Surfer Homepage

The content editor is particularly useful as Surfer automatically identifies the content that makes the most sense to optimize against overall. When it doesn’t, you can choose for yourself–this is a great feature not commonly found in other content optimization tools.

On top of that, Surfer offers a keyword research tool that enables you to view relevant topic clusters based on your primary keyword. You’ll be able to check search intent for your target audience, evaluate monthly search volume, and view a keyword’s difficulty.

Surfer’s SEO audit tool is also excellent and lets you see where you can improve old content, provides you with a precise list of action items based on what’s working for your target keyword, and you can gain insights on everything from missing backlinks, referring domains, and the structure of your meta tags.

For those that like to dive in and get busy, you couldn’t ask for more.

Advantages and disadvantages

Choose which web content to optimize againstCan be pricey for small projects
Keyword research tool provides valuable insightsNo free trial

#2 – Frase

Frase is best for those that need both content optimization and AI writing functionality in one place.

Frase Homepage

The platform offers a comprehensive and unified content editor that incorporates content optimization, competitor research, and AI writing. On the latter, various AI writing tools are available from within the content editing window, including generating title ideas, blog introductions, and bullet point answers.

Other dedicated AI writing tools, such as the outline generator and paragraph rewriter, are good options for those with limited time. You can also access community-built tools with new ones added regularly.

It’s worth mentioning the topic planner tool that allows you to develop a complete list of long-tail keywords through SERP analysis in a few clicks–it’s still in Beta at the time of writing, but it can give your content marketing a real boost and help you consistently rank on search engines.

I particularly like the ability to create a custom tool on top of Frase’s AI tool, enabling you to focus specifically on the areas that matter the most to you. Originally, Frase had its own AI model that it developed in-house, but it recently switched to GPT-3 (Generative Pre-trained Transformer 3), which has led to improvements.

All in all, there’s a lot to like.

Advantages and disadvantages

Custom tool creation and community built toolsCan lack accuracy in keyword suggestions
Useful outline generatorThe AI assistant isn’t the best
Easy-to-use interface
Video tutorials that explain key features 


Paid plans start at $14.99/month, there are annual discounts available. There is no free plan, however, you can get started with a 5-day trial for $1.

Of particular note is the option to upgrade your content with NLP terms–this is the ability to derive insights from unstructured data using machine learning technology. What it means for you, in other words, is the suggested words and phrases found from your top-ranking competitors in Google, including topic-relevant terms that keep your content ranking and in great shape.

Aside from the text editor itself, Clearscope also provides valuable insights such as the number of times the keyword is searched on Google each month and the competition and CPC; in other words, the competitiveness and cost-per-click in Google for paid advertising campaigns.

The WordPress integration allows you to optimize your content inside the CMS, and you can publish then and there without leaving.
