How do search engines deal with AngularJS applications?

Question

I see two issues with AngularJS application regarding search engines and SEO:

1) What happens with custom tags? Do search engines ignore the whole content within tho

Answer 1

The crawlers do not need a rich featured pretty styled gui, they only want to see the content, so you do not need to give them a snapshot of a page that has been built for humans.

My solution: to give the crawler what the crawler wants:

You must think of what do the crawler want, and give him only that.

TIP don't mess with the back. Just add a little server-sided frontview using the same API
