Effective influencer marketing campaigns are measured on an ability to pull an audience into action not just reach it. This is why influencer marketing engagement wins over reach.

Reach myth of influencer marketing
It's understandable that brands embarking on their first influencer marketing campaigns become seduced by social media stars purporting to shine via their stellar amounts of followers.
But, social media ‘influencers’ with large follower counts aren't always ‘influential’. Big is not always better. In fact, big is often just little wearing a fake nose and glasses.

WARNING: An influencer's theoretical reach might disguise low numbers of committed (or even real) followers.
In terms of the benefits of influencer marketing, why is size of an influencer's audience not always the best measure for generating effective results? Here are five reasons why reach is often a myth:
1. Fake accounts
An influencer's follower numbers may be comprised of a large proportion of fake accounts. Facebook may have as many as 137.76 million fake accounts according to technology news site, Venture Beat.
These fakes are what some social media specialists call “sock puppets”. Aleksej Heinze, Senior Lecturer and Co-Director of the Centre for Digital Business, University of Salford, wrote in the Conversation, a news source by academics and researchers, that these sock puppets are: “fake accounts of individuals pretending to be someone else. These online imposters often follow celebrities to make themselves look more authentic, along with other tricks that include constant automated re-tweeting and constantly following and un-following other users”.
The purpose of these sock puppets? To bundle up these profiles and sell them on to rubes wanting to increase their ‘influence.’

2. Buying followers and likes
It’s easy (and cheap) to buy these fake accounts. I’ve written before about the reach myth of influencer marketing. In past articles I’ve retold the story of Lena Katz and how her potato became a social media ‘influencer’ through the purchase of 10,000 Instagram and Twitter followers.
I also explain how a marketing firm in Sydney, Australia, won awards for its catering service … a hospitality company called Social Bites that didn’t exist. It’s a masterclass in building and marketing a fake product.

3. Follow back
Another trick in the cult of the audience-size-above-all-else is the You follow me, I’ll follow you back, ruse. Again, a numbers game. Everyday I gain around 20 new Twitter followers on spec. For half of them there’s never any message, or engagement. These new followers haven't liked, shared or commented on anything I've posted. I've not met them IRL.
I usually check out their bios and recent posts. If they’re not interested in the same range of topics I post about, I don’t follow back. Mostly these new subscribers soon become ex subscribers. If I don’t follow back within 48 hours they often unsubscribe.

The "I'll follow you only if you follow me back" tactic breeds large numbers of followers but little engagement.
4. Automating follower growth
The "I'll follow you only if you follow me back" moronacy can be automated, too.
Evan LePage added over 700 Instagram followers in six days by trialling Instagram automation leading providers Instagress and Instamacro.
Le Page achieved this vacuous following by automating the commenting functionality and associating different stock phrase comments with hashtags. He also automated his follower growth based on targeted hashtags in the hope the Instagram user would follow back. Le Page wrote about his experience for the social media management tool, Hootsuite, in an article I tried Instagram Automation (so you don’t have to).
4. Inactive accounts
Okay, so an influencer's audience may not be bots. They may not be fakes either. But is the following actually switched on? Do the subscribers, fans and followers ever actually, turn up and view the influencer's feed?
When was the last time you went on Google+? How often do log in to Twitter. Do you subscribe to YouTube channels and visit them for every new video?
Twitter is so concerned that active user numbers are stagnating - or even dwindling that the micro-blogging platform has stopped disclosing the percentage of its users who take "no discernable user action" on the app, making it harder for observers to figure out whether Twitter's core user base is growing or dying.
5. Algorithm
Research from Social@Ogilvy, suggests that for Facebook Pages with more than 500,000 Likes, organic reach could be as low as 2%. Fewer people seeing your Page's organic posts on Facebook means fewer clicks, comments, and shares. And having fewer of those interactions means fewer conversions, leads, and customers.

Influencer marketing engagement over reach
So, if the secret to success in influencer marketing doesn't lie in reach...

... where does it lie?
Yes, of course you need an audience to be influential. The secret of influencer marketing lies with finding an influencer (or influencers) with sufficient reach to meet your programme's objectives - but the real secret of influencer marketing lies in the influencers' pull. The ability for a creator to cajole a passive audience into action, to nudge them into doing something different. For best results with influencer marketing engagement wins over reach.

Influencer marketing engagement levels
Marketers trade cash for access to influencers' social capital. Social capital is more than follower numbers. It's a level of engagement. A sense of affinity between the community and the influencer.
At their core true influencers provide consistently compelling content and high levels of community engagement. Over time this helps them earn trust from their fans and establish themselves as credible voices.
Asked the difference between reach and engagement ZEFR co-founder/co-CEO Zach James told PRNewser:“ Reach involves passive participation, while engagement requires followers to be active. For example, if a person has 6.5 million Instagram followers, they have pretty large reach. But engagement refers to how many trackable actions happened as a result of someone seeing a given post.”
Reach and impression numbers as vanity metrics
Reach and impression numbers fall into the category of vanity metrics. They aren’t reliable engagement indicators. Neither are they a proxy for click through rates and conversions.
Being popular isn’t the same as being influential. Gaining large numbers of followers, impressions or visitors doesn’t necessarily translate into greater influence. A smaller, more targeted following may generate higher engagement.
In fact proportionally the greater the reach, the lesser the degree of engagement an influencer holds with her following.

Reach gives you potential numbers of eyeballs. Influence shows who is listening - and what action they're taking (RTs, shares, comments).
The benefit of using influencers is their ability to take your key message and craft it in a way that is more relevant to their audience (which should also be your client’s audience), so that it actually resonates with them.
If reach alone is your bag that can be replicated via amplification through SEM campaigns or sponsored social.
Shares and comments are great on social. Outside of social, though, I’m wondering, from the influencee’s perspective, what the “ultimate” sign of respect for the influencer AND brand would be. The elaborate answer is just a guess but it would be a multi-layered “sundae” of respect: Purchase+Video testimonial+Written UGC w/backlink+Social share+Comment (Purchase = Sale (from the brand’s perspective))
Hi Alex,
An influencer is someone whose voice resonates with his or her audience and who can stimulate that community to take action.
Influencers are change agents. They are people within a community who affect change be it purchase decisions, changes in opinions or altering behaviours.
The *ultimate* sign of respect from an ‘influencee’ in this instance would be to take action after having watched, listened to or read a piece of content created by an influencer.
So, yes, I think you’re right. But, the output of influence is dependent on the objective of the piece of content.
Thanks for reading and commenting @socialalex. Have a great weekend,
Scott
Yes but even so there’ll be ultimate high end behaviors within that.
