Now that's not too hard to do. They scan their magazine or newspaper clippings and attach them to online resumes as PDF files, but those clips only show that a writer has print experience. If you want to work in an online market, you need online clips as part of your portfolio. Here are your options:
- Start a blog or a website to create your online writing portfolio. Upload those PDF files to that site. Then, you can furnish the link to your potential employer -- either the link to the whole website or specific links to articles you want them to see.
- Write fresh articles on free websites and use those as your links (and put the ones you are particularly proud of on your blog or website). Take a look at HubPages. It's the site that I used and I monetized it to build residual income. I've heard promising news about similar sites, WriteEdge and InfoBarrel. Write a variety of topics and in a variety of styles. Your online publishings will start to build a name for yourself in the world of Google and other search engines (because when you apply for a freelance writing job, expect your name to be Googled).
Clients who hire freelance writers to work remotely like to see that their employees are comfortable in the Internet world. The more you post to your website, blog, or other writing site, the more comfortable you appear and the more confidence you gain.
