What are the pros and cons of sending AdWords traffic to a Blogger (Blogspot) Landing Page as opposed to a site with many pages on its own domain?
You don't own the domain, it could be shut down. Instead build that blog but point links at your real landing site that you host and own. (Cue the dumb dumbs who will say incoming links don't matter now...)
LOL... incoming links I guess Im a dumb dumb... Even though most of my LP's, either mine or clients, have none and yet, still highly successful with great QS
You could try to change from Blogspot to Blogger Custom Domain using your own domain. I have try using blogger for landing page, and I always get a Great Score. Great score=Low CPC Success to you.
