Ok - so you have your niche, advertiser, and site you and you are ready to start blogging. Is it necessary to make your blog look like your advertisers page? Does it help?
If you make your site/page look too much like the advertiser that would not be a good thing. While you might get more conversions, it's doubtful the advertiser would be real happy with the imitation. It would depend on the advertiser but you have to be careful when it comes to things like that. - Megan
No, if fact, the owner of the original site could start problems for you, which means you'd be wasting your time making it.
