I want to know if any one have a free website, free domain, free web space or both and properly seo can get same traffic like other paid hosting.
Yes and SEO does not take into account the domain URL but quality of content and links to those content.
Yes why not! Search Engine Optimization does not bother about such facts about your hosting domain, web space and other stuffs. What it really count how much your site is beneficial to others. And how much effective is your site content.
Yes, because Google does not have interest in your paid domain or free domain. It have interest in your fresh content and quality backlinks.
yes sure if you do proper seo you will get definitely good traffic no matter your hosting is free or paid
