Social networks are plenty and in past few years they have grown both horizontally from dynamic user groups to platforms and vertically from social networks for gays and lesbians to invitation only groups for social elites.
Social networks are hugely succesful in India too. According to latest data from camScore indian social networks have grown 50 % in the year 2007-08. Moreover majority of web users are now social networkers.

But despite this phenomenal adaptation of SNs idea , social networks are loosing more money then they make for their investors.
This post is my attempt to understand the whole social network monetisation problems and related issues.
Social networks are used as marketing and branding media and make money through advertising same way as TV, Radio, Newspaper does. This way advertisiding drives the form and functions of social networks. Social networks have to cater needs of two different parties, the actual user, who want to use them as they wish to with minimum interference from anyone incling owners and advertiser who pay for runing the show and what users to behave in curtain way. This create a disconnect between interest of parties involved and there a contest going on between user and advertisers where social network trying to balance the needs of both parties.
Social network are new kind of media in advertising industry and do not enjoy same level acceptence and trust among media buyers as enjoyed by TV & newspapers. They are yet to prove their effectiveness and metrics used to evaluate thier effectiveness are evolving.
Other challenges involoved in monetizsing are related to very nature of social network. For exampl most of the network rely on user generated content where social network have very limited freedom to play with content. Most of the user activities are action oriented like writing on wall, poking friends, sending sms and hence provided little space for text/display adversting model. Users are agnostic to any significant changes in social network structure and forms done to suit the needs and requirements of advertisers. Attempts to sell/use user information to third party resulted in backlashs and there is increasing awareness among users about privacy related issues. Many user privacy watchdogs are seeking change in privacy policies of social networks.
Below is more detailed analysis of two major issues related to monetisation of Social networks.
1. Low CPM or Unsuitable metrics – CPM may not be the best indicator of social network analysis
Lookery, an ad network specializing in social media, offers display ads on MySpace, Facebook, and Bebo for only 13 cents per thousand times the ad is served (CPM); Yahoo’s average CPM is estimated at $13. Video ads on MySpace reportedly fetch just $25 per thousand showings; CBS charges $50 on affiliated sites, NBC as much as $75. (Source)
Next question will be is why SN have low CPM . The reason is that most social network reply soley on advertising revenue.
Regardless of the model (CPM, CPC, CPA), advertisers value three key measures: reach, frequency, and targeting. Many social media sites certainly score high on reach and frequency, but how do they fare on targeting? Targeting is key, because it determines the CPM rates advertisers are willing to pay. And CPM rates vary very widely: from $16-20 for TripAdvisor to $0.10 for Facebook and MySpace. See, for example, this media plan. (Source)
There is another dimention to low CPM for social networks which is quite counterintutive.
The assumption is that if users are worth money, then more users are worth more money. Theoretically, an infinite number of users are worth an infinite amount of money. It’s simply not true.
There is a point of diminishing returns in Web advertising. Enormous traffic creates a glut of inventory, which inevitably drives the value of ads down. The most highly valued inventory on the Web is branded, high-quality media content. It’s valuable because the content projects value onto the advertiser. When Target advertises on MTV.com, the brand benefits from MTV’s youth-oriented content, giving the brand a youthful shine. In contrast, utility inventory lacks the compelling context that advertisers need to help build identity and image, and in many cases may include negative images. The result is that advertisers have no cause to align their brands with products like Social Networks. Unlimited inventory and negative brand association is a perfect storm for low CPMs.(Source)

2. User behaviour
Both social network & advertsier would like to use datamining techniews to target there advertsing to improve their CPM . But this leds to problems related to privacy fo user information . User behaviour give different challenges to social network. On social networks, people are primarily concerned with communicating with their friends, not looking to buy items or services. Moreover when marketers try to shake things up, users don’t take kindly to major changes. There are issues related to trust and privacy of user infomation and this lack of trust is mutual.
the fundamental problem that social networks face when trying to monetize through an advertising-driven business model is the lack of trust. To be more explicit, while brand advertisers have historically trusted people as consumers, they do not trust them in the new role of producer (e.g. uncontrollable content). Likewise, people who are armed with the power of interactivity are also demonstrating that they are increasingly distrustful of brand advertisers (e.g. ad-skipping).(Source)
I come across few exellent presentations related to subject. Here are two of them
In the next post I will look for solutions that are been tried to resolve problems mentions above and will do some analysis on how successful are they in generating revenue for companies. I would also like to cover indian social networks are trying to resolve monetization conundrum

Update : There is change of priorities in professional and career side and due lack of time to research I am finishing this article here.
