You rarely see Google or Googlers that speak on Google's behalf recommend a specific SEO or SEO company. They give general and abstract guidance on how to hire an SEO but to say, here are some SEOs we trust - that is rare. That just changed when Gary Illyes of Google posted on Twitter calling out six different SEOs as "excellent, helpful, long time."
The context is that Gary read some SEO advice on the internet that was bad. Gary said, why don't you have other SEOs that are good out there peer review before you publish the stuff. So Gary called out six different SEOs as people you can ask for advice on your SEO articles.
Here are the tweets:
Just to name a few, in no particular order: @aleyda @randfish @dr_pete @Suzzicks @stonetemple @wonderwall7 2/2

I am sorry that so many of you didn't make the list. For those that did, congrats - let us know if this helps you with your consulting business.
In any event, the point is valid - don't publish stuff about a topic you don't know much about. If you do, get an expert to review it and edit it.
