I use AI in SEO for the first, messy part of the job: sorting notes, finding gaps in an outline and getting a draft moving. Then I do the part the tool cannot do for me. I decide what the page should say, check the facts and make sure it helps the person reading it.

These four tools solve different problems. This is my practical shortlist based on their published features and the way I approach SEO work. I have not run a controlled test of every paid plan, so I will not pretend one won a race I never held.

What I look for before choosing a tool

First, I ask what is slowing the team down. Is it research? A weak brief? A draft that misses obvious questions? Or a pile of articles nobody has time to update? Then I check whether the tool helps with that job. A high content score means little if the page still avoids the customer's real question.

1. Surfer: a second set of eyes on a draft

Surfer is built around a content editor with SEO suggestions as you write. It belongs on my shortlist when writers know their subject but need a clearer view of related topics and on-page gaps.

What I like about this kind of tool is the nudge to revisit a thin section. What I watch for is the temptation to chase a score. If a suggested phrase makes the sentence worse, I leave it out. Readers do not hand out points for awkward wording.

2. Frase: getting from research to a useful brief

Frase brings research, briefs, writing and optimisation into one workflow. It looks useful when the hardest part is turning a broad topic into a clear assignment for a writer.

I add the things a search result cannot supply: customer questions, real examples, a screenshot or a point of view. A brief helps me organise the work. It cannot give me experience I have not had.

3. Clearscope: reviewing an existing article

Clearscope focuses on content optimisation. It fits a team with an editorial process that wants to improve pages already on the site.

When I review an old page, I do not start by adding words. I ask what has changed since it was written and what the reader still needs to know. A tool can spot a missing topic; I decide whether it belongs there.

4. Semrush Content Toolkit: keeping the whole process together

Semrush Content Toolkit covers ideas, briefs, drafting, optimisation and repurposing. It makes sense for a team that wants one place to move work from idea to approval.

I check the final copy carefully, especially when AI writes a first draft. Product details, figures and examples need a human check. “The tool wrote it” is not much comfort to a reader who acts on a wrong answer.

My pick for each job

My starting picks: Surfer for hands-on editing, Frase for research and briefs, Clearscope for refreshing an existing content library, and Semrush for a broader team process. To choose between two finalists, put the same real article through both. Compare what changed, how long it took and how much rewriting remained.

AI can save time. It does not choose your customers, interview them or build a credible point of view for you. If you want help deciding which pages your site actually needs, see how I work on SEO.

FAQ: AI SEO tools

What are AI SEO tools?

They are tools that use AI to help with SEO tasks such as research, briefs, writing or content review. They do not all do the same job. I start by naming the task I need help with, then choose a tool for that task.

What is the best AI SEO tool?

There is no single best choice for every team. Surfer is worth a look for editing, Frase for briefs, Clearscope for content reviews and Semrush for a wider workflow. Test two against the same article before paying for a year.

How can I use AI for SEO without publishing generic content?

Use it to sort research, draft an outline and find unanswered questions. Then add your own examples, check claims and edit the text until it sounds like you. I use AI to shorten the preparation, not to skip the thinking.

Can AI help with keyword research?

Yes, it can group ideas and suggest angles. I still verify search demand with a source such as Keyword Planner, inspect the results and check whether the query fits the business. A plausible keyword invented by a chatbot is still just a guess.

Is AI-generated content bad for SEO?

Using AI is not the issue by itself. Accuracy, originality and value to readers matter. Google says AI can help with research and structure, while mass-producing pages without added value may break its spam rules. I review every claim before publishing. Read Google's guidance.

Can AI write SEO titles and meta descriptions?

It can draft options quickly. I still check whether the title matches the page and whether the description gives someone a good reason to click. One clear sentence beats ten polished versions of the wrong promise.

Are free AI SEO tools enough for a small website?

Often, yes, at the start. Search Console and a careful manual review may tell you more than a paid AI subscription. Pay when a tool saves time on a repeated task or gives you data you cannot get from your current setup.

Can AI improve an old article?

It can point out gaps, dated sections and confusing wording. I first check the article's current queries, the page's purpose and what has changed in the topic. Then I update the useful parts. More text is not automatically an improvement.
