This is how I do my keyword research, because I want to know exactly what my customers are searching for, not just take an educated guess. This method will cost you money, not much if you can find cheap vouchers, but is a very good investment. And as they say - you've got to spend money to make money. It's done using an adwords account. You can use a voucher if you like, I don't bother, but it may be a good idea to save yourself a few $$$. (I'm not sure if the free $100 ones are running around anymore, but if not just grab one of the "spend $25 - free $75") Now I'm in tourism, but I can't see why this won't work for most people, but because I know tourism thats what my examples will be. OK, so my imaginary site is a tour and accommodation booking site about Hawaii. First you'll need to go into, or set up, your adwords account. Set up a campaign and an ad group. Inside that ad group you'll need to build an ad and set your keyword. Set your keyword as your main 1 word keyword, so for this example we'll use "Hawaii". It's very important that this is set as a "broad" match. Now for the ad - you don't want clicks, but you want a qood quality score. To get this use the main keyword "Hawaii" once on every line, you'll also need your landing page to have your keyword in it's url, title and a keyword density of about 2%. But remember , make it a shit ad - you want impressions and not clicks for this experiment. As for your ad positioning, it's controlled by your bid for that keyword. If you've achieved a quality score of 7 or above your 1st page bids will be cheaper. You want your ad's to appear down the sides in after position 3 - remember you don't want clicks to eat up all your research funds - you want the most impressions. To achieve this start lowering your bid until you get the "bid is below first page" notification. When you see this raise your bid by 1 or 2 cents. Now let your add run. Check back every so often to make sure your ad is appearing where you want it to, you may have to slightly adjust your bid up or down to do this. After all your $$$ are gone is when you can get your results. Using the details drop down select choose "search terms - all". It will display every search term that triggered your ad. Now as you only used a single word keyword there will be lots of shit there, but also some really good long tails THAT REAL PEOPLE ACTUALLY USE! This writeup is a pretty basic version of the way I do things, but if you follow it and run with it you'll be able to use 2 or 3 word keywords. For example "Hawaii Hotel", Hawaii Tour". I've used pretty much every keyword tool out there and , at least for me and my niche, this easily gives me the best results.
