Hailey Friedman

Every day, 15% of the queries that happen on Google are ones that have never been searched before.

That’s why Google updates its algorithm 500+ times per year — to stay current with the way people are living and searching the internet.

So, if you’re an entrepreneur or marketer trying to compete in search engine optimization (SEO), you need a great content optimization tool to keep your content optimized for what searchers—and therefore search engines—are looking for. Frase, MarketMuse, Surfer, and Clearscope are some of the best.

Clearscope, Frase, MarketMuse, and Surfer SEO are all great content and SEO tools, but they’re not necessarily interchangeable. They don’t have all the same features (or price) and depending on the size of your company or whether or not you’re a freelancer, your needs will vary slightly. 

So….which content optimization software is right for you and your business? Keep reading to find out.

What are Content Optimization Tools? 

Content optimization tools are platforms that help modern marketers create relevant and useful content that is fully optimized for what search engines (primarily Google) are looking for. Many content optimization tools use some form of correlational SEO to pinpoint the most important elements of ranking content.

Using AI and machine learning, content optimization software can help you top organic search results by making the optimization process a lot simpler and faster, which helps expedite your content output. 

If you want to have a strong online presence—and especially if your goal is to excel at search engine optimization (SEO) — you need to produce great (optimized) blog posts often.

Content optimization tools can have a variety of functions, including: 

  • Streamlining the brainstorming, writing, and publishing process, including directing any writing staff  
  • Optimizing your content for search engines by providing recommendations for keywords, headings, post length, and more
  • Making more content faster by providing keywords, content briefs and outlines, and AI-written pieces or outlines you can base your writing on
  • Predicting content success by determining ease of ranking for specific keywords and how to change your content to best rank for it (many do this by giving “content scores” as you post)

Overall, content optimization tools can improve your search engine rankings, increase revenue for your business, and help you become an authority in your field.

Sounds pretty good, right?

Now you get to decide whether Clearscope, Frase, MarketMuse, or Surfer SEO is going to be the best content optimization tool for your business!

Clearscope vs Frase.io vs MarketMuse vs Surfer SEO

1. Clearscope 

What Clearscope Says…

“Content drives more traffic with Clearscope. Our AI-powered platform makes it ridiculously easy to get more out of your content.”

About: 

Clearscope is a content optimization tool that uses IBM Watson to analyze the content that search engines rank the highest for specific keywords, and give you suggestions for your content based on this and SEO best practices.

Basically, you tell Clearscope a keyword you want to rank for, say “content optimization tools,” and it reverse-engineers the top results on Google for the term to figure out what words and phrases should be included in your piece to rank well. 

Clearscope will give you a list of key terms and topics as well as competitors who are currently ranking for that term, and a content optimization outline for whichever topic you click “optimize.”

This outline helps you outline the scope of work, decide what topics to cover, and the length of your post, especially because Clearscope suggests a word count length, which is determined by the lengths of top-ranked content for this keyword. 

While you’re working, it assigns a content score based on your post’s word count, readability, and search volume, as well as how to improve this score.

It also audits existing content and gives suggestions for ways to improve it, including content length insights and readability score.

Plus, they have keyword research capabilities like many of the other tools.

Features:

  • Competitor content analysis
  • Content length suggestion 
  • Real-time content assessment and overall grade

What is Content Optimization? 

These days, content needs to be more than just shareable, clickable, and readable. Five hundred words stuffed awkwardly with keywords and headings don’t cut it anymore. 

Optimized content fulfills the user’s search intent by being both informational and relevant to their question—which is exactly what search engines are looking for when ranking pages. Highly optimized blog content is the way we’ve been able to scale this blog into a 6-figure passive income business.

A good content optimization tool will help you adhere to SEO best practices—from word count, title and images, to URLs, tone of voice, and keyword suggestions!

MarketMuse, Frase, Clearscope, and Surfer are super sophisticated and each one does a little bit of everything.

What Does Content Optimization Have to do with SEO? 

Most people don’t realize how easy it is to get started with your own blog, and start growing an audience. 

If you blog two times a week for three months (about 20 posts) about a topic you know very well, you can create a blog audience large enough to engage users, build a community, sell products, and make a profit

But: really good, optimized content is 10x better than average content, so it’s worth the extra effort to make sure it’s optimized for search engines. No one wants to put in a lot of effort to see little or no return. 

Highly-ranked content is no longer about who creates the most of it the quickest, but who creates the highest quality content that’s relevant and helpful to searchers. Just remember: “quality over quantity.”

When people make a search query, Google’s Search algorithms look through their Search index using many factors. Google then organizes and presents the results on the search pages in the most helpful way possible by ranking the pages, and creating the SERP that you hope puts your content on the first page. 

If you can master SEO and make articles rank at will, you’re going to be able to build a repeatable and profitable business. 

But there’s a lot of competition out there: organic search drives more than 50 percent of all website traffic. So in addition to your posts being well-researched, well-written, and relevant—they need to be optimized for search engines. 

What are some of the characteristics of optimized content?

  • It contains the proper keywords
  • It meets a specific content length
  • It uses the right headers, images, disclaimers, etc.
  • It contains links to other credible sources internally and externally

Managing all of these elements becomes a lot simpler when you’re using a content optimization tool. 

Conclusion 

Optimized content will attract consistent traffic to your website, allowing you to see increased conversions and revenue therefore ROI for all of your hard blog-writing work!

Using a content optimization tool can help you expedite your writing output, without sacrificing quality for quantity.
