How to Earn Passive Income Through Affiliate Marketing and Google Ads

  • Lisa Andrea launched a financial blog in 2021 and booked $8,000 in revenue last month.
  • Through her business, she shares tips on generating multiple streams of income.
  • Andrea outlines 9 of the easiest ways to earn passive income, including eBay and stocks.

Lisa Andrea discovered the possibilities of passive income as a child, when she started a lemonade stand. She hired her younger brother — paying him a percentage of the profits — and reaped the remaining revenue without working at all.

Then a few years later, she began selling old clothes on eBay. By the time she was 15 years old, Andrea was making hundreds of dollars a month from that venture. Today, as a 34-year-old entrepreneur those have turned into thousands of dollars and inspiration for her business.

From her experience building passive income streams and teaching herself the fundamentals of financial literacy, she launched the financial-advice blog The Financial Cookbook in February 2021. Through her company, Andrea teaches other women how to scale their financial freedom and find freedom.

Her business, which she runs as a side hustle, booked $8,000 in revenue in May alone, which Insider verified with documentation. What’s more, she makes additional income through investing in stocks and selling on eBay.

Andrea spoke with Insider about nine methods of passive income she encourages everyone to try.

1. Start a side hustle

Andrea continues to work full time as a marketing expert for a Big Four accounting firm for the income, network of colleagues and friends, and additional events and opportunities. However, she does advise people to start side hustles in industries they are knowledgeable about if they’re looking for extra cash.

For her, that came in the form of financial coaching, but certain industries are more promising for entrepreneurs right now. However, those looking for an additional job should be wary of the additional workload.

2. Google Ads

If you have a website with regular viewership and traffic, Andrea suggests charging advertising fees.

For example, Google’s advertising program AdSense allows online-content creators to monetize their websites or YouTube videos and generate income through ads.

“AdSense works by matching ads to your site based on your content and visitors,” and content creators should enable advertising space and ensure it’s available on their websites and sign up for the AdSense program to start earning, according to Google.

3. Affiliate marketing

Affiliate marketing allows content creators to direct viewers to another brand’s site. Then, when a viewer makes a purchase, part of the profits go toward the creator.

“All you have to do is apply for affiliate programs, explain why you want to work with them, and how you’ll drive income,” said Andrea.

Some popular affiliate programs include Amazon, LTK (previously known as rewardStyle), and Partnerize.

4. Sponsored posts

Andrea said companies typically contact her about brand partnerships, but she encourages other entrepreneurs to be more proactive when looking for passive income avenues. Sponsored posts can be a lucrative way to generate income as a content creator.

When reaching out to brands about potential partnerships, make sure your media kit is comprehensive and enticing — it’s how companies gauge whether they want to work with you.

5. Sell products, templates, and courses

Andrea also sells her own products, including a résumé template and a virtual “75 hard” challenge, which allows users to track their habits for 75 days.

Depending on what you’re knowledgeable and passionate about, creating and selling virtual or live courses is another way to generate extra cash, she said.

For example, Jessica Hawks is a virtual assistant and career coach. Her online courses, which she launched in 2020, helped scale her business to $1 million in company sales.

6. Invest in bonds

Bonds are loans corporations or institutions take out and give to investors. They are low-risk market investments in comparison to stocks, making them a great option for beginners, she said.

When purchasing a bond, investors have to wait until the value “matures” to see the return. But if you are willing to wait long enough, some bonds have interest rates as high as 9%, Andrea said.

7. Invest in stocks and crypto

The stock market can be really complicated, which is why Andrea breaks it down into two categories throughout her blog posts: stocks with dividends, and cryptocurrency.

When deciding where and how to invest, you should look at your budget, timeline, and risk tolerance, she said. For example, some crypto stocks have plummeted in recent weeks.

8. Real estate

Purchasing, renting, or selling properties is a common route to passive income. But even those without large sums of expendable cash can take part through fundraising strategies like crowdfunding, she said.

Some companies, such as Fundrise and DiversyFund, allow people to invest as little as $100 into real-estate properties and generate a percentage of their investment when the property earns money, Andrea said.

“If you’re investing $100, you’re not going to make a huge return, but you’re still going to make the same percentage as the person that invested $100,000,” she said.

9. Sell on e-commerce sites like eBay

eBay is the most cost-effective platform for e-commerce sales, Andrea said. She recommends selling old clothes, coupons received in the mail, or finds from garage sales or local stores.

Nicholas Waskosky, a Poshmark seller, earns five figures a year selling old or upcycled clothes on the platform.
