Google has launched a Google Search Console Advisory Board, where they ask volunteers to join the board to give feedback on the Google Search Console.
This was 'outed' in the Google Webmaster Help forums where Miguel Borges-Porteous said he received an unsolicited email from a "Google SIMux employee" asking him to join.
Recently received an email message from a supposed Google SIMux employee, with an @google.com email address notifying of an opportunity to be part of a Google Search Console Advisory Board that is soliciting industry feedback for design improvements.
Needless to say, this would be rewarding to participate in, but a number of peculiarities stand out:
The sign up link goes to a google forms document (which could theoretically be put up by anyone)
The link uses google's link shortner goo.gl
He asked, is this a scam and the answer is no.
John Mueller from Google responded, "yes, this is legitimate." He added that this "went to a small, hand-picked group of Search Console users." If you are nervous, he said "one way to double-check the form is to look for the "This form was created inside of Google.com." in the footer. If you're interested, we'd love to be able to get your feedback on some of the ideas."
