Well, seeing as this one probably cost 4 to 5 (10?) orders of magnitude more than any gov website you may be thinking of…
We’ll probably never know the true “cost” of America.gov because even if Google is doing it “for free” then they’re not doing it out of the goodness of their hearts, there’s a regulatory angle that they’re trying to play or a market they’re trying to corner.
Non-interactive websites (that don’t even accept payments) are undoubtedly run on a shoestring budget unless there is a specific case of grifting or corruption. In which case we’re not talking about websites anymore but American grifting culture.
So you initially say 100k-1 million and then pull a 35 million dollar budget out…seems a little disconnected.
