Keep in mind that some topics attract much higher payouts per click than others. For example, if your site is about topics such as debt consolidation, web hosting, Viagra, online casinos, valium or asbestos-related cancer, you’ll earn much more per click than if it’s about thingamajigs.
In fact, “thingamajigs” would be a very bad choice. Although there are thousands of pages mentioning them, no one is spending money on Google AdWords to advertise them. On the other hand, if you concentrate only on top-paying keywords, you’ll face an awful lot of tough competition. So do some careful keyword researches before you build your webpage.
Above all, make sure the page you create offers great value to people interested in the topic. When you provide excellent information on a specific topic, your visitors will benefit and will be more likely to click
through to relevant AdWords.
