This is a bizarre story from Search Engine Land.
It seems Yahoo has struck a deal with Google, to have the option to show google results and adverts in the Yahoo results, (again), a deal it already has in place with Microsoft owned Bing.
You might start to wonder what the point of Yahoo is these days, as they no longer seem to be an independent search engine, and have a variety of different products of varying quality such as Yahoo answers, and have closed previously popular products such as Geocities and the Yahoo Directory.
It looks like revenue is key, as they will be entitled to a share of Google advert revenue, but are Yahoo still considered a player in the modern search world? Interestingly, they will keep their deal with Bing, meaning you could see results from Bing and Google.
It looks like they have a way to go before any deal is finalised, with anti trust issues in the EU and India, plus requiring scrutiny from the American Department of Justice, which I'm guessing will be like our monopolies commission.
