People are starting to be socialised to this with adwords pages getting more to the point, and left side sites having lots of hullaballo, reciprocal links and text padding which got them there in the first place.
Of course your adwords landing page should be a "selling" page, taking into account the higher qualification of adwords clickers.
In addition having you company name or brand in both places gives you some great branding for that search page. How could a serious buyer ignore you?
