Need more ideas on how to make money online? Another strategy is using webinars to market your product, service, or course. I’ve done webinars to promote my financial planning practice and to drum up interest in my online course for financial advisors. With a webinar, you’re basically offering a lot of tips and advice for free — usually in a live format. At the end though, you pitch your paid product or service with the goal of securing a few deals.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
For my Adsense plugin which you can get here https://wordpress.org/plugins/adsense-made-easy-best-simple-ad-inserter/ I’ve created a PRO version (https://www.seo101.net/adsense-made-easy-pro/) that is available to those that sign up for my mailing list. It’s not much but it gets me 5 to 6 subscibers a day. And best of all I know exactly what my subscribers are interested in… WordPress and Adsense:)
Or, you could make up a fun game where the first person posts a picture illustrating their pet’s name. The next person has to guess their pet’s name based on the picture. So, if I had a dog named Spot, I might post a picture of a spot. (I did say to keep it simple!) Of course, it’s easy to guess, but it’s also fun and all you have left to do is sit back and watch the comments roll in.
Offer to watch children or pets. If you know anyone who has children or pets, you could easily begin a side gig as a babysitter or pet sitter. To let people know you’re interested, send out a group email describing your services, post an ad on Facebook, or tell friends and acquaintances about your availability in person or over the phone. You can also create a profile on a babysitting referral site like Care.com.
People love to learn, and webinars are an excellent way to impart your wisdom to your eagerly waiting audience. Combined with an effective social promotion campaign, webinars are a great way to increase traffic to your website. Send out an email a week or so ahead of time, as well as a “last chance to register” reminder the day before the webinar. Make sure to archive the presentation for later viewing, and promote your webinars widely through social media. If you're wondering how to do a webinar, click the link for some tips.
Creating a jobs board website can be another profitable venture. The ‘jobs’ field can be quite saturated, so it is important to find a niche that is still crying out for a jobs board website. Monetize this type of site by charging businesses to list their jobs on your site. Those searching for jobs could also be charged a fee to access the higher paying job adverts.
Multi-vendor marketplaces, like ThemeForest, can be very successful. Chose a niche and create a vendor website for it. Your marketplace could be anything, from a platform for local artists to sell their work on, to an online digital product store. Once set up, invite people in that industry to sell their products on your site. You take a percentage of their profits when items sell.
