I know that this could possibly be listed somewhere on here. Ok, here we go. I am on adwords getting keywords very targeted pertaining to cars in Virgina. Adwords shows that some have a decent amount of traffic, and no comptetion, but no data trend. Are these keywords worth creating a campaign for. Maybe I am just thinking any help or criticism is welcomed.
No competition with decent traffic sounds more like an abberation in the Keyword Tool. Often, things look a certain way in the tool, but they don't pan out in real life. I would give it a whirl, since you probably won't be paying very much per click.
give any and every keyword variation a try. You never know what will work. Also, google traffic estimator is usually outdated and wont return the results for many traffic producing keywords. Google traffic estimator was designed to "ESTIMATE" traffic, not tell you exactly what to expect.
