Semrush vs Marketmuse: Which SEO content tool is right for you?

Picking the right SEO tool can feel overwhelming. There are dozens of options, and they all promise to be the secret sauce for ranking number one on Google. It's a packed market, and two of the biggest names you'll keep bumping into are Semrush and Marketmuse.

They both aim to help you with content, but they approach it from completely different angles. Semrush has grown into a large, modular platform with specialized marketing toolkits for a wide range of tasks. Marketmuse, on the other hand, is a focused AI platform designed to help you build topical authority.

Our goal here is to give you a clear, no-fluff comparison of their features, workflows, and pricing so you can figure out which one is right for you. While these tools are great for planning and optimizing, the landscape of content creation is evolving with the rise of AI-native tools. For instance, platforms like the eesel AI blog writer can take you from a single keyword to a fully published, media-rich article in minutes, handling the execution part of the process.

What is Semrush?

Semrush is one of the giants in the online marketing space. It started as a powerful SEO tool but has since grown into a flexible, modular system of specialized toolkits. It's less a single tool and more of a workshop where you can pick and choose what you need.

It offers distinct toolkits for SEO, Content, AI Visibility, Social Media, and Advertising, which lets you subscribe only to the parts of the platform you'll use. Its main package, Semrush One, bundles the classic SEO tools with their new AI Visibility toolkit, which helps you show up in both traditional search results and AI-powered answers. With over 10 million marketing professionals using it, it’s an industry staple known for its massive dataset and all-in-one capabilities.

What is Marketmuse?

Marketmuse is a content intelligence platform that uses its patented AI technology to help you plan, create, and optimize your content. If Semrush is the all-purpose workshop, Marketmuse is the specialist's studio, built from the ground up for content strategy.

Its entire focus is on helping content teams build topical authority. It does this by analyzing your site’s whole library of content to find gaps, identify opportunities, and show you exactly what to write next to become the go-to expert in your niche. Its standout feature is a metric called "Personalized Difficulty." Instead of just telling you how hard a keyword is to rank for in general, it tells you how hard it will be for your specific site to rank, based on the content you’ve already published.

Feature breakdown: Semrush vs. Marketmuse

Let's get into the details. How do these two platforms actually compare when it comes to the day-to-day work of creating and ranking content?

Core focus and workflow

Semrush is a multi-purpose, modular platform built for marketers who wear a lot of different hats. Its workflow reflects this. You might start in the SEO Toolkit doing keyword research, then jump over to the Content Toolkit to draft an article, and finally check the AI Visibility Toolkit to see if you're being mentioned by large language models. It's a powerful suite, but the content workflow is just one piece of a much larger ecosystem. It’s designed for broad marketing management, not just content creation.

Marketmuse is a content strategy specialist, and its workflow is a straight line built around the content lifecycle: plan, brief, write, and optimize. The whole process is designed to be systematic. It starts by taking a full inventory of your existing content to map out your current topical authority. From there, it helps you build a strategic plan. This makes it a much more streamlined and focused solution for teams whose main job is to create expert-level content.

Keyword research vs. topic modeling

Semrush is highly effective for traditional keyword research. It has a massive database of over 27 billion keywords and gives you all the data points you could ever want: search volume, keyword difficulty, competitor rankings, and more. It's excellent for digging into the data and finding specific long-tail keywords. However, the approach is very much focused on individual keywords rather than the bigger picture.

most seo people still use ahrefs or semrush but the workflow changed. instead of tracking 50 keywords we focus on 8 to 10 that match what buyers actually search for and build content around those. for research some teams add perplexity or chatgpt to find competitor gaps faster, then check everything in search console before doing the work. one agency i worked with went from 6 hour audits to 90 minutes by running screaming frog and a custom gpt that spots duplicate titles and thin pages in one go. if you want cheaper, mangools works fine for local stuff at around $30 a month. the bigger change is using fewer tools and fixing what they show you instead of just making more reports.

Marketmuse takes a different approach with topic modeling and content clusters. It pushes you to think beyond single keywords. The Personalized Difficulty metric is a perfect example of this. Instead of a generic difficulty score, it analyzes your domain's strengths and tells you your actual chances of ranking. Marketmuse helps you understand the entire topic, not just a list of keywords, and advises on how much content you need to create to truly own that topic.

Content creation and optimization tools

Semrush gives you the SEO Writing Assistant (SWA), an add-on that works directly in Google Docs, WordPress, and Microsoft Word. It gives you real-time feedback on things like readability, SEO, originality, and tone of voice. It's suitable for quick optimizations while you write. According to a competitor analysis, its suggestions for semantically related words are limited to 20 words. For more in-depth work, you'd need the full Content Toolkit, which includes an AI Article Generator and a tool for creating SEO briefs.

Marketmuse's core feature is the ability to generate detailed Content Briefs. These aren't just suggestions; they're comprehensive blueprints for your writers. They include recommended subheadings, questions your article needs to answer, and even specific internal and external links to include. Its Optimize application gives you a real-time content score as you write, comparing your draft against a target score and showing you a competitive heatmap of the top 20 ranking pages to easily spot content gaps.

AI-powered writing capabilities

Semrush has integrated AI into its SEO Writing Assistant with features like Rephraser, Compose, and Ask AI. These features operate on a credit system called "Smart Writer Words." The credit system has different costs for different actions. For example, using the AI to expand on a piece of text costs twice as many words as simply rephrasing it. This credit system requires careful management to avoid unexpected costs.

Marketmuse uses its own Marketmuse AI, which combines popular large language models with its own proprietary topic models. The philosophy here is to keep a human in the loop. It's designed to augment a writer's process and help them create expert-level content, not to automate the entire process from a single click. It's about making writers more effective, not replacing them.

there’s a lot of AI “noise” right now. What’s actually working for me are tools that analyze and cluster keywords instead of just spitting them out, and ones that audit existing content for gaps vs competitors. Anything that helps me make better decisions, not just more content. The flashy AI writer tools are mostly hype !! the real wins come from using AI to research smarter, not write faster.

Pricing comparison

This is often where the decision gets made. Let's break down what you can expect to pay for each platform.

Semrush pricing

Semrush recently moved to a modular pricing model based on its different toolkits. This can be great for flexibility, but the costs can add up quickly if you need access to multiple areas of the platform. Their main bundle is Semrush One, which combines the SEO and AI Visibility toolkits.

Here’s the annual pricing for Semrush One:

• Starter: Starts at $165.17/month (billed annually).
• Pro+: Starts at $248.17/month (billed annually).
• Advanced: Starts at $455.67/month (billed annually).

If you want the content creation features, you'll need to add on the Content Toolkit, which is an extra $60/month. This à la carte model gives you control, but it also means the price can climb fast.

Marketmuse pricing

Marketmuse is positioned as a premium, specialized tool, and its pricing reflects that. The company doesn't list prices publicly for its main paid plans, which usually means they focus on custom enterprise deals.

• Free Plan: They offer a generous free plan that includes 1 user and is limited to 10 queries per month. This is perfect for trying out the platform and seeing if its workflow is a good fit for you on a small scale.
• Paid Plans (Optimize, Research, Strategy): These plans unlock the platform's full power, adding site-wide inventory analysis, tracked topics, and a much higher volume of Content Briefs. The jump from the free plan to a paid one is significant, positioning Marketmuse as a tool for teams that are all-in on content strategy.
