Solo ads are a form of email advertising where you rent space in someone else's email list to promote your product or service. 

Essentially, the owner of the email list sends out your promotional message to their subscribers on your behalf, making it a direct and targeted way to reach potential customers.

For niches like "make money online", "crypto" and "SaaS," solo ads can be particularly effective.

By using solo ads to build your email list, you can tap into established audiences that are already interested in similar topics, thereby increasing your odds of making money right off the gate.

This method basically allows you to build your email list on autopilot. It's 'done for you' traffic, for a low cost.

How To Identify Reputable Solo Ad Vendors: Look for vendors with good reputations in your specific niche. They should have a track record of delivering high-quality traffic that converts via testimonials. There are various online platforms and forums where you can find reviews and testimonials about different vendors, but my place of choice to buy Solo Ads is Udimi.

What To Do After Purchasing Clicks From A Solo Ad Vendor: You simply need to create a tracking link (with your lead capturing page in it). To track clicks, you can use a tool like Qliker. With that said, if you don't want to use a click tracker tool, you can simply send them your lead capturing page link directly to get the ball rolling. Either way, the Solo Ads provider will give you stats once their clicks are completed.

How To Determine If The Solo purchased Was Efficient: Nowadays, if you get 25-40 subscribers on your email list, per 100 clicks you purchase, it's the average. Anything below that is considered a bad solo, or that your lead capturing page needs a little bit of work. Either way, a good opt-in rate is between: 25%-40%. So when you are testing Solo Ads sellers, this is what you should be aiming for.
