Hello, Usually, I use this kind of landing page : http://www.meetic.fr/ --> A Form, a picture/logo and no links. A buy button on the second page. Do you think this kind of landing page could convert better ? http://www.chutedescheveux.net --> A long description, ...,..., a buy button on the bottom.
The more expensive the product, the longer the landing page. For a free dating site, it should be short. A long landing page would make it seem more like a scam, like why do they need such a long page for such a simple product? If your product costs a lot, you have to explain why it is worth it.
I think sometimes they can be a little too long and from personal experience that can be a little off putting.
So I have created a 'long page' but not too long so it doesn't look like a scam. I am running a A/B testing and should get the results monday.
Which conversion rate do you get from this page ? 10% sign up ? 35% sign up ? http://www.horselayingprofits.com/ The maximum I get from a page designed like this (http://www.meetic.fr/) was 25% with a very target traffic (and for a free sign up).
I personally hate them long landing pages and prefer to shorter ones. Just try and add as much relevant information about the product as you can, but make it straight to the point. Most of them longer landing pages, I just avoid.
I always use a separate landing page for say clickbank affiliates it might be a tad longer than the one above but not by much.
