"An investigation of the keywords people are finding your site by, even the limited GWMT version should tell you a lot about the type of traffic you're getting."
Well, my site has two areas (ecommerce and article / blog section) on the same domain.
On the ecommerce side of my site, I sell Blue Widgets.
In my /blog/ directory I have lots of articles about Blue Widgets.
Looking at the GWT query data, it is overwhelmingly related to "meanings". something like:
Blue widget Meaning
Blue Widgets Meaning
Blue Widget Symbolism
Blue Widget Shapes
Types of Blue Widgets
Blue Widget Settings
Different types of widgets and their meanings
I don't get any traffic for something like "Buy Blue widgets" or even just "blue widgets"
I wonder if my information / articles have "poisoned" the ecommerce section of my site.
On my articles (which get 4-times as much traffic as my ecommece pages), I have image links to the products I sell. They rarely get clicked on though.
For example: My most popular page is "blue Widgets Meanings" and it has image links to my main Blue Widgets ecommerce page (same domain).
Over the last week, it had 2,990 page views.
The image links to the ecommece pages on my site had only 24 clicks, which is a .8% click-though rate (24 clicks divided by 2,990 page views).
Meanwhile, the bulk of my traffic growth has been to my article pages (which I can't seem to monetize) and my ecommerce traffic has been declining constantly.
