The step-by-step AI workflow that takes you from "I have no idea what to write about" to a published, optimised blog post. No paid tools required.
You've been told you need to "do keyword research." So you look at Ahrefs. It's $99/month. SEMrush is $139. Ubersuggest wants $29 just to show you numbers that may or may not mean anything.
Then you spend three hours staring at a spreadsheet full of search volumes, keyword difficulty scores and competition metrics. You end up more confused than when you started. Nothing gets written. Nothing gets published.
There's a better way. An AI keyword research workflow that uses only free tools, runs in 90 minutes, and ends with a finished blog post ready to rank. Here's the whole system.
Traditional keyword research was built for SEO agencies with six-person teams and enterprise budgets. The tools are powerful. They're also massive overkill for a solopreneur trying to publish one blog post a week.
Here's what usually happens:
The real goal of keyword research is simple. Find what people are searching for. Check whether you can realistically rank for it. Then write something useful. That's it. Three steps. You don't need a $139/month tool for three steps.
Here's the full workflow, broken down by time. Six steps, 90 minutes total, zero paid tools.
Each step feeds the next. The output from step 1 becomes the input for step 2. By the end, you've gone from "I have no idea what to write" to a published, optimised post. That's what a complete 90-minute AI SEO workflow looks like in practice.
Let's walk through each step.
You need a starting point. Not the perfect keyword. Just a starting point. Here are three free sources that give you real data in minutes.
You can access this for free with a Google Ads account. You don't need to run ads. Just create an account, open Keyword Planner, and type in a broad topic related to your business.
If you're a fitness coach, start with "home workout plan." If you're a freelance designer, try "small business branding." Keyword Planner will return dozens of related terms with monthly search volume ranges and competition levels.
You're looking for keywords with decent volume (100–1,000 monthly searches is plenty for most solopreneurs) and low or medium competition. That's the sweet spot.
Open Google. Start typing your topic. Don't hit enter yet. Watch what Google suggests. Those suggestions are real searches that real people are making right now.
Now hit enter. Scroll down to "People also ask." These are question-based keywords that Google is already associating with your topic. Copy 5–10 of them into a doc. These are gold for blog post ideas and FAQ sections.
Open ChatGPT and give it this prompt: "I'm a [your role] who helps [your audience] with [your topic]. Brainstorm 20 specific things they might search for on Google related to [your seed keyword]. Focus on practical, how-to searches."
ChatGPT won't give you search volume data. But it will give you angles and variations you wouldn't have thought of. Combine its suggestions with the Keyword Planner data, and you've got a shortlist in 15 minutes.
The golden ratio: look for keywords where the search volume is decent but the top-ranking pages are thin, outdated or written by generalists. That's where you win.
You've picked your keyword. Before you write a single word, Google it. Seriously. Open an incognito window and search for your exact keyword. Look at what's ranking on page one.
Ask yourself three questions:
Match your content type to the intent. If people searching "free keyword research workflow" are looking for a step-by-step tutorial, write a step-by-step tutorial. Don't write an opinion piece. Don't write a product review. Give them what they came for.
This step takes 10 minutes and saves you from writing the wrong thing entirely.
Now you build the skeleton. Open ChatGPT and give it context:
"I'm writing a blog post targeting the keyword [your keyword]. Here's what's currently ranking on Google: [paste the titles and key points from the top 3–5 results]. Write an outline that covers everything these posts cover, plus adds [your unique angle]. Include 3–4 FAQ questions at the end."
Two things matter here. First, you're not asking AI to guess what to write about. You're feeding it real competitive data. Second, you're adding your angle. Maybe it's your specific experience. Maybe it's a simpler approach. Maybe it's a contrarian take. Whatever makes your version different from the ten posts already ranking.
The FAQ questions are strategic. Google pulls FAQ content into featured snippets. Four good FAQ items at the bottom of your post give you a shot at position zero without any extra work. If you want to see how this fits into a broader content system, the content in 2 hours workflow uses the same outlining approach.
Spend 5 minutes reviewing the outline. Rearrange sections. Cut anything that doesn't serve the reader. Add any points you know from experience that AI missed. Then move on.
This is the longest step. It's also where most people go wrong. They paste the outline into ChatGPT and say "write the blog post." Then they get 2,000 words of generic, robotic filler.
Don't do that. Use a prompt chain instead.
This takes longer than a single prompt. It also produces something 10x better. Each section gets your attention. Each section gets specific input. The result sounds like a real person wrote it, not a language model filling space.
AI drafts need editing. Not heavy rewriting. Editing. Read each paragraph and ask: would I actually say this? If the answer is no, rewrite that sentence in your own words. Cut the filler phrases. Remove the "in conclusion" and "it's important to note that" padding. Make it sound like you.
If you're building a full AI marketing stack on a budget, this drafting workflow is the core of your content production. Same process, every post, every week.
Your post is drafted. Now make sure Google can read it properly. This takes 10 minutes and most of it is just filling in boxes.
Include your primary keyword. Keep it under 60 characters. Make it specific and clickable. "AI Keyword Research in 90 Minutes (Free Tools Only)" is better than "How to Do Keyword Research."
155 characters max. Include the keyword. Tell the reader exactly what they'll get. This is an ad for your post in search results. Write it like one.
Your H1 is the post title. Each major section is an H2. Subsections are H3s. Include keyword variations in your H2s naturally. Don't stuff them. Google is smarter than that.
Link to at least 3 other pages on your site. This helps Google understand your site structure and keeps readers moving through your content. Every blog post should point to related posts and at least one product or resource page.
Every image gets descriptive alt text. If you have a screenshot of Google Keyword Planner, the alt text is "Google Keyword Planner showing search volume data for AI keyword research." Describe what's in the image. Include the keyword where it fits naturally.
Short, descriptive, keyword-included. /blog/ai-keyword-research-workflow beats /blog/2026/03/01/my-keyword-research-post-v2-final every time.
For the full SEO checklist and how it fits into a repeatable system, the keyword research in 90 minutes workflow covers everything from keyword research through to tracking results.

Take the Free QuizYou've got a draft. You've done the SEO. Now make it good.
Read your post out loud. Every sentence. If you stumble, the sentence is too long or too awkward. Rewrite it. If you get bored, cut that section. If something sounds like a textbook, make it sound like a conversation.
AI loves filler. Phrases like "it's worth noting that" and "as we discussed earlier" and "in order to effectively." Delete all of it. Aim for 1,500–2,000 words of substance. Not 5,000 words of padding. Shorter posts that say something beat longer posts that don't.
Every post needs a next step for the reader. Link to a related product. Invite them to take a quiz. Offer a free resource. Don't just end the post. Give them somewhere to go.
Seriously. Don't sit on it. Don't "polish it one more time." Publishing a good post today beats publishing a perfect post never. You can always update it later when you see how it performs in Search Console.
