Make your website of record your website. Make social media platforms and others (e.g. Google) secondary to that. Don't let Google and Facebook control how you build your website. I am amazed at companies that take their websites and subjugate them to their Facebook page. You may gain social attention but you are handing over control. Never, ever, ever say to contact me go to facebook.com/xxxx or my email address is…
Looks like there's a typo in your first sentence. I could sort of figure out what you meant, but it took a bit of digging. EDIT: Never mind, I was straight-up wrong. Sorry!
> Make your website of record your website.
I don't see a typo (and your comment is 3 minutes more recent than his, so I don't think he made any corrections). Maybe "record" is throwing you off?
What he means is that "Your official or authoritative website (i.e., website of record, like owner of record) should belong to and be controlled by you."
Edit: If you're saying that the sentence could be hard to parse, yes I agree.
