There has been a tremendous amount of confusion around the news that Google will stop indexing sites that are completely inaccessible via a mobile phone after July 5th. Google will index sites that are not mobile-friendly – period. But if your site won’t load at all on a mobile device, it just doesn’t load period, then Google won’t index it.
Why? Because Google is fully switching to using its Googlebot Mobile user agent, and if you block that mobile user agent, which looks like an Android mobile phone, Google won’t be able to see your site at all and won’t index it.
It does not mean that if you do not have a mobile interface or if your not mobile-friendly, that Google won’t index it. Google will index desktop only sites, assuming that site does load on a mobile phone.
This is what I said in my original coverage but I see tons of confusion from people saying Google won’t index sites that are not mobile-friendly – that is simply not true.

Your site can still get indexed in Google Search after July 5, even if it’s not mobile friendly.
It’s been always the case that if googlebot can’t access a site at all (I.e. network or http error), the site couldn’t get indexed in Google Search. This will continue to be the case. The difference after July 5 will be that the site will need to be accessible to the smartphone user agent of googlebot. Whether the site is mobile friendly or not is irrelevant in this case, though it would be nice if it was mobile friendly.

Mobile indexing is unrelated to mobile-friendliness. A site can be mobile-unfriendly and be indexed completely fine.
