I want popular my site. I want include in my site some importment and valuable things. I have some idea online free sell buy. Give me some idea people's need and come to my site again and again.

Make it useful and update it regularly.

You must provide quality and interesting content first so that it's worth visiting and useful to your customers.

May I ask if what kind of buy and sell does your site have?

1. Quality content

2. Quality design

3. Quality marketing

Design is not as important as marketing and content. If you have a fixed budget or no budget i would focus on content and marketing because having a site will do nothing unless people come to it. Content is King on the internet that is what it was designed for and what it is used for. It wasn't Designed to look pretty. although making it look pretty can make your site look more professional and trustworthy. BUt you need to decide what is most important to you and which will help you accomplish your goals.

 

I hope this gives you a base to start your own web site.
