How I Used Vibe Coding to Build Custom SEO Tools (Without Writing Code!) – Moz

I’ll admit it: for years, I treated custom SEO tools the way some people treat assembling IKEA furniture without the manualtechnically possible, emotionally questionable. I had ideas for tiny tools that would save me hours every week, but I assumed building them meant one of three things: learning to code properly, bribing a developer with coffee, or buying another subscription I didn’t need.

Then I started experimenting with vibe coding.

If you’ve somehow missed this phrase while busy untangling hreflang tags and explaining to stakeholders why “just rank #1” is not a strategy, vibe coding is the process of describing what you want in plain English and letting AI generate the code, logic, or workflow for you. Instead of writing syntax line by line, you act more like a product manager, QA tester, and slightly dramatic creative director. You tell the AI what the tool should do, what data it should use, what the output should look like, and what counts as success. The AI handles the coding. You handle the judgment.

That shift changed everything for me.

Suddenly, I wasn’t staring at a blank code editor like it had personally offended me. I was building custom SEO tools tailored to my workflow: tools for spotting cannibalization, cleaning exports, generating content briefs, clustering keywords, finding internal link opportunities, and prioritizing fixes. None of them required me to become a full-stack engineer. They required me to think clearly, prompt well, test aggressively, and resist the very human urge to declare “good enough” after the first semi-functional output.

This is the story of how I used vibe coding to build custom SEO tools without writing code, what worked, what broke, and why I think this approach is a big deal for modern search marketers.

What vibe coding actually means for SEO

The phrase sounds casual, but the impact is serious. In SEO, we live in a world of repetitive tasks, awkward exports, disconnected tools, and tiny judgment calls that software rarely handles exactly the way we want. Off-the-shelf platforms are useful, but they’re built for broad use cases. Real SEO work is messy. Your site structure is weird. Your client naming conventions are chaos. Your content team has a spreadsheet system held together by caffeine and hope.

That’s where vibe coding becomes useful. Instead of waiting for a SaaS company to build your dream feature sometime between now and the heat death of the universe, you can create a lightweight tool yourself. You describe the workflow. The AI drafts the code. You test it with your actual data. Then you refine it until it becomes useful.

That doesn’t mean “no thinking required.” Quite the opposite. The real skill is not typing code; it’s defining the problem clearly enough that the machine can build something useful. In other words, vibe coding rewards the same thing great SEO rewards: clarity.

Vibe coding is not the same as blind automation

This part matters. I did not throw random prompts at an LLM and trust whatever came back like it was handed down on a stone tablet. Good vibe coding still needs human review. I checked outputs, ran tests, compared results against known data, and tweaked prompts repeatedly.

Think of it this way: I was not coding, but I was still building. I was defining inputs, logic, formatting rules, exceptions, and success criteria. The AI wrote the code; I wrote the spec. That distinction is why this method works.

Why SEO is perfect for this approach

SEO sits in a sweet spot for AI-assisted tool building. We already work with structured data, repeated workflows, spreadsheets, APIs, rules, and pattern recognition. A lot of what slows us down is not strategic thinking. It’s glue work.

Glue work is the stuff between the “real” tasks: merging exports, cleaning columns, tagging pages by intent, turning Search Console data into something readable, checking title lengths in bulk, or finding which pages slipped in clicks but gained impressions. These aren’t difficult in principle. They’re just annoying at scale.

That makes them perfect candidates for custom SEO automation.

Once I realized I could describe these jobs in plain language and have AI generate the first draft of the solution, I stopped asking, “Can I code this?” and started asking, “Is this workflow worth turning into a tool?” That question is much more useful.

The exact workflow I used to build custom SEO tools

I didn’t begin by asking AI to “build me an SEO app.” That is how you end up with a flashy mess that looks impressive right up until it meets real data and falls over like a folding chair. Instead, I used a simple process.

1. I started with a painfully specific problem

The best tools came from annoyances, not grand visions.

For example:

• “I need to compare branded and non-branded query trends by landing page without doing manual filters every week.”
• “I want a sheet that flags potential keyword cannibalization when two URLs get impressions for the same query cluster.”
• “I need a quick way to suggest internal links for every new article using my existing URL inventory.”

That specificity made the prompt stronger and the tool better.

2. I gave the AI a role, a task, context, and an output format

This was the unlock.

Instead of saying, “Write a tool for SEO,” I’d say something like this:

Role: You are a product-minded Python assistant helping an SEO strategist.
Task: Build a lightweight tool that takes a CSV export from Google Search Console and flags pages with declining clicks but rising impressions over the last 8 weeks.
Context: The CSV includes date, page, query, clicks, impressions, CTR, and position. I want this to run in Google Colab or a browser-based environment.
Output: Return clean Python code, installation notes, column assumptions, and a summary table with recommendations.

That single change dramatically improved results. AI tends to perform better when you define what “done” looks like. Vague prompts create vague tools. Shocking, I know.

3. I chose simple environments

I stayed close to tools marketers already understand: Google Sheets, Google Colab, CSV files, lightweight dashboards, and simple web apps. I wasn’t trying to build the next enterprise platform. I was trying to save two hours on Tuesday.

That mindset helped. A tiny tool that works is worth more than a giant “platform” that never leaves draft mode.

4. I tested with ugly data

Pretty demo data is a liar. Real SEO data has empty cells, weird capitalization, duplicated URLs, trailing slashes, broken encodings, accidental spaces, and naming conventions invented by someone who left the company in 2022.

So I tested every tool using messy exports. If the tool survived that, it was probably useful.

5. I kept the human in the loop

AI can speed up analysis, but it should not be the final authority on SEO decisions. I used my tools to surface patterns and recommendations, then reviewed them before taking action. That kept the work fast and sane.

The custom SEO tools I built with vibe coding

1. A keyword cannibalization spotter

This was one of my favorites because keyword cannibalization is one of those problems people love to discuss and hate to diagnose manually. I prompted AI to create a tool that grouped queries by similarity, mapped them to landing pages, and flagged cases where multiple URLs were competing for the same topic.

Was it perfect? No. Language is messy, and intent overlap is not always cannibalization. But it was good enough to surface likely conflicts fast, which meant I could spend my time making decisions instead of building pivot tables that looked like abstract art.

2. An internal linking assistant

I uploaded a list of existing URLs, target keywords, and page summaries, then asked AI to build a simple matcher that recommended internal links for new articles. The result was not “publish instantly and trust forever” material, but it was incredibly useful as a first pass.

Instead of staring into the void and trying to remember whether we had a good supporting article about title tags, log file analysis, or seasonal search intent, I got a shortlist of likely candidates. I reviewed the suggestions, kept the strong ones, and ignored the weird ones. Productivity: up. Grumbling: down.

3. A title tag and meta description QA checker

This tool was gloriously practical. I asked AI to build something that could scan a CSV of page titles and meta descriptions, flag missing fields, spot duplicates, identify overly long entries, and highlight obvious formatting issues.

Could commercial tools do some of that? Sure. But I wanted custom rules for my workflow. I wanted brand naming exceptions. I wanted priority scores. I wanted quick notes in plain English. Vibe coding let me turn a routine SEO checklist into a tool that matched the way I actually work.

4. A content brief generator

This one felt like cheating in the best possible way.

I used AI to combine keyword clusters, page intent, SERP observations, and internal content gaps into draft briefs. Not final briefs, draft briefs. That distinction matters. The tool helped me move from blank-page paralysis to a structured first version with suggested headings, related entities, content angles, and internal links.

It did not replace editorial judgment. It removed the boring first 40%.

5. A technical issue prioritizer

Not every technical SEO issue deserves the same urgency, but many reports treat them like every missing alt attribute is a five-alarm fire. I asked AI to help build a scoring tool that combined issue type, page type, traffic, indexability impact, and estimated business relevance.

That meant my reports started looking less like “here are 143 things that are wrong” and more like “here are the 12 issues worth fixing first.” Stakeholders loved that. Mostly because it sounded less like chaos and more like a plan.

What made these tools work

The tools were useful because they followed a few simple rules:

• They solved one job well. They were not trying to do everything.
• They used familiar inputs. CSVs, Sheets, and standard exports are easier to manage than fancy custom systems.
• They produced readable outputs. If the result looked like machine soup, I fixed the prompt until it didn’t.
• They were easy to revise. Once the first version existed, improving it was much faster than starting from zero.

That last point is huge. The first version is the hard part. After that, you’re editing. And editing is much easier than inventing.

The mistakes I made so you don’t have to

I asked for too much too soon

My worst early prompts were wildly ambitious. I wanted a dashboard, scoring engine, recommendation model, UI, export system, and probably a parade. The outputs were predictably messy. Once I broke the work into smaller tools, success rates improved fast.

I trusted the first answer

Bad idea. AI-generated code can look polished while still being wrong. I learned to test every assumption: date parsing, URL normalization, duplicate handling, regex logic, edge cases, and output accuracy. Confidence is not the same thing as correctness.

I forgot that data privacy still matters

Just because an AI can process your file doesn’t mean every file belongs in every environment. For sensitive client data, I sanitized exports, minimized unnecessary fields, and used controlled workspaces. Convenience should never outrank judgment.

I tried to automate strategy instead of support it

The best custom SEO tools support expert decisions. They don’t replace them. Whenever I tried to outsource actual strategic thinking to a tool, the result got generic fast. Whenever I used a tool to speed up research, cleanup, formatting, or pattern detection, the results were excellent.

How to get started with vibe coding for SEO

If you want to build your own AI SEO tools without becoming a programmer, here’s the simplest path:

1. Pick one repetitive SEO task that annoys you weekly.
2. Write down the input, output, and rules in plain English.
3. Ask an AI model to build the smallest useful version first.
4. Run it in a familiar environment like Google Sheets or Colab.
5. Test it on messy data.
6. Revise the prompt until the tool behaves the way you need.

Do that once or twice and you’ll stop seeing AI as a chatbot that writes drafts and start seeing it as a practical way to build custom workflows.

My experience using vibe coding to build SEO tools

Here’s the honest version: the first time I tried this, I felt like I was getting away with something.

I had spent years assuming there was a hard wall between “SEO people” and “people who build tools.” On one side of the wall: strategy, content, audits, reporting, and endless spreadsheets. On the other side: code, applications, APIs, and mysterious terminal windows that make everyone in the room look smarter than me. Vibe coding kicked a hole in that wall.

Not by turning me into a developer overnight, but by changing my role in the process.

I stopped thinking, “I can’t build this because I don’t know Python.” I started thinking, “I know exactly what this tool should do, and that might be the more important part.” That mindset shift was enormous. Suddenly my SEO experience became the advantage. I understood the edge cases. I knew what patterns mattered. I knew which outputs were useful and which were just decorative nonsense wearing a dashboard costume.

The process usually looked the same. I’d hit a repetitive task, mutter something unprintable at a spreadsheet, and then open an AI model. I’d describe the problem in plain English, add the columns involved, explain the logic, and ask for a lightweight solution. The first version was rarely perfect. Sometimes it broke on date formats. Sometimes it misunderstood URL variants. Sometimes it confidently invented logic that made absolutely no sense. Very relatable, honestly.

But once the rough version existed, momentum took over. I could fix one issue at a time. “Now handle uppercase URLs.” “Now ignore parameter variations.” “Now export the flagged rows into a separate tab.” “Now add a summary for non-technical stakeholders.” That loop felt less like coding and more like sculpting. I wasn’t creating from scratch; I was shaping.

The most surprising part was emotional, not technical. Building even tiny tools gave me a stronger sense of control over my workflow. Instead of waiting for product updates, filing feature requests, or duct-taping five platforms together, I could create something tailored to the exact problem in front of me. Some of the tools were tiny. One just cleaned page titles and highlighted likely duplicates. Another simply grouped queries into rough topic buckets. None of them were revolutionary. All of them were useful.

And that’s the point. Vibe coding didn’t turn me into an engineer. It turned me into a better builder. For SEO professionals, that’s a very big deal.

Conclusion

Vibe coding won’t replace technical teams, and it won’t magically solve bad strategy. What it will do is make custom SEO tool creation dramatically more accessible for marketers who understand the work but don’t speak fluent JavaScript before coffee.

That’s why I think this shift matters.

For years, the gap between “I wish this tool existed” and “here is the tool” was too wide for most SEOs to cross. Now it’s much narrower. If you can define a workflow, explain a problem, test an output, and refine instructions, you can build things that used to feel out of reach.

So no, I didn’t become a coder. I became something more useful for modern search: an SEO who can turn ideas into working tools.

And frankly, that feels like a much better use of the vibes.
