Cost per click advertising (e.g. AdWords, Yahoo! Search Marketing) overcomes this problem by charging advertisers only when the consumer clicks on the advertisement. However, due to increased competition, search keywords have become very expensive. A 2007 Doubleclick Performics Search trends report shows that there were nearly six times as many keywords with a cost per click (CPC) of more than $1 in January 2007 than the prior year. The cost per keyword increased by 33% and the cost per click rose by as much as 55%.
So if you are interested in Australian business opportunity leads, just sort them by country and contact members interested in your opportunity (see screen shot below).  To avoid random spam invites, the platform uses a smart point system to regulate engagement. l will discus, how you can earn free points and how you can use them to reach out to prospects.
My point in doing this video and blog post is to say that anything that you do where you are reaching out to people and exposing your products and/or business will work.  And...the most important point I really wanted to make is this.  Down time is bad time.  If you have the time, you should be doing something that is revenue producing and productive.
Set up marketing automation workflows to categorize leads and segment them into lists using criteria established in Step #1. Use these lists to nurture leads with relevant content and personalized email communications. Also use them for targeted campaigns, segmenting leads with a certain role or title or within a certain industry or market segment.
The outbound method involves a proactive attempt to reach out to your audience. This usually begins with purchasing lead lists. You then contact these leads by calling them directly (cold calling) or sending them physical mails (direct mail). For a wider reach, businesses look beyond lead lists and use billboards, print ads, television ads, and radio ads. The emphasis here is on budget, media connections, and how much marketing muscle you can flex.
With the growth of the internet, the world has changed from one of information scarcity to one of information abundance.  In fact, according to Google chairman Eric Schmidt “there was 5 Exabytes of information created between the dawn of civilization and 2003, but that much information is now created every two days and the pace is rapidly increasing”.  
Cost per acquisition advertising (e.g. TalkLocal, Thumbtack) addresses the risk of CPM and CPC advertising by charging only by the lead. Like CPC, the price per lead can be bid up by demand. Also, like CPC, there are ways in which providers can commit fraud by manufacturing leads or blending one source of lead with another (example: search-driven leads with co-registration leads) to generate higher profits. For such marketers looking to pay only for specific actions/acquisition, there are two options: CPL advertising (or online lead generation) and CPA advertising (also referred to as affiliate marketing). In CPL campaigns, advertisers pay for an interested lead — i.e. the contact information of a person interested in the advertiser's product or service. CPL campaigns are suitable for brand marketers and direct response marketers looking to engage consumers at multiple touchpoints — by building a newsletter list, community site, reward program or member acquisition program. In CPA campaigns, the advertiser typically pays for a completed sale involving a credit card transaction.
