In my last post about social network advertising, I spoke about reasons why social network advertising is a rapidly growing trend in online marketing tactics. Today, in this follow-up to part 1, I will be delving into the nuts and bolts of making the most of your social network advertising.

As tradition would have it, Facebook’s for college students and LinkedIn’s for professionals.  But what about mothers?  Yes, mothers can of course be both college students and professionals, but in any case, there’s CafeMom, and for CafeMom, there’s $5 million – the social networking site just had a successful round of funding.

Targeted content has grown in importance to advertisers, with content-specific “synthetic channels” offering better returns through the more effective placement of their advertisements.

The rise of the social network has caused the rise of other, perhaps predictable, things: copycat networks; and investor curiosity. Blame MySpace and Facebook. Blame (or congratulate) Hi5, known, apparently, everywhere but the US, for extracting $20 million out of venture capitalists.

Most PPC Marketers would probably send traffic direct to the Affiliate Marketing/CPA (cost per acquistion/action) offers landing page. But here’s an idea, build a niche community, like the folks at newly launched Boomj.com are doing.

In some dirty industries there are parallel markets/messages/ideas that have similar business models, but are loved and marketed as though they are pure and do nothing but improve the world.

Earlier, we reported on Boomj, a niche social network aimed at a subset of younger Baby Boomers. Niche social networks are popping up more often and growing at a nice pace.

There has been some useful posts of late that discuss the pracitical methods to get started at developing a new site or blog specifically for affiliate marketing. In particular Aaron Wall discusses practical tips for starting a new site and Dosh Dosh looks at choosing the right blog niche.

Results from a recent iProspect study outline the specific behaviors of users visiting the most popular social networking sites. Among other items, the study finds that marketers should spend more time and resources investing in sites that operate within a relevant niche to their product than they have in the past.
