Conclusion If you get keyword's & phrases from one keyword generator you could miss out on some Golden keyword's that are in use but you'll never find. A random selection (see footnote) of a keyword phrase presented in these findings showed less than half (43.3%) of the possible keyword phrase variations found by using only one keyword generator. Wordtracker gets its data from a relatively small percentage of total search engine users (1.8%) as do Ad Words Analyzer and Niche Finder (est 4.9%). It's clear that more than twice as many keyword's resulted from using more than one keyword generator. It's not until you do a lot of keyword research using different tools you realize that one keyword generator is not enough. If I'd selected a different example keyword phrase, would the results be different ? Yes of course, the percentages would be different. But you'd find far fewer keyword phrases with only one keyword suggestion tool. During some recent keyword discovery on over 2,000 different keyword phrases, on a final selection of 645, I discovered 194 of them did not exist at all in one of these tools, that's 30% or almost a third. So, is one keyword generator enough ?The answer to that question must clearly be NO !

Google Footnote: The choice of the keyword phrase was not entirely random in the sense that I wanted one that would be a popular search term. But it was not chosen so as to produce this type of result. Similar results were produced on much larger numbers of keyword's.
