Test AI Writing Tools for SEO Free: A 7-Point Score Sheet
Quick answer: Use each tool's free plan or trial with the same real keyword and the exact same prompt. Save each draft, ask for one fixed revision, time your editing, and score accuracy, search intent, originality and readability. Pay only for the tool that wins on a topic you know well.↗ Share on X
You can test AI writing tools for SEO content without paying anything by running the same small test on each tool's free plan or free trial: one real keyword, one identical prompt, one draft per tool, then a side-by-side score on accuracy, search intent, originality, and how much editing the draft needs. Do not sign up for anything that asks for a card "just to start," and do not judge a tool by its demo page. Judge it by the draft it gives you for a topic you know well.
Below is the exact test, step by step, with a scoring sheet you can copy.

Writing Blog Posts With AI: When It Pays Off (and When Not) →Set this up once. It takes about 20 minutes and makes every test fair.
1. Pick one real keyword from your own site. Choose a topic you know well enough to spot mistakes. Example for a local business site: "how often to service a home AC unit."
2. Look at the current top results for that keyword. Open the first five results in Google. Write down what they all cover: the main questions, the format (list, step-by-step, comparison), and the rough length.
3. Write one prompt and never change it. Every tool gets the same words. If you tweak the prompt for one tool, the comparison stops being fair.
4. Create a free email just for testing. Trials send a lot of follow-up email. Keep your main inbox clean.
5. Open a simple spreadsheet with the scoring columns shown later in this article.
A test prompt you can reuse
Copy this and fill in the brackets:
Write a blog post for the keyword "[keyword]". The reader is [who they are]. Answer the main question in the first paragraph. Use short sentences and plain words. Include a numbered list of steps and one table. Use question-style subheadings. Do not invent statistics, studies, or expert names. Length: about 1,200 words.
The last instruction matters. It shows you which tools follow directions and which ones make things up anyway.

Where can you get free access without a card?
Free access changes often, so check each tool's pricing page on the day you test. In general you will find three kinds of free access:
| Type of free access | What you usually get | What to watch for |
|---|---|---|
| Free general chat assistants | A chat window with daily or hourly limits | Limits reset; long posts may get cut off |
| Free plan of a writing tool | A small monthly word or credit allowance | Some features (like SEO scoring) locked |
| Free trial of a paid tool | Full features for a short period | Often asks for a card; set a reminder to cancel |
Rule of thumb: if a trial asks for a card, write the end date in your calendar the moment you sign up. Better yet, skip those until you have narrowed your list to two finalists.

9 Signs You Are Using The Best Free AI Writing Tool Wrong →Do this for each tool. Keep everything the same except the tool.
1. Paste the exact prompt. No follow-up instructions on the first try.
2. Save the raw draft in a document, named with the tool and the date.
3. Ask for one revision with this fixed follow-up: "Make the first paragraph answer the question directly and remove any claim you cannot support." Save that version too.
4. Time yourself editing the revised draft until you would be comfortable publishing it. Write down the minutes.
5. Score it using the sheet below.
Test at least three tools. Five is better. Fewer than three and you have nothing to compare.
What should you score, and how?
Give each item a score from 1 (bad) to 5 (great). Total them at the end.
| What to check | How to check it | Score 1-5 |
|---|---|---|
| Factual accuracy | Mark every claim you know is wrong or can't verify | |
| Answers the question fast | Is the answer in the first paragraph? | |
| Matches search intent | Does it cover what the top five results cover? | |
| Adds something new | Is there a tip, example, or angle the top results lack? | |
| Follows instructions | Table, numbered list, no invented numbers? | |
| Reads like a person | Short sentences, no filler, no repeated phrases | |
| Editing time | 5 = under 15 min, 1 = over an hour |
The three checks that matter most
- Invented facts. Search for every number, date, study, and name in the draft. If you find even one made-up statistic, lower the accuracy score hard. Publishing false claims hurts trust with readers and with search engines.
- Generic filler. Look for sentences that could appear on any website: "In today's fast-paced world," "It's important to note," "In conclusion." Count them. More than a handful means heavy editing.
- Missing experience. The top results often include real details: a price range, a time estimate, a common mistake. If the AI draft has none, you will need to add them yourself. That is not a flaw you can fix with a better tool; it is the part only you can bring.
Is AI writing detectable by Google, and does it matter?
Google has said publicly that it cares about whether content is helpful, not whether a person or a machine typed it. What gets pages pushed down is content made mainly to rank, with no real value for the reader. So the question to ask is not "will Google detect this?" but "is this page better than what already ranks?"
AI detector tools you find online are not reliable enough to base decisions on. Do not waste your test time running drafts through them. Spend that time on fact-checking and adding your own examples instead.
How do you make an AI draft sound human?
These edits work with any tool and take about 15 minutes per post:
1. Rewrite the first paragraph yourself. Answer the question in your own words. This is the part readers and search snippets see first.
2. Add one real example from your work, your customers, or your own experience.
3. Cut every sentence that says nothing. If you delete it and the paragraph still makes sense, it did not belong.
4. Replace vague words with specifics. "Regularly" becomes "once a year, before summer." "Affordable" becomes a real price range you know.
5. Read it out loud. Anywhere you run out of breath or stumble, break the sentence in two.
The tool that needs the fewest of these fixes for your topic is the best tool for you, no matter what review sites say.
How do you pick a winner?
Add up the scores. Then look at three things together:
- Highest total score tells you which draft was best overall.
- Lowest editing time tells you which tool saves you the most work.
- Accuracy score is a veto. A tool with a great total but a low accuracy score is risky, because you might miss an error one day.
If two tools are close, run a second round with a different keyword, ideally a harder one. A tool that does well on two different topics is a safer bet than one that won a single round.
Only after this do you consider paying. And even then, pay month to month first. Commit to a yearly plan only when you have used the tool for real work, on real deadlines, for at least a couple of months.
Common mistakes when testing AI writers
- Testing with a topic you don't know. You can't spot errors, so every tool looks good.
- Changing the prompt between tools. The result then measures your prompt, not the tool.
- Judging the first draft only. Most tools improve a lot after one clear revision request. Test the revision too.
- Counting words instead of quality. A longer draft is not a better draft. It is usually more editing.
- Forgetting to cancel a trial. Put the end date in your calendar the same day.
Your next step
Today, pick one keyword from your site that you know well and write your test prompt using the template above. Then run it on the free chat assistant you already use. That first draft, scored with the sheet in this article, becomes your baseline. Every other tool you test from now on has to beat it, or it is not worth your money.
FAQ
How many AI writing tools should I test?
At least three, ideally five. With fewer than three you have nothing meaningful to compare, and with more than five the testing starts taking longer than the writing.
Does Google penalize AI-written content?
Google has said it focuses on whether content is helpful, not on who or what wrote it. Pages made mainly to rank with little value for readers are the ones that lose visibility.
Should I use an AI detector to check my drafts?
No. Online detectors are not reliable enough to base decisions on. Spend that time checking facts and adding your own examples instead.
