I was going to buy Keyword Bible Pro, which is referred to as a “Complete, Customizable and Searchable Holy Grail of Keyword Research” but as it costs $350, I asked around first. Here is what a reliable source had to say about Keyword Bible Pro:

I’m pissed off. Why?

Well, I spent $500 for the Keyword Bible Pro and upgrades. I just got around to filtering the latest update yesterday.

I was so surprised by the results that I filtered it TWICE. Well, I filtered it once removing odd punctuation and what not as well as against the bad words list that Glenn had and what I found was very interesting… look at this:

First, I combined all the files into one huge file. It was 500MB in size with 19.5 million lines - yay - that’s a ton of keywords you think!

So off I go filtering…when it’s filtered with punctuation and bad words removed it’s 52MB in size and only 2.2 million keywords?

Must be some “bad” bad words in there…so I filter it again without using the bad words list. This time I get a file that’s 60MB in size with 2.5 million keywords.

The end result of all of this is that this “upgrade” (ed: Keyword Bible Pro) has a grand total of around 2.5 million usable keywords in it. What a ripoff!

I wonder what Scott has to say about this …
