1 - Monetize with Adsense
AdSense is the platform powered by Google that gives you the freedom to show appropriate ads to a domain on your blog. They will ask for things like the name, address, URL of your blog, making money online blog topic and many other things. Fill out the form carefully and submit it. People working at Google will review your form manually and approve if it is compliant.
2 - Advertising Banner Display
This is one of the best methods that all big companies use. In fact, the purchase of advertising space is very similar, in these principles and in its operation, to traditional advertising in the press or by display. It enables a brand to gain notoriety and to pass on elaborate advertising messages to potential customers. To buy space, you can contact an advertising agency. Most websites that display banners have an integrated control room or are attached to a control room.
3 - Make a Critique of a Product
Many of the reviews you read about various products are paid reviews. Companies pay bloggers to write positive reviews of the products. So, you can approach a few companies and ask them to write reviews about their products and promote with your blog.
4 - Sponsored Links
Many companies just want a link (an anchor) inside your article to do SEO of their website. So, you can write a relevant article on your blog and insert the link of this company anywhere in the article with an appropriate context. You can see a control room like Rocket links.
5 - Make a Video on a Product
If you have a popular blog, businesses will pay you a lot more if you can make a video review of their products. Video is a good way to broadcast information in a very short time.
6 - The Affiliation
With this method, you promote other people's product on your blog by displaying banner ads or writing reviews of the product. You could be confused as I already talked about these two methods above. So let's clear that confusion first.
In the 2 companies above, with the methods we pay you fixed fees for banner ads (say 100 € per month) and write reviews on your blog (say 100 € for a review. Affiliate marketing is completely different. Here you join the affiliate program for a company and they will pay 10-80% on every sale you make.You will get your unique affiliate link that will tell the company that this particular sale has been made by you.
