6. Not checking your browser and device compatibility
An effective landing page should be displayed correctly with all its features in any browser on any device.
Browser compatibility is how a landing page looks in various browsers. Different browsers read, understand and interpret the website code such as HTML and CSS, individually. Safari, Chrome, Firefox or Microsoft Edge don’t render landing pages in the same way. Also pay attention to in-App Facebook Browser, because it may sometimes turn out to be a troublemaker. After clicking on a link in a Facebook post, a page is opened inside the Facebook window and might not be displayed as intended. It may cause a loss of visitors' attention. That is why it is crucial to provide browsers’ compatibility on your landing page.
Nowadays, visitors are accessing landing pages from their mobile devices much more often than from PCs. It means that compatibility not only with browsers but also with mobile devices is a matter of life or death to your landing page. Use Responsive Web Design approach to provide a perfectly-looking and working landing page on every device. Ensure compatibility for Apple users, Android users, etc. Making your landing page compatible with as many browsers and devices as possible increases your landing page reach and results in a growth of leads.
