This is an outlawed practice since Google instituted it a few years ago. Google seriously does not want websites to exchange links for the sake of developing its page ranking. In fact, Google has gone on a global war to reduce the page ranks of many websites to 0. Page Rank is determined by the quality of one-way links from quality websites to yours. So avoid exchanging links with anyone, if possible. You may exchange guest blogs with other partner blogs that link to one another`s articles, but do not do that too frequently. While you wait for your traffic ranking to rise, you could install Google AdSense into designated spots of your website. If you have quality blog content, it is desirable to embed Advertising as sidebars within your content. Otherwise, you may also integrate Advertising in site-wide spots, which appear all across your website. Google AdSense is not so profitable compared to other advertising revenues based on its Cost Per Click paradigm. You might want to look into text-based links advertising sources. After you have gained quite a standing in the eyes of Alexa (less than 1 million in ranking) or Google (page rank of 3 or more), consider TextLinkAds as a trustworthy source of advertising revenue. Depending upon the traffic ranking, your website may earn variable publishing rates and knowing of Joomla will help you to certain extend to present you organization/company on the market at a decent level.
