If you’re not already testing out the Yahoo-Bing Paid Search channel, you may want to start thinking about it….Efficient Frontier launched a report this week in regards to the Revenue per Click (RPC) gains that the Yahoo-Bing transition is making on Google, most recently in Q4 2010. Note the chart that shows the 7 Day RPC average of both channels at the end of 2010. So is it time to add Yahoo-Bing to your marketing strategy?? It’s something to think about and consider if you are playing in the Google PPC game, or you are not ready to play with Google and want to test out PPC with a smaller market share.

Well, it was probably only a matter of time that Twitter would pick a big time suitor. And Twitter couldn’t just pick one, so they decided to go with two.

Both Google and Bing will start indexing “tweets” from public Twitter profiles in their search results. To date, tweets were not indexed by either search engine. But given the micro-blogging site’s current popularity, it was time for Twitter to test the dating pool.

If you have been following Twitter’s rise of success (50 billion tweets and counting), what it gained in popularity it lacked in revenue generation. While Twitter has received millions in venture capital, it has not been able to monetize its business model. The current partnership with Bing and Google looks to be the start, even though Twitter’s CEO Evan Williams denies this as the driver.

So what does the future hold for these new partnerships? We will just have to wait until after dessert is served.
