Concepts that may seem completely off the wall or worth absolutely nothing may turn out to be gold mines. If research indicates that the subject is a dead end, then at least you have eliminated one possibility and saved yourself the trouble of pursuing that option at a future date. On the other hand, you may be surprised with what you find.
Using these lists of words or subjects that you have compiled, take to the Internet and start doing some digging around. The first thing you want to ascertain is how much interest there is associated with that particular word or phrase. One of the easiest ways to get a handle on this sort of thing is to use word tracking search engines online. There are several well-known ones that are very easy to use.
All you basically do is type in your word or phrase and let the program search the entire web for results. What will happen is that the system will return a list that contains not only incidences of the word or phrase that you entered, but also expanded phrases that include that same word or phrase. You also get an idea of how many sites around the Internet contain text with that word.
This can be a great way to qualify the subjects and see if there is a large amount of interest in a given subject and related topics or information. A lot of hits means that you may want to look further into that subject as a possible foundation for a marketing campaign that is related to that word or phrase.
For example, if one of the subjects that came up on your lists happened to be "dog," and you find that the word returns close to a million hits on its own, and then you may have found a broad subject to explore. Looking down the list, you may find that "dog house" and "dog training" returned a sizable number of hits, as did "dog treats." With just a little digging, you have uncovered three potential services or products to market.
Moving one step further, you can explore each of these marketing subjects a little deeper by clicking on the word or phrase and canvassing the actual returns. Here, you may begin to see a pattern among the hits that bubble to the surface of the search engines.
This can help you to further refine your idea of what to market. For example, if you notice there are a lot of these that have to do with making a particular product at home, you may begin to think in terms of marketing home assembly kits related to that subject. Perhaps the home assembly requires the use of certain tools.
