What are the most important factors involved in Landing Page Optimization?

Hello Umer, please have a look at the following points below: 1.
If you are running an advertising campaign, make sure your landing page describes exactly what your Ad says and displays exactly what they are expecting to see (Avoid increasing bounce rate) 2.
Your landing page must be user friendly, straight to the point with clear navigation 3.
If your success journey are users filling a form, make sure the textfields are clear and the submit button stands out.
Do not include a long form.
User interaction must be as short as possible.
4.
Do not include too much graphics as some heavy pages might not load properly on some browsers 5.
Test your pages on different browsers, operating systems and mobile devices.
6.
Make sure your landing pages are set up properly with Google Analytics or any measuring/monitoring service.
Make sure you test them as well.
Hope the above helps.
Good luck!

You mentioned that Visitors are not converting and Exiting from home page.
It means the keywords you are targeting are not related that's why visitors are exiting from the home Page.
They are not getting the right content they are searching for.
The another reason may be you are not engaging the visitors with a right content.
Try start putting offer or promotion on your website.

It should not have any distraction (clear llinks for navigation to other pages). It should clearly convey the message about your product/service/offer in its headline. It should have a clear call to action . Call to action should be of prominent colours according to the layout of the site. Normally in experiments we see orange color call to action always will have a great CTR compared to others.Its better to have your landing page as responsive for mobile and tablets as well unless you have targetted traffic dricing for any specific segment. Also in desktop and tablets on teh initial fold without scroll it should show all the important elements / images etc. Always call to action also better to be on the upper fold.
