Quick Summary 

We researched 20 top SEO copywriting agencies that help drive conversions (demos, signups, etc). Our top picks include Embarque, Writing Studio, Brafton, and Verblio. Read on to discover why we picked these agencies and learn about their pricing, services, results, etc.

Want to find the best SEO copywriting agency for you?

Good SEO copy does 3 things: 

  1. It gets you found
  2. Keeps people hooked
  3. Drives conversion. 

But pulling that off consistently takes repeatable frameworks, solid strategy, practice, and a whole lot of experience under the belt. That’s where a good SEO copywriting agency makes all the difference.

In this Embarque article, we’ve rounded up 20 top SEO copywriting agencies that know how to create high-converting content. 

But first…

Why listen to us?

We’ve worked with enough businesses to know what excellent SEO copy looks like. That’s how we’ve helped MentorCruise grow revenue 16x year over year and helped Cleanvoice boost MRR by 300%. 

So when we say these agencies are good, we’re not guessing. We’ve seen what works, and this list is based on who can move the needle.

Why hire an SEO copywriting agency?

They bring in traffic that actually matters

It’s easy to get traffic. It’s harder to get the right traffic. SEO copywriting agencies focus on ranking for keywords your target audience is actively searching for—the kind that ties directly to what you offer. 

For example, Embarque helped BlueTally grow from just 52 to over 7,600 monthly visitors, a 14,637% increase. And it wasn’t random traffic. It was high-intent and product-aligned and helped drive business growth.

They save your team hours every week.

SEO copy takes time. You need research, strategy, writing, editing, and optimization—and that’s before publishing. A solid agency takes that off your plate so your team can stay focused on product and growth. You still get high-quality content but without the back-and-forth or missed deadlines.

They write with both people and Google in mind

Ranking is one thing. Getting people to stick around and engage is another. A good SEO copywriting agency knows how to do both. They structure content for search intent, but they also make it easy to read, clear to navigate, and built to answer real questions.

They turn visitors into leads.

Getting traffic is only step one. The best agencies focus just as much on what happens after someone lands on your page. That means strong headlines, clear messaging, and calls to action that feel natural, not forced.

How to choose an SEO copywriting agency

Proven Track Record

You want an agency that can actually show results, not just talk about them. That means real case studies, traffic growth, lead increases, and happy clients.

At Embarque, for example, we’ve helped Cleanvoice grow its MRR by 300% through focused SEO content. We’ve also driven 9.6 million in annual organic traffic for Flick and helped a technical SaaS product scale traffic by 60×

These kinds of outcomes show that the work doesn’t just look good; it performs.

Industry Knowledge

Your agency should be able to speak your audience’s language. If you’re in SaaS, healthcare, or finance, the team should understand the nuances of your space (or show that they can learn fast).

Some agencies list the industries they specialise in, but it’s also worth asking directly if they’ve worked with companies like yours. Industry relevance means less hand-holding and content that hits the mark faster.

SEO Expertise

This should go without saying, but make sure they actually understand SEO. They should know how to find the right keywords, optimize content, and track performance. Ask how they keep up with algorithm changes or how they handle internal linking. A solid team will be able to explain their process in plain language and show that they’re staying sharp.

How Much Does It Cost to Hire an SEO Copywriting Agency?

SEO copywriting rates can vary a lot depending on what you need, who you’re working with, and how they price their services. Here’s a breakdown of the most common pricing models and what influences the final cost.

Per-Word or Per-Article Pricing

Plenty of agencies charge by the word. Rates usually range from $0.05 to $0.20 per word. For example, a 1,000-word blog post could cost anywhere from $100 to $200, depending on the agency’s experience and what’s included. Some work with flat per-article rates instead. One agency might charge $100 for a short blog, while another quotes $500 for something similar. The difference often comes down to quality, writing experience, and whether they include extras like keyword research, revisions, or visuals.

Monthly Retainers or Packages

If you need content on an ongoing basis, monthly packages are a common option. These can range from $1,000 to $5,000 per mont,h depending on how much content you’re getting and whether services like content strategy or reporting are included. 

Retainers are ideal if you want consistency, and you often get better value compared to one-off projects.

One-Time Project Fees

Some agencies price by project, especially if you have a specific deliverable like a website rewrite or an ebook. A 10-page website rewrite might cost around $2,000. A long-form ebook or white paper could land between $3,000 and $5,000 depending on how technical or research-heavy it is. These fees are usually based on estimated hours, word count, and complexity. 

Hourly rates for writing services typically range from $50 to $150, and most project fees are based on that range multiplied across the work involved.

What Affects the Cost?

  • Experience and quality: The more seasoned the team, the higher the rates. Agencies with a strong track record and expert-level writers will charge more, but they usually need less input and produce stronger content. Less experienced teams or freelancers might charge less, but may also need more back-and-forth.
  • Length and complexity: Longer content naturally costs more. But complexity matters too. Writing a blog about fitness trends is much easier than explaining multi-cloud security in enterprise software. Technical topics or niche industries tend to require more research, which adds to the price.
  • Extra services: If you’re getting strategy, keyword research, uploading, CMS formatting, images, or even content promotion included, expect to pay more. Some agencies bundle this in, others charge separately. Pure writing services are cheaper, but they may leave more work for your in-house teams.
