-Ray Edwards

The most important thing is a clearly seen "Call to Action" button! Another aspect is a clear even a minimalistic page. The days are gone when a lot of marketers was trying to put all the info they have into landing page, just to 'prove' to costumer that their product is the best. Don't use large texts, just a few strong and concentrated sentences about why your product is worth buying. short video could also work moreover, just wanted to say that if your product isn't worth a penny, than even a good landing page didn't help to sell it.

101 tips holy molly!! lol

Your landing page should be different from everyone else's
It should have a very strong call to action
It should "promise" one very simple thing and that one thing should be it's center focus (usually giving away something for free)
That one thing should be enticing as all heck to your target demographic and it should deliver on it's promise!
Then it's really just a matter of playing around with the words and images and color scheme from that point to optimize.

It's more an art than a science but there's a bit of science mixed in there... somewhere.
You can always just do a Google Image search for "squeeze pages" or "landing pages" to get some ideas to model your's after if you need inspiration.

or

use one of the many readily available squeeze page creation plugins / softwares floating around the webspace, they seem to work pretty decently, though they do tend to create some cookie-cutter results but hey, those templates are usually shown to work for the most part.

Stills your breath so ya gasp on in like ya never knew.

good job !!!!

It should look good. The first impression is based on the overall look. So grab a good looking professional template. And also it should be targeted to a specific audience and talk their language. Of course it should promise to solve a specific problem too.

I would say the most important should be FOCUS. There should be only 1 thing for users to do on your landing page once they get there...which is the Action you want them to take.

Nothing should distract from that, meaning anything that does not help the user to take action as fast as possible should not be on the page.

So safe to say, keep it as simple as possible. Making sure the call to action is the main thing that catches the viewers eye?

Benefit driven headline. Strong call to action and for your optin form. Use email only NO name. The more things people have to do, decreases conversions.

"Landing page" is generic and could be many different things.

A good lead capture or "squeeze" page should offer a visitor only two options - Opt-in or leave.

Captivate - Use creative images, video and clear headlines to capture and KEEP visitors on the page.
Motivate - Use testimonials, convincing copy to motivate your visitor to take action. Create a sense of urgency to encourage the visitor to "do it now" vs later.
Dare to be different - There are sooooo many landing page builders and templates that look the same. Don't become a victim of watered down designs, find a way to stand out and be different.

Good rules are:

- Good headline
- Attractive sign up form
- Straight to the point
- A simple background color (not an image)
- Good call to action and benefits of what they'll learn
- Always capture their name also

I focus on this thing

1. Promote a positive first impression
2. Take advantage of trust elements
3. Increase the conversion rate

Make sure that the landing page is first very simple. Avoid stuffing the landing page with lots of content. People hate looking at landing pages that are cluttered with content making it absolutely difficult for one to identify the content they need on the page. Make sure also that the colors you are using are relevant to your entire branding of the organization or company. People visit the landing page just to get a glimpse of what you are offering. Avoid using lots of colors since they will cause unnecessary destruction. Colors can be a plus to your landing page and at the same time be a minus to your side.

Powerful headline + list of benefits bullets

Just mind control them. The amount of free will people have is roughly 1,000 times smaller then the amount of free will they think they have. If you don't understand the concept or don't know how this works, sorry. I won't tell you.

1. A landing page should have a single purpose and thus a single focused message.
2. Ensure the primary headline of your landing page matches the ad visitors clicked to get there.
3. Show your product/service being used in context.
4. Use real testimonials for authenticity.
5. Make your call to action (CTA) big and position it above the fold.
