You’re missing a lot if you’re avoiding using SEO AI tools to improve your overall strategy! As AI popularity increases and search engines embrace generative AI, it’s up to us to adapt to the new trends. Yes, even Google releases updates in short periods to keep up with the current trends and improve how content is created. 

But does it mean it’s the end of the classic SEO we know? Surely, there are some significant changes, but one thing is still the same: Spotting relevant queries and creating user-oriented content to match their needs, issues, and questions. This approach applies to every industry, including eCommerce, SaaS, hospitality, IT, education, etc. 

Using AI tools for keyword research is a great way to understand the long-tail queries, the intent behind every keyword, and the best way to match them with the content. While the traditional tools may overwhelm you with data, AI ones are pretty straightforward. 

So, do you want to learn how to leverage premium and/or free AI tools for SEO analysis and extensive keyword research? Look no further!

How to Choose an AI SEO Tool?

Choosing an SEO tool powered by AI will help you spot the most relevant keywords, create opportunities from the content gaps, and improve the SEO performance of your website. 

But how do you choose the best AI for SEO? What features should it provide to prove its worth? Can you leverage free AI SEO tools only, or must you consider paying for them? Here are some factors to consider:

Needs and Goals

The first thing is what you need the SEO tool for and what are your short-term and long-term goals. Based on that, you can find fitting tools to improve your keyword research process, SEO and content audit, spot the underperforming posts on your site, or one that will brainstorm many content ideas. 

Most commercial SEO tools offer many features, but that means you either get a daily limit or must buy some of the paid plans to access it. But if you need keyword research only, you can leverage free tools or just the related search on search engines. 

Features and Capabilities

Free language models like ChatGPT and Bard can surely list keyword suggestions and even analyze provided content. But you must know how to prompt it, i.e., tell the LLM (large language model) what you want and expect. 

If you want to use a specialized AI SEO platform, you’ll have to compare the features and capabilities or sign up for a demo before committing to it. For example, tools like Ahrefs and SemRush will let you perform extensive keyword research and audit some websites, but features like AI-generated content and estimating content quality aren’t directly available. 

So, check the features and decide based on your needs and expectations. 

Compare Prices and Subscriptions

This is the most challenging decision to make. Once you’re sure you want to use SEO analysis tools together with keyword research, you need to spot the fitting ones and compare the prices and subscriptions. 

Be careful, and analyze their pricing plans. Do they offer a 7-day free trial, or maybe a 10-day free trial before buying the premium plan? What is their refund policy? Can you stop the subscription whenever you want? Does the price make for the profit you make?

All these elements will surely help you find the best AI-powered SEO tool for your business that covers many aspects of SEO, including keyword research and web performance analysis, and provides helpful insights. 

What is an AI SEO Keyword Generator?

AI keyword research tools or keyword generators use artificial intelligence to research and analyze data and help you generate an extensive keyword list with ranking keywords. 

Once you have the list, you can filter out the most relevant queries and check on their keyword difficulty, search volume, and traffic potential using traditional SEO tools. That way, you can create a SEO strategy based on the relevant queries but also enrich it with the suggestions the AI tool provided.

So, are you ready to leverage these AI-powered SEO tools (keyword generators) to scale your performance?

Here are some keyword suggestions tool SEO you can choose from:

When looking for AI SEO solutions, you can consider using ChatGPT and Bard. Still, they aren’t SEO tools by definition, and you’ll need to properly prompt your requirements in order to get what you’re looking for. 

So, let’s see how it works. 

ChatGPT

Is there anyone who doesn’t know what ChatGPT is? One of the most popular LLMs in the world gives you an option to write chat-like prompts and ask for help or assistance. 

You’ll often see it listed among the AI SEO trends because ChatGPT has a lifetime free version, and also a paid one. But if you know how to use the potential it offers, you can leverage the SEO capacities and perform a great keyword research. 

So, here’s an example of a prompt, and the result we got:

How to Master the Use of AI SEO Tools?

Every SEO strategy is based on an initial idea, goals, expectations, and estimations. So, you need to decide what you want to achieve and then leverage some of the mentioned AI-powered SEO tools.

A single tool won’t help a lot, so you must choose a few of them for a holistic approach. For example, the keywords generated with LLMs can be relevant for a broad topic, but you need to check if they match the content strategy, your product, or your intent. 

AI-generated outlines can be a nice start, but you still need to spot the opportunities for growth and winning great ranks that paid SEO tools give you.

Remember, creating helpful content that is also good to rank on search engines is not a simple process. The keywords resulting from keyword research will guide you through the whole strategy, helping you understand what your audience wants to know but also what you should do to signal the search engines you’re worth ranking.

Even then, you can’t expect huge changes overnight. You must keep working on your SEO strategy and holistic approach and track the progress. That way, you can improve some SEO aspects or change what doesn’t work for your niche or industry.
