The [Best] SEO Content Optimization Tool: Platform, Software, & Website

If everything revolved solely around keywords, most SEOs would have found a hack to game the search engine and find a path to riches.

Times have changed – searching just isn’t the same as it used to be 5 years ago, let alone last year. With so many people generating a ton of content every day using AI, Google has made it a priority to filter out the low-quality stuff from its search results. With these changing times and tech advancements, the tools you use to optimize content for SEO also need some upgrading.

We evaluated over 21 tools for SEO content optimization and narrowed it down to the top 8 best SEO tools currently available. This post provides an in-depth look into each one – the good and the bad – along with some key tips along the way. Let’s get started!

What is SEO-optimized content?

Optimized content from an SEO angle is comprehensive, original, engaging, and answers all of the questions users have about a topic. It includes optimized page titles, headlines, HTML tags, meta descriptions, internal links, external links, alt text, and anchor text.

What is an SEO Content Optimization tool or software?

An SEO content optimization tool is a software that helps marketers and content creators improve their content by providing insights and suggestions to tailor their content to better rank on search engines. They use machine learning technology to analyze content and provide suggestions to improve its readability, user intent, and keyword usage.

Marketers trying to gather organic leads or traffic will need an SEO content optimization tool in their arsenal to create an SEO content strategy for predictable content success.

There are many different types of tools for SEO content optimization that can do some or multiple tasks related to optimization. For complete optimization, you are more than likely going to need one or more tools in your arsenal.

SEO Content Optimization Tools Needed for Comprehensive Analysis and Improvement

There are two main types of content optimization tools you will need to make your content the best it can be:

  1. On-page content optimization
  2. Grammar and tone optimization
Types of Tools
On-page Content Optimization1. When creating new content and you want to make sure your content is optimized before publishing2. When optimizing existing content that isn’t ranking well or ranking at all.
Grammar and Tone Optimization1. All content must go through a grammar and plagiarism check before being published or republished.

Key Features to Seek in an SEO Content Optimization Platform

1. Real-time SEO Content Scoring: For Predictable Rankings!

SEO scoring is your secret weapon to outrank competitors. It meticulously examines on-page SEO content elements crucial for ranking. Armed with NLP and keyword density insights, a powerful SEO content optimization tool leaves no stone unturned.

  2. Content (Outlines, NLP terms, Uniqueness, Structure, Depth)
  3. Link structure
  4. Media
  5. Semantic terms

2. Meta Magic: Optimize Titles and Descriptions

A killer title is your golden ticket to SEO success! Choose an SEO content optimization tool that helps craft titles with high CTR potential, the right keywords, and the perfect length. And don’t forget your meta descriptions -while they might not be heavily scored, they still contribute to the ranking factors.

3. Content Structure Mastery: Outlines, Lists, Word Count

Great SEO content checkers not only suggest ideal word count and outlines, but also reveal the secret sauce of competing pages: tables, lists, and stats. Boosting your UX to outshine the rest is a must-have feature for 2023. When everyone is using AI content writing for a quick win, the key to standing out above the rest lies in understanding and improving UX for SEO content.

4. Stand Out with Unique Content

Don’t be a copycat! Google craves fresh, unique content. The right writing checker ensures your content’s originality, setting you apart from the AI-generated masses or constant rewriting of SERP pages. While it’s true that Google seeks comprehensive content, content that does not add any new or unique value won’t rank. Finding the perfect balance of similarity and uniqueness will guarantee predictable SEO content success for your content.

5. Topics & NLP Terms: The Winning Combo

A good SEO content optimization tool will have the best of the best NLP data. It should offer term maps and in-depth topic analysis to keep you ahead of the curve along with mapping keywords with your existing content. Also, look for suggested usage of those NLP terms.

6. Keyword Density: Striking the Perfect Balance

Keyword stuffing is a no-no! Most tools will suggest going after density, which is an old way of optimizing SEO content. Stay away from these tools that suggest how many times a keyword should be used on your page. Instead, focus on fully covering your topic, using keywords that support your content, and defining important terms. A brilliant tool should help you spot any troubling areas when necessary for better ranking.

Avoid keyword stuffing!

7. Media Matters: Images, Videos, Alt Text

Don’t skimp on images, videos, or alt tags!  The right SEO content optimization tool reveals others’ benchmarks, helping you optimize your media to match – or even exceed – the competition. Of course, you don’t want to go overboard with too many images, but that’s where a good SEO content optimization tool comes in handy. It can help you find that equilibrium between visuals and text for search engines and your audience alike.

An image is worth a thousand words, so use it wisely!

8. Link Optimization: All About Connections

Citations and internal links are crucial parts of SEO content. A high-quality optimization tool will suggest anchor text, identify relevant content to link and offer insights on internal and external link numbers. These details can help ensure that your content is not only valuable but easy to navigate.

9. Readability: Keep ‘Em Hooked

No one likes gibberish! Understand your audience and craft content with “perfect readability.” Most SEO writing checkers rely on external tools, but your expertise and know-how make all the difference. A good SEO optimization tool will have integrations with popular tools like Grammarly, CopyScape, Google Docs, and WordPress.

2. Clearscope

Clearscope is an SEO content optimization tool that focuses only on NLP terms optimization and coverage. Clearscope analysis top 10 results and extracts entities using the IBM Watson engine. It’s easy to use but lacks the advanced on-page SEO content optimization features provided by tools like Outranking. Clearscope is more suited for simple workflows.

Pros of Clearscope:

  • NLP terms, frequency, and map: Finds gaps in NLP terms in the content and scores it in real-time.
  • Easy to use: In Clearscope you don’t have to dig through many tabs or clicks because it’s only focused on content optimization for NLP terms.
  • Integration: Clearscope integrates with Google Docs and WordPress.

Cons of Clearscope:

  • Gaps in the practical optimization process for 2023: Much of the optimization has to be done using other tools. The constant back and forth between tools using copy-paste can get a little difficult.
  • Lacks advanced on-page optimization capabilities for the title, structure, semantic terms, and other most important things, unlike Outranking.
  • Doesn’t offer integration with Grammarly and other important tools for comprehensive SEO content optimization.

Pricing:

Clearscope pricing for 10 documents starts at $170 which is quite expensive.

3. Frase

Frase is an SEO content writing tool first and an optimization tool second. Frase uses Google NLP entity extraction to suggest SEO content optimization. It offers some additional features for optimization such as semantic terms for an extra charge. Recently, it added some features for content uniqueness as well. Their core optimization algorithm is heavily dependent on NLP terms usages and keyword density much like Clearscope or SurferSEO. It offers other features related to writing and website insights.

Screenshot of Frase.
Check your phrases with Frase.

Pros of Frase:

  • Offers a lot of features but most of them are not related to SEO content optimization.
  • Does a decent job in collecting NLP terms.
  • It’s beginner-friendly for those on a tight budget and doing most things themself instead of a scaled company or agency environment.

Cons of Frase:

  • Not as comprehensive as Outranking for SEO content optimization. Frase focuses on NLP coverage and density for scoring and optimization.
  • Extremely cluttered UI with many elements floating around. Because it has many small big features, some useful and many not, the UI is packed with buttons and popup panels.
  • Does not offer any SEO features – you must buy an additional $35/month add-on.
  • Limited customer support: If you have any questions or issues with Frase, it may be difficult to get help from their customer support team. Many reviews and G2 say they were barred from the FB group for asking difficult questions.

Pricing:

  • Three pricing plans: Basic, Team, and Enterprise. Starting at $14.99/mo.
  • SEO add-on: $35/month

4. Rank Math – WordPress site content optimization tool

Rank Math is a WordPress plugin that helps in optimizing web pages and posts for search engine results pages (SERPs). It provides users with an extensive framework for all the required and recommended actions they should take whenever they optimize their web blog posts and web pages. The plugin offers an easy-to-follow setup wizard and uses a modular framework with high-performance speed, making it a convenient environment to optimize website posts and pages.

However, compared to Outranking, Rank Math is not as comprehensive for SEO content data and analysis of SERPs. Outranking provides more in-depth data analysis and insights into SERPs, making it a more advanced tool for SEO optimization.

Screenshot of Rank Math's interface.
Though extensive, Rank Math is a limited option as a WordPress plug-in.

Pros of Rank Math:

  • Provides an easy-to-follow setup wizard for users
  • Uses a modular framework with high-performance speed
  • Allows up to 5 focus keywords per post, making it easier to optimize content for multiple keywords

Cons of Rank Math:

  • Not as comprehensive for SEO content data and analysis of SERPs compared to Outranking
  • May not be suitable for advanced SEO optimization needs
  • Some users may find the interface overwhelming or confusing to navigate
  • Only compatible with WordPress only and hence it will only fit into the workflow of folks creating and maintaining their website themselves. It is not a scalable option

Pricing:

  • Rank Math has a free plan as well as two premium plans starting at $59

5. SurferSEO

SurferSEO is one of the most known tools out there for ease of use. Surfer evaluates the SERPs and benchmarks a few more factors compared to Clearscope. Surfer’s scoring for SEO content optimization is based on Outlines, NLP terms coverage, and density and title. While Surfer fits into most workflows, it isn’t as thorough for media optimization, internal links, uniqueness and many other important things that Outranking scores content for.

Screenshot of SurferSEO.
You can see that Surfer still likes to focus on keyword density.

Pros of SurferSEO:

  • Scores for additional elements beyond NLP terms to ensure real word optimization techniques used by pro SEO’s
  • Easy to use and the UI is widely adopted
  • Provides SEO content audit features like Outranking

Cons of SurferSEO:

  • Scoring is based on keyword density, an outdated technique discouraged by Google.
  • Does not follow techniques needed for content optimization in 2023, and is not as comprehensive as Outranking.

Pricing:

SurferSEO starts at $59/month for 10 documents and goes as high as $239/Month.

6. MarketMuse

MarketMuse is AI-powered content research, content brief, and topic optimization tool. It claims to scan hundreds of pages before creating topic models for coverage and density. Though its curated data goes into great depth, it often falls short as the data isn’t very relevant to the main topic. Marketmuse has a standalone feature for optimizing internal links as well.

Screenshot of the Marketmuse interface.
MarketMuse’s focuses on limited NLP terms.

Pros of MarketMuse:

  • Showcases a great deal of topic data
  • More focused on coverage and less on density
  • Their heat map is known for topic coverage visualization

Cons of MarketMuse:

  • Falls short of current optimization practices in 2023
  • Complex workflows will need to pair it with multiple tools for comprehensive optimization
  • Expensive when compared to competitors

Pricing:

  • The free tier of MarketMuse only offers content optimization tools, but for the full package you’ll have to spend $149/month

7. Grammarly – Grammar and Spelling Checker

Grammarly is an online grammar-checking and proofreading tool that spell-checks users and improves conciseness, tone, word choice, and much more – all as you write and suggests improvements. It can be accessed from any web browser and can be used anywhere. It takes just a few minutes to install and then you can use its free basic package for as long as you need.

Screenshot of the Grammarly recommendations in an open document.
Though Grammarly helps with overall language, it falls short of the SEO optimization you need.

Pros of Grammarly:

  • Provides grammar-checking and proofreading suggestions as you go
  • Can improve language and overall tone

Cons of Grammarly:

  • Is a writing checker tool, not an SEO optimization tool and will need to be paired with an on-page SEO content optimization tool
  • Can be distracting: its pop-up suggestions as you are trying to write may detract from overall productivity

Pricing:

  • Free: Basic features like grammar checker and punctuation errors
  • Premium: $12/mo, includes all free features plus word choice, fluency checker, tone adjustments, etc.

8. Hemingway Editor

Hemingway Editor is well-known for being free and easy to use with a simple interface to paste your content in and check for readability issues. This is a great option for people who don’t have Grammarly and can afford to spend some additional time copying and pasting content back and forth between different editors. Can’t expect much from a free tool but Hemingway does a great job for its use case.

This editor covers the basics in a pinch.
