It's no surprise Unbounce is near the top of this list -- they've actually written the book on creating high-converting landing pages. Although there are lots of amazing things about this landing page, the two that I absolutely love are: 1) The use of a chat window instead of a classic form, and 2) the detailed -- but well packaged -- information below the form.
Landing page optimization (LPO) is one part of a broader Internet marketing process called conversion optimization, or conversion rate optimization (CRO), with the goal of improving the percentage of visitors to the website that become sales leads and customers. A landing page is a webpage that is displayed when a potential customer clicks an advertisement or a search engine result link. This webpage typically displays content that is a relevant extension of the advertisement or link. LPO aims to provide page content and appearance that makes the webpage more appealing to target audiences.

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]
FACT: This amendment ensures essential health benefits are the federal law of the land and maintains other important protections. States have the option to obtain a waiver regarding federal essential health benefits, but the state must publicly attest its purpose for doing so (to reduce the cost of health care coverage, increase the number of people with health care coverage, etc.) and it must specify the benefits it will require instead of the federal standard. NO STATE, under ANY circumstances, may ever obtain a waiver for pre-existing condition protection, prohibition on gender discrimination, for guaranteed issue and renewability, or for the right of dependents to stay on a family plan up to age 26.
