Tool ( https://adwords.google.com/select/KeywordToolExternal ) is showing around 1/3 last month searches count and 1/3 average last year search count when I use it without Login my adwords account than when I use it after login. i.e for example-- Search Engine Optimization ----- Approx Avg Search Volume is 135,000 --- (without login) Approx Avg Search Volume is 550,000 --- (with login) Anyone experience this? Why it is like that? Which one to trust? Thanks in advance.
I get the same. Doesn't seem to be any info about exactly how each of these numbers is derived, but what I can see is that the non-logged-in estimated traffic volume is much closer to the number of impressions I get for some Adwords keywords that are limited to organic search only (i.e. excluded from the content network).
For me: language english + all countries Search Engine Optimization Searches in July: 1.000.000 Searches: 823.000
Funny you should bring this up. I just read a Case Study where this guy shows you exactly how he set up his site, product, keyword research etc. The one thing he mentioned was to use the research tool when you log into your Adwords account. He didn't say why but you will see a big difference the majority of the time. Good luck, Zeek
