Of the many keyword terms I target on one particular site, a certain 2 word phrase is a very common occurrence. One of the 2 words in the phrase is "website".
In Webmaster Tools that word does not appear in the keywords list at all. The top word in the keyword list is the other word that "website" is almost always bundled with on the site.
For example, let's say the phrase is website layout. The word "layout" is listed as the number one keyword in WMT. The word "website" is not listed anywhere in the report. The 2 words rarely appear on site without each other together.
Not sure how long it's been like that in WMT. The site used to be listed in the top 5 serps 6 - 8 months ago. Now it's not even in the top 50, which got me looking and wondering. Does Google ignore "website" now because it's ubiquitous?
Anybody who also targets the word website in any way, please see if it is listed in your WMT report.
