As of Q2 2015, there is still no convincing evidence that social shares affect Google rankings.

You might want to read that again. Be it tweets, re-tweets, Facebook shares, or Google+ posts, there is just no solid evidence that they affect improvements in ranking positions.

In recent years there's been a big shift in the SEO industry. Search agencies and others are pushing the merits of content marketing as an activity that can help drive SEO success.

Among the inevitable increase in content, something being widely misunderstood and purposely misrepresented by some is the idea that social shares drive SEO results

Here I explore how the misunderstanding came about, why it might be convenient for some providers to allow it to persist and what is required to achieve that which does move rankings - links.

Why links work - the thumbs up concept

Central to search engine algorithms is the concept of citation. If an online entity is 'cited' by another popular and trusted entity then a ranking boost is given.

This is why links work. A link is a thumbs up by a third party and so it is logical that links are used in deciding ranking positions. 

As the use of social media has grown so it has seemed logical that a share - be it a tweet or a Facebook post of a URL - might also be seen as a 'thumbs up' and deliver a ranking boost. 

Is a share now the same as a link?

In 2013, studies from Moz and Searchmetrics revealed a correlation between shares and strong rankings suggesting that shares might indeed be used as a ranking signal.

However, correlation does not always equal causation...

In this Google Webmasters video from January 2014 Google's Head of Web Spam Matt Cutts states:

Google do not use signals from social media for search.

He goes on to say that "Google is limited in the amount of the social web it can crawl". I think this is an important point.

Google has become very efficient at crawling as many websites and webpages as possible, but clearly not so with social content such as tweets and shares.

Part of the issue is likely to be volume - the number of social posts on a daily basis dwarfs the number of webpages created.

If Google doesn't have the complete picture it can't use social shares as a ranking signal.

In a Google Hangout in August this year Google's John Mueller seemingly confirmed the situation.

When asked: "Do Social Signals have an impact on organic rankings in Google," his reply was a succinct: "Not directly. No."

So if Google is saying that social signals are not a ranking factor, what's behind the correlations observed in Moz and Searchmetrics studies?

It's likely that the correlation is actually because content that gets a lot of shares often has other signals that do drive rankings such as good user engagement.

It's these signals and NOT social shares that are causing the good rankings. 

On this basis social shares are just a by-product and not the goal for SEO.

If you're engaging in content marketing for SEO benefits you should be focusing on content that engages your audience and earns links not content that earns social shares. 

But content that gets social shares is going to get links as well isn't it?

No. It would seem that there's a very different dynamic that's at play between what makes someone share content and what makes someone link to content from their website editorial.

A recent study by Buzzsumo shows that there is no correlation between links and shares. A piece of content that gets shares will not necessarily get links and vice versa.  

To reiterate, the clamber for social shares just doesn't make sense from an SEO perspective.

So why is my provider reporting social shares as an SEO performance metric?

Two reasons:

1. Social shares are easier to achieve. 

The numbers can look good on reports particularly where links have been hard to come by.

2. Still acting on old, out of date information.

There was a period between the first ranking correlation studies and statements from Google representatives when the SEO community believed that social shares were a ranking signal.

Less-informed practitioners may not realise that this thinking has changed.

What if I expect my content marketing investment to help drive ranking improvements? 

If improved rankings are an objective then your content team should be achieving links and not focusing on social shares.

As mentioned there's a very different dynamic at play between what makes people share a piece of content via social media and what makes a website link to content.

It's more of an effort to link - provide a truly great reason

It is much easier for someone to whip out their phone and tweet or share a piece of content than for them to edit a webpage or construct a blog post or article to accommodate it.

Therefore to achieve links your content needs to be truly worthy.

Be it truly useful, truly informative, truly entertaining etc., it needs to deserve the effort required for someone to construct that link rather than just take the easy route of sharing on social.

Not everyone can link - identify those who can and build relationships

The number of people using social media to share content is exponentially more than the number of people creating website content on a daily basis.

It stands to reason that links are harder to come by than shares.

Part of your content marketing provider's remit should be identifying websites and writers that link to content in your niche and to build relationships with them.

Relationship building is a time consuming practise but is worth the investment. 

Ultimately, by linking to your content a writer is helping you out. They could have chosen to reference someone else’s content or nobody’s at all.

Would you do a favour for someone you’ve never heard of before? Probably not, unless that content was truly great - which takes us back to the previous point.

Identify link-worthy topics and content types

Analysis can reveal patterns in the topics and/or content types in your niche that are more heavily linked to. 

To be effective at achieving links this needs to be understood by your content marketing provider and worked into their strategy.

In summary 

If you're looking for your content marketing to drive ranking improvements you need links.

Links are what should be being reported on not shares.

Achieving links requires the content being produced to be truly worthy, a deep understanding of those who link in your niche and for your provider to be able to foster fruitful relationships with linkers.

Hi Chris, thanks for referencing the recent study I did on shares and links. It is true that in most cases shares do not drive links, people appear to share and link for different reasons. However, this is not to say shares are not valuable. In fact recent surveys suggest that more people discover content these days through social networks than search and that overall social now drives more traffic than search. Sharing can therefore improve your visibility and discovery through social networks but it won't of itself increase your links or SEO rankings.

Hi Steve,
Thanks for joining discussion. 100% agree about the value of social for amplifying your content and getting it discovered.

Hi there,

Just to echo what Steve said, social is great for visibility even if shares do not build links. Social also helps drive traffic to the site, increase engagement, time on site and enables us to re-target potential customers. Because of this it's still useful to report on social media, just not purely as an SEO performance metric.

Hi Angelina,
Again 100% agree. It is useful to report on social media for a whole number of reasons BUT not under the guise of something that is going to shift the needle re. organic search rankings.

Didn't the Moz/Buzzsumo research show that the vast majority of content was neither shared nor linked to at all? I think Moz's Rand Fishkin is right when he says even good content isn't good enough now. Content has to be at least x10 better than the competition in order to have any chance of having meaningful impact - either via social amplification or linking.

Hi Andrew,
Yes that's one of the takeaways from the Buzzsumo study. i.e a lot of content is in vain. Something that Rand Fiskin talks about is the need to create content that is ten times better than anything else. Another way of describing 'truly worthy' I guess.

Yes, when we took 100k posts at random we found the median number of shares was just 8 and the median number of referring domain links was zero. Sites like Moz and EConsultancy are very much outliers. It may be content isn't good enough or that there is simply no strategy to amplify. I was asked to look at an interactive web quiz today, the client and agency spent a lot of time and money developing it before the launch the other month, but it had no Twitter shares at all. So neither the client nor the agency had bothered to share it on Twitter and the web page hosting the quiz had no share button or way of sharing it. Lack of an amplifcation strategy is more common than you might think.

I'd say there's a skills gap re. outreach and amplification especially dare I say it with in house content teams. Anyone can have a go at creating 'worthy' content but not everyone knows how to amplify it effectively and get it discovered...
