Hi there, Sorry I've been a bit quiet of late, we're going through a huge rebranding exercise as well as staying on top of client work. Anyway. I've got an issue with keyword research phase of a client remarketing. Trying to decide which keywords to target (aren't we all?) The client has 3 months of back data in Google Webmaster Tools, which helps us to see Impressions, CTR and actual click-throughs etc. Now, they rank #1 on Google.com for a certain keyword (logged out, of course). According to Google Keyword tool (Logged in) there are 2.7million searches per month for this keyword. With the average CTR being 18% for a #1 keyword that should be bringing in 400k visits. However, take the same keyword in Google Webmaster Tools and the impressions are actually around 1,600 per month with a CTR of 9%. Different CTR's for different sectors I can accept. What I don't get is the vast difference between the impressions in GWT compared to the alleged search volume coming from the Keyword tool. Really need to understand this so we can better select keywords and judge approximate traffic expected if ranking #1 for a keyword. Any help would be really useful. Thank you!
