Marketing experts recommend websites remove the navigation menu and limit internal and external links on the page.[7] The form length mirrors the value of the offer[clarification needed]. They may also include a relevant image, animation or short video. These pages also tend to contain small icons (i.e. of Facebook, or Twitter) to facilitate social media sharing.

Significant improvements can be seen through testing different copy text, form layouts, landing page images and background colours. However, not all elements produce the same improvements in conversions, and by looking at the results from different tests, it is possible to identify the elements that consistently tend to produce the greatest increase in conversions.[citation needed] 

If a sales opportunity does not move down the funnel, the sale will not happen and the opportunity should be removed, hence the “leaky” funnel. A leaky funnel is not necessarily bad; as a salesperson, you want to focus on opportunities that are likely to yield results. It is the nature of sales to have to remove an opportunity from your funnel. It does not mean that you will not sell to that account (a positive action by the customer can put them back into the funnel), but for the time being, you should centre your attention on opportunities that remain in the funnel.
Trulia did something very similar to with their landing page. It starts with a simple form asking for "an address" (which sounds less creepy than "your address," although that's what they mean). Below this simple form field is a bright orange button that contrasts well with the hero image behind the form, and emphasizes that the estimate will be personalized to your home.

Of course, the address itself won't be enough to estimate the value of a home. It just denotes the home's neighborhood. That's why the next page follows with more questions about the property itself, like number of beds and baths. Below, you see the copy "Tell us where to send the report" -- with a disclaimer that, by entering this information, you're agreeing to connect with a real estate agent. This is a great example of a company giving value to their visitors from the get-go, while setting visitors' expectations about what will happen as a result.

Hi Terence, first off I would like to say that an interesting and thorough review. The fact that you go into so much detail about Funnel hacks, both the pro’s and the con’s really makes me believe in it and you. It sounds like something I will definitely consider as soon as I get my own product to sell (which I am still working on at the minute). And if it works then it’s worth every penny I say.
Full disclosure: IMPACT is a HubSpot partner -- but that's not why they're included here. IMPACT's landing pages have long been a source of design inspiration. I love the simple layout of the page, from the large headline copy and detailed featured image, to the outline that surrounds the form, to the colors and fonts that are very pleasing to the eye.
Open-ended experimentation. This approach is similar to closed-ended experimentation except that more variations will be added for testing and experimentation will not stop when a winner is found. This method is used by large corporation to dynamically improve their conversion rates and improve user experience. Landing page can also be adjusted dynamically as the experiment results change to further enhance user experience.
