Ask HN: How does Twitter do SEO if their site renders using JavaScript

At one time, and probably still today, Google pays for a "firehose" direct feed from twitter.

Oh actually

Another point is a lot of the big sites don't even bother with SEO (or standards for that matter) when they get that big.

Yeah. I bet Google assigned some folks the task "make a twitter crawler"

Google does index JS pages.

It's not that hard to do, I've used

to do just that.

Yet try to search your twitter username on google.

When running a walled garden the lack of SEO is a feature.
