Quick note:

Apart from organizing this article, I have never worked for or with Single Grain or Eric Siu. Eric has just been on my radar as a smart guy who would be fun to talk shop with.

This is a guest post on their site, but that doesn’t change my writing approach. This article is based on an interview I had with Eric along with publicly available information and research. The interview was great. After a few minutes of talking to Eric, it was obvious why Single Grain is so successful.

Single Grain's Story

Uber. Amazon. Airbnb. What do these companies have in common?

Well, apart from being household names, all of them have worked with one agency. You guessed it: Single Grain.

Single Grain was on the brink of closing in 2013, but they became the powerhouse they are today because of Eric Siu.

eric siu ceo of single grain growth everywhere podcast host

Eric bought the failing SEO agency in 2013 for two dollars. It was a “challenge” amid a partner exit crisis. Founder and chief lead source Sujan Patel was leaving, and the company wasn’t expected to last more than a few months.

That was more than 5 years ago. Now they’re 30+ strong and make 7+ figures in revenue. Not a bad turnaround.

Coming from the world of venture-backed startups and large corporations, Single Grain focuses on rapid acceleration via ROI-driven, experimental marketing. Sure, this isn’t a new approach to digital marketing, but being able to deliver isn’t always the issue. It’s about having a machine in place that attracts top-tier clients in the first place.

Agencies that get the best contracts usually have some or all of these assets:

  • a powerful content machine

  • a founder with a national personal brand

  • or previous connections that help them land their first big contract

Single Grain’s content marketing machine is fantastic, which is what Eric credits as their main lead generator. But they also have Eric. And Eric stays busy. :) Besides working day-to-day as Single Grain’s CEO, Eric works diligently to promote his personal brand as a thought leader and speaker.

He produces and hosts two podcasts, Growth Everywhere and Marketing School (co-hosted with Neil Patel), and speaks regularly at conferences. He is also piloting the recent release of his brand new SaaS product, ClickFlowsplit-testing for SEO. It offers clever ways to optimize your SEO, including title swapping and matching across keyword categories.

Needless to say, the guy is on top of things.

Let’s cover the big picture lessons that your agency can learn from Single Grain before digging into their funnel itself.

Lesson #1: The Power of Brand Multiplicity

Notice that Single Grain is just one (albeit the most profitable) component of Eric Siu’s business machine.

By structuring his services and products to provide value to one market (in Eric’s case, companies needing marketing support and digital marketers), he’s able to cross-pollinate across his ventures. This is known as brand multiplicity or brand stacking, and it’s the opposite of product market cannibalism.

Here are three examples of this in action:

  • One: Eric develops a relationship via a podcasting conference with a company that needs done-for-you marketing services, and he can lead them to the Single Grain sales process.

  • Two: If his latest Growth Everywhere podcast covers SEO split-testing, he can pitch his product.

  • Three: If he’s working with Uber and realizes they need to do some SEO split-testing, he can suggest adding his product to their SaaS suite.

See how that works? When you create a spread of valuable services across a similar topic, they all benefit from each other. An easy way to think about brand multiplicity is by taking a close look at your value ladder.

Take a second to think about your current service or product offerings. Then ask yourself these questions:

  • How many of them directly relate and fit in with each other?

  • Is it possible to rebrand them or adjust the content/delivery method to better complement your other services?

  • What services or products are you currently developing? Where do they fit in?

Before we dig in to what your agency can learn from Single Grain’s content marketing machine and overall funnel, let’s talk about the long-term rewards of content marketing.

Lesson #2: The Exponential Nature of Content Marketing

Content marketing is creating, publishing, and distributing content to a specific audience. It has many forms, but we’re all familiar with the most common mediums: video, podcasts, blogs, etc. Nothing new here. :)

But what many people forget is that content marketing follows an exponential curve:

Exponential content marketing


Whether you start releasing videos on YouTube, blogging on your website, or hosting a podcast, the first thing you need to know is that growth will be slow. But that’s expected — even for people with an existing audience. (Check out this article about why you should build an audience first).

Most people burn out after a year, but if you are one of the few who pushes through, the eventual benefits will be a long-lasting asset for your business. If you want proof of this curve, look no further than Eric: Eric averaged 9 downloads per episode in the first year of Growth Everywhere and 30 downloads per episode in the second year.

He averaged about six hours of work per episode as well. Think he thought about giving up? God yeah! :) Here’s the thing, though: as you get better, your audience will grow. Getting started in content marketing sucks. Your content kinda sucks. You suck. It doesn’t matter who you are. But it’s okay. :)

As you hone your craft, you will build yourself toward a tipping point. Once crossed, your subscribers, views, or visits will begin climbing. Then you can capitalize.

[bctt tweet="Content marketing compounds over time and your initial investment of effort will be rewarded. IF you stick to it." username="singlegrain"]

Eric and his team didn’t see promising results until the third year. Nowadays, Growth Everywhere gets over 80,000 downloads per month. Keep that in mind as we start digging into the actual breakdown of Single Grain’s funnel.

Lesson #3: The 3 Essential Components of Modern Marketing Funnels


When building a marketing funnel, it’s helpful to split your efforts into levels or stages. This framework helps focus your effort and provides insight into bottlenecks, what type of content fits where, etc.

The three levels are most often described as:

  • Top of the Funnel (TOFU)

  • Middle of the Funnel (MOFU)

  • Bottom of the Funnel (BOFU)

If any of you are familiar with HubSpot and inbound marketing, they refer to these three stages as:

  • Awareness

  • Consideration

  • Decision

We’re going to cover each stage of Single Grain’s funnel so you can install it in your own agency.


[bctt tweet="TOFU is the content that introduces people to your brand and makes them aware of the problem they have." username="singlegrain"]

Examples of content:

  • Blogs

  • Webinars

  • Podcasts

  • Conferences

  • Advertising, etc.

You can think of TOFU as everything that exposes people to your brand. It’s the first step. This is where your content empire is born. :)

It’s blogs. It’s podcasts. It’s billboards. It’s radio interviews. Whatever content you’re using to find new people, then it fits here.


[bctt tweet="MOFU is the content that explains your style of solution to the prospect and why it’s the right way to solve their problem." username="singlegrain"]

Examples of content:

  • In-depth blogs

  • White papers

  • Emails

  • Advertising

MOFU is after a prospect knows about their problem, but they’re still researching the best solutions. For example, for the problem of getting more traffic to their website, they could be torn between podcasting and blogging.

Here’s another example: Someone is struggling to hire people. They are deciding between hiring a recruiter and hiring an internal HR director. Simple stuff. This is when you use your content to explain why your solution (not your company!) is the best route to take.


[bctt tweet="BOFU is the content designed to convince people why YOUR agency specifically is the right choice for them." username="singlegrain"]

Examples of content:

  • Case studies

  • Demos

  • Advertising

  • Deals, discounts

BOFU is when you make the case for your company to provide the solution they discovered in the MOFU stage. It’s also when you tell the prospect why they should work with your company instead of a competitor.

Jumping to this stage too early is a common mistake in marketing, as is waiting too long to get people here. Finding that balance takes tweaking and experimentation, but the conversion rates you’ll reach are worth the effort.

Note: Depending on your copy and CTA, you could make any type of content fit into any stage.

Now let’s see how Single Grain uses these levels in their own agency.

Single Grain’s Funnel Part 1: TOFU Growth Machines

2 1

Single Grain splits their TOFU efforts across three major mediums: podcasting, blogging and video. Remember: TOFU content is all about building brand awareness and decreasing your cost per lead. We do this by attracting more inbound conversations.

When starting a content marketing strategy, it’s useful to pick one medium and stick with it. Try them all out at first, see which ones feel the most comfortable, then go from there. Once you start to see some results, then you can consider diversifying.

Single Grain now works in podcasting, blogging and video simultaneously.

TOFU Growth Tool #1 - Podcasting

Growth Everywhere page

Eric started his podcast with no experience or audience. At the beginning, he spent six hours creating each episode. All this effort got him a grand total of 9 downloads per episode. For the first year.

Again, content marketing takes time, but the end results are worth it. Eric has released hundreds of podcast episodes via Growth Everywhere and Marketing School. Here are some of the major lessons he’s learned along the way:

Use Batching to Your Advantage

Eric and the Single Grain team are fantastic at batching their content efforts.

Batching is just what it sounds like: Instead of recording and releasing each episode one after another, Eric schedules a bunch of interviews and builds up a bank of content to pull from. We do this at Wild Audience as well, and it makes a big difference. :)

Consistency is king, so you never want to be scrambling for content at the last minute. This will diminish your quality and could jeopardize your reputation.

This applies to blogging and video content as well. Take Marketing School, for example. The show releases daily and runs around 5 minutes per episode. In order to handle the high frequency, they meet in an L.A. studio 1-2x a month, brainstorm 15-20 topics, and then knock them out one after the other. The same goes for Growth Everywhere. Eric is currently set all the way up to February of next year.

Don’t Advertise too Early

[bctt tweet="Quality should always be your focus, so wait until you have an active and engaged audience before advertising." username="singlegrain"]

One of the biggest mistakes you can make is advertising too soon in your podcast. You don’t want to poison advertising relationships too early or bug your subscribers too much to get advertising impressions up.

Use the Right Tools

You don’t have to have the best equipment to start podcasting.

All you really need is something like Zoom or VCAM for interviews, a basic mic, and a tool to start your outreach with (Eric used

Remember that ROI Is Exponential

The ROI of a podcast is exposure and authority, which leads to a devoted audience. Which leads to more sales for your other businesses. Which leads to speaking gigs. And because podcasting is so intimate, it shortens the sales cycle because leads feel like they already know you.

TOFU Growth Tool #2 - Blogging

Single Grain blog

When it comes to Single Grain’s content machine, blogging is probably the most important part. Eric gets more leads from organic traffic than anything else, and this includes all of the flagship companies he’s worked with (Uber, Amazon, etc.)

Here’s the thing about blogging:

[bctt tweet="Blogging is a direct demonstration of your agency’s thought process and expertise." username="singlegrain"]

Smart business leaders recognize talent when they see it, and Single Grain uses high-quality content to demonstrate authority and expertise before a sales call ever happens. This reduces your sales cycle time and brings in higher-quality inbound leads because they already trust you.

Look, the days of keyword stuffing and 300-400 word blogs are over. :) There’s no point in doing this unless what you’re putting out is better than your competitors. When you have longer-form posts, you get more long-tail keyword traffic. This gives you more domain authority and pushes your rankings higher and higher.

Single Grain aims for 1,500-2,000 words per blog. Minimum.

If you’re serious about competing, you need to develop a strategy, do your keyword research, and write better content around it. It’s simple, but that doesn’t make it easy.

Take a look at how Single Grain organizes their blog. They use a combination of in-depth guest posts (*cough cough*) and collaborative pieces to rank for the exact keywords they want to.


Their blog is well-designed, and they are always testing new headlines and content upgrades/lead magnets.

More on that BOFU content upgrade later. :)

When the Time Is Right, Get a Team

Writing, editing and promoting are each separate positions in an active and effective content marketing machine. If you want to expedite your results and you have the capital to do so, consider investing in a team and building up those processes earlier on. This isn’t a requirement, though. Eric started on his own, and there is a lot to be learned from sucking it up and doing it yourself. Once you see traction, you can start to delegate.

Don’t Underestimate the Importance of Proper Keyword Research

Blogging is dramatically less effective without keyword research. It doesn’t matter how good of an article you write; if people won’t see it then it’s pointless.

Find out what your competitors are up to, see which keywords you could write better content for, and get to it.

Standardize Your Process with a Blogging Checklist

This is more important once you have a team behind you, but you should use a blogging checklist to ensure that everything you release is optimized. This should include steps covering content, SEO, and how it fits into your funnel.

Take Advantage of Guest Articles after You Have an Audience

Once you have a devoted audience of readers, you can lighten the content burden by featuring other writers you trust. They get exposure, a strong backlink, and sometimes payment, while you get content that is interesting to your audience and gives you a bit of a break.

Understand and Use the Success Gap

A success gap is the knowledge and tools your ideal customer needs to be successful. Just because something isn’t directly related to your product doesn’t mean it’s not worth talking about.

For Single Grain, talking about sales is important because their customers care about sales. It’s not marketing, but this widening of the net is a great way to pull in more traffic after you’ve become an authority in your niche.

TOFU Growth Tool #3 - Video

Growth Everywhere YouTube Channel

Video is Single Grain’s latest content venture. They currently have a YouTube Channel with 13k subscribers and are hoping to grow that past 100k. :)

By utilizing batching, Eric is able to spend the same amount of time producing new content while growing an entirely new channel. This taps in to the idea of content multiplicity.

[bctt tweet="Content multiplicity, also known as circular viralocity, is the strategic repurposing of existing content across different channels." username="singlegrain"]

By taking the same piece of content effort and spreading it across as many channels as you can, your agency can make your content go a lot further. Think about it. By recording just one podcast episode on tape, Eric can:

  • Release a video of the podcast

  • Turn the podcast into multiple blogs

  • Stitch together clips from that and other videos to create a montage around a particular topic

  • Release the audio of the podcast on all podcast platforms + Spotify & SoundCloud

  • Take a portion of the blog or main topic and add it to their email automation sequence

And on and on and on.

MOFU: Evergreen Email Sequences, Ads & Inbound Opportunities


So getting your brand in front of someone is one thing, but getting them to give you an email address or hop on a call is another. TOFU content is only the first piece of the puzzle. What goes on behind the scenes is also important to create and test.

Single Grain has tried it all — separate funnels for each persona, personalized emails, you name it. Here’s what your agency can learn from their system:

Use the Power of a Long-Form Evergreen Automation System

Here’s the deal. Emails lose value if you aren't consistently engaging with them — especially at the beginning of a relationship.

Single Grain has landed on an interesting approach: enroll leads in a 52-week email automation. An entire year’s worth of educational material. For Eric and his team, they decided they were spending too much time on MOFU personalization and decided to put most of their efforts into TOFU.

Sure, having more personalized MOFU content could increase conversion rates, but running an agency is all about prioritizing efforts.

To make the MOFU burden lighter, Single Grain created one funnel that drips evergreen content and CTAs for an entire year. They built it by reusing their best blogs and podcasts, and they pair the emails with an RSS feed that sends the latest blogs, news, etc. to keep things fresh.

Single Grain Opted for One Super Signature and a Few Main Content Offers

Single Grain used to match individual lead magnets to blogs and tweak their email sequences to better fit customer segments, but they’ve left this approach for something more manageable: a one-size-fits-all approach to email signatures and lead magnet offers.

Single Grain Lead Magnet

This is the default sign-up box on their blog. They only have a few of these and swap them out according to the general topic (SEO, blogging, etc.). So instead of matching a lead magnet to each blog specifically, they have a few strong, broad lead magnets.

After you sign up, you get a webinar upsell along with some segmentation options with more specific lead magnets or white papers:

Single Grain upsell page

Their webinar pitch is short and sweet and relies on Eric’s personal brand, and they tease a bonus for segmenting themselves.

Once you choose your persona, you’re directed to a bonus page that encourages you to share one of their TOFU pieces.

In this case, it’s the Marketing School podcast:

podcast sharing prompt

Then the lead receives the bonus in an email and is enrolled into their automation system.

This is the same automation mentioned above, and these emails always include what Eric calls a "super signature".

Check it out:

Single Grain Recurring Email

In the same email, Single Grain pushes:

  • TOFU (Podcasts/YouTube)

  • MOFU (webinar)

  • BOFU (consultation)

  • His related software (ClickFlow)

  • His services (done-for-you)

  • And more

Single Grain saw that qualified leads were getting stuck in the “give” part of the TOFU funnel, and they decided to allow people to move at their own pace.

Take some time to look over your own email funnel and see if anyone could be caught in content purgatory.

Front Load Content and Use RLSA Ads to Dramatically Increase Your Leads for Cheap

One type of advertising that Single Grain uses in both MOFU and BOFU circumstances are RLSAs (Remarketing Lists for Search Ads), and Eric credits them for a lot of Single Grain’s leads.

The idea is simpler than it sounds: when someone reads or visits the Single Grain site and then searches for a particular keyword later on, Single Grain displays an ad. If someone on your site reads a blog about SEO and then Googles “seo consultancy”, you want to be in those results.

Single Grain and their surrounding businesses currently get around 140,000 visits per month. That’s a lot of traffic to pixel and retarget to! :) If Single Grain were to pay for their traffic on an annual basis, it would cost $4.5 million dollars. Probably more, but that’s the power of organic content. It gives you leverage and you don’t have to rely strictly on PPC — instead, it empowers PPC.

In other words, content marketing “lifts the entire boat.” It helps you build email lists for cheap and your CPA goes down because people already know who you are. By combining their TOFU content’s traffic and PPC, Single Grain is able to collect email addresses as low as $1-$2 a pop.

That’s a heck of a tool for your agency to develop.

BOFU: The Prize

Add subheading

Now for the good part. :)

[bctt tweet="BOFU content is all about WHY a customer should pick your business." username="singlegrain"]

For Single Grain, most of the work is done for them at this point because they often include BOFU content all around the site. They are always offering their free consultation, pitching their SaaS product, offering next steps in their super signatures, etc.

Free consultation homepage

All of their sales conversations are inbound. Single Grain reps never cold-call people, ever.

If a prospect wants done-for-you services, they just fill out a qualifying form and one of the sales people will call, discuss the project, qualify the lead, have a proposal conversation if needed, and then go from there. They have account executives who specialize in closing and sales account representatives who only conduct discovery/qualifying calls.

All of Single Grain’s sales positions are in-house, and their average close rate from discovery call to close is 15-20%. Not bad! :)

Here a few things you can learn from Single Grain’s BOFU/sales section:

Single Grain’s Sales Zap

They use Zapier to push inbound notifications to Slack, their CRM (Base), a Google Sheet, a text and an email to Eric. This saves them a bunch of time and lets them reach out immediately.

Single Grain’s Main Offer

They sell most often from inbound leads who attend their webinar, and that webinar sells a bundle. This bundle includes:

  • an SEO course

  • a how-to-hire course

  • a content marketing course

  • ClickFlow

Single Grain’s top package sells for $16,000, and that includes what's above, plus three strategy calls with Eric and placement on the waiting list to work with Single Grain. Yeah. Single Grain has so many inbound leads they need a waiting list. :)

The beauty of their system is that Single Grain can upsell or downsell depending on the user, and they have a variety of bundles at different price points — even offering their courses a la carte.

Next Steps: Using Single Grain’s Strategy in Your Own Agency

So what do you get for all of this work writing blogs, starting podcasts, building amazing lead magnets? Why go through the trouble? What’s the prize?  

Let’s remember what happened with Single Grain. :)

  • Growth Everywhere started at 9 downloads per episode in the first year…

  • Now they are at 80,000 downloads a month...

  • Eric bought Single Grain, a digital marketing agency, for $2...

  • Now they pull in 7 figures (and growing), and they have a waiting list of companies wanting to work them...

I think it’s safe to say their system works :)

Here’s a quick recap:


If you’re struggling with where to start, first I’d pick up the blogging checklist: DOWNLOAD SINGLE GRAIN’S BLOGGING CHECKLIST
