Google has banned the default reference keyword used by GTrends SE from Google Trends. Damn.
Therefore, I just uploaded a new version, which uses a different keyword.
Note that if you already have GTrends SE installed, downloading the new version will not automatically change your ref. keyword (this is by design). You need to change it manually by clicking “Settings” and entering a keyword and searches/day in the “Reference keyword” panel. I recommend you find your own baseline keyphrase, but, if you really don’t have a keyword to use, ask me (I won’t put the keyphrase in public here so that it doesn’t get abused).
My hosting provider is having some technical issues with email, so I’m afraid I won’t be able to use the newsletter to notify people about this change.
