Google: Authorship Works With Google+ Vanity URLs

Once you get your authorship working, no one wants to mess around and change URLs. Some don't like to mess around even if the authorship is not live in the search results, in fear changing it might break something. This is even more so now that there was a reduction in authorship display in the results.

One question I get a lot from more advanced SEOs is should I use the numeric or custom/vanity URL from my Google+ page. Should I use the root or /about or /post URL as well? The answer is, it does not matter.
Google's John Mueller went on record about this topic this morning on Google+ saying:

I've seen this come up more since custom/vanity URLs for Google+ profiles have become more popular. Authorship works fine with vanity profile URLs, it works fine with the numeric URLs, and it doesn't matter if you link to your "about" or "posts" page, or even just to the base profile URL. The type of redirect (302 vs 301) also doesn't matter here. If you want to have a bit of fun, you can even use one of the other Google ccTLDs and link to that.

So there you have it, concrete information from Google on one of the scary topics to touch on.

Google: Your Various ccTLDs Will Probably Be Fine From The Same IP Address

Ever wondered if Google would mind if you had multiple ccTLD sites hosted from a single IP address? If you’re afraid they might not take kindly to that, you’re in for some good news. It’s not really that big a deal.

Google’s Matt Cutts may have just saved you some time and money with this one. He takes on the following submitted question in the latest Webmaster Help video:

For one customer we have about a dozen individual websites for different countries and languages, with different TLDs under one IP number. Is this okay for Google or do you prefer one IP number per country TLD?

“In an ideal world, it would be wonderful if you could have, for every different .co.uk, .com, .fr, .de, if you could have a different, separate IP address for each one of those, and have them each placed in the UK, or France, or Germany, or something like that,” says Cutts. “But in general, the main thing is, as long as you have different country code top level domains, we are able to distinguish between them. So it’s definitely not the end of the world if you need to put them all on one IP address. We do take the top-level domain as a very strong indicator.”
