Google effectively euthanised its Authorship experiment last August. But content marketing expert Eric Enge has come up with eight rock-solid reasons why author authority still matters, even if Google isn’t formally measuring it.

When Google’s Panda and Penguin began their excursions through the Web, everyone involved in content creation knew about it. These were major algorithm changes that altered the world of SEO irretrievably, much of it for the good. We knew about these changes not only because they were palpable (sometimes painfully so, in the form of massive drops in rankings), but because Google also announced them, albeit often after the event. But that’s almost certainly not the way things are going to be from now on.

If you haven’t already started, it’s time to prepare: if your website isn’t mobile friendly by 21^st April, you can expect to be clobbered, even if the content of your articles or video production is top quality and you haven’t used any manipulative backlinking methods. Google’s new mobile friendly algorithm kicks in on that date.

So now we know, courtesy of the Wall Street Journal: Google is to build a new augmented reality OS based on Android, and it’s already assembled a team of engineers to do it. The search colossus, it seems, has thrown the gauntlet firmly at the feet of Microsoft, Samsung and Facebook.

In the context of another tech boom, Apple has decided to bring the majority of its contract security staff in-house as permanent, full-time employees, according to a recent media report in The San Jose Mercury News (Apple is based in the Cupertino area just west of San Jose).

It’s hard to believe it, but 24^th February 2015 marked the fourth birthday of Google’s Panda algorithm: Panda 1.0 debuted on 24^th February 2011. Yup, it’s been with us that long. And it’s hard to dispute that it represented the most significant content quality algorithm the search giant has ever released, including Penguin.

Google’s recent move to label websites according to how mobile friendly they are is “a game changer for digital publishers”, a mobile marketing expert has claimed.

Rumours began to spread earlier this month that Google had updated its search algorithm but the speculation looks set to continue: the search titan still hasn’t confirmed that a change has occurred.

Bloomberg has reported that a significant partnership has been struck between Google and Twitter that will see real-time tweets from the latter reinstated in Google’s search results.

Back in November, Google confirmed in its Webmaster Central Blog that it was experimenting with a special ranking algorithm for mobile-friendly websites; last week, evidence emerged that it has indeed released a new mobile algorithm.
