One of the ways in which you can earn money from your Joomla website is by running ads on it. If you are in business yourself, you can use your Joomla website to promote the business. So this would be an arrangement where you would be running your own ads/promotional content on your Joomla website. The other alternative is to run other people’s ads on the Joomla website. Then those other people, whose ads you run on your Joomla website, would pay you for the favor of allowing their ads to run on your site.
Of course, if your Joomla website is to be worth running ads on, it needs to have traffic. And for you to get traffic into the website, you have to create worthwhile content. The content in question here could really be anything (provided it is something people are interested in). You could even have various website reviews and user guidelines on the Joomla website. If, for instance, there are lots of Darden restaurants around, you could decide to provide krowd login guidelines in your Joomla website. These would be instructions aimed at helping the folks who work at Darden to navigate the krowd employee login process: knowing that that is something they are likely to struggle with. So the most important thing is to understand the information people are likely to be looking for, and then ensure that that is the information you build your Joomla website around.
You can include your contacts on the Joomla website, with a request for people who are interested in advertising on it to contact you. Alternatively, you can opt to enroll the Joomla website in a web-based advertising program. So this would be an arrangement where you would be earning revenue whenever people visit the Joomla website and click on the ads that would be running there.
