When someone is searching for a generic term, often they are looking for information, or in the research phase. Let’s take a look at the keyword phrase “jumper cables,” for example. If your site contains a page that sells jumper cables, this term may seem attractive because it receives a hefty amount of traffic. Here are some of the results I received when researching this phrase on Google’s AdWord Keyword Tool:

jumper cables – 27,100
battery jumper cables – 1,900
jumper cable – 12,100
heavy duty jumper cables – 1,000
buy jumper cables – 210

Now, if you ran a PPC campaign in for these exact phrases, I would almost guarantee that “buy jumper cables” would be your best converting keyword. When a user types this phrase into a search engine, we know exactly what they are looking for. If your page is properly optimized, you’ll have a shot at ranking well in the SERP’s.

Aside from the relevancy, generic terms are more often than not more expensive than long-tail keywords. Users searching for “jumper cables” could be looking for information on how to use them, or just browsing brands as they are in the research phase. It might be worth bidding on this term for branding purposes, if you can get it for a reasonable price, but don’t expect a high click-through-rate or conversion rate. As far as optimizing your page, make sure not to waste your time optimizing it around ambiguous keywords.
