A blog highlights your technical ability and showcases your ability to write blog posts. Your blog can be about different topics than those you write about for your clients. In fact, it should be on a topic that interests you. Visitors will see that you can not only write, but you can also build an online community. A good blog has the potential to earn you many referrals for more clients.
Designing web logos obviously isn't for everyone. It will help you quite a bit if you've got some background in graphic design or if you're relatively proficient in design tools like Adobe Photoshop, Adobe Indesign, and Adobe Illustrator or other like products. You don't necessarily have to have a degree in graphic arts, as long as you're able to put together eye-pleasing designs that others will love and pay for. Use Fiverr to find people in need of logos!
Great list! I’ve used Poshmark to sell clothes/accessories. You take up to 4 photos, add a description, and set a size, color, and brand. I’ve sold 3 items so far (two dresses and a pair of shoes) and it’s easy. The buyer can purchase at listing price or make you an offer, to which you can counter-offer. At all times, you can see what your profit will be from your listed price. Once the transaction is accepted, you are emailed a prepaid shipping label to print. You package your item up in a brown box and ship, and when the seller receives it your funds are released. You can cash out as a direct deposit to a bank account at any time or use the funds to shop. I’ve also purchased a pair of jeans on the site and they arrived as expected. For like-new and designer labels it’s a great way to clear your closet and make a little cash all at once.
As for other tips, all I can say is “a penny saved is a penny earned”. If you are running out of ideas to make money, start saving. Some quick “low hanging fruit” tips to save some quick cash include – switch to MetroPCS or Boost for cellphone (I only pay $20/month), switch auto insurance to Insurance Panda ($25/month), and start using GasBuddy (saves me like $100/month at least. I drive a lot).
One of the cool things about Google AdSense is that it's so easy to get set up. If you have a blog or website, you can sign up for a free Google AdSense Account. From there, Google will give you a unique code that you will paste onto your website. Google takes it from there, tracking your page views, traffic, and earnings on your behalf. There is no upkeep or maintenance to get this thing going, which makes it a no-brainer if you have a website already.
