The 3 Best AI Writers for SEO in 2025 (I Tested Them All)

What is Jasper AI?

I’ll be straight with you—Jasper isn’t cheap. But after burning through $300+ testing mediocre alternatives, I realized why content teams at companies like HubSpot and Shopify use it.

The difference becomes obvious when you’re trying to write about complex topics. I was working on a piece about “enterprise security compliance” for a SaaS client. Most AI tools gave me generic fluff about “keeping data safe.” Jasper understood the nuances—SOC 2 Type II certifications, GDPR compliance frameworks, the difference between encryption at rest vs. in transit.

Here’s what really sold me: the Surfer integration isn’t just keyword stuffing with extra steps. When I input “enterprise security compliance” as my target keyword, Jasper analyzes what the top 20 results are actually covering. It found topics I completely missed—like third-party vendor risk management and incident response protocols.

The content it produced wasn’t perfect, but it was 80% there. More importantly, it covered semantic topics that would take me hours of competitor research to identify. That article now ranks #4 for a keyword with 8,900 monthly searches.

One thing to watch out for: Jasper can get a bit “corporate speak” if you don’t guide it properly. I always add specific instructions like “write like you’re explaining this to a friend, not giving a boardroom presentation.” The results are much more natural.

The Surfer Integration That Changed Everything

This integration is why I stopped testing other AI writers. Here’s exactly how it works in practice:

When I’m targeting a keyword like “email marketing automation,” Jasper pulls data from Surfer SEO that shows me the top 20 ranking pages are covering these specific topics: drip campaigns, behavioral triggers, segmentation strategies, A/B testing, deliverability optimization, and integration capabilities.

But here’s the smart part—it doesn’t just dump these keywords into generic sentences. It understands that someone searching for “email marketing automation” is likely comparing platforms, so it naturally weaves in comparison angles and feature discussions that match search intent.

I tested this against writing the same article manually. The Jasper version covered 23 semantic keywords that I completely missed in my manual research. It also structured the content in a way that directly mirrored what was already working in the SERPs.

The result? Content that feels natural to read but hits all the topical signals that Google expects for comprehensive coverage of the subject.

My Honest Take on Jasper

If you’re the type of person who stares at a blank Google Doc for 30 minutes before writing your first sentence, Jasper will save your sanity. I use it for any article over 1,500 words because it eliminates that initial friction of getting started.

The sweet spot is when you need to produce quality content consistently. I have clients who need 8-12 articles per month. Before Jasper, that meant either hiring expensive writers or spending my entire week writing instead of doing actual SEO strategy work.

Now? I can get a solid first draft in 15 minutes, spend another hour polishing it with my own expertise and examples, and move on to the next piece. The content quality is high enough that it ranks, but personal enough that it doesn’t feel like AI-generated spam.

What is Frase.io?

I discovered Frase while trying to figure out why my client’s “CRM software” article was stuck at position #12 for months. The content was solid, but something was missing.

Frase showed me exactly what that something was. It pulled up the top 20 results and created a content brief that revealed gaps I never would have caught manually. The #1 ranking article covered integration capabilities, pricing models, mobile apps, reporting features, AND customer support options. My article only touched on three of those five areas.

But here’s what really impressed me: Frase didn’t just tell me what topics to cover. It showed me the specific questions people were asking about CRM software—stuff like “Can it integrate with accounting software?” and “How does customer data sync across teams?” These weren’t obvious from keyword research alone.

How I Actually Use Frase (The Real Workflow)

Here’s my exact process: I plug in my target keyword, and within 60 seconds, Frase gives me a content brief that would take me 2-3 hours to create manually.

The Research Phase: Frase analyzes the top 20 results and extracts every topic, subtopic, and related question being covered. It’s like having an assistant read through 50,000+ words of competitor content and summarize what actually matters.

The Content Creation: Once I have the brief, I can either use Frase’s AI writer or take the insights to another tool. The AI writer is decent—not as creative as Jasper, but it understands the context since it created the research brief.

The Optimization Score: This is where Frase really shines. As I write, it gives me a real-time score showing how my content stacks up against competitors. If I’m missing important topics or haven’t covered something in enough depth, the score drops and tells me exactly what to fix.

I used this exact workflow for a “project management tools” article that jumped from position #47 to #8 within six weeks. The difference? My updated article covered 34 relevant topics compared to the original 12.

When Frase Makes the Most Sense

Honestly, Frase is overkill if you’re writing about topics where you already know the competitive landscape inside and out. But for anything competitive or unfamiliar, it’s a lifesaver.

I use it most when I’m entering new niches or targeting keywords where I’m not sure what angle will work. Instead of guessing, I let Frase show me exactly what’s working for the pages that are already ranking.

The $1 trial is legit, by the way. I recommend trying it on one competitive keyword to see if the research insights are worth the monthly cost for your specific situation.

What is AIOSEO?

Look, I know AIOSEO isn’t technically an AI writer. But I’m including it because even the best content in the world won’t rank if your technical SEO is broken.

I learned this lesson the hard way with a client’s blog post about “inventory management systems.” The content was phenomenal—comprehensive, well-researched, answering every question a potential buyer might have. But it sat at position #23 for three months.

The problem wasn’t the content. It was everything happening behind the scenes. The meta description was cutting off mid-sentence. The internal linking was nonexistent. There was no schema markup helping Google understand what the article was actually about. All fixable issues that I just… hadn’t fixed.

AIOSEO caught all of this stuff automatically and gave me a checklist to fix it. That article jumped to position #7 within two weeks of implementing their suggestions.

The Features That Actually Matter

TruSEO Analysis: This gives you a checklist for every post that catches the technical stuff you forget about. Things like: Is your focus keyword in the URL? Is your meta description the right length? Are you using header tags properly? It’s not revolutionary, but it’s thorough and catches mistakes that cost rankings.

Schema Markup: This is huge and most people ignore it completely. AIOSEO automatically adds structured data to your posts, which can get you rich snippets, FAQ boxes, review stars, and other enhanced search results. I’ve seen articles get 40% higher click-through rates just from getting a featured snippet, and schema markup is often what makes that happen.

Internal Linking Assistant: This one surprised me. It automatically suggests internal links as you write, based on your existing content. Internal linking is one of those SEO fundamentals that everyone knows matters but few people do consistently. Having it suggested automatically means I actually do it.

The real value isn’t any single feature—it’s having all the technical optimization happen automatically so you can focus on content strategy instead of remembering to write proper alt text.

Why I Use AIOSEO on Every WordPress Site

The truth is, technical SEO is boring. But it’s also the difference between content that ranks and content that gets ignored. AIOSEO handles the boring stuff automatically so I don’t have to think about it.

Before AIOSEO, I had a mental checklist of 15+ technical items to verify before publishing any article. Now? I write the content, run it through AIOSEO’s analysis, fix whatever it flags (usually takes 2-3 minutes), and hit publish knowing all the technical bases are covered.

If you’re serious about ranking content consistently, you need something like this. The alternative is manually checking every technical detail for every post, and let’s be honest—nobody does that consistently.
