I have an ecommerce store and I'm wondering why the name of my website is the most commonly searched keyword according to analytics. I rank for a number of keywords for deep product pages and that is reflected in Google Analytics under keywords but I can't imagine why people would be typing in my website name as it is not a well known store (yet). Where do these results come from?
It depends what your website domain is at the end of the day. If it is a keyword based domain then the likelihood is, yes you will get natural traffic and higher ranking for those keywords.
I get a lot of results that just say "not provided" for the keyword results. Where do these come from?
Not provided is when a google user is signed into their google account. They are searching via SSL so the keywords are not transmitted and picked up by your analytics JS. Quite annoying...
