I have this problem on Squidoo and EzineArticles, both of which where I publish, and I've never been able to resolve the issue on either sites, but perhaps because this site seems a bit more together, and is still smaller and younger (and from my experience, more responsive at addressing problems), it could be resolved here.
I'm having a bunch of erroneous keyword data show up in my statistics. For example, my page on chun mee green tea shows a visit from the keyword: "mahatma gandhi wallpaper"; none of these three words appear anywhere on the page's text, nor is this keyword in any way related to the page. I suspect that this keyword somehow got mis-assigned to my page, confused with traffic to the page Mahatma Gandhi Wallpapers.
Similarly, my page on Tea - Varieties, Brands, and Buying Tips shows traffic from "tard the grumpy cat", which I suspect actually landed through the page Popular and Fun Zazzle Custom Mugs: Tard the Grumpy Cat and More.
This sort of confused data makes it really hard to determine anything. It also shows up in Google Analytics. For example, Google analytics shows traffic to my page Respect in Religion with the keyword "ninjago books on wizzley", which seems to be directed to the page Ninjago Reading Books for Boys.
I also don't understand why I have this problem on self-publishing platforms but not on my own domains. I run numerous of my own domains and I just don't have this problem there.
