Here's a link to the marketo docs for landing pages. If you follow the nav tree on the left you should be able to answer most of your questions.
Let me know if that doesn't answer any specific questions.
Thanks so much for your quick response and the link you've given is more useful. I'll go through the nav tree and may reach out to you if in case of any difficulties in understanding.
I may need more help from you on various topics
Have a good weekend mate!
