Google Adwords has long since served the internet marketing community by generating billions of dollars in commerce each year. While Google Adwords are certainly the most well known of the Pay Per Click services, there are other competitors emerging who may very well give Google a tremendous amount of competition.
Probably the most significant alternative to Google Adwords is Facebook Paid Ads. The name might not be creative, but Facebook is the most popular social network in the world. Millions of people use Facebook each and every day and PPC advertisements on the social media site can reach scores of potential customers.
The combined Yahoo/Bing Ads are visible on those two aforementioned search engines. Yahoo has always existed in the shadow of Google, but millions of people still use the search engine. They are also able to peruse the Yahoo Ads promoted through the search engines. Bing is Microsoft's search engine and it has had a long and troubled history under many different names and parent companies. Even though Bing might not be widely popular, there are those persons who do exclusively or mainly use it. As a result, creating PPC advertisements on the Bing search engine might be able to reach those who otherwise would never see them on Google.
There are quite a number of smaller PPC that vary in degree of their popularity. Services such as AdBrite, 7Search, and Clicksor would be among them. While they might not be as commonly used today, they could all become wildly popular in the future.
Newer alternatives to Google are likely to continue to emerge. For those interested in launching a comprehensive advertising campaign, this is surely a good thing. The more advertisements circulated, the more potential buyers can be reached.
