To be honest, this can't really be called a landing page. A landing page tries to get one clear action from the visitor, be it opting in or buying something. When I clicked on your link I felt like I've been taken to an ecommerce store. With broad keywords like "spirulina" the majority of people are usually looking for more info on the subject rather than buying a bunch of pills from the first site they land on.

On top of that, I find your site very distracting, way too much going on and too many different fonts, colors, sizes and everything. This is probably supporting the bad bounce rate.

That's not good at all. The other way around would work though. Has to be your page and its content/ look

Broad keywords attract a broad range of traffic, people after information, images, news, etc. you need to do some proper keyword research and clean up the site. To be honest the site needs a complete overhaul, it has not been created with the visitor in mind at all.

Yeah, ouch, I have to agree. You need to re-work the site completely. You should search around the forum for tips and guides to use as a guideline when you rebuild it. Good luck!

Thanks for reviews guys.

I personally thought it was great - and so the people I showed it to (non-professionals though), but not anymore :p
It also has to do with the producer that fails for price and competition.
So, I'll just lower the ppc bids for that LP to a cent or two, and let it go where it goes.

I found some better converting supplements though, with just a couple of pages on the site (not even original content) I'm getting some new members into MLM.

...It's all about brands and brands awareness, hehe.
