Solid campaign on Google, should I just replicate it on MSN?

[dmorison]

I've got an established campaign running on Google AdWords, but i'm hesitant to simply replicate the campaign on MSN as I can't help thinking that given the current market share i'll just be advertising to the same people again; with the clicks that I will end up paying for through Google and MSN being the very same people.

Has anyone had any thoughts on this or have I missed any other threads covering this dilemma?

I'm certainly not going to dismiss AdCenter for all the search tie-ins that Microsoft will be able to channel via integration with IE7 / Vista etc, but in the short term i'm not sure what to do...

I've replicated my solid gold Adwords campaigns as a test, but I'm working on the assumption of that conversion rate may be lower (me being cautious based on some campaigns on YSM). I've had too few clicks/impressions to draw any conclusions yet.

I would ere on the side of caution for a while. If you read the thread about being overcharded $3000 for advertising it has definately made me a tad nervous about venturing too far into MSN until these bugs are resolved - could be very costly! I too have a large Adwords account, and after the recent algo change that caused so many good sites to lose their keywords thought I would investigate MSN. Have dipped my toe in the water - so far no probs, not as much traffic but conversion is good. I don't think you will get duplicated visitors, because I believe that people only tend to use one search engine and pretty much stick to it most of the time.:)
