In searching google ad words info on global searches, for a particular phrase, the search phrase is "music psychology", Google AdWords Keyword Tool lists 22,000 global searches and 8,100 local searches per month. Our page comes up #4 and averages 4.2 on a search for that term according to google webanalytics. However, the number of impressions is 900 with 170 clicks. If it is on the first page, it would seem that there would be 22,000 impressions, corresponding to the searches. Why the difference?? And how to calculate the actual number of impressions that will come up in a google search for a keyword? This would be under keyword search or keyword search volume.
You can track everything (clicks, ips, impessioons etc) with a tracking script/software like Prosper202 or bevomedia. It's critical to succeed in the cpa marketing.
There can be a whole bunch of reasons for this: 1) You're looking at broad match in the keyword tool. This number tells you that if you were bidding on "music psychology" in AdWords with a broad match setting, they could match you to up to 22,000 searches a month. These searches could be anything they deem as similar, like "music psych" or "audio psychology." So for organic that doesn't really tell you anything useful. On the sidebar you can check boxes for Exact and Phrase match types. It tells me that there are 4400 global and 1900 local monthly searches for all terms that include "music psychology" (that's phrase match). There are only 1600 global and 720 local searches for the exact term "music psychology." 2) If the search results are localized, you might not actually rank as #4 for most people. 3) You might see less searches if the search volume is volatile or seasonal. For example the keyword tool will list one number of monthly searches for "christmas trees", but you should not expect to get hardly any searches in July. According to Google insights, "music psychology" has its lowest search traffic in June, July, and August. It's not a huge enough drop to explain your numbers fully, but it's probably a contributing factor. "music psychology" doesn't seem like a particularly local keyword, so I think you are seeing a combination of #1 and #3.
