Be social. Whatever your business, whatever your venue, keeping your name in the air is key to internet success. Have a business account on Facebook, Twitter, and LinkedIn. If your business is graphically oriented, have accounts on Flickr and Tumblr as well. Whenever there is news of any kind—a new contract, a new page, a new entry, a new photo—cross-post it to all your social media sites. Also make sure those sites link back to your main website, and that your website has links to all of them.
You know this one already. You include links to products you are promoting as an affiliate and every time somebody buys the product, you get a commission. With a blog, you can integrate advertising with content to make it even more likely you’ll get the sale. For example, you could do a product review—which is useful content—and then include a link to buy the product under an affiliate link.
Take it seriously. Yes, you’re applying for an online job. Yes, you can do the work in your underwear, but that doesn’t mean it’s not a “real job”. You must treat it as such or they aren’t going to treat you as a serious candidate. You aren’t the only one who wants to work in their underwear. In fact, the competition online is likely higher than it is in your local area.
