How to Make Money on Web for Free

1. Become an online web content writer. Look for writing job postings at sites such as Craigslist.org or FreelanceWritingGigs.com, or contact websites directly for available writing positions.
2. Offer to work for companies as a virtual assistant. Virtual assistants perform a wide variety of administrative, writing and website duties using the Internet from home. Both Elance.com and ODesk.com allow users to list their skills and connect with potential employers.

3. Sell your used or other unused clothes and household items through online auction sites such as eBay. There's no startup fee associated with using eBay; you pay only a small fee if the item sells.
4. Open a Google AdSense account and add it to your current blog or website. Joining AdSense is free, and when someone clicks an ad on your website, you earn money from that click.
