I think a few people here would use blogger as a landing page, I know I've tried them and they do work but I'm not too sure people will want to give away the niches they're promoting.
The only drawback in using blogger as a landing page is that it usually has a crappy quality score with Adwords campaigns ..
haha, I just wanted to open a thread about this ! Last night I made one landing page on Blogger, well so called landing page. I've customized a layout, added a post with few keyword rich sentences, and iframed publisher's website. It doesn't look bad at all , just need to drive traffic for it. Adwords quality score doesn't worry me cause I can't advertise this site on Adwords anyway. Water4Gas
Hey, by all means you have nothing to lose. It's all free and what is needed is time to add the contents.
