your readers want to know that you are there for them and that you are “on it”. If you post frequently and regularly and have enabled the follow feature as we mentioned above, checking your blog could become a daily routine for your readers. Even if it’s a short post, write something new as frequently as possible, and at regular intervals. (The Daily Post can help with ideas, as can the advice on how to get more traffic)

While these three tips were shown to be the most important drivers of page views in our analysis, you might consider other parameters, which we found as having a partially significant effect: syndicating your post to Twitter and Facebook (using Publicize), for example, could lead to additional page views.

Happy blogging!

Google to bring cheap Android tablets

The internet giant is reportedly set to launch a sub-Rs 10,000 tablet later this year.

Google has said that it will focus more on lower end tablets.

“There’s been a lot of success on some lower-priced tablets that run Android, maybe not the full Google version of Android, but we definitely believe that there is going to be a lot of success at the lower end of the market. It’s definitely an area we think is important and we’re quite focused on,” Larry Page, Google’s chief executive officer, was reported as saying.

Currently, there are a lot of cheap Android tablets in the market but these are mostly from lesser known manufacturers.

Google’s direct involvement in low cost Android tablets could be revolutionary. In fact, the online giant is reportedly set to launch a sub $200 (Rs 10,000) device this year itself. The tablet is said to have a 7 inch display with Android 4.0 operating system, a quad core processor, and WiFi for internet access.

Social Media Integration

Spotify & Social Media

Spotify music applications offer easy integration with a large variety of different, popular social media channels. With their user-friendly applications, integrating your music lifestyle into your previously established social media channels is fairly simple. Such social media channels that your Spotify application can integrate with are Facebook, Twitter, YouTube, and Flickr. As of this year, Spotify was completely redesigned in order to fully and completely integrate into both Facebook and Twitter accounts. The new application also has fully functioning/interactive applications, embedded into its database structure, such as last.fm, billboard.com, and Sounddrop.

Some of the key features of this fully-integrated platform offer sharing and tracking functions with your automatically-synchronized social media friends. Such functions include tracking what your friends are listening to, discovering  what sort of music and playlists are “trending”, as well as even  collaborating on shared playlists with other friends or users. These social media integration features have become such a vital part of this new social experience (i.e. Spotify) that new users are required to have a Facebook or Twitter account in order to complete registration of the service.

Last but not least, this marriage between Spotify and Facebook has also brought upon a little reverse-integration to the pairing. This reverse-integration comes from the recent addition and invention of a fully-functioning Spotify music application embedded on the Facebook website server.

Explore the REST API

I have had the pleasure of working with the WordPress.com REST API over the past few weeks and am very excited to start “dogfooding” this resource everywhere I can.

One cool feature is that all the endpoints are self-documenting. In fact, the documentation for the REST API is built by the API itself! With this information we were able to build a console to help debug and explore the various resources that are now available through the new API. So let me introduce you to the new REST console for WordPress.com.

A word of caution: the console is only available when you are logged into WordPress.com and is hooked up to the live system, so be careful with your POST requests!

At its simplest you can supply the method, path, query, and body for the resource you wish to examine (it’s pre-populated with /me). Press “Submit” to see the response status for your request and an expandable JSON object that you can explore. All links listed under meta are active, so click one to make another request.

To get a better idea of what kind of parameters a request can take, select it under the “Reference” section. It will then provide an interface with some contextual help to let you know which path, query, and body parameters it accepts, what each of those parameters are for, and a field for you to provide the value.

Iran Offers ‘Dialogue With Respect’ With U.S.

TEHRAN — After the icy mutual hostility of the Bush era, President Mahmoud Ahmadinejad of Iran on Tuesday made a conditional offer of dialogue to the Obama administration, saying Tehran was ready for “talks based on mutual respect and in a fair atmosphere.”

Hasan Sarbakhshian/Associated Press

Mr. Ahmadinejad spoke at a rally on Tuesday in Tehran marking the 30th anniversary of the Islamic revolution in 1979.

But he coupled the offer with an attack on former President Bush, calling for him to be “tried and punished” for his policies and actions in the Middle East and the Persian Gulf region.

Mr. Ahmadinejad’s remarks came in a televised address to a rally marking the 30th anniversary of the Islamic revolution in 1979 which deposed Shah Mohammed Reza Pahlavi, ended the close relationship between Washington and Tehran, and replaced it with decades of confrontation that culminated in former President Bush’s description of Iran as part of an “axis of evil.”

Since the inauguration of President Obama last month, however, Washington has sounded a more conciliatory tone, despite profound differences over Iran’s nuclear program and its support for political groups in the Middle East that the United States considers to be terrorists.

“The new U.S. administration has said that it wants change and it wants to hold talks with Iran,” President Ahmadinejad said.

“It is clear that change should be fundamental, not tactical, and our people welcome real changes,” he said. “Our nation is ready to hold talks based on mutual respect and in a fair atmosphere.”

Mr. Ahmadinejad went on to say that Iran could cooperate with the United States to uproot terrorism in the region. “The Iranian nation is the biggest victim of terrorism,” he said.

But he referred to former President Bush as one of reasons for insecurity in the region and said, “Bush and his allies should be tried and punished.”

“If you really want to uproot terrorism, let’s cooperate to find the initiators of the recent wars in the Middle East and the Persian Gulf region, try them and punish them,” he said.

His comments follow a series of overtures from Washington and seemed to move away from an earlier call by Mr. Ahmadinejad for the United States to apologize for actions in the relationship with Iran dating back 60 years.

Shortly after his inauguration, Mr. Obama told the Arabic-language television station Al Arabiya that “if countries like Iran are willing to unclench their fist, they will find an extended hand from us.”

Referring to Iran on Monday, Mr. Obama said at a news conference that he was “looking at areas where we can have constructive dialogue, where we can directly engage with them.”

“My expectation,” he said, “is that in the coming months we will be looking for openings that can be created where we can start sitting across the table face to face.”

Last weekend, Vice President Joseph R. Biden Jr. indicated at a security conference in Munich, Germany, that the United States would take a nuanced approach toward Iran. He suggested that the administration was willing to be more conciliatory than Mr. Bush had been, but also to continue his tough policies if necessary.

“We are willing to talk to Iran,” Mr. Biden said, but quickly tacked back to a refrain common during the last years of the Bush presidency, offering Iran’s leader a choice: “Continue down your current course and there will be pressure and isolation; abandon the illicit nuclear program and your support for terrorism, and there will be meaningful incentives.”

Many western nations, including the United States, reject Iran’s insistence that its nuclear program is designed solely for generating energy, suspecting that it is no more than a screen for a nuclear weapons program what would upset the regional power balance and potentially threaten Israel.

Washington also objects to Iran’s close ties to militant Islamic groups such as Hezbollah in Lebanon and Hamas in Gaza.

Mr. Ahmadinejad’s choice of the 30th anniversary of the Islamic revolution seemed particularly significant. The United States had been a close supporter of the shah, but after his fall, radical students stormed the American Embassy in Tehran and held 52 Americans hostage for 444 days. Washington broke off diplomatic relations with Tehran in 1980.

Mr. Ahmadinejad’s comments came two days after a former Iranian president, Mohammad Khatami — a reformist politician who advocated more détente with the West — announced that he would challenge Mr. Ahmadinejad in presidential elections next June.

Mr. Khatami, who won an overwhelming victory in 1999 and was president until 2005, was elected on promises to grant greater political and social freedom and improve foreign relations.

Mr. Ahmadinejad’s presidency, by contrast, has been marked by economic mismanagement, surging inflation and international isolation.
