Was wondering if anyone knows the basics of optimizing MSN content adgroups. What I mean, is... For adwords content network, you should create a large number of adgroups with very tightly focused variations of a single keyword theme within each. This is because google just looks at your adgroup, and for content ads, determines the overall theme of your keywords within an adgroup, and then matches them to a page. Keywords that aren't closely related seem to confuse it.
So, if I am targeting the MSN content network, should I use a similar strategy, or is it more keyword related than theme related. If it is keyword related, I would assume that the more keywords, variations of keywords and long tail words the better. But I have no idea, and there is no documentation outlining the logic of how adcenter ads are assigned to the content network.
If a page is about Discount Red Widgets in Phoenix Arizona, do I have just as good of a chance being on that page with a single keyword "Red Widget", or do I need "discount red widgets" or "discount widgets" or the whole long-tail "discount red widgets phoenix arizona"? And, would it make any difference if they were all in the same adgroup or not?
