We've got an active adwords account and I'm also using the Google keyword tool to generate keyword lists as in my opinion it's the easiest/quickest to use. When I run a keyword query, I sort by Avg. Search Volume* and export the data (.csv). If I run several queries for unrelated keywords, I'm left with multiple lists of keywords.
*Avg. Search Volume: The average global monthly traffic volume that each keyword has received over the past twelve months (Google)
1. Is the Avg. Search Volume a reliable indicator to say that from top to bottom (when keyword list is sorted by Avg. Search Volume in descending order), the keywords that were searched on the most over the last year are the ones with the highest Avg. Search Volume?
2. I need to know if the Avg. Search Volume is camparable against different keyword queries. If I have two lists generated from different keywords, one looking at hotel related keywords, the other pub related keywords, is the data comparable when looking at Avg. Search Volume? For example, 'hotel london' has a Avg. Search Volume of 0.6, whilst 'london bar' has a search score of 0.53. Does this tell me that over the last 12 months, 'hotel london' had a higher search volume than 'london bar'.
I'd really appreciate your help. I checked several help topics at Google and haven't had a response to my contact us post, by definition on Googles site, the answer to the first question is yes, but I need to ask both questions.
If this is correct, this is a great way to generate keywords lists and identify keyword opportunities if you're a big enough site to compete on those words.
BIG thank you for your help.
