Top 10 SEO Experts in the World: A Complete Guide to the Best in the Industry
What Are AI SEO Writing Tools?
AI SEO writing tools are software powered by artificial intelligence (often using advanced language models) that assist in generating and optimizing written content for search engines. Unlike generic AI text generators, these tools have features geared toward SEO (Search Engine Optimization) – such as keyword suggestions, content scoring, competitor analysis, and optimization tips.
They help writers produce content that is not only well-written but also rich in relevant keywords and structured to rank higher on search engine results pages (SERPs). In short, an AI SEO writing assistant can save time by generating draft content and providing SEO guidance, while you maintain control over quality and accuracy.
Google’s own stance is that AI can be a helpful part of content creation if used responsibly. You should avoid simply publishing AI output without review; instead, use these tools to streamline research, drafting, and optimization while ensuring the final content is original, accurate, and written for humans.

2. Jasper AI – The Content Creation Wizard
Jasper AI (formerly known as Jarvis) is one of the most popular AI writing tools, widely used for generating blog content, marketing copy, and more.
While Jasper is a general AI writer, it offers SEO-specific templates and even integrates with Surfer SEO for content optimization
Jasper excels at turning simple prompts into well-structured articles, and it supports multiple tones and languages, making it a versatile content creation powerhouse.

Jasper also includes a “Jasper Chat” mode for conversational prompting and a Chrome extension for writing assistance across the web.

Writesonic is an AI writing platform known for its affordability and ease of use. It offers a wide range of content templates (over 80, including a Blog Article Writer) and keeps SEO in focus by providing features like keyword suggestions and SEO optimization modes. For bloggers on a budget, Writesonic can produce everything from full blog posts to social media captions, with a user-friendly interface and multi-language support
- Key Features: Pre-built templates for blog posts, articles, product descriptions, ads, and more (including an AI Article Writer that can generate an SEO-friendly blog post from an outline). It has a simple editor with built-in SEO checks and also supports content rephrasing and multi-language generation.
- Pros: Very affordable compared to many competitors, making advanced AI writing accessible to individuals and small businesses. It’s praised for a simple, intuitive interface that’s easy for beginners. Writesonic generates content quickly, and the quality is solid for general topics – giving users a “first draft” that often needs only minor editing. It also offers a free trial and even a limited free plan, so you can test it out with no commitment.
- Cons: Writesonic’s SEO features, while useful, are not as in-depth as specialized SEO tools – you might not get the same level of optimization guidance as Surfer or Frase. Integrations are somewhat limited (it’s largely a standalone web app). Occasionally, longer articles may require fact-checking or additional tweaking to ensure they meet expert-level quality.
- Pricing: Freemium. Writesonic has a free trial and even a free tier (with limited credits). Paid plans start around $19/month (for ~100K words with GPT-3.5), and an “Unlimited” plan is available (approximately $16–$19/month if billed annually). This makes it one of the more cost-effective AI writers.

| Focus on Optimization | Allows you to refine and optimize the content, which AI may not handle entirely. |
4. Frase.io – The AI Content Research and Optimization Powerhouse
Frase is an AI-powered tool that goes beyond writing – it’s an all-in-one platform for content research, brief creation, writing, and optimization.
Frase analyzes top search results for your target query and helps you identify the key topics, questions, and headers to cover in your article
It then uses its AI writer to help produce the content. Essentially, Frase can build a content brief and draft in minutes, ensuring your blog post covers the same ground as the highest-ranking pages (and hopefully offers something more).
- Key Features: SERP analysis (Frase will show you what the top 20 results are covering), content brief generator, an AI writer that can continue your sentences or write paragraphs, and an SEO content editor that scores your content for topic coverage. It also includes a questions research tool (great for finding FAQs people ask) and supports content outline creation.
- Pros: Excellent for research and content planning – Frase ensures you include all relevant subtopics and keywords that competitors have, which is key for SEO. The tool is a powerhouse for creating comprehensive, optimized content briefs in a short time. It’s especially useful for long-form content and content marketers who want data-driven guidance on what to write. Users love that Frase can drastically cut down the time spent on researching what to include in an article. It’s like having an SEO content outline handed to you, which you can then fill in with the help of AI.
- Cons: The depth of Frase’s features can be overwhelming for beginners. New users might find the interface busy – with so much data (keywords, topic scores, etc.), there’s a learning curve to using Frase effectively. Additionally, Frase’s AI writing, while good, isn’t a full substitute for a human writer’s insight – you’ll still need to refine and fact-check. Pricing is mid-range, and the free version is very limited (mostly a brief trial), so it’s an investment.
- Pricing: Premium (no free plan, but free trial). Frase offers a 5-day trial for $1 (as a test period). Regular plans include Solo (around $15/month for individuals, limited usage), Basic ($45/month for moderate use), and Team ($115/month for heavy use or multiple users). (These plans often have limits on how many content briefs or AI-words you can generate.)
5. Copy.ai – The Quick and Creative Content Generator
Copy.ai is a well-known AI writing tool geared towards generating all sorts of marketing copy and blog content with minimal input.
While it doesn’t have deep built-in SEO analytics like Surfer or Frase, it’s often used to produce initial drafts of blog sections, introductions, or social media captions that can then be optimized for SEO.
Copy.ai’s strength lies in its simplicity and creativity – it can take a short prompt and produce multiple variations of engaging text.
- Key Features: A wide array of templates for blogging (blog ideas, blog intros, outlines, and full blog posts), as well as for digital copy (product descriptions, emails, ads, etc.). It supports over 25 languages and offers tone options. The interface is straightforward: you provide a prompt or some context, choose a tool (e.g., “Blog Section”), and Copy.ai generates several results to choose from.
- Pros: Fast and user-friendly – great for quickly whipping up content for various needs. Copy.ai often produces lively and human-like copy; many users find its outputs require less editing for tone. It’s excellent for brainstorming, as it can generate content ideas or different angles on a topic. Multi-language support is a plus for those targeting international audiences. The learning curve is virtually zero – you can start generating content within minutes of signing up.
- Cons: Copy.ai is not specifically SEO-focused, so it won’t give you keyword density or competitor analysis. Content generated may need further SEO tuning (e.g., adding specific keywords or structuring into an optimized format). It also may produce somewhat generic text if the prompt is vague, so giving it detailed input yields better results. Essentially, it’s a great writing assistant but lacks advanced SEO features, which means you’ll likely use it alongside an SEO tool for best results.
- Pricing: Freemium. Copy.ai offers a Free plan that allows up to ~2,000 words per month – good for trying it out. The Pro plan is around $49/month (with unlimited words and additional features). Often, they run discounts for annual subscriptions. As a freemium model, it’s accessible to start, with the paid plan unlocking its full potential.
6. Article Forge – The AI-Powered Long-Form Content Generator
Article Forge is an AI tool that takes a slightly different approach: it aims for full automation of long-form content creation. You enter a keyword or a short prompt, and Article Forge will generate a complete article for you – including introduction, body, and conclusion, and even adding titles or section headings. It markets itself as providing “SEO content on autopilot”
which is attractive for those who need bulk content. The tool uses deep learning to write about virtually any topic, and it tries to include relevant keywords and even related media (images, videos) in the output.
- Key Features: Completely automated article generation (you can specify length, keyword, and some optional sub-keywords or headings), integration to add images or videos automatically, and the ability to generate multiple articles in bulk. It also has an API for integration into other systems. Article Forge emphasizes that its content is unique and passes plagiarism checks, making it suitable for SEO purposes.
- Pros: Extremely convenient for generating a quick article draft – literally one click to a full article. It’s useful if you have to produce a lot of content (e.g., for supporting blog posts, PBNs, or content farms) with minimal effort. The content is generated with basic SEO in mind, often incorporating the target keyword and related terms sufficiently. There’s a 5-day free trial and affordable base pricing for a decent volume of words, which is appealing for budget-conscious users.
- Cons: Fully automated content can be hit-or-miss in quality. While Article Forge has improved over time, the articles may still feel somewhat generic or shallow in insight (since the AI can’t provide deep expertise or updated information in niche areas). Users often find they need to edit the output for clarity and accuracy. It’s best used as a starting point – you shouldn’t publish directly without reviewing. Also, the level of SEO optimization is basic; it ensures keywords are present, but it’s not on the level of Surfer/Frase in terms of competitive analysis. In short, convenience comes at the cost of requiring careful human oversight to ensure quality.
- Pricing: Premium (with trial). Article Forge’s pricing is based on word count. Plans start around $27/month (for up to 25k words) if billed monthly. There are discounts for annual plans (as low as ~$13/month for the same tier, with 51% off). Higher tiers allow more words or users, and there’s a custom Enterprise option. All plans come with the 5-day free trial (which actually lets you generate articles, so you can evaluate quality).
7. ContentBot – The Versatile Content Creator
ContentBot is an AI writing tool designed for versatility – it can generate everything from long-form blog posts to short marketing copy, emails, and even ideas.
It comes with multiple AI engines and offers workflows for content creation. In the context of SEO, ContentBot provides an “SEO Assistant” mode where it gives some optimization tips as you write.
It may not be as famous as Jasper or Copy.ai, but it has a loyal user base and is appreciated for continuous feature updates.
- Key Features: Blog post generator, content rewriter, idea generator, as well as tools for email copy and ad copy. It also supports a continuous writing mode (where it keeps generating content as you guide it) and offers integrations like a WordPress plugin. The SEO content optimization feature highlights keywords and gives basic SEO scores for content. Multi-language support is included as well.
- Pros: Highly versatile – suitable for bloggers who wear many hats and need an AI helper for various content formats (not just blog posts). It’s praised for giving useful SEO tips during writing (for example, suggesting internal links or keyword usage) without needing a separate tool.ContentBot tends to be more affordable, offering both subscription and pay-as-you-go options, which is great for occasional users. It’s also relatively young and rapidly improving, with new features being added (like better integrations and templates).
- Cons: Compared to specialized SEO content tools, ContentBot’s SEO guidance is not very deep – consider it a light assist. It might not catch advanced optimization opportunities. Some users find that while it’s good at many types of content, it’s not best-in-class at any single one; for example, its long-form writing can still require edits and its interface can feel a bit utilitarian. It also lacks direct integration with research data (like Frase provides), so you might need to pair it with manual research. Overall, it may not replace your dedicated SEO tool, but complements it.
- Pricing: Freemium options. ContentBot offers a unique “pay as you go” credit system (e.g., $1 for a certain number of words), as well as subscriptions. Subscription plans start around $19/month (Starter) and go up to $59/month (Premium) for higher word limits and features. There isn’t a totally free plan beyond some initial credits, but the low-cost starter options make it accessible.
8. INK Editor – The SEO-First Writing Assistant
INK (often called INK Editor or INKforall) is an AI writing tool built with an “SEO-first” approach. It combines AI co-writing with an SEO optimization assistant that gives you a content score (similar to Surfer or Clearscope) as you write.
INK’s philosophy is to help you write content that is highly optimized from the get-go, rather than having to optimize after writing. For anyone who wants to ensure their blog post is crafted with SEO in mind at every step, INK is a powerful ally.
- Key Features: Real-time SEO analysis and content scoring – as you write in INK’s editor, it scores your content and gives suggestions to improve SEO (like adding certain keywords or adjusting readability). It also offers AI text generation to help you write paragraphs or rewrite sentences. INK includes an outline generator, a headline optimizer, and even an AI image generator. It supports multiple content formats and has a distraction-free editor.
- Pros: Excellent SEO recommendations while writing – you get immediate feedback if your content might not be fully optimized. INK’s content score and suggestions stem from an analysis of top-ranking content, so it’s like having an SEO expert guiding your writing. It’s perfect for those who want to make sure they have the right keyword density, adequate length, and semantic keywords naturally included. INK supports various content types (blog posts, social media, etc.) and keeps the focus on optimization across all. The interface is feature-rich, and for folks who love data, INK provides plenty of insights. It also has a free tier (with limited usage) which is nice for trying it out.
- Cons: Many advanced features (like higher monthly word counts or some SEO recommendations) are locked behind the premium plan.The interface can feel a bit cluttered or complex for new users who just want to write – there’s a lot on the screen (scores, tips, side panels). INK’s AI writing capability is good but sometimes not as naturally fluent as Jasper or Copy.ai when creating content from scratch; its strength is really in guiding SEO. Additionally, the cost for the full version is on the higher side (though it can replace both a writing tool and an SEO tool, which might justify it).
- Pricing: Freemium. INK offers a Free plan (with limited credits, e.g., a certain number of AI words and SEO analysis per month). The Pro plan is around $35–$39/month which unlocks unlimited AI writing and full SEO features. There’s also an Enterprise tier for team collaboration. The free version is useful for light use, but serious bloggers aiming to use INK regularly for SEO content will need the paid plan.
9. Anyword – The AI Copywriter with SEO and Conversion Focus
Anyword is an AI writing platform originally known for marketing copy (ads, social posts, landing pages), but it’s also quite capable for blog content – especially if you want your posts to be SEO-friendly and conversion-oriented.
Anyword’s unique angle is its predictive performance score for copy: it can predict how engaging a piece of text might be and even suggest improvements to increase conversions (like click-throughs or sign-ups).
For bloggers who also have an eye on conversion (e.g., CTAs in the post, or making content that leads to action) in addition to SEO, Anyword is a great tool.
- Key Features: AI content generation for multiple use cases – from full blog posts to ad headlines. It allows customization of tone and style, and importantly, it has a mode to optimize for certain outcomes or demographics (useful in marketing). Anyword also offers an SEO keyword bank where you can input target keywords, and it will ensure the generated content includes them appropriately. Its predictive analytics will score your copy for effectiveness. Multi-language support is included.
- Pros: Great for writing content that is both SEO-friendly and persuasive. It’s like having a copywriter and an SEO assistant in one. For example, Anyword can generate a blog section and also tell you a predicted engagement score for that section, suggesting which variant might keep readers hooked longer. It’s flexible in tone – you can indicate if you want the text more casual, professional, witty, etc., and Anyword adapts. The interface is straightforward, and they provide a lot of templates for different needs. Many users find Anyword’s output to require minimal editing, and they appreciate data-driven features (like seeing which version of a title might perform better).
- Cons: Anyword’s focus has been more on marketing copy, so its long-form blog writing, while strong, is slightly less specialized than a tool like Jasper for creative storytelling or Frase for pure SEO research. The long-form assistant may need guidance via outlines to get the best results. It’s also one of the pricier tools if you want the full suite (including predictive scoring). Additionally, if you’re only focusing on SEO and not on conversion, you might not use all of Anyword’s unique features – meaning a portion of what you pay for could be underutilized if you just need basic AI writing.
- Pricing: Premium (with free trial). Anyword doesn’t have a perpetual free tier, but it offers a 7-day free trial. Paid plans start at around $49/month (Starter) which includes core features and a decent word limit The Business plan (for higher volume and advanced features) jumps to about $99/month or more. They also have higher enterprise tiers. Essentially, it’s an investment, but it packs a lot into one platform (AI writing + predictive analytics).
10. Rytr – The Affordable AI Content Assistant for Beginners
Rytr is an AI writing assistant known for being budget-friendly and user-friendly. It’s a great choice for bloggers or small business owners who need help creating content but don’t want to spend a lot.
Despite its lower price, Rytr offers a solid set of features for generating short and long-form content, including blog articles. It also has an SEO mode where you can input keywords and Rytr will attempt to incorporate them and optimize the text.
For those just starting out with AI writing tools and SEO content, Rytr provides an excellent balance of functionality and cost.
- Key Features: Supports writing in 30+ use cases (blog ideas, outlines, paragraphs, product descriptions, etc.) and 20+ tones. It allows you to choose the creativity level of the output (e.g., factual vs. more creative). Rytr can generate full article drafts if guided with an outline. It also offers a built-in plagiarism checker to ensure content originality. For SEO, you can specify keywords to include, and it has a keyword suggestion feature as you write.
- Pros: Very affordable – one of the cheapest AI writing tools with useful capabilities. It even has a free plan, and the unlimited plan at $29/month is a standout value for unlimited content generation. Rytr’s interface is simple and not overwhelming, which is perfect for users who want results without fiddling with too many settings. It supports multiple languages, and the quality of output is generally good for general topics. It’s especially handy for quickly drafting sections of an article or social media content. In a nutshell, Rytr covers the basics well without breaking the bank.
- Cons: Rytr is not as feature-rich as some higher-end tools. Its SEO suggestions are relatively basic – you won’t get the deep analysis of a Surfer or the robust research of a Frase. It may sometimes produce shorter outputs than desired (you often generate content in smaller chunks and then ask for continuations). For very technical or complex topics, its output might lack depth. Essentially, it’s great for straightforward content, but for advanced SEO strategy or very nuanced writing, you might outgrow it. However, many users pair Rytr with other free SEO tools (like Google Keyword Planner or Yoast guidelines) to cover any gaps.
- Pricing: Freemium. Rytr offers a Free plan (which allows up to ~5,000 characters per month). The Saver plan is about $9/month for 50,000 characters (and lets you generate slightly longer pieces than the free tier). The Unlimited plan is $29/month for unlimited characters – a very competitive price point for unrestricted use. This tier is popular among power users due to its cost-effectiveness.
