Indian election 2009

NEW DELHI: The Congress' improved rakings at the hustings tell the story of a resurgent party. Unlike its political rivals, the Congress got both
its plot and script right—whether it was the emphasis on rural India, eschewing the idea of a national alliance, or the decision to go it alone in the Hindi heartland, where the Congress was practically sidelined.

In the run-up to the elections, as early as January, the Congress Working Committee decided to go it alone at the national level. Alliances were to be at the state level, a move that had angered parties that had constituted the UPA.

The constant sniping at the heels by its allies, for being left to fend on their own at the national level, was often interpreted as a move that would hurt the Congress electorally.

However, the reassertion of the party as an entity outside of the UPA, which it essentially described as an alliance of governance, has worked to its favour. That the Congress managed to hold its own and even improved its showing across the country only served to stress that the decision by the Congress leadership to contest by itself helped to script the resurrection story.

Even a bigger gamble was the decision of ‘going solo’ in the Hindi heartland states of Uttar Pradesh and Bihar. The Congress had been virtually sidelined in the two politically important states.

Despite the scepticism over the efficacy of the decision taken so late in the day, just a month before the election, and the difficulties the Congress faced in fielding candidates, the gamble paid off. Though both these states had once been traditional bastions of the Congress, the party had been practically sidelined. It is in the hastily put together ‘going solo’ script, that the revival story of the Congress is best told.

In Uttar Pradesh, which was being viewed as the BSP’s stronghold, the Congress has succeeded in forcing a rupture in Mayawati’s social engineering project. Sections of the upper caste that had veered towards the BSP are now gravitating back to the Congress. Muslims, a key force in the state’s electoral politics, too have been drawn back to the Congress.

Though the party can't claim to have reclaimed the Muslim vote in full measure, it is now a claimant just like the SP and the BSP. The plan to hit the hustings on its own has helped the Congress build on its existing and loyal base. The mindset in Uttar Pradesh has traditionally been in favour of the Nehru-Gandhi family and the Congress, and the party’s attempt to reassert its place on the state political stage has been rewarded by the people.

In adjoining Bihar, the story of the Congress’ resuscitation may not have translated into wins as it did in Uttar Pradesh. However, the party has increased its vote share. That could script the beginning of a revival story in the state, where the Congress could reclaim its traditional vote banks over a period of time. A resurgence on the lines of Uttar Pradesh may then only be a matter of time and not an impossibility.

The impact of the ‘going solo’ move was felt beyond these two states. The Congress was able to build on its latent vote base, even in states that were BJP strongholds, such as Madhya Pradesh. Despite as many as seven factions within the party’s state unit, the Congress was able to improve its tally, indicating that its traditional support base was slowly consolidating.

If the party’s political gambles paid off, its decision to focus on rural India helped reduce the risk considerably. The focus proved to be a powerful counterpoint to the adverse impact of price rise and unemployment.

Given that 70% of rural India consumes what it produces, the focus on efforts such as the farm loan waiver and national rural employment scheme helped the party gain depth.

It helped the Congress project itself not just as a party concerned with fighting immediate issues, but one that was looking at the long term. It reinforced the message the Congress strategists had been aiming to put across: the story of India’s resurgence lay in rural India, and that the party was well-seized of this idea.

Email Universe

Since 1999 Christopher Knight has been helping publishers succeed with newsletter marketing. Using AdSense referrals, he was able to recommend relevant products and services to his vistors while increasing his revenue over 140%.
Case study : EmailUniverse.com and EzineArticles.com
Ezine.com

Business

At Email Universe, marketers can find a wealth of information about how to publish successful email newsletters. At Ezine Articles they can find a rich source of content: e-newsletter articles covering 320 different industries, from arts and entertainment to home-based businesses. Publisher Christopher Knight runs both sites, and even he is sometimes surprised by how much traffic they generate: "a quarter of a million visitors every day to Ezine Articles, and more than 9 million page views each month."

Approach
"AdSense referrals gave us a 142 percent increase in revenues last month on emailuniverse, without a dip in income from AdSense."

Christopher Knight
Publisher

To capitalize on this traffic, Knight runs Google AdSense contextual ads across his site. He tried other advertising networks, but found that Google was able to deliver more advertisers and more variety. "Google AdSense gives me more unique ads per page than any other program," he explains. "Because of the rich inventory of ads it delivers, AdSense helps me earn income on my site better than I ever could by recruiting advertisers on my own."

Knight also runs AdSense referrals, a feature that enables site publishers to increase their revenue while expanding their visitors’ awareness of useful products and services. AdSense let Knight select ads that directly matched up with his ever-changing content; On a page that offered advice on starting email marketing campaigns, for example, he selected ads from Constant Contact, an industry leader in email marketing. AdSense referrals have allowed Knight to add his own insights about his users and his content to select useful advertisements.

Knight has also become expert at trying different ad placements and formats to optimize his success with AdSense and AdSense referrals, using channels in AdSense to track which ads get the most clicks. "On Ezine Articles, we found that ads perform best in the center of an article, just above the body copy," he observes, adding that since the ads are so relevant to his site’s content, "the majority of visitors don’t even realize it’s an ad."

Knight has also tested conversion rates in relation to placement, and has learned to position the best-converting ads above the fold.

Results

Initially, Knight was concerned that adding AdSense referrals to his site might diminish his returns from AdSense contextual ads, reasoning that people might exit the site without clicking on the ads. By putting this question to the test, he found that AdSense referrals added incremental revenue without detracting from AdSense. "AdSense referrals gave us a 142 percent increase in revenues last month on emailuniverse, without a dip in income from AdSense," he reports.

Given that kind of return, Knight is quite satisfied with the income he’s earning from both AdSense for Content and AdSense Referrals. And as a publisher who’s always eager to experiment and optimize his results, he believes he’ll continue to earn more over time. "AdSense lets our employees focus on editorial and making our sites better," he says. "We can obsess about the user experience because we don’t have to obsess about ad revenues."

Medical Coding

Medical Coding.Net found greater clickthrough and conversion with Google.

Medical-Coding.net

Entrepreneur Darren Carter, M.D. created a company in 2001 to sell software and other products for medical coding and billing processes, an increasingly important task for medical practices of all kinds. His company, Medical Coding.Net, is today a wholly owned subsidiary of Provistas, Inc., which provides Medicare compliance solutions to hospital and physician-practice clients. Medical Coding.Net receives a qualified professional audience of about 500 unique visitors each day.

Challenge
"Every ad that shows is a complement to my sites, and I'm getting high-quality traffic."

Darren Carter, M.D.
Entrepreneur

"In my industry, people are out looking for a variety of services and products," says Dr. Carter. In order to grow his e-commerce business, his online marketing strategy now includes Google AdWords to drive traffic to Medical Coding.Net; Froogle to increase visibility and gain customers for his specialty software; and AdSense (AdWords ads on content pages). He intends to leverage this combination of all three Google programs in order to gain traffic, clicks and buyers.

Results

"AdWords sends qualified leads my way," says Dr. Carter. "We get cost-effective visibility that's tied to very specialized keyword searches through our AdWords program.” For those visitors "who don't find what they need from the products on my site,” he adds, "the AdSense program, which enables Google ads on other sites, seems to offer them what they need." says Dr. Carter. He also notes that enabling these "unobtrusive" ads "took only a few minutes to put up. It was very easy to add the code." The ads now appear for nearly 100 percent of the site's pages.

While he was initially concerned that ads on his discussion forums would not be well-targeted due to the dynamic nature of those pages, Dr. Carter says he is "very pleasantly surprised at how well targeted they are. "Every ad that shows is a complement to my site," he says, "and I'm getting high quality traffic." He also takes advantage of ad blocking, noting that even in this highly specialized arena there are enough suitable ads after he blocks direct competitors.

Regarding Froogle, Dr. Carter says, "This free merchant program is a great way to become visible for a specialized product category." He sends an XML feed for Froogle to upload whenever he has new pricing, sales promotions, or new products. "It's incredibly easy way for us to be branded in a big e-commerce channel, and we see customers who would not have found us otherwise."

For all of his efforts, Dr. Carter is seeing a healthy five-figure return on his advertising investment. He also reports that AdSense revenue more than offsets his AdWords expenditure: "In fact, we have reduced our overall ad budget," he says. What's more, he reports a consistent and healthy 3.6 percent clickthrough rate. Overall, Dr. Carter concludes that " All of Google advertising has had a very favorable impact on my business."

Teachnology

Business

TeAch-nology offers services and resources designed to support educators who want to effectively incorporate technology into their classrooms. The company provides a reservoir of online resources and delivers effective tools for designing instruction. At TeAch-nology.com, educators can find best practices information, as well as a variety of free classroom materials and support tools. A seasoned team, including pre-K to K-12 grade teachers, professors of higher education, leading educational consultants, small business consultants and experienced web designers, maintains TeAch-nology.com.

There’s no charge for accessing many of the resources found on TeAch-nology.com. Educators who want more in-depth content and resources can purchase memberships for a modest annual fee.

Approach
"The quality of the AdSense ads is superb. It's almost as if a specialist hand-picked ads for every page. The ads match our content so perfectly, it's amazing"

Paul McKee
Founder

Founder Paul McKee explains that he can offer the site as a free service due to advertising campaigns and sponsorships. For several years, TeAch-nology has relied on Google AdWords search-based advertising to help drive traffic to the site and encourage membership sales. The site now receives 3 million page views each month. "AdWords provides an unbeatable return on investment for us," says McKee.

McKee started investigating other ways to increase his income. He saw TeAch-nology’s ads showing up on other relevant education sites, and was impressed with how well his ads matched the content. "When we saw how relevant our ads were to users on other education sites, we decided to investigate use of contextual advertising ourselves on TeAch-nology," says McKee. In the fall of 2006, TeAch-nology began running Google AdSense ads throughout the site.

Results

It was easy to implement AdSense, McKee says, but what impressed him most was the relevance of the ads his users now see. "The quality of the AdSense ads is superb," says McKee. "It’s almost as if a specialist hand-picked ads for every page. The ads match our content so perfectly, it’s amazing."

In terms of revenue, McKee notes that AdSense ads outperform other forms of contextual advertising by 8 to 9 times. He notes that he’s "extremely satisfied" with AdSense, which now accounts for 50 percent of company revenue. Equally important, McKee says that filling his ad space through AdSense frees up efforts to sell memberships, another key source of revenue. "We don’t have a full-time ad sales team," McKee observes. "AdSense takes care of itself, allowing us to focus on running our business."

In all, McKee believes he’s found a powerful tool to make the most of the educational site he runs. "It’s vital to us to be able to continue offering a wealth of resources to educators at no charge," he says. "Without revenues from AdSense, that goal would be difficult if not impossible to achieve."
