We’ve been running our content marketing agency, Grow and Convert, for 6+ years now. In that time, we’ve worked on content writing and SEO strategy for dozens of clients, including SaaS businesses, B2B service businesses, and B2C companies.

From several years of experience, as well as countless conversations with other businesses doing content marketing (both in-house and with agencies), we’ve developed a good sense of what businesses are looking for when they hire content marketing agencies, what they’re disappointed by in the ones that don’t work out, and what true growth looks like in a successful engagement. 

So, to help businesses choose the right content marketing agency, we’re going to share our most important learnings and the key factors that you should consider when evaluating different content marketing firms.

Then, we’ll share how we’ve addressed each of these factors at our agency. And lastly, since most companies like to evaluate multiple agencies, we’ll share the best content marketing agencies we’ve heard come up a lot over the years (including ours).

Below, we cover:

Note: Many companies wonder if they should hire an in-house marketer instead of an agency. We discuss the pros and cons of both options in this post

4 Factors to Consider When Evaluating Content Marketing Agencies

To begin, we’ll cover the 4 biggest factors you need to consider when evaluating agencies:

  • Factor #1: What’s your content marketing goal?

    For example: website traffic growth, email newsletter growth, leads and sales — e.g., calls to discuss your service, trials/demos for SaaS companies, product purchases in eCommerce.

    And is the agency’s content strategy optimized to achieve that business goal?

    This is the #1 factor you need to be clear on. In our experience, most companies want leads and sales — i.e. real customers and measurable ROI! — while most content agencies are built to grow traffic and email marketing lists. This mismatch causes problems.
  • Factor #2: Do they have a process for gaining product and domain expertise, and expressing that through content?

  • Factor #3: Do they have processes to actively promote the content they produce?

  • Factor #4: Do they have detailed case studies that demonstrate the effectiveness of their strategy?

Let’s look at each of these in more detail.

Factor #1: What’s Your Goal From Content (Traffic, Emails, or Leads and Purchases)? And Is Their Content Strategy Optimized to Achieve That Goal?

Companies have different mindsets regarding the goal they hope to achieve from content marketing. In our experience, most want leads or sales — whether that be eCommerce purchases, sales call signups, or trials and demos in SaaS — because they want measurable ROI out of all their marketing channels, including content. This makes sense.

But there are some, for example, later stage companies with existing large lead generation numbers, that may want to use content for traffic and email signup growth. Others just have a vague idea that they want to do inbound marketing, and may not even realize that this is a choice they can make (i.e. they assume content is solely for getting traffic and brand awareness).

The first thing to understand is that this is a choice. You can optimize content around metrics like website traffic and email signups (what most digital marketing agencies do), or you can optimize content for generating leads and sales (what our agency does).

If you just want website traffic to grow your online presence, it will be much easier to find an agency whose strategy aligns with your goal.

However, most businesses ultimately want to see ROI from content, which means seeing leads or purchases attributable to content and meaningful increases in revenue over time.

In our experience, this requires a very different content marketing strategy (like the one that we use and have explained at length in previous articles like this and this).

That’s why we think this is the first and most important consideration when evaluating content agencies: Know your goal and figure out if the agency’s strategy and process is built to satisfy it.

If your goal is customer acquisition, then ask the agencies you evaluate if that’s what their strategy is optimized for. Ask them to be very explicit about this:

  • Is their process designed to produce content that gets leads and sales?
  • How does it work to actually achieve that goal?
  • Are they data-driven and can they prove that their process works?

If an agency is asked if their process produces leads and sales, they’re obviously going to say yes, so you have to be very specific in your questioning. Focus on the second and third questions above, see if they can explain exactly how their process generates service signups or product purchases (not email signups, those are very different). Use your gut instinct — if you can’t figure out how their process will get leads or sales to increase, it probably won’t.

The biggest complaint we hear from companies who’ve had bad experiences with agencies — and frankly, the biggest complaint we had in our past experiences working with agencies — comes down to misalignment between what the agency optimizes content for, and what the company actually wants. So don’t skip this factor.

Factor #2: Do They Have a Process for Expressing Product and Domain Expertise Through Content?

Second, regardless of what your content marketing goal is, it’s important for whoever is producing your content to be able to express domain expertise in a way that feels native to your brand.

This is especially true for B2B businesses whose target audiences are often advanced industry experts who need to be communicated with at an expert level. If you don’t speak to them at their level, you risk reputational damage and turning off potential customers.

However, expressing product and domain expertise is important in B2C, too. Particularly if you choose to optimize your strategy for leads and/or sales, the topics you’ll write on will be very product or service-centric. This means whoever is writing your content will need in-depth knowledge of your product or service, the nuanced pain points that they solve for customers, and the ways in which your product is differentiated from competitors.

Most outside agencies or freelance writers will not have this product and domain expertise, and therefore need to have a process for getting this information out of the minds of the experts at your company, and expressing it through your content.

With that said, what we’ve seen in the market is that many agencies and freelancers end up doing what we call “Google research papers.” Like a high school student doing a research paper, they Google around the topic they were given and regurgitate what everyone else is saying on a given topic.

Instead of producing engaging content, this is undifferentiated and generic. So, when evaluating agencies, make sure you ask them:

  • What is their process for being able to write and convey your value props, benefits, messaging, and differentiators in a way that feels native to your brand?

  • Do they even have one? And if so, how does it work?

Is it a one-off interview at the beginning of the engagement? Is it a few one hour calls? Do they regularly interview experts at your company on a piece-by-piece basis?

We have found the latter approach — doing interviews on a piece-by-piece basis — to be both extremely rare when working with outside agencies, yet the most effective approach for expressing product and domain expertise through content. This is the approach we take at our agency and what we think differentiates good and great content, which we’ll discuss more below.

Factor #3: Do They Actively Promote the Content They Produce?

Content writing is just one facet of the content marketing process. For content marketing to work, it’s also necessary to do content promotion. This is what drives actual traffic to your articles.

So, another key thing to understand is what the agency offers with regards to content promotion. Is it included in their service? Sold separately? And what exactly do they do?

For example, do they just share the content they write via your own brand’s social media marketing channels (tweet it out for you, share it on your LinkedIn page, etc.)? Because that’s something you could easily do yourself.

Or, if they rely strictly on search engine optimization (SEO), is there anything they do in the short term to help drive traffic to articles during the time it takes for them to rank?

This is a key issue to address because what an agency offers for promotion will determine how much you’ll need to do on your end to drive traffic to your articles.

Ensure They Don’t Use a “Keyword Sprinkling” Strategy and Call That SEO

We’ve spoken with several clients who’ve had bad past experiences with SEO agencies. And after digging into the content those agencies were producing, we’ve learned that they often use a “keyword sprinkling” strategy.

Essentially, they’ll create “SEO” articles by simply “sprinkling” a bunch of keywords throughout their articles. But as we’ve explained in our article on SEO content writing, ranking highly for valuable keywords takes a significantly more strategic approach than this. Specifically, for the most valuable and competitive keywords, you need to have one single article or landing page completely optimized for a single keyword.

If an agency says that they primarily rely on SEO to drive traffic, be sure to have them explain to you how they go about ranking content for specific keywords. Ask them:

  • What’s your process for doing keyword research?

  • How do you choose keywords to target?

  • What’s your process for analyzing search engine results pages (SERPs)?

  • How do you reflect those analyses in your writing to get articles to rank?

  • Can you show us examples of articles you’ve written that are ranking highly in Google?

  • Are you doing digital PR or building high-authority backlinks to the articles?

Content or SEO services worth hiring will be able to answer these questions in detail and show you results they’ve gotten for other clients.

Note: We’ve published a detailed article on our SEO writing process, which you can read here. We’ve also published a detailed case study on SEO rankings data from 20 active and former clients, which you can read here.

Factor #4: Do They Have Detailed Case Studies That Demonstrate the Effectiveness of Their Strategy?

It’s very common for content marketing companies to share a lot of theoretical advice and information, but show little to no data or case studies that back up what they say and prove that their strategies work. It’s also common for them to put up badges about having “award winning” digital marketing services, quotes from past clients, or random stats like “we grew X company’s organic traffic by 200%.”

These types of testimonials and unsupported claims are not reliable proof that an agency can do what they say. So, an essential thing to look for is whether or not an agency has published the results they’ve achieved for clients, and specifically explained the details behind how they achieved those results.

Otherwise, you just have to blindly trust their level of competency, which leads to very inconsistent experiences with agencies.

When reviewing agency case studies, look for details about the work behind the results. For example, if they’re claiming they increased traffic by some percentage for a past client, figure out:

  • How many articles did it take?
  • Did one article produce most of that or was it spread out?
  • What keywords did they rank for?
  • How and why did they choose those keywords?
  • How long did it take to rank?
  • What was the domain authority of that client at the start and end? Did they do link building?
  • What didn’t work?

The more transparent agencies are with the results they’ve achieved and the ways in which they got those results, the more you can trust them to be able to replicate those types of results for your business.

Now, let’s walk through how our agency has addressed each of these factors, including the details of our content marketing strategy, our writing and promotion processes, and 6 long-form case studies we’ve published to demonstrate the effectiveness of our strategy.

1. Grow and Convert: How We’ve Addressed Each of These Factors

#1. Our Content Strategy Is Optimized to Drive Leads and Sales

We’ve optimized our content marketing strategy to drive leads and sales (versus traffic and email signups) for two key reasons:

  1. Most companies want to see ROI from content: Sooner or later, most brands that invest in a content agency want to see some form of measurable ROI. We learned early on that if we can show ROI to clients (in particular management and executive teams), the engagements last longer, allowing results to compound while making everyone happy.

  2. There’s likely a significant volume of people actively looking to buy the product or service you sell: For almost every business, outside of rare category-creating products, there is some significant volume of people who are actively looking to buy that type of product or service — or solve pain points that product or service solves. These people are Googling terms that indicate they are ready to buy. Our perspective is that it makes way more sense from a business standpoint that a content strategy goes after these ready-to-buy-now people first (where conversion rates are much higher), before trying to reach the people higher in the funnel.

We’ve written at length about how we drive leads and sales through content for different business types. Check out these articles for detailed walkthroughs on our philosophy and our process:

Our Philosophy on Content Marketing Strategy

B2B Content Marketing Strategy

SaaS Content Marketing Strategy

B2C Content Marketing Strategy

How We Hold Ourselves Accountable

For every one of our clients, we create an ROI graph like this one (a live graph from a B2B SaaS client we’ve been working with for over 2 years):

Leads from G&C Content and Conversions over time

The horizontal lines represent the number of leads this client needs per month to break even on their monthly spend with us. Each month, we plot the number of leads from our articles on this graph. Then we report on our progress in relation to that break even number, so clients can see when they begin to have positive ROI.

We’ve written extensively about how we do this here and here, including more case studies and client data. Before we started our agency, this is the type of thing we were looking for but could never find. And we feel this is the number one differentiator of our agency.

#2. We Use an Interview-Based Writing Process to Express Product & Domain Expertise Through Content

We don’t produce articles in the “Google research paper” style we described above (self-researching a topic and writing what you find).

Instead, our writers start by interviewing people inside your organization who have the know-how and expertise to speak on that topic and convey how your product and your company has innovated or differentiated itself in the topic area of the article.

Thus, the writer is not asked to pretend to be an expert themselves. This is a massive shift from traditional content services and is essential to producing genuinely high-quality content.

We’re not talking about grabbing a few quotes from experts to throw into an article. We’re talking about hour-long recorded interviews where we shape an entire article around the viewpoint and knowledge of an expert inside your company, who can not only speak to the topic area but also tie-in your product.

This changes everything. It creates true thought leadership content, and adds genuine product expertise into our articles because we’re able to include copywriting on all the detail and nuance of how your product or service is differentiated, what it replaces, why features were designed in certain ways, and more that only experts inside your company would know.

#3. We Use a Two Pronged Content Promotion Process

We use a two pronged promotion strategy to drive both short- and long-term traffic to your articles as we wait for them to rank in Google. Specifically:

  1. Paid ads / PPC marketing campaigns (short-term traffic): We use paid ads to promote content using two targeting methods: Cold audiences (using interest and demographic based targeting) and lookalike audiences (based on the client’s existing customer list or website visitors). We test paid channels such as Facebook, Twitter, Linkedin, and Google Ads — based on each client and where we’re most likely to reach their audience.

  2. Manual link building (long-term traffic): When certain pieces start ranking for their keyword, we strategically deploy link building to boost them to page 1 — or the top of page 1 — in Google.

The combination of these two steps gives our pieces a short term boost in traffic followed by long term sustainable organic traffic that adds up from different articles and grows over time.

We do all of the above from our own budget, with no extra spend for our clients, making us a truly full-service agency. This is markedly different from other top content marketing agencies and something we’re very proud of offering our clients.

#4. We Publish Detailed Case Studies to Demonstrate & Prove the Effectiveness of Our Content Strategy

Here are 6 in-depth case studies we’ve written to demonstrate how we’ve executed our content strategy for real businesses:

  1. B2C content marketing example: How we grew Cognitive FX to 70,000 pageviews in 14 months

  2. Content marketing case study: How we scaled Leadfeeder’s signups to over 200/month

  3. Scaling content: Expanding from bottom of funnel content to top of funnel (Geekbot case study)

  4. Scaling SEO traffic from 920 to 14,577 sessions in 6 months (Circuit case study)

  5. How to do B2B content marketing without domain expertise (Rainforest QA case study)

  6. How to create a keyword strategy for a new, innovative product (Case Study of a video editing software client)
